ci(release): re-sign updater tarball after tauri-action's repack

tauri-action always re-packs Psysonic.app into .app.tar.gz after tauri
CLI finishes (regardless of includeUpdaterJson), so the .sig that tauri
CLI produces never matches the final tarball — and the sig tauri-action
was supposed to produce silently goes missing ("Signature not found for
the updater JSON. Skipping upload...").

Rather than fight the repack, sign the repacked tarball ourselves in a
follow-up step using `tauri signer sign` against the same private key
(from TAURI_SIGNING_PRIVATE_KEY), then upload the fresh .sig. tauri-
action still handles the DMG + .app.tar.gz upload; we only add the .sig.

Also removes an unused `std::rc::Rc` import in the vendored cpal patch.

+> **⚠️ Note for Windows users:** This is one of the last releases with an unsigned Windows installer. We are waiting for our code signing certificate and hope it will arrive within the next few days. The installer does not contain a virus — any warnings from Windows SmartScreen or antivirus software are false positives.

+> **🎉 macOS users:** Starting with **v1.34.15**, Psysonic can **update itself silently**. No more DMG downloading and dragging to Applications — the updater fetches the signed `.app` bundle, verifies the signature, replaces the app in place, and relaunches. Just click "Update" when the toast appears.
+
+## [1.34.16] - 2026-04-18
+
+### Fixed
+
+- **CI — Updater signature upload** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: tauri-action on macOS produces the `.app.tar.gz.sig` minisign signature locally but does not upload it as a release asset for cross-target builds, which caused the `latest.json` manifest generator to fail (no signature to embed). An explicit post-build step now finds the `.sig` under `src-tauri/target/*/release/bundle/macos/` and uploads it with the expected filename (`Psysonic_aarch64.app.tar.gz.sig` / `Psysonic_x64.app.tar.gz.sig`).
+
+## [1.34.15] - 2026-04-18
+
+### Added
+
+- **macOS — in-app auto-update** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The Tauri Updater plugin is now active on macOS. When a new release is available, clicking **Update** in the notification toast downloads the signed `.app.tar.gz` bundle, verifies its minisign signature against the bundled public key, replaces `/Applications/Psysonic.app` in place, and relaunches the app — all in one click, no Gatekeeper warnings, no manual DMG handling. Windows and Linux continue to use the existing "download installer / point to folder" flow until their signing pipelines are wired up.
+
+## [1.34.14] - 2026-04-18
+
+### Added
+
+- **macOS — signed and notarized builds** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: macOS releases are now signed with a Developer ID Application certificate and notarized by Apple. Gatekeeper no longer shows the "app from unidentified developer" dialog; the DMG opens and runs with a single click on both Apple Silicon and Intel Macs. Signing + notarization happens in CI on every release.
+
+- **WebKitGTK wheel scroll mode (Linux)** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#207](https://github.com/Psychotoxical/psysonic/pull/207))*: The Linux build now defaults to WebKitGTK's native smooth (kinetic) wheel scrolling and exposes a toggle in Settings → General to fall back to classic linear line-by-line scroll. Existing installs are migrated to smooth scrolling once, after which the toggle is fully user-controlled.
+
+### Fixed
+
+- **WCAG contrast audit — Middle-Earth theme** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Raised `--warning`, `--border`, `--text-muted`, `--positive`, and multiple component-level overrides (connection indicators, nav section labels, lyrics status, queue duration, player time, glass-panel muted text) to AA thresholds on all background variants. The warm bronze / aged-parchment palette is preserved — no cool tones introduced.
+
+- **WCAG contrast audit — Nucleo theme** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Darkened `--warning`, `--border`, `--text-muted`, and `--positive` tokens to reach AA on the warm cream palette; added a component-level override for the column resize grip (default `--ctp-surface1` was 1.08:1 on the card background, effectively invisible) using the new `--border` token at 2px width. Brass-and-parchment aesthetic preserved.

+## [1.34.13] - 2026-04-17
+
+### Added
+
+- **YouLyPlus — word-by-word synced lyrics (karaoke)** *(Issue [#172](https://github.com/Psychotoxical/psysonic/issues/172), by [@Psychotoxical](https://github.com/Psychotoxical))*: Settings → Lyrics now exposes a mode toggle between the existing **Standard** pipeline (Server tags + LRCLIB + Netease, configurable order) and a new **YouLyPlus** mode that fetches karaoke-style word-sync lyrics from the public `lyricsplus` aggregator (Apple Music / Spotify / Musixmatch / QQ Music). When a track has no YouLyPlus entry the app silently falls back to the Standard pipeline, so obscure titles still resolve. Active word highlighting in both the sidebar Lyrics pane and the Fullscreen Player. Five backend mirrors are tried on network failure; no API keys on the user side — subscription costs are borne by the lyricsplus operator.
+
+- **Static-only lyrics option** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: A new toggle renders synced lyrics as plain static text — no auto-scroll, no word highlighting — for users who prefer to read rather than follow. Works in both Standard and YouLyPlus modes.
+
+- **Discord Rich Presence — collapsible advanced options** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The *Fetch covers from Apple Music* toggle and the *Custom text templates* form are now tucked under a single collapsible **Advanced Discord options** header (default collapsed) that only appears when Discord Rich Presence is enabled. Reduces vertical noise in Settings → General for the common case.
+
+### Fixed
+
+- **macOS — spurious microphone permission prompt (real fix)** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The 1.34.12 attempt of removing `NSMicrophoneUsageDescription` did not actually suppress the prompt — on modern macOS, TCC fires at AudioUnit instantiation time, not at Info.plist level. Root cause: `cpal` (via `rodio`) instantiates an `AUHAL` output unit (`IOType::HalOutput`), which macOS classifies as input-capable even for playback-only apps. Psysonic now ships a vendored `cpal 0.15.3` at `src-tauri/patches/cpal-0.15.3/` wired via `[patch.crates-io]`; the patch forces `IOType::DefaultOutput` for all output streams, which never touches input and never triggers the mic dialog. **Tradeoff:** per-device output selection is a no-op on macOS — the stream always follows the system default (change via System Settings → Sound or the menu-bar speaker icon). Matches the behaviour of Apple Music and Spotify on macOS. Settings surfaces this with an explanatory notice on macOS and hides the device picker there.

+## [1.34.12] - 2026-04-17
+
+### Added
+
+- **Playback source indicator in Queue** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#201](https://github.com/Psychotoxical/psysonic/pull/201))*: The current-track tech strip in the Queue panel now shows a **source badge** indicating how the track was loaded: `stream` (live from server), `preloaded` (buffered before playback), or `cache` (served from local hot cache). Preload tracking is wired through the Rust audio engine so the badge reflects actual playback origin, not just current state.
+
+- **ReplayGain metadata in Queue tech strip** *(Issue [#195](https://github.com/Psychotoxical/psysonic/issues/195), contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#196](https://github.com/Psychotoxical/psysonic/pull/196))*: The current-track tech strip now shows track and album ReplayGain values alongside bitrate and format when the file contains gain tags.

+- **Discord Rich Presence enhancements** *(contributed by [@kveld9](https://github.com/kveld9), PR [#198](https://github.com/Psychotoxical/psysonic/pull/198))*: Discord Rich Presence received several improvements: dead/unused fields removed, the `{paused}` placeholder that Discord does not support was dropped, and a `timeChanged` invoke loop that fired redundantly on every progress tick was eliminated. The DRP timer is now accurate and stable.
+
+- **Context menu in Search results** *(contributed by [@kveld9](https://github.com/kveld9), PR [#191](https://github.com/Psychotoxical/psysonic/pull/191))*: Song rows in the Search panel now support the full right-click context menu (Play, Queue, Playlist, etc.) — previously search results were click-only with no context actions.
+
+- **Spotify CSV playlist import** *(contributed by [@kveld9](https://github.com/kveld9), PR [#190](https://github.com/Psychotoxical/psysonic/pull/190))*: Playlists exported from Spotify as CSV can now be imported directly into Psysonic. Tracks are matched by ISRC when available, with title/artist fallback. Unmatched tracks are listed in a report after import. Duplicate checking is done before writing.
+
+- **CLI completions and expanded player controls** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#187](https://github.com/Psychotoxical/psysonic/pull/187))*: The `psysonic` CLI gains shell completions for bash/fish/zsh/elvish, new subcommands for library browsing and audio device listing, a server switcher command, and an opaque play-ID scheme for stable track references. The tray icon on Linux no longer requires `libayatana-appindicator` / `libindicator` — it falls back gracefully when the library is absent.
+
+- **Albums and Playlists header redesign** *(contributed by [@kveld9](https://github.com/kveld9), PR [#186](https://github.com/Psychotoxical/psysonic/pull/186))*: The header sections on the Albums and Playlists pages have been redesigned for a cleaner, more consistent layout.
+
+- **Favorites page redesign** *(contributed by [@kveld9](https://github.com/kveld9), PR [#184](https://github.com/Psychotoxical/psysonic/pull/184))*: The Favorites page has been overhauled with sortable columns, a gender filter, an age range filter, and additional metadata columns.
+
+- **Split Mix navigation mode** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: A new toggle in Settings switches the Mix section between a single **Build a Mix** hub entry and **two separate sidebar entries** — Random Mix and Random Albums — for users who prefer direct access. Navigation items are now defined in `src/config/navItems.ts`; the toggle is stored as `randomNavMode` in authStore.
+
+- **Device Sync improvements** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Device Sync received several updates: a JSON manifest is now written to the device root on every sync (and read back automatically when the device is mounted); a **Cancel** button interrupts a running sync cleanly; a font picker was added to the sync page; sync status display was fixed; and the filename template builder now works correctly on all platforms.
+
+- **Radio — ICY StreamTitle forwarded to MPRIS** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: While playing internet radio, the current song title parsed from ICY `StreamTitle` metadata is now forwarded to MPRIS `xesam:title` on Linux so that the track name appears in desktop notification shells and media controls.
+
+- **Help page — expanded coverage** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Added missing help sections covering Device Sync, Internet Radio, CLI usage, Playlists, Infinite Queue, Lyrics sources, Audio device selection, Backup & Restore, and Now Playing details.
+
+- **Tracklist column reset and privacy policy** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: A reset button in the tracklist column picker restores the default column set. The Device Sync page received a cross-platform filename template fix. A privacy policy page was added documenting data usage for Last.fm, LRCLIB, NetEase, and Discord.
+
+### Fixed
+
+- **Streaming playback stability** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#200](https://github.com/Psychotoxical/psysonic/pull/200))*: Several edge cases in the Rust audio engine around stream start, mid-track seeking, and track transitions were hardened. Cache promotion (moving a preloaded track into the hot cache) is now safer under concurrent access. Stream decoder errors during transitions no longer leave the engine in a stuck state.
+
+- **CSV import reliability** *(contributed by [@kveld9](https://github.com/kveld9), PR [#199](https://github.com/Psychotoxical/psysonic/pull/199))*: The CSV import pipeline now guards the `ISRC` field type before calling `toUpperCase`, preventing a crash on rows with numeric or null ISRC values. The playlist public/private toggle in the edit modal (accidentally removed during a post-merge fix) is restored.
+
+- **Tracklist column picker** *(contributed by [@kveld9](https://github.com/kveld9), PR [#188](https://github.com/Psychotoxical/psysonic/pull/188) and PR [#192](https://github.com/Psychotoxical/psysonic/pull/192))*: Fixed a column picker overflow where the dropdown was clipped by the tracklist container. Also fixed column toggle state and alignment issues in the picker UI. An `overflow-x: visible` regression introduced in PR #188 was subsequently reverted.
+
+- **macOS — spurious microphone permission prompt** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Removed `NSMicrophoneUsageDescription` from `Info.plist`. It was inherited from an earlier Tauri template but Psysonic never uses the microphone; its presence caused macOS to show a permission dialog on first launch.
+
+- **Device Sync — auto-import and disconnect cleanup** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The sync manifest is now automatically imported when the Device Sync page is opened if a device with a manifest is already mounted. The sync file list is cleared when the device is disconnected.
+
+- **Audio — streaming decoder log labels** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#201](https://github.com/Psychotoxical/psysonic/pull/201))*: Rust log lines from the streaming decoder are now tagged with the source type, making it easier to distinguish stream vs. local decode paths in debug output.
+
+- **Theme — Latte and GTA readability** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Improved contrast and text readability in the Catppuccin Latte and GTA themes.
+
+- **i18n — missing `common.play` key** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: Added the `common.play` translation key to all 8 locales; it was missing after PR #186 which introduced its usage.
+
+### Removed
+
+- **Waveform seekbar — realtime waveform style** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The `realtime_waveform` CSS class and its associated style block were removed. This style was applied during live streaming and produced a low-quality rendering mode that was no longer needed after the streaming architecture improvements.
+
+---
+
+*Thank you to everyone who contributed to this release:*
+*[@cucadmuh](https://github.com/cucadmuh) for the playback source indicator, ReplayGain in the tech strip, streaming stability hardening, and CLI improvements — four substantial PRs.*
+*[@kveld9](https://github.com/kveld9) for the CSV import, search context menu, Discord RP enhancements, Favorites redesign, and header redesign — a very productive cycle.*
+

+
+## [1.34.11] - 2026-04-14
+
+### Added
+
+- **Opus audio playback** *(Issue [#180](https://github.com/Psychotoxical/psysonic/issues/180), contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#183](https://github.com/Psychotoxical/psysonic/pull/183))*: Psysonic can now decode Opus audio natively via `symphonia-adapter-libopus`, which bundles and compiles libopus from source. Previously `.opus` files were sent to the server for transcoding — a workaround that never worked reliably. Native decoding is now used directly; the server is no longer involved. Note: building from source requires `cmake` to be installed (see README).
+
+- **Device Sync — synchronise your library to USB and SD card players** *(Issue [#161](https://github.com/Psychotoxical/psysonic/issues/161), by [@Psychotoxical](https://github.com/Psychotoxical))*: A fully overhauled Device Sync page lets you copy music from your Navidrome library to any mounted USB drive or SD card. Browse albums via live search (300 ms debounce) or a random album selection. Choose a filename template (Artist/Album/Track format), pick a target folder, and review a pre-sync summary showing files to add, files to delete, and available space — including a warning if the device would run out of space after accounting for pending deletions. Already-synced files are detected and skipped automatically so incremental syncs are fast.
+
+- **3 visual toggles** *(contributed by [@kveld9](https://github.com/kveld9), PR [#181](https://github.com/Psychotoxical/psysonic/pull/181))*: Three new toggles in Settings → Appearance:
+  - **Cover art background** — enables/disables the blurred album art background in Album Detail and the Hero section.
+  - **Playlist cover photo** — shows/hides the cover collage at the top of Playlist Detail pages.
+  - **Show bitrate badge** — toggles the bitrate label displayed on tracks in the queue and track lists.
+
+- **8 community themes** *(contributed by [@kveld9](https://github.com/kveld9), PR [#182](https://github.com/Psychotoxical/psysonic/pull/182))*: A new **Community** theme group appears directly below Psysonic Themes in the Theme Picker, containing eight new themes: **AMOLED Black Pure** (pure black for OLED), **Monochrome Dark** (grayscale), **Amber Night** (warm golden amber), **Phosphor Green** (classic terminal green), **Midnight Blue** (deep blue), **Rose Dark** (pink/rose accents), **Sepia Dark** (warm cream sepia), and **Ice Blue** (cool cyan). Psysonic now ships with 75 themes across 9 groups.
+
+### Fixed
+
+- **HTTPS streaming failures and server URL trailing slash** *(Issue [#178](https://github.com/Psychotoxical/psysonic/issues/178), by [@Psychotoxical](https://github.com/Psychotoxical) with fix ported from PR [#179](https://github.com/Psychotoxical/psysonic/pull/179) by [@kveld9](https://github.com/kveld9))*: Two bugs that broke HTTPS server connections are now fixed. A trailing slash in the configured server URL caused double-slash stream URLs (`//rest/stream.view`) that reverse proxies like Caddy would reject, and also caused album browsing to return 0 results. Additionally, `reqwest` now loads the OS native certificate store alongside Mozilla's root store — fixing HTTPS streaming failures when the server certificate is signed by a local CA (e.g. Caddy's internal CA) that is trusted in the system keychain but not in Mozilla's bundle.
+
+- **Server display in Settings** *(by [@Psychotoxical](https://github.com/Psychotoxical))*: The server list in Settings → Servers now shows the URL and username on separate lines instead of a single truncated `username@url` string. Protocol prefixes (`http://`, `https://`) are stripped for cleaner display. HTTPS connections show a green lock icon.
+
+### Changed
+
+- **Waveform seekbar — live theme updates** *(contributed by [@kveld9](https://github.com/kveld9), PR [#182](https://github.com/Psychotoxical/psysonic/pull/182))*: The canvas-based seekbar now listens for `data-theme` attribute changes via `MutationObserver` and redraws immediately with the new theme colours. Switching themes no longer requires an app restart to update the waveform.
+
+---
+
+*Thank you to everyone who contributed to this release:*
+*[@cucadmuh](https://github.com/cucadmuh) for implementing native Opus decoding — a long-requested feature that finally makes `.opus` libraries fully playable.*
+*[@kveld9](https://github.com/kveld9) for three PRs in one release: the SSL/trailing-slash fix, visual customisation toggles, and eight new community themes with a live waveform update fix.*
+
+---
+
+## [1.34.10] - 2026-04-13
+
+### Added
+
+- **AppImage bundle for Linux** + X11/XWayland enforcement on all Linux packages: CI now builds `.AppImage` in addition to `.deb` and `.rpm`. `GDK_BACKEND=x11` and `WEBKIT_DISABLE_COMPOSITING_MODE=1` are set automatically at startup on all Linux packages — WebKitGTK on Wayland is unstable. Both environment variables are still overridable by setting them before launch.
+
+- **Audio output device selection** *(Issue [#169](https://github.com/Psychotoxical/psysonic/issues/169))*: Settings → Audio now shows a dropdown of all available output devices. The current OS default is pinned at the top with a label; a Refresh button re-enumerates silently. A device watcher detects hot-plug events and emits `audio:device-reset` after ~9 s of consecutive misses, preventing false positives on busy ALSA devices. On Linux, technical ALSA prefixes are stripped for display (`sysdefault:CARD=U192k` → `U192k`).
+
+- **Vision Dark & Vision Navy — colorblind-safe themes** *(Issue [#166](https://github.com/Psychotoxical/psysonic/issues/166))*: Two new themes using a Purple & Gold palette designed to be safe for Deuteranopia, Protanopia, and Tritanopia. Vision Dark pairs near-black `#0D0B12` with Gold `#FFD700` (~14.7:1 WCAG AAA); Vision Navy uses deep navy `#0A1628` + Gold (~14.5:1 WCAG AAA). Both appear under a new **Accessibility** group in the Theme Picker. These themes are a first step toward proper colorblind support and will be revised and expanded in upcoming releases — structural improvements such as secondary indicators and pattern/shape cues are still on the roadmap.
+
+- **Folder Browser — per-column filter & Shift+Enter queue append** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#165](https://github.com/Psychotoxical/psysonic/pull/165))*: Press Ctrl+F to open a filter field for the active Folder Browser column. Focus hands off cleanly between the filter input and the row list. Clearing a parent-column selection clears all right-side filters automatically. Press Shift+Enter on a filtered track list to **append** the visible tracks to the queue without replacing it.
+
+- **Keybindings — in-app modifier chords** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#167](https://github.com/Psychotoxical/psysonic/pull/167))*: In-app keybindings now support Ctrl/Alt/Shift+Key chords in addition to bare keys. The settings capture flow uses `buildInAppBinding`; the runtime handler uses `matchInAppBinding` and skips any chord already claimed as a global shortcut. Bare-key bindings still match without modifiers. Additionally, the seek forward/backward shortcuts now correctly interpret the configured value as seconds — previously the value was treated as a 0–1 progress fraction.
+
+- **Playlist management enhancements** *(contributed by [@kveld9](https://github.com/kveld9), PR [#168](https://github.com/Psychotoxical/psysonic/pull/168))*: Multi-select context-menu actions for Albums, Artists, and Playlists now include a bulk **Add to Playlist** submenu. The sidebar playlist section is now collapsible. The Artists page gains infinite scroll via `IntersectionObserver`. Submenus flip upward automatically when they would overflow the viewport bottom. A **Remove from Playlist** entry is now available in the Playlist Detail context menu.
+
+### Fixed
+
+- **Fullscreen Player — animation overhead in no-compositing mode** *(contributed by [@kilyabin](https://github.com/kilyabin), PR [#175](https://github.com/Psychotoxical/psysonic/pull/175))*: In software-rendering mode (`WEBKIT_DISABLE_COMPOSITING_MODE=1`) the mesh blob pan animations are now stopped (static gradients are preserved), the portrait drift animation is stopped, and `box-shadow` is removed from the seekbar played bar. The seekbar played bar width changes on every playback tick; triggering a full shadow repaint in software mode caused significant CPU overhead.
+
+- **Folder Browser — arrow keys with modifier keys** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#174](https://github.com/Psychotoxical/psysonic/pull/174))*: Column and list arrow-key handling is now skipped when any modifier key is held, preventing conflicts with browser focus navigation and OS-level shortcuts. Modifier detection uses both `nativeEvent` and `getModifierState` for WebKit/WebView2 compatibility.
+
+- **Audio output device — Linux stability** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#176](https://github.com/Psychotoxical/psysonic/pull/176))*: Pinned ALSA/cpal device IDs now stay stable when enumeration temporarily omits the active sink or returns an equivalent name. The Linux device-watcher no longer clears the pin based solely on missing list entries — only macOS and Windows treat repeated absence as "device unplugged". The Settings refresh flow calls `canonicalize` and refetches the list; an i18n label is now shown when the active device is no longer in the enumerated list.
+
+- **Login — server URL field** *(Issue [#171](https://github.com/Psychotoxical/psysonic/issues/171))*: The placeholder text in the Add Server form was previously a hardcoded English string. It is now fully localised and clarifies that `https://` URLs are accepted.
+
+- **Offline mode — non-blocking banner** *(Issue [#170](https://github.com/Psychotoxical/psysonic/issues/170))*: The full-screen blocking overlay shown when Psysonic starts without a cached library is replaced with a slim banner at the top of the content area. The banner includes a direct link to Server Settings so the user can fix the connection without navigating manually.
+

+
+## [1.34.9] - 2026-04-12
+
+### Added
+
+- **Multi-select in Playlist Detail & Favorites** *(Issue [#157](https://github.com/Psychotoxical/psysonic/issues/157))*: The same Ctrl/Cmd+Click multi-select system that was previously exclusive to album track lists is now available everywhere. Hold Ctrl (or ⌘ on macOS) to enter select mode, Shift+Click to range-select, click the header checkbox to toggle all. Selected tracks can be dragged as a group directly into the queue. A bulk action bar appears with **Add to Playlist** and **Clear selection** options. Works in Playlist Detail (main tracklist) and in the Favorites song list.
+
+- **"Open Artist" in context menu**: Song context menus now show an **Open Artist** entry directly below **Open Album**, navigating to the artist detail page. Previously only accessible via the tracklist artist link.
+
+- **"Add to Playlist" for Artists**: The context menu for artists now includes an **Add to Playlist** submenu. Psysonic fetches all albums from the artist and collects every track, then forwards them to the playlist picker — identical to the existing album-level submenu.
+
+- **Infinite queue — Instant Mix strategy** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#163](https://github.com/Psychotoxical/psysonic/pull/163))*: When Infinite Queue is enabled, Psysonic now builds the upcoming track list using the same artist-driven logic as Instant Mix. It fetches **Top Songs** and **Similar Songs** for the current track's artist, shuffles and deduplicates the pool, and only falls back to fully random songs when no artist-driven candidates are available. This results in much more coherent listening sessions that stay close to your current musical context.
+
+- **Fullscreen Player — appearance settings** *(contributed by [@kilyabin](https://github.com/kilyabin), PR [#156](https://github.com/Psychotoxical/psysonic/pull/156))*: Settings → Appearance → Fullscreen Player now offers a toggle to show/hide the artist portrait and a 0–80 % dimming slider for the background portrait.
+
+- **Build a Mix hub** *(contributed by [@kilyabin](https://github.com/kilyabin), PR [#155](https://github.com/Psychotoxical/psysonic/pull/155))*: The previous *Random Mix* and *Random Albums* sidebar entries have been merged into a single **Build a Mix** page (Wand icon) at `/random`. A landing card lets you choose between *Mix by Tracks* and *Mix by Albums*. Old routes remain fully functional.
+
+- **Spanish translation** *(contributed by [@Kveld9](https://github.com/Kveld9), PR [#159](https://github.com/Psychotoxical/psysonic/pull/159))*: Complete Spanish (es) locale with 964 translated strings. Psysonic now ships in 8 languages: English, German, French, Dutch, Chinese, Norwegian, Russian, and Spanish.
+
+- **Column-header sorting for Albums & Playlists** *(contributed by [@Kveld9](https://github.com/Kveld9), PR [#160](https://github.com/Psychotoxical/psysonic/pull/160))*: Track lists in Album Detail and Playlist Detail now support click-to-sort directly on the column headers. Three-click cycle: ascending → descending → natural order. Sortable columns: Title, Artist, Album, Favourite, Rating, Duration. The active column is shown bold with a ▲/▼ indicator.
+
+- **Folder Browser — keyboard navigation & context menus** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#158](https://github.com/Psychotoxical/psysonic/pull/158))*: Full keyboard navigation in the Folder Browser with arrow keys, Enter to open, and Ctrl+Enter to open the context menu. Context menus for all row types include keyboard-operable submenus and star-rating control via arrow keys. The now-playing path is visually emphasized and updates live. Adaptive column layout prioritizes right-side visibility for deep directory trees. A new configurable *Open Folder Browser* keybinding is available in Settings → Keyboard.
+
+- **PLS/M3U playlist resolution for Internet Radio**: Stations configured with a `.pls` or `.m3u`/`.m3u8` URL (e.g. SomaFM, schizoid.in) are now resolved to their first direct stream URL before playback. ICY metadata fetching also auto-resolves playlist URLs. Previously these stations would fail to play or show no track info.
+
+- **Lyrics sources — configurable order & per-source toggle**: The old *Server First* toggle has been replaced with a full drag-to-reorder list in Settings → General. Three sources — **Server** (embedded/OpenSubsonic), **LRCLIB**, and **Netease Cloud Music** — can each be individually enabled or disabled, and their priority order is fully customisable. Embedded SYLT tags from local files always win unconditionally.
+
+- **ReplayGain Pre-Gain & Fallback** *(audio)*: Two new sliders in Settings → Audio → ReplayGain:
+  - **Pre-Gain** (0–+6 dB): added on top of every ReplayGain-tagged track for users who prefer a louder default.
+  - **Fallback Gain** (−6–0 dB): applied to untagged tracks and internet radio streams, preventing volume jumps when switching between tagged and untagged content.
+
+- **Context-aware Remix button in Build a Mix**: When a genre filter is active, the Remix button now re-fetches the same genre instead of resetting to the full library pool. An *All Songs* chip is available as the first genre option to return to the global mix without leaving the page.
+
+- **AlbumTrackList multi-select & psyDnD** *(tracklist polish)*: Album track lists now support full multi-select with Ctrl/Cmd+Click, Shift+Click range selection, and drag-to-queue for multiple tracks simultaneously. The `TrackRow` component is `React.memo` with fine-grained Zustand selectors, so only the toggled row re-renders on selection change (O(1)).
+
+- **Mute/unmute restores previous volume**: The mute button in the player bar now restores the volume to its level before muting instead of always jumping to 70 %.
+
+### Fixed
+
+- **Statistics — accurate counts for large libraries**: The statistics page was previously capped at 10 pages (≈ 5,000 albums), causing incorrect totals on larger libraries. The pagination loop now runs until the server returns a partial page, regardless of library size. Sort type changed to `alphabeticalByName` for stable pagination.
+
+- **Statistics — Artists count tooltip**: The Artists card now shows a tooltip (dotted underline, cursor: help) explaining that the count reflects album artists only — a Subsonic API limitation. Featured or guest artists who do not have their own album are not counted. The tooltip is localised in all 8 languages.
+
+- **Artists page — alphabet navigation hover effect**: The A–Z filter buttons had inline styles that prevented `:hover` CSS from applying. Buttons are now styled via `.artists-alpha-btn` CSS class with an accent-coloured hover highlight and a subtle glow ring.
+
+- **Hot Cache — eviction & prefetch budget**: Eviction now correctly keeps only the current and next track; prefetch fetches up to five tracks when under the size cap but always fetches the immediate next; the previous current track is given a grace period until the debounce fires; eviction runs immediately on MB limit or folder changes; the cap is re-read after each download completes. Live disk usage is now shown on the Audio settings page.
+
+- **Hot Cache + Preload — mutual exclusion on rehydration**: Users who had both Hot Cache and Preload enabled before the mutual-exclusion rule was introduced will have both automatically reset to off on first launch, preventing a conflicting state.
+
+- **Fullscreen Player — Linux compositing performance** *(contributed by [@kilyabin](https://github.com/kilyabin), PR [#156](https://github.com/Psychotoxical/psysonic/pull/156))*: A new `no_compositing_mode` Tauri command detects Linux software-rendering mode and adds an `html.no-compositing` class, which swaps GPU-only CSS effects (`backdrop-filter`, `filter`, `mask-image`) for software-friendly equivalents throughout the fullscreen player.
+
+- **Fullscreen Player — long lyric lines wrapping**: Long words in lyric lines now wrap correctly instead of overflowing the container.
+
+- **Russian locale** *(contributed by [@kilyabin](https://github.com/kilyabin), PR [#148](https://github.com/Psychotoxical/psysonic/pull/148))*: Numerous translation improvements across the application, replacing machine-translated or awkward phrasings with natural Russian.
+
+- **npm audit vulnerabilities**: Updated `axios` and `vite` to address reported security advisories.
+
+### Changed
+
+- **"Remove from Queue" context menu item** now has a **Trash** icon, matching the destructive action style of other delete operations.
+- **Playlist Detail — filter-mode drag**: Rows in a filtered/sorted playlist view can now be dragged to the queue as single songs (previously dragging was disabled entirely in filter mode).
+- **Infinite queue deduplication**: Tracks already present in the queue are excluded from the candidate pool, preventing the same song from appearing twice in a row during Infinite Queue sessions.
+

+
+---
+
+## [1.34.8] - 2026-04-10
+
+### Added
+
+- **Netease Cloud Music Lyrics** *(opt-in)*: Netease Cloud Music can now be enabled in Settings → General as a last-resort lyrics fallback. It only fires when neither the server nor LRCLIB return results — the existing lyrics chain is completely unaffected. Particularly useful for Asian and international music. Chinese metadata lines (作词/作曲/编曲 etc.) are automatically stripped from the LRC output.
+
+- **Navidrome AudioMuse-AI Integration** *(contributed by [@cucadmuh](https://github.com/cucadmuh), PR [#147](https://github.com/Psychotoxical/psysonic/pull/147))*: Psysonic now  supports [AudioMuse-AI](https://github.com/cucadmuh/audiomuse-ai) if it is active on the Navidrome server and uses it for Random Mix, Similar Artists, and Instant Mix. No configuration required — Psysonic keeps its existing behavior when AudioMuse is unavailable. Also includes an Instant Mix probe, ping identity, and improved UX for AudioMuse-specific actions.
+
+- **ICY metadata & AzuraCast radio** *(contributed by [@nisrael](https://github.com/nisrael), PR [#146](https://github.com/Psychotoxical/psysonic/pull/146))*: Internet radio now displays live track metadata from ICY streams. AzuraCast stations are supported with extended now-playing information.
+
+- **Automatic audio device switching**: Psysonic now detects newly connected or changed audio output devices and switches to them automatically — no app restart required.
+
+### Fixed
+
+- **Multi-artist tracks**: Tracks with multiple artists (OpenSubsonic `artists[]` field, e.g. semicolon-separated entries) now display each artist individually. Artists with their own profile page are clickable links; artists without one appear as plain text. Separated by `·`.
+
+- **Gapless + Preload Gate**: The gapless chain and the preload gate now run on separate paths. Previously both could fire simultaneously, causing a brief black flash on track change.
+
+- **Replay Gain — missing album gain**: When no album gain tag is present, Psysonic now correctly falls back to track gain instead of skipping gain correction entirely.
+
+- **Statistics — music library scope**: Genre insights now respect the currently selected music library. Fetch results are cached to avoid redundant server requests. Playback durations are displayed in localized units.
+
+- **Russian locale**: "Most Played" in the sidebar, home page, and page title now uses «Популярное».
+
+### Changed
+
+- **"Reset to defaults" buttons** in Settings → Input are now styled as warning buttons (red border).
+- **Lyrics button** removed from the player bar (redundant with the queue panel tab).
+- **Icons**: Advanced search now uses the `TextSearch` icon; artist bio button now uses `Highlighter`.
+- **Album chip** in the album detail header is now opaque across all themes.
+- **Hot Cache and Hi-Res Audio**: Alpha badges removed — both features are production-ready.
+- **CPU optimisations**: Next-track buffering and preload settings have been consolidated into a unified control.
+
+### Theme Fixes
+
+- **Middle Earth**: Removed vertical stripe pattern from sidebar; improved queue artist contrast on hover; fixed album detail artist colour, bio text, and "Read more" link readability; "Next Tracks" divider label is now lighter.
+- **Toy Tale**: Fixed sidebar section labels (System/Library), queue tab buttons (Lyrics/Queue), inactive artist text, and "Next Tracks" divider label — all were too dark to read.
+- **Tetrastack**: Raised all purple and blue palette values (`#a020f0` → `#c070ff`, `#0060f0` → `#4090ff`); raised `--text-muted` from `#3a3a6a` to `#7878b8` — affected settings descriptions, artist names in tracklists, and queue labels.
+- **Horde & Alliance**: Removed repeating horizontal line pattern from sidebar.

+
+## [1.34.7] - 2026-04-09
+
+### Added
+
+- **Windows — Taskbar Thumbnail Toolbar**: Prev / Play-Pause / Next media buttons now appear in the Windows taskbar thumbnail preview (the popup that appears when hovering over the taskbar icon). Buttons emit the same `media:*` events as the tray menu and souvlaki. The Play/Pause icon swaps in real-time as playback state changes.
+
+- **Windows — High-quality taskbar icons**: The taskbar thumbnail toolbar icons are now loaded from embedded `.ico` assets (`play.ico`, `pause.ico`, `prev.ico`, `next.ico`) via `CreateIconFromResourceEx`, replacing the previous monochrome GDI drawing code. All four icons are properly cleaned up on window destruction.
+
+- **Professional update modal**: The in-app updater now shows a polished modal with the full release changelog, a **Skip this version** option, and an OS-aware direct download button (`.dmg` on macOS, `.exe` on Windows, `.deb`/`.rpm` on Linux) as a fallback if the auto-update fails. The modal is fully localised in all 7 supported languages.
+
+- **Self-hosted fonts — no internet required**: All 10 UI fonts are now shipped as WOFF2 files bundled into the app via `@fontsource-variable` npm packages. The previous Google Fonts CDN dependency has been removed entirely — Psysonic now renders correctly with no internet connection and without any external requests on startup.
+
+- **Help — 11 new FAQ entries**: The Help page covers previously undocumented features across Ratings (how to rate songs/albums/artists, removing a rating, Skip-to-1★, rating filter for mixes), Folder Browser, Theme Scheduler, UI Scale, Seekbar styles, AutoEQ, Replay Gain, Hot Cache, and offline playlist caching. All 7 locales updated.
+
+### Fixed
+
+- **Embedded lyrics (MP3 & FLAC)**: A new `get_embedded_lyrics` Tauri command reads lyrics tags directly from local files — `SYLT`/`USLT` frames for MP3 (via the `id3` crate) and `SYNCEDLYRICS`/`LYRICS` tags for FLAC (via `lofty`). Additionally: the LRC parser now correctly handles timestamps without fractional seconds (e.g. `[01:23]`), and the Subsonic structured-lyrics parser now accepts both `synced` and `issynced` field names for compatibility with different server versions.
+
+- **Linux — player bar disappearing at high zoom / small window sizes**: All `grid-template-rows` definitions now use `minmax(0, 1fr)` instead of bare `1fr`, and the `min-height: 720px` constraint on the app shell has been removed. The player bar no longer gets pushed off-screen when the window is small or the UI scale is above 100 %.
+
+- **Windows — "Open folder" in Settings crashing**: The Settings page uses a Rust `open_folder` command instead of the Tauri `shell:open` API, which was blocked by the capability scope on Windows for local paths.
+
+- **macOS — Artist Radio crashing WKWebView after ~10 minutes**: Storing `currentTime` in the persisted Zustand state caused up to ~1,200 synchronous `localStorage.setItem` calls per radio session, eventually crashing the WKWebView SQLite backend. `currentTime` has been removed from the persist partializer. Old played radio tracks are also now trimmed from the queue (keeping the last 5) to cap the localStorage payload during queue top-up.
+
+- **Artist Radio — predictable track order**: The initial Artist Radio queue is now shuffled via Fisher-Yates, so positions 2+ draw from similar-artist tracks in a random order rather than always playing the server's top-5 tracks in sequence.
+
+- **Internet Radio — stall / buffering recovery**: Stall events on the HTML5 `<audio>` element now trigger automatic reconnection (up to 5 retries), recovering from transient network interruptions without requiring a manual restart.
+
+- **Corrupt MP3s — VLC-style frame tolerance**: The audio decoder now tolerates up to 100 consecutive bad frames before giving up (previously 3), matching VLC's behavior for files with invalid `main_data` offset frames. Frame-drop log messages are suppressed in release builds.
+
+- **Statistics — album/song totals respect selected music library**: Album and track counts on the Statistics page were previously derived from `getGenres()`, which is not scoped to the active music folder. Both counts are now derived from the same paginated `getAlbumList` pass used for playtime, with the same 5,000-album cap and a `≥` prefix when capped. *(PR [#138](https://github.com/Psychotoxical/psysonic/pull/138) by [@cucadmuh](https://github.com/cucadmuh))*
+
+- **Fullscreen — resize grips visible in native fullscreen**: Resize grips are now hidden whenever the window enters native fullscreen on all platforms (previously only tracked on Linux). An initial check on mount also catches windows that start in a maximized or fullscreen state.
+
+- **Albums page — year filter input height**: The "From year" / "To year" inputs in the Albums filter bar now match the height and font size of adjacent buttons, fixing the mixed-height row introduced in v1.34.4.
+
+- **Russian locale — missing lyrics-source strings**: The `lyricsServerFirst` and related settings strings were not translated in the Russian locale. *(PR [#140](https://github.com/Psychotoxical/psysonic/pull/140) by [@kilyabin](https://github.com/kilyabin))*

+## [1.34.6] - 2026-04-08
+
+> I'm sorry this is already the third release today — every time we shipped a critical fix, another critical issue surfaced. Hopefully this one holds. 🤞
+
+### 🚨 Critical Fix
+
+- **ZIP downloads no longer freeze the UI**: All ZIP downloads (Album Detail, Playlist Detail, Albums, New Releases, Random Albums) previously buffered the entire file in the JS heap via `fetch + blob + arrayBuffer`, which caused the app to become completely unresponsive for large downloads (e.g. a 600-song, 7 GB playlist). Downloads now stream directly to disk via the Rust backend (`invoke('download_zip')`), matching the existing single-album download behavior. Progress is shown in the download overlay (bottom right).
+
+- **Offline cache downloads no longer freeze the UI**: Caching a large playlist (600+ songs) triggered up to ~1,200 synchronous `localStorage.setItem` calls as Zustand's `persist` middleware wrote on every state update. Transient download job state has been moved to a new non-persisted store (`offlineJobStore`), reducing localStorage writes for an entire download to **2** regardless of playlist size.
+
+### Added
+
+- **Playlist offline toggle**: When a playlist is already cached offline, clicking the cache button now removes it from the offline cache (shown with a red trash icon) instead of re-downloading it.
+
+### Fixed
+
+- **Home page — "Recently Added" section title** now links to `/new-releases` instead of `/albums`.
+
+---
+
+## [1.34.5] - 2026-04-08
+
+### 🚨 Critical Fix
+
+- **Massive API request flood fixed** *(closes [#133](https://github.com/Psychotoxical/psysonic/issues/133))*: Psysonic was generating 15,000+ background requests per day, filling reverse-proxy access logs (Traefik, nginx) and in some cases crashing the proxy entirely. Four root causes identified and resolved:
+  - **Now Playing polling**: Was firing every 10 seconds unconditionally — even when minimized or the dropdown was closed. Now only polls while the dropdown is open, and respects the Page Visibility API to pause immediately when the window is hidden.
+  - **Connection check interval**: Reduced from every 30 seconds to every **120 seconds** (4× reduction).
+  - **Queue sync debounce**: Increased from 1.5 s to **5 s**, preventing request bursts when skipping rapidly through tracks.
+  - **Rating prefetch cache**: Artist and album ratings are now cached in memory for **7 minutes**. Repeated page loads (Random Albums, Random Mix) no longer re-fetch ratings that were just retrieved.
+
+### Added
+
+- **Theme Scheduler** *(Settings → Appearance)*: Automatically switches the active theme at configurable times of day. Two time slots (e.g. a light theme during the day, a dark one at night). English locale displays hours in 12-hour AM/PM format; all other languages use 24-hour format.
+
+- **Theme Scheduler hint**: When the scheduler is active, a notice appears at the top of the Theme Picker explaining why manually selecting a theme has no immediate effect.
+
+- **UI Scale** *(Settings → Appearance)*: Adjust the global interface scale (80 % – 125 %) without changing the system font size.
+
+- **Folder Browser**: New sidebar section with Miller-columns directory navigation. Browse the server's music folder tree and play or queue folders directly.
+
+- **Seekbar — Waveform fade edges**: The Waveform seekbar style now fades out at both ends, giving it a cleaner, less abrupt look.
+
+- **Cover art fallback logo**: When a cover art image fails to load (broken URL, server error), the Psysonic logo is shown as a placeholder instead of a broken image icon.
+
+- **Tiling WM support** *(PR [#134](https://github.com/Psychotoxical/psysonic/pull/134))*: On tiling window managers (Hyprland, Sway, i3, bspwm, AwesomeWM, etc.) the custom title bar is automatically hidden — the WM manages window decorations. The title bar toggle in Settings is also hidden on tiling WMs. Detection is based on environment variables (`HYPRLAND_INSTANCE_SIGNATURE`, `SWAYSOCK`, `I3SOCK`, `XDG_CURRENT_DESKTOP`).
+
+### Changed
+
+- **Custom title bar disabled by default**: New installations start with the native OS title bar. Existing users keep their saved preference.
+
+### Fixed
+
+- **Custom title bar (Linux) — drag & resize**: Window dragging via the title bar now works correctly (missing Tauri `core:window:allow-start-dragging` capability was silently blocking it). CSS resize grips are now shown at the bottom corners to compensate for the removed native GTK grips. The title bar no longer misplaces itself when the window is resized to a small width (mobile-grid layout now includes the title bar row).
+
+- **Fullscreen Player — accent color delay**: The dynamic accent color extracted from album artwork now appears in ~200–300 ms instead of up to 18 seconds. The previous implementation queued the cover fetch behind up to 5 concurrent image loads via the app-wide image cache. It now fetches the cover directly and independently. The extracted color is also cached per cover ID, so switching between tracks on the same album is instant.
+
+- **Artist Detail page — slow initial render** *(closes [#132](https://github.com/Psychotoxical/psysonic/issues/132))*: Artist info and biography are now fetched independently of the main artist data, so the page renders immediately and the bio fades in once available. Previously, a slow `getArtistInfo` response blocked the entire page from rendering.
+
+- **Seekbar — Pulse Wave & Retro Tape styles**: Pulse Wave no longer leaves a stray connecting line at the playhead position. Retro Tape's rolling wheel is now anchored at the playhead instead of the center of the bar.
+
+- **Statistics — Top Rated Songs/Artists sections removed**: These sections were incorrectly added in v1.34.4 and have been removed. All other rating features from that release remain fully intact.
+
+---
+
+## [1.34.4] - 2026-04-08
+
+### Added
+
+- **Entity ratings** *(PR [#130](https://github.com/Psychotoxical/psysonic/pull/130))*: Full star-rating support (1–5 ★) for songs, albums, and artists via the OpenSubsonic `setRating` API. Ratings are shown and editable in the album track list, artist detail page, and the Favorites song list. A new shared `StarRating` component is used consistently across all surfaces. Requires an OpenSubsonic-compatible server (e.g. Navidrome ≥ 0.53).
+
+- **Song ratings — context menu & player bar**: Songs can additionally be rated directly from the **right-click context menu** and from the **player bar** (below the artist name), with optimistic updates reflected immediately across all views.
+
+- **Skip-to-1★** *(PR [#130](https://github.com/Psychotoxical/psysonic/pull/130))*: Automatically assigns a 1-star rating to a song after it has been manually skipped a configurable number of consecutive times. This skip count threshold can be enabled and adjusted in Settings → Ratings.
+
+- **Mix minimum rating filter** *(PR [#130](https://github.com/Psychotoxical/psysonic/pull/130))*: Random Mix and Home Quick Mix can now be filtered by minimum rating per entity type (song / album / artist). Configure thresholds in Settings → Ratings.
+
+- **Statistics — Top Rated Songs & Artists**: New "Top Rated Songs" and "Top Rated Artists" sections on the Statistics page, derived from starred items with a `userRating > 0`. Lists update live as ratings are changed without a page reload.
+
+- **Seekbar styles — 5 new styles**: Added Neon Glow, Pulse Wave, Particle Trail, Liquid Fill, and Retro Tape. Animated styles run a dedicated `requestAnimationFrame` loop. The style picker in Settings shows an animated live preview for each style.
+
+- **Custom title bar (Linux)**: Optional custom title bar with now-playing display (song title + artist, live-updating). Replaces the native GTK decoration when enabled. Automatically hides in native fullscreen (F11). Can be toggled in Settings → Appearance.
+
+- **Album multi-select**: Albums, New Releases, and Random Albums pages now support multi-select mode. Selected albums can be batch-queued or enqueued.
+
+- **Most Played — compilation filter**: New toggle on the Most Played page to hide compilation artists from the Top Artists list.
+
+- **Scroll reset on navigation**: The content area now scrolls back to the top automatically on every route change.
+
+### Fixed
+
+- **Backup**: The `psysonic_home` key is now included in the settings backup export.
+
+### i18n
+
+- New keys for seekbar styles, entity ratings, rating sections (Settings + Statistics), and entity rating support added to all 7 languages (EN, DE, FR, NL, ZH, NB, RU).
+
+---
+
+## [1.34.3] - 2026-04-07
+
+### Added
+
+- **Most Played page** *(closes [#86](https://github.com/Psychotoxical/psysonic/issues/86))*: New dedicated page accessible via the sidebar (TrendingUp icon, `/most-played`). Shows **Top Artists** (ranked by total play count, derived by aggregating album play counts per artist) and a paginated **Top Albums** list with cover art, play count, sort toggle (most/fewest first), and a Load More button.
+
+- **Playlist ZIP download** *(closes [#127](https://github.com/Psychotoxical/psysonic/issues/127))*: Download (ZIP) button in the playlist hero header — same UX as album download. Uses the Subsonic `/rest/download.view` endpoint with the playlist ID, shows a progress bar during transfer, and remembers the last used folder.
+
+- **Fullscreen Player — adaptive accent color**: Extracts the most vibrant pixel from the current album cover (8×8 Canvas downscale, max-HSL-saturation) and applies a WCAG 4.5:1-compliant accent as `--dynamic-fs-accent`. Song title, play button, seekbar, active states, background mesh blobs, and cover art glow all transition smoothly to the extracted color. Resets to the theme accent when the player closes.
+
+- **Dracula theme**: Added to the Open Source Classics group.
+
+- **Discord Rich Presence — Apple Music cover opt-in**: iTunes artwork lookup is now disabled by default. A new toggle in Settings → Integrations ("Fetch covers from Apple Music for Discord") must be explicitly enabled — it sends artist and album name to Apple's search API to find cover art for the Discord profile.
+
+- **Discord Rich Presence — Paused state**: When playback is paused, the Discord presence now shows "Paused" as the status text.
+
+### Fixed
+
+- **M4A playback — older iTunes-purchased files**: Files with an embedded MJPEG cover-art stream and an `iTunSMPB` gapless tag now play correctly. The Symphonia isomp4 patch skips malformed trak atoms gracefully; `parse_gapless_info` now searches for the `" 00000000 "` sentinel to skip the 16-byte binary `data`-atom header, correctly extracting encoder delay and total sample count.
+
+### i18n
+
+- New keys for the Most Played page, playlist download, and Discord Apple Music opt-in added to all 7 languages (EN, DE, FR, NL, ZH, NB, RU).
+
+---
+
+## [1.34.2] - 2026-04-07
+
+### Added
+
+- **M4A / ALAC / AAC-LC support** *(closes [#51](https://github.com/Psychotoxical/psysonic/issues/51))*: Apple Lossless (ALAC) and AAC-LC files in M4A containers are now decoded natively by the Rust audio engine (Symphonia) without requiring server-side transcoding.
+
+- **Per-server music folder filter** *(PR [#125](https://github.com/Psychotoxical/psysonic/pull/125) by [@cucadmuh](https://github.com/cucadmuh))*: Users with multiple music libraries on their Navidrome server can now scope browsing to a single folder. A dropdown in the sidebar (visible only when more than one library exists) lets you pick a folder or switch back to "All Libraries". The selection is persisted per server and automatically resets to "All" if the selected folder is no longer available.
+
+- **Hi-Res / Bit-Perfect Playback** *(Alpha)*: New opt-in toggle in Settings → Playback. When enabled, the audio output stream is re-opened at the file's native sample rate (e.g. 88.2 kHz, 96 kHz) — bypassing rodio's internal resampler for a bit-perfect signal path. Disabled by default (safe 44.1 kHz mode). Includes ALSA/PipeWire underrun hardening: scaled quantum size, 500 ms sink pre-fill at high rates, and scheduler priority escalation only when needed.
+
+- **Hot Playback Cache** *(Alpha, PR [#123](https://github.com/Psychotoxical/psysonic/pull/123) by [@cucadmuh](https://github.com/cucadmuh))*: Configurable on-disk prefetch cache for the next track in the queue. Reduces playback latency on slow or metered connections. Toggle and directory can be configured in Settings → Storage.
+
+### Changed
+
+- **Fullscreen Player — info block reworked**: The track title is now the dominant element (large, bold, accent color) and sits above the artist name (small, muted). Matches community feedback on visual hierarchy.
+
+- **Fullscreen lyrics — line wrapping**: Long lyric lines now wrap onto a second line instead of being truncated. Slot height increased from 3.6 vh to 6 vh to accommodate two-line entries without breaking rail positioning.
+
+- **Update notifications**: Removed the Tauri auto-updater (in-app download and install). The app now shows a simple dismissible toast when a newer version is detected on GitHub, with direct links to the [GitHub Releases page](https://github.com/Psychotoxical/psysonic/releases/latest) and the [Psysonic website](https://psysonic.psychotoxic.eu/#downloads). No signing keys, no update manifests.
+
+### Fixed
+
+- **Standard mode CPU usage**: Playing a 44.1 kHz MP3 with Hi-Res disabled no longer triggers an unnecessary audio device re-open on every track start. MSS read-ahead buffer reduced from 4 MB to 512 KB for standard-rate files. Background prefetch is now throttled by 8 s to avoid competing with playback startup. Combined, these changes reduce idle CPU from ~6–10 % to ~2–3 % on a modern machine.
+
+- **Hi-Res toggle — stream rate not restored**: Toggling Hi-Res off while a track was playing at 88.2 or 96 kHz left the output stream at the high rate for subsequent tracks. The device's default rate is now restored on the next play.
+
+- **Fullscreen lyrics — CPU spikes on line transitions**: Animating `font-weight` in CSS triggered a full layout reflow on every animation frame. Removed `font-weight` from the transition list; active-line emphasis now uses `transform: scaleX(1.015)` (compositor-only). Added `contain: layout style` to the overlay to isolate reflows from the rest of the page.
+
+### i18n
+
+- New keys for Hi-Res playback settings and music folder filter added to all 7 languages (EN, DE, FR, NL, ZH, NB, RU).
+
+---
+
+## [1.34.1] - 2026-04-06
+
+### Added
+
+- **Fullscreen Player — Synced Lyrics Overlay**: Synced lyrics are now displayed directly in the Fullscreen Player as an animated 5-line rail with a soft fade mask at the top and bottom edges. Click any visible line to seek to that position. Toggle the overlay on/off with the new microphone icon button next to the heart — preference is persisted.
+
+  > **Note:** The overlay currently requires synced (timestamped) lyrics. Support for unsynced lyrics in the Fullscreen Player is planned for a future release.
+
+- **Embedded Lyrics & LRC support**: The app now fetches lyrics from two sources using the shared `useLyrics` hook (used by both the Lyrics Pane and the Fullscreen overlay):
+  - **Server-embedded lyrics** via the OpenSubsonic `getLyricsBySongId` endpoint — reads timestamped or plain lyrics baked directly into the audio file's tags (Navidrome 0.53+).
+  - **LRCLIB** — external LRC lookup as fallback (or primary, configurable in Settings → Playback).
+  Both sources share a module-level cache so switching between the Lyrics Pane and the Fullscreen Player never triggers a second network request.
+
+- **Artist Image Upload**: A camera overlay now appears when hovering the artist portrait on the Artist page. Clicking it opens a file picker and uploads the image directly to your server.
+
+  > **Requires `EnableArtworkUpload = true`** in your Navidrome configuration (new option in Navidrome [#5110](https://github.com/navidrome/navidrome/issues/5110) / [#5198](https://github.com/navidrome/navidrome/issues/5198) — default: `true`). The same requirement applies to the existing Radio Station cover upload.
+
+- **Discord Rich Presence — Album Cover Art**: Album artwork is now displayed in Discord's Rich Presence card. Because Subsonic cover URLs require authentication (and can't be accessed by Discord directly), artwork is fetched from the iTunes Search API using a 3-strategy search (exact → relaxed → track-title fallback), cached for 1 hour, and passed as a direct URL to Discord. Falls back to the static Psysonic asset when no match is found.
+- **Nightfox themes** *(PR [#112](https://github.com/Psychotoxical/psysonic/pull/112) by [@nisrael](https://github.com/nisrael))*: Six themes from the [nightfox.nvim](https://github.com/EdenEast/nightfox.nvim) palette have been added to the **Open Source Classics** group — Dawnfox, Dayfox, Nightfox, Nordfox, Carbonfox, and Terafox.
+- **Auto-install script** *(PR [#121](https://github.com/Psychotoxical/psysonic/pull/121) by [@kilyabin](https://github.com/kilyabin))*: `install.sh` now supports Debian/Ubuntu (`.deb`) and RHEL/Fedora (`.rpm`) — automatically detects the distro, downloads the correct package from the latest release, and installs it.
+
+### Changed
+
+- **Fullscreen Player — performance overhaul**:
+  - `FsArt` (cover art) and `FsLyrics` are now isolated `memo` components — unrelated state changes no longer trigger their re-renders.
+  - Cover crossfade uses an `onLoad` DOM event instead of `new Image()` preloading. This avoids a React batching edge case where both state updates were flushed together and the browser never saw the `opacity: 0` starting state, preventing the CSS transition from firing.
+  - `useCachedUrl(..., true)` passes the raw URL as an immediate fallback — the image starts fetching from the network instantly while IndexedDB resolves the blob in the background.
+  - Lyrics slot height is stored in a `useRef` and updated only on `resize` — eliminates repeated `window.innerHeight` layout reads on every render.
+  - Mouse-move handler is throttled to 200 ms.
+- **Artist page — biography**: The bio text is now collapsed by default with a *Read more* / *Show less* toggle button, keeping the page layout clean for artists with long bios.
+- **Settings — Logout button**: Moved from the System tab to the bottom of the Server tab, styled as a danger button (red outline → red fill on hover).
+
+### Fixed
+
+- **Gapless playback — manual skip** *(PR [#119](https://github.com/Psychotoxical/psysonic/pull/119) by [@cucadmuh](https://github.com/cucadmuh))*: When the next track had already been gapless-pre-chained into the Sink, a manual skip would not interrupt it — the pre-chained track continued playing at full volume from the old Sink after the fade-out. The chain is now matched by stream identity so user-initiated playback always takes precedence.
+- **Radio / Artist cover cache**: `invalidateCoverArt` is now called after every cover upload and delete, so the old image is evicted from the local cache immediately.
+- **Queue auto-scroll**: The active track now scrolls reliably into view; eliminated unnecessary component re-renders caused by unstable selector references.
+- **macOS TLS** *(PR [#114](https://github.com/Psychotoxical/psysonic/pull/114) by [@nisrael](https://github.com/nisrael))*: Switched `reqwest` from `native-tls` (macOS Security framework) to `rustls-tls` (statically linked). The native backend was returning *bad protocol version* when connecting to HTTPS music servers, silently preventing playback.
+
+### i18n
+
+- **Russian translation improvements** *(PR [#120](https://github.com/Psychotoxical/psysonic/pull/120) by [@kilyabin](https://github.com/kilyabin))*: Extensive phrasing refinements across the entire Russian locale.
+- New keys (`fsLyricsToggle`, embedded lyrics settings) added to all 7 languages (EN, DE, FR, NL, ZH, NB, RU).
+
+---
+
+## [1.34.0] - 2026-04-06
+
+### Added
+
+- **Mobile UI — Early Preview** ⚠️ — After multiple requests from the community, an initial mobile layout is shipping in this release. **This is a very early work-in-progress** — expect rough edges, missing features, and layouts that still need a lot of polish. Feedback is very welcome! Join the [Discord](https://discord.gg/ckVPGPMS) to share your thoughts.
+  - Sidebar and queue panel are hidden on mobile; a sticky **Bottom Navigation Bar** replaces them with quick access to Mainstage, Albums, Now Playing, and Search.
+  - **Mobile Player View** (`/now-playing`) — Full-screen ambient player with dynamic album-art-based background color, large cover art, track metadata line, and playback controls.
+  - **Mobile Search Overlay** — Full-screen search with recent search history, category chips (Albums, Artists, Genres), and grouped results.
+  - **Mobile Album Header** — Compact two-row icon button layout (Play + Queue primary, Favorite + Bio + Download + Offline secondary).
+  - **Mobile Tracklist** — Simplified track rows; disc headers preserved for multi-disc albums.
+  - **Mobile Hero / Carousel** — Blurred-background-only layout with circular Play + Queue buttons.
+- **Russian 2 translation** *(PR [#107](https://github.com/Psychotoxical/psysonic/pull/107) by [@kilyabin](https://github.com/kilyabin))*: A second Russian translation alongside the existing one from [@cucadmuh](https://github.com/cucadmuh) *(PR [#106](https://github.com/Psychotoxical/psysonic/pull/106))*. Both are selectable in Settings → Appearance as **Russian** and **Russian 2**. Since the maintainer neither speaks nor reads Russian, **community feedback is essential here** — please vote on the [Discord](https://discord.gg/ckVPGPMS) or via GitHub which translation feels more natural so we can retire the weaker one in a future release.
+- **Clickable Mainstage section headers** — "Zuletzt hinzugefügt", "Entdecken", "Künstler entdecken", and "Persönliche Favoriten" now navigate to their respective pages on click, with a `ChevronRight` indicator and accent-color hover effect.
+
+### Fixed
+
+- **macOS network playback** *(Issue [#108](https://github.com/Psychotoxical/psysonic/issues/108))*: Added `com.apple.security.network.client` to `Entitlements.plist` and disabled the app sandbox for unsigned/ad-hoc builds. Without this, macOS silently blocked outbound TCP connections from the Rust audio engine, causing the player to skip through every track without playing anything.
+- **Auto-updater** *(under observation)*: Fixed an incorrect signature in the auto-generated `latest.json` — the CI was writing the public key as the signature value. The updater now receives a correctly signed manifest. **Note:** Due to OS-level restrictions on macOS (Gatekeeper) and Windows (SmartScreen) for unsigned apps, it is not yet certain whether the in-app updater will reliably work on these platforms. Manual installation from the Releases page remains the safe fallback.
+
+### Changed
+
+- All new i18n keys added to all 8 languages (EN, DE, FR, NL, ZH, NB, RU, RU2).
+
+## [1.33.0] - 2026-04-06
+
+### Added
+
+- **Norwegian (Bokmål) translation** *(PR [#101](https://github.com/Psychotoxical/psysonic/pull/101) by [@zz5zz](https://github.com/zz5zz))*: Psysonic is now fully translated into Norwegian Bokmål — selectable in Settings → Appearance.
+- **Configurable next-track preload** *(Issue [#102](https://github.com/Psychotoxical/psysonic/issues/102))*: A new setting in Settings → Playback controls when Psysonic starts buffering the next track. Three modes available:
+  - **Balanced** (default) — begins buffering 30 s before the end of the current track (previous behaviour).
+  - **Early** — begins buffering after just 5 s of playback, maximising reliability on slow connections.
+  - **Custom** — set the exact threshold (5 – 120 s before the end) via a slider.
+- **Tray icon visibility toggle**: A new toggle in Settings → App Behavior lets you show or hide the system tray icon. When disabled, the icon is fully removed from the notification area / menu bar.
+
+### Changed
+
+- **Fullscreen Player — complete redesign**: The Ambient Stage has been rebuilt from the ground up.
+  - **Animated mesh background**: A GPU-only animated dark gradient mesh replaces the static blurred cover art background — smooth, performant, no layout repaints.
+  - **Artist portrait**: The right half of the screen now shows the artist's image (loaded from the server), crossfading smoothly on every track change. Falls back to the album cover if no artist image is available.
+  - **Bottom seekbar**: The seekbar is now pinned to the very bottom edge, spanning the full width, with elapsed and remaining timestamps above it.
+  - **Heart button**: You can now star/unstar the currently playing track directly from the Fullscreen Player without leaving the view.
+  - Removed the marquee-scrolling title in favour of a large, wrapping typographic layout.
+- **Star buttons** — all star/favourite buttons across the app (Player Bar, Album Header, Album Tracklist, Queue Panel) now use the CSS class `.is-starred` instead of inline color overrides, making them trivially themeable.
+
+### Fixed
+
+- **macOS — HTTP audio streams**: Added `NSAppTransportSecurity` / `NSAllowsArbitraryLoads` to `Info.plist`. Without this, App Transport Security silently blocked HTTP radio streams and non-HTTPS Navidrome servers from loading audio in WKWebView on macOS.
+
+---
+
+## [1.32.0] - 2026-04-05 — *The Big Easter Update* 🐣
+
+### Added
+
+- **Custom Offline Storage Directory (#95)**: You can now specify a custom directory for the offline library in Settings → Storage & Downloads. This is perfect for offloading your internal drive to an SD card or external HDD.
+- **Robust Volume Handling**: The app now automatically detects if a configured external storage medium is missing and provides a clear "Volume not found" notification instead of failing silently or attempting to download to a non-existent path.
+- **Internet Radio — full release**: The Radio page is now accessible from the sidebar. Complete UI rewrite to a card-based layout (cover art, name, edit/homepage buttons) consistent with the Playlists look. Covers can be uploaded or removed via a hover menu directly on the card.
+- **Internet Radio — Edit Modal**: A dedicated modal lets you change station name, stream URL, and homepage URL, and upload or remove cover art.
+- **Internet Radio — Radio Browser directory** *(via [radio-browser.info](https://www.radio-browser.info))*: Discover new stations directly inside Psysonic. Top stations by vote are shown as suggestions; a debounced search finds stations by name. Favicon images can be imported as cover art in one click.
+- **Settings — Backup & Restore**: Export all your settings (servers, theme, font, keybindings, EQ preset, sidebar order) to a single JSON file and import them on another machine or after a reinstall. Available in Settings → Storage.
+- **Albums — Year Range Filter**: A From/To year input now appears in the Albums toolbar alongside the existing genre filter. Filtering by year and by genre can be combined; clearing both inputs returns to the default view.
+- **Statistics — Library Insights** *(requested via [#88](https://github.com/Psychotoxical/psysonic/issues/88))*:
+  - **Total Playtime** card: computed in the background by paginating your full album list (up to 5 000 albums). Shows `≥ Xh Ym` if the library is larger.
+  - **Genre Insights**: Top 10 genres ranked by song count with proportional progress bars.
+  - **Format Distribution**: Codec breakdown from a random 500-track sample — shows format name and percentage.
+- **Playlist Detail — Cover Upload**: Change or remove a playlist's cover image via the hover menu that appears on the hero artwork — no external tool needed.
+- **Tracklist columns — Playlists & Favorites** *(work in progress)*: PlaylistDetail and Favorites now support the same resizable, configurable column system introduced in v1.31.0 for Album tracklists. Column widths and visibility are persisted independently per page. The feature is still being refined.
+
+### Changed
+
+- **Crossfade — fine-grained control**: The crossfade duration slider now ranges from 0.1 s to 10 s in 0.1 s steps (previously 1 s minimum, 0.5 s steps). The current value is shown with one decimal place.
+- **Settings — Storage tab redesign**: The "Offline Library" section now has a short description and includes Cache settings. The "Downloads" section is now labelled "ZIP Export & Archiving". Both sections have been visually consolidated.
+- **Artists page — Load More button** *(reported via [#90](https://github.com/Psychotoxical/psysonic/issues/90))*: The button is now styled as `btn-primary` with a `ChevronDown` icon and proper spacing. Previously it was an unstyled ghost button with no visual affordance.
+- **Tracklist layout consistency**: The Play-button column is now uniformly 60 px and the title column uses `minmax(150px, 1fr)` across all list views — Search Results, Artist Detail, Random Mix, and Advanced Search now match the Album tracklist layout.
+- **Internet Radio — HTML5 playback**: Radio now streams via the browser's native `<audio>` element instead of a custom Rust pipeline. This improves compatibility with AAC/MP3/HLS streams.
+- **AppUpdater — error visibility** *(experimental, still in progress)*: Update failures are now shown inside the update card rather than silently logged. Auto-update remains experimental — a direct GitHub Releases link is always shown as a fallback.
+- **Queue panel — radio drag**: Dragging a radio station card onto the queue is now silently rejected instead of causing an error.
+
+### Fixed
+
+- **PlayerBar stuck on Radio info**: Switching from an Internet Radio station to a regular track no longer leaves the station name and cover in the player bar. `playTrack` now clears `currentRadio` state and stops the audio element immediately.
+- **Radio favourite icon**: The heart icon is now correctly used for favourite radio stations on both the Internet Radio page and the Favourites page. It was incorrectly showing a star.
+- **Offline track deletion — orphaned directories**: Deleting a cached track now removes empty parent directories up to the configured base directory. Uses `std::fs::remove_dir` (safe — only removes empty directories) to avoid accidental data loss.
+
+---
+
+## [1.31.0] - 2026-04-04
+
+> **Note:** This is likely the last update for the coming week — taking a short break. See you on the other side. ☀️
+
+### Added
+
+- **AutoEQ — 10-Band Parametric Equalizer**: Full parametric EQ with 10 adjustable bands, bypass toggle, and pre-gain control. AutoEQ presets are loaded directly from the AutoEQ GitHub repository — search for your headphone model and apply a community-measured correction curve with one click.
+- **Internet Radio — infrastructure** *(work in progress, not yet released)*: The full backend for Internet Radio playback is in place — a dedicated Rust `RadioBuffer` streaming pipeline in the audio engine, Subsonic API integration (`getInternetRadioStations`, create/update/delete), and a `playRadio` action in the player store. The UI page exists but the feature is **not yet accessible** from the sidebar — it will be enabled once the experience is polished.
+- **Tracklist columns — resizable & configurable** *(experimental)*: Album tracklist columns can now be resized by dragging the dividers between header cells, similar to a spreadsheet. A column visibility picker (chevron button at the top right) lets you show or hide individual columns. The `#` column is fixed-width. Column widths and visibility are persisted in localStorage. The feature works but is still being refined.
+- **Genre column in album tracklist**: Albums that have genre tags per track now show a Genre column in the tracklist.
+- **Sidebar auto-migration**: New sidebar items (e.g. Internet Radio) are automatically appended to existing persisted sidebar configurations on first launch — no more missing entries after updates.
+
+### Changed
+
+- **Discord Rich Presence**: Activity type is now `Listening` instead of the default `Playing`. The artist field no longer has the "by " prefix — Discord's layout makes the context clear without it. Album name is shown as a tooltip on the cover icon.
+- **Clickable artist names everywhere**: Artist names in Album Cards, Favorites, Random Mix, Playlist Detail, and Artist Detail tracklists are now clickable links that navigate to the artist page.
+- **Duration format supports hours**: Tracks and albums longer than 60 minutes are now displayed as `H:MM:SS` instead of overflowing minutes (e.g. `75:03` → `1:15:03`).
+- **Format column**: Codec label no longer includes the "kbps" suffix or the `·` separator — cleaner and fits the narrower column better (e.g. `FLAC 1411` instead of `FLAC · 1411 kbps`).
+- **Now Playing sidebar link**: No longer permanently styled as an active menu item. It now only shows the accent background when you are actually on the Now Playing page; at all other times it is distinguished only by its accent text colour.
+- **Paused-state indicator in tracklist**: When the currently active track is paused, a dimmed play icon is shown in the `#` column instead of a blank space — making it clear which track is loaded even when playback is stopped.
+- **Text selection disabled**: Text can no longer be accidentally selected anywhere in the player by click-dragging or pressing Ctrl+A. Standard input fields are unaffected.
+- **Settings — button styles**: "Test connection", "Add server", and "Pick download folder" buttons are now `btn-surface` (with a subtle border) instead of the borderless `btn-ghost` — clearer affordance.
+- **Settings — Behavior section icon**: Replaced the generic `Sliders` icon with `AppWindow` for the Behavior section header.
+- **`btn-surface` border**: The surface button variant now has a 1 px border that brightens on hover — consistent with the card and input visual language.
+- **Queue panel minimum width**: Increased from 250 px to 310 px to prevent layout overflow when the codec/bitrate overlay is visible.
+- **Server compatibility hint**: A short note below the Servers section header in Settings clarifies which Subsonic-compatible servers are supported.
+
+### Fixed
+
+- **Tracklist `#` column header alignment**: The "Select all" checkbox and the `#` symbol in the header now use the same internal layout as the row cells — ensuring alignment with individual checkboxes and track numbers at all window sizes.
+- **Column resize dividers**: The visible 2 px divider line is now placed in the gap between columns rather than inside the cell, so header labels appear visually centred between their dividers.
+- **Internet Radio sidebar link hidden**: The navigation entry is temporarily removed until the feature is ready for release. The underlying code remains in place and will be re-enabled without any migration required.
+
+---
+
+## [1.30.0] - 2026-04-03
+
+### Added
+
+- **Bulk offline download — Playlists & Artist discographies** *(requested by [@Apollosport](https://github.com/Apollosport), [#54](https://github.com/Psychotoxical/psysonic/issues/54))*: Download an entire playlist or a full artist discography for offline use in one click. Progress is tracked per album on the Artist page ("Caching… 2/5 albums").
+- **Offline Library filter tabs**: The Offline Library now has four filter tabs — All, Albums, Playlists, and Discographies. The Discographies tab groups albums under their respective artist with section headings.
+- **Discord Rich Presence** *(requested by [@Bewenben](https://github.com/Bewenben), [#49](https://github.com/Psychotoxical/psysonic/issues/49))* (opt-in): Psysonic can now update your Discord status with the currently playing track, artist, and a live elapsed timer. Toggle in Settings → General → "Discord Rich Presence".
+- **Artist images on Artists page** *(reported by [@Apollosport](https://github.com/Apollosport), [#53](https://github.com/Psychotoxical/psysonic/issues/53))* (opt-in): Artist avatars on the Artists overview can now show the actual artist image from the server instead of the coloured initial. Toggle in Settings → General → "Show artist images". Off by default to preserve performance on large libraries.
+- **Image lazy loading**: Cover art and artist images across all pages now load lazily via `IntersectionObserver` (300 px pre-fetch margin), significantly reducing initial page render time on large libraries.
+
+### Fixed
+
+- **Crossfade triggers on manual track skip** *(reported by [@netherguy4](https://github.com/netherguy4), [#35](https://github.com/Psychotoxical/psysonic/issues/35))*: Manually clicking Next/Prev or selecting a track from the queue no longer triggers the crossfade transition. Crossfade now only fires on natural track end.
+- **Playlist offline cache showing individual album cards**: Caching a playlist offline previously created one card per album group in the Offline Library. The playlist is now stored as a single cohesive entry.
+- **Image cache abort handling**: Aborted image fetches no longer prevented the cached result from being written to IndexedDB, causing covers to reload on every page visit.
+
+### Changed
+
+- **Queue tech strip**: Removed genre from the codec/bitrate overlay strip in the Queue panel — genre strings frequently caused layout overflow.
+- **"Save discography offline" label**: The Artist page offline button now reads "Save discography offline" instead of "Download discography" to avoid confusion with a ZIP export.
+- **Update toast (Win/Mac)**: The update notification now includes a disclaimer that auto-update is still in development, and always shows a direct GitHub Releases download link alongside the install button as a fallback.
+- **Facebook theme overhaul**: Improved grey text contrast, opaque album chip and back button, readable Queue/Lyrics tab labels.
+
+---
+
+## [1.29.0] - 2026-04-02
+
+### Added
+
+- **Radio: instant start + background enrichment** *(requested by [@netherguy4](https://github.com/netherguy4))*: Artist Radio now starts immediately from fast local `getTopSongs` results. `getSimilarSongs2` (Last.fm-dependent, slow) continues in the background and silently enriches the queue once it resolves — no waiting before the first song.
+- **OGG/Vorbis playback** *(contributed by [@JulianNymark](https://github.com/JulianNymark), [PR #42](https://github.com/Psychotoxical/psysonic/pull/42))*: Added `symphonia-format-ogg` — `.ogg` files now play natively without server-side transcoding.
+- **Click-to-seek in synced lyrics** *(contributed by [@nisarg-78](https://github.com/nisarg-78), [PR #38](https://github.com/Psychotoxical/psysonic/pull/38))*: Clicking any line in the synced lyrics pane seeks directly to that timestamp.
+- **Volume scroll wheel** *(contributed by [@nisarg-78](https://github.com/nisarg-78), [PR #38](https://github.com/Psychotoxical/psysonic/pull/38))*: Scrolling the mouse wheel over the volume slider adjusts volume in ±5 % steps.
+- **Lyrics visual states** *(contributed by [@nisarg-78](https://github.com/nisarg-78), [PR #38](https://github.com/Psychotoxical/psysonic/pull/38))*: Synced lyrics lines now show three distinct visual states — active (highlighted), completed (muted), upcoming (neutral).
+- **Themed audio error toasts** *(contributed by [@JulianNymark](https://github.com/JulianNymark), [PR #43](https://github.com/Psychotoxical/psysonic/pull/43) / [PR #44](https://github.com/Psychotoxical/psysonic/pull/44))*: Unsupported formats and decode failures are now surfaced as themed in-app toast notifications with human-readable messages instead of silent failures.
+
+### Fixed
+
+- **Auto-updater endless loop on macOS / Windows**: The single-instance plugin was killing the relaunching process before it could start. Hopefully fixed by exiting the old process first (releasing the lock) and spawning the new process via a shell-based delayed restart.
+- **Radio queue stacking**: Clicking "Start Radio" multiple times no longer appends unlimited duplicate batches — each click replaces the pending Radio section cleanly.
+- **Start Radio keeps current song playing**: Triggering Radio while a song is playing no longer stops and restarts the current track.
+- **Radio proactive loading with songs missing `artistId`**: `getSimilarSongs2` results frequently lack `artistId`. A `currentRadioArtistId` module variable now persists the original artist ID as fallback, so proactive loading always fires correctly.
+- **Seek audio glitch after lyrics click**: Any seek ≥ 100 ms into a track no longer causes a brief fade-from-zero. `EqualPowerFadeIn` now only resets to zero-gain for seeks to the track start.
+
+### Changed
+
+- **Infinite Queue: 5 tracks at a time** (was 25): Proactive loading fetches 5 tracks when ≤ 2 remain, keeping the queue lean without interruption.
+- **Queue section order is now explicit**: Manual tracks → Radio (with `— Radio —` separator) → Infinite Queue auto-added tracks (with `— Auto —` separator). Manually enqueued songs always appear before auto-managed sections.
+
+### Contributors
+
+Thanks to [@nisarg-78](https://github.com/nisarg-78) and [@JulianNymark](https://github.com/JulianNymark) for their first contributions in this release.
+Special thanks to [@netherguy4](https://github.com/netherguy4) for continued feature ideas and feedback.
+
+---
+
+## [1.28.0] - 2026-04-02
+
+### Added
+
+- **Infinite Queue** *(requested by [@netherguy4](https://github.com/netherguy4))*: When the queue runs out with Repeat off, Psysonic automatically appends 25 random tracks (optionally filtered by the last-played track's genre) so playback never stops. Toggle in Settings → Audio → "Infinite Queue". Auto-added tracks appear below a divider in the Queue panel.
+- **Start Radio plays immediately** *(requested by [@netherguy4](https://github.com/netherguy4))*: "Start Radio" from the song/queue context menu now starts the seed track instantly while similar and top tracks load in the background — no waiting for the fetch to complete before music plays.
+
+### Fixed
+
+- **Single-click to play everywhere** *(reported by [@netherguy4](https://github.com/netherguy4))*: Song rows in Album Detail, Playlist Detail, Artist Detail (Top Tracks), Favorites, and Random Mix previously required a double-click. All rows now play on a single click. The track-number cell and the full row are both click targets; buttons and links inside the row still work independently.
+- **Artist page Play All / Shuffle used Top Tracks only** *(reported by [@smirnoffjr](https://github.com/smirnoffjr))*: "Play All" and "Shuffle" on the Artist detail page only sent the loaded top songs to the queue, not the full discography. Now fetches all albums in parallel and plays songs in chronological album order with correct track-number ordering within each album. Buttons show a spinner while albums are loading.
+- **Last.fm icon clipped in player bar**: The Last.fm logo button in the player bar was cut off on the right side. Fixed by correcting the SVG `viewBox` from `0 0 24 24` to `0 0 26 22` to match the actual path extents.
+- **Playlist empty state UX** *(reported by [@netherguy4](https://github.com/netherguy4))*: Empty playlists (on creation, or after deleting all tracks) now show an "Add your first song" CTA button that opens the search panel directly, rather than a plain text message with no action.
+- **Playlist search rows required "+" button click** *(reported by [@netherguy4](https://github.com/netherguy4))*: Search result rows in the song search panel now add the song on a full-row click — the separate "+" button was redundant and easy to miss.
+- **Large playlist performance**: Playlists with hundreds of songs would freeze during mouse movement. Root cause: `hoveredSongId` state triggered a full React re-render of every row on every `mouseenter`/`mouseleave` event. Fixed by removing the JS hover state and replacing it with a CSS `.track-row:hover .bulk-check` rule. Also memoized `songs.map(songToTrack)` and the `existingIds` set to avoid recomputation per render. Same fix applied to `AlbumTrackList`.
+
+---
+
+## [1.27.4] - 2026-04-02
+
+### Added
+
+- **In-App Auto-Update** *(requested by [@netherguy4](https://github.com/netherguy4))*: Psysonic now checks for new releases automatically on startup (3 s delay). On macOS and Windows a native install-and-relaunch flow is available directly in the app — no browser needed. On Linux, a download link to the GitHub release page is shown instead (AppImage is not built due to WebKitGTK incompatibility with Arch/Fedora). The updater uses Tauri's signed updater plugin with minisign signatures verified against a bundled public key.
+- **Configurable Home Page**: Users can now choose which sections appear on the home page. A new "Home Page" block in Settings → Library lets you toggle each section individually (Featured, Recently Added, Discover, Discover Artists, Recently Played, Personal Favorites, Most Played) with a reset-to-default button. Hidden sections are skipped entirely.
+- **Consistent icon language** *(requested by [@netherguy4](https://github.com/netherguy4))*: Favorites (local star/heart) now use a filled Heart icon everywhere — Player Bar, Album Detail, Artist Detail, Tracklist, Context Menu. Last.fm love always uses the Last.fm logo. Previously the two were mixed up in several places.
+
+### Fixed
+
+- **Radio broken from context menu** *(reported by [@netherguy4](https://github.com/netherguy4))*: "Start Radio" in the track and queue-item context menus had no effect. The handler was passing the artist name as the artist ID to `getSimilarSongs2`, which returned an empty result — so no tracks were queued and no error was shown. Now correctly passes `song.artistId`.
+- **Album Detail hero background not loading**: The blurred album art background in Album Detail only appeared after a track change, never on first visit. Root cause: `buildCoverArtUrl` was called without `useMemo`, generating a new salt on every re-render — causing `useCachedUrl` to cancel and restart its fetch endlessly. Fixed by memoising both the URL and cache key on `album.coverArt`. Same fix applied to Hero and Playlist Detail backgrounds.
+- **CI: auto-update signing pipeline**: Signing keys were not being passed correctly during the build, and macOS `.sig` files were uploaded with a generic name the manifest generator couldn't match. Fixed the post-build signing step to upload arch-specific names (`Psysonic_aarch64.app.tar.gz.sig`, `Psysonic_x64.app.tar.gz.sig`). First release where the in-app updater is fully functional on macOS and Windows.
+- **CI: Windows NSIS upload**: The release workflow was not correctly uploading Windows artifacts. Resolved by letting `tauri-action` handle NSIS bundle detection and upload directly — it only searches for what was actually built, so there is no MSI conflict with `--bundles nsis` builds.
+- **CI: npm + Cargo caching** *(contributed by [@netherguy4](https://github.com/netherguy4))*: Added `actions/cache` for npm and `Swatinem/rust-cache` for Cargo across all build jobs. Warm-cache builds will be significantly faster on subsequent releases.
+- **Linux/AUR build: ring linker error**: Builds on Arch/CachyOS failed with `rust-lld: undefined symbol: ring_core_*` after the Tauri updater was added. Arch's `rust` package bakes `-fuse-ld=lld` into the default rustflags; ring's C/asm objects are incompatible with lld. Fixed via `.cargo/config.toml` — forces `cc` as linker driver with `-fuse-ld=bfd` to override the hardcoded lld flag. Added `clang` to the AUR `makedepends` (required by ring's bindgen step).
+
+---
+
+## [1.26.1] - 2026-04-01
+
+### Fixed
+
+- **Background flickering in Hero, Album Detail and Playlist Detail**: Blurred hero backgrounds were flickering for up to 20 seconds on first visit. Root cause: `useCachedUrl` with the default `fallbackToFetch = true` immediately returned the raw server URL, causing the background to render twice — once with the HTTP URL (triggering a server fetch) and again when the IndexedDB blob was ready. Fixed by passing `fallbackToFetch = false` in all three locations so the background only renders once the blob is cached.
+
+---
+
+## [1.26.0] - 2026-04-01
+
+### Added
+
+- **Favorite button in Player Bar** *(requested by [@halfkey](https://github.com/halfkey))*: A star icon button now sits next to the Last.fm heart in the player bar. Clicking it toggles the favorite/unfavorite state for the currently playing track with an optimistic UI update — no page reload needed. Uses the same `starredOverrides` mechanism as the album tracklist for instant feedback.
+- **Bulk Select for song lists**: Multi-select support in Album tracklist and Playlist detail. A checkbox fades in to the left of the track number on hover. Selecting one or more tracks activates the bulk action bar at the top with two actions: **Add to Playlist** (opens the playlist picker submenu) and **Remove from Playlist** (Playlist detail only). Shift-click selects a range; the header checkbox selects / deselects all. CSS uses `color-mix` for the selection highlight, compatible with all 60 themes.
+- **Song Info modal**: Right-clicking any song and choosing "Song Info" opens a metadata panel fetched live via `getSong`. Displays: title, artist, album, album artist, year, genre, duration, track number; format, bitrate, sample rate, bit depth, channels (Mono / Stereo), file size; file path; and Replay Gain values (track / album gain + peak) when present. Closes with Escape or a click on the backdrop.
+- **Recently Played section on Home page**: A new "Recently Played" album row appears on the Home page between the hero carousel and the Discover section, powered by the `getAlbumList('recent')` endpoint.
+- **"Now Playing" visibility toggle in Settings**: New opt-in toggle in Settings → Behavior ("Show activity in Now Playing"). When disabled (default), `reportNowPlaying` is not called, so no activity is reported to the Navidrome "Now Playing" feed. Useful for users who share a server.
+
+### Fixed
+
+- **Queue cover art not updating**: After a track change the queue panel cover art often stayed on the previous album or took a long time to update. Root cause: `useCachedUrl` and `CachedImage` were not resetting their resolved URL when the `cacheKey` changed. Fixed by resetting `resolved` to `''` before each async cache fetch and basing `CachedImage`'s `loaded` state on `useEffect([cacheKey])` instead of a render-time comparison.
+- **Fullscreen Player background flickering**: The blurred background briefly showed a blank frame when switching tracks because the new image div was added to the DOM before the blob URL was ready. Fixed in `FsBg` by preloading the image via `new Image()` before inserting the layer, and using `useCachedUrl(..., false)` for the crossfade background so the raw URL is never used as a fallback during transitions.
+- **Playlist card delete confirmation not visible**: The confirm state only changed the icon colour, which was barely noticeable over the red button. Replaced with a size expansion (24 px → 30 px), an inset white ring, and a pulsing `delete-confirm-pulse` animation that alternates between two shades of red.
+- **Gruvbox Light Soft — back button and badge**: The album detail back-arrow and album badge were invisible against the warm light background. Added explicit colour overrides for `.album-detail-back` and `.album-detail-badge` in the gruvbox-light-soft theme.
+
+### Changed
+
+- **`buildStreamUrl` signature**: Removed the unused `suffix` parameter. Opus transcoding (`format=flac`) is now handled in `playerStore.playTrack` via `track.suffix` check, keeping the URL builder stateless.
+
+---
+
+## [1.25.1] - 2026-04-01
+
+### Fixed
+
+- **Single-instance enforcement** *(reported by [@netherguy4](https://github.com/netherguy4))*: Re-launching the app while it was already running (including minimized to tray) would spawn a new independent process, leading to playback conflicts and state divergence. Integrated `tauri-plugin-single-instance` — subsequent launches are intercepted, the existing window is shown, unminimized, and focused instead.
+
+---
+
+## [1.25.0] - 2026-04-01
+
+### Added
+
+- **System Tray** *(requested by [@jackbot](https://github.com/jackbot) and [@thecyanide](https://github.com/thecyanide))*: Functional tray icon with context menu — Play / Pause, Previous Track, Next Track, Show / Hide, and Exit Psysonic. Left-clicking the tray icon toggles window visibility. The tray icon is built via `TrayIconBuilder` in Rust so menu events are properly wired.
+- **Minimize to Tray** *(requested by [@jackbot](https://github.com/jackbot) and [@thecyanide](https://github.com/thecyanide))*: New toggle in Settings → Behavior. When enabled, closing the window hides it to the tray instead of exiting. The close button behaviour is intercepted in Rust (`prevent_close` + `window:close-requested` event) and the JS side decides hide vs. exit based on the user setting.
+- **Sidebar Customization** *(requested by [@lighthous3d](https://github.com/lighthous3d))*: New section in Settings → Appearance. All library and system nav items can be shown/hidden via a toggle switch and reordered by dragging the grip handle. Order and visibility are persisted across sessions (`psysonic_sidebar` in localStorage). Fixed items (Now Playing, Settings) are listed as non-configurable below the list.
+- **Playlist cover art**: Playlist cards on the Playlists overview page now display the server-generated cover image (Navidrome's `coverArt` field on the playlist object) via the IndexedDB image cache. Falls back to the ListMusic icon when no cover is available.
+
+### Fixed
+
+- **Cover image flickering**: `buildCoverArtUrl()` generates a new random auth salt on every call, causing `useCachedUrl` to re-trigger on every render and produce a rapid re-fetch loop. Fixed by wrapping all `buildCoverArtUrl` / `coverArtCacheKey` calls in `useMemo` with the cover ID as dependency in `ArtistCardLocal`, `QueuePanel`, `FullscreenPlayer`, `Hero`, and `PlaylistDetail`.
+- **DnD text selection**: Dragging a grip handle in the Sidebar Customizer (and any future `useDragSource` consumer) would select all text on the page during the threshold detection phase. Fixed by calling `e.preventDefault()` in `useDragSource`'s `onMouseDown` handler before the drag threshold is reached.
+- **Sidebar Customization DnD on Linux**: The initial implementation used the HTML5 Drag & Drop API, which always shows a forbidden cursor on WebKitGTK and does not fire drop events reliably. Rewritten to use the existing psy-drag mouse-event system (`useDragSource` / `psy-drop` custom event), consistent with the Queue panel.

+# Privacy Policy
+
+Psysonic is a self-hosted music player. It does not collect telemetry, analytics, or any data on its own. All data stays on your device or travels exclusively between your device and services you explicitly configure.
+
+## Data sent to third-party services
+
+All third-party integrations listed below are **opt-in**. Nothing is sent until you enable the respective feature.
+
+### Your Subsonic / Navidrome server
+Your server URL, username, and password are stored locally in the app's data directory. All playback and library requests go directly to your own server. Psysonic has no access to this data.
+
+### Last.fm
+If you connect a Last.fm account in Settings, Psysonic sends:
+- **Scrobbles** — track title, artist, album, and timestamp when a song reaches 50% playback
+- **Now Playing** — the currently playing track (title, artist, album)
+- **Love / Unlove** — when you mark a track as loved or unloved
+
+All requests go to the [Last.fm API](https://www.last.fm/api). Your Last.fm credentials are stored locally and never leave your device. You can disconnect your account at any time in Settings.
+
+### LRCLIB (Lyrics)
+When lyrics are fetched from LRCLIB, Psysonic sends the track title, artist, album, and duration to [lrclib.net](https://lrclib.net) as a search query. No account is required. This feature can be disabled in Settings → Lyrics.
+
+### NetEase Cloud Music (Lyrics)
+If NetEase is enabled as a lyrics source in Settings → Lyrics, Psysonic sends the track artist and title to the NetEase Cloud Music API (via a Rust-side proxy request) to search for synced lyrics. No account is required. This feature is disabled by default.
+
+### Apple Music / iTunes Search API
+If "Use Apple Music covers for Discord" is enabled in Settings, Psysonic queries the [iTunes Search API](https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/iTuneSearchAPI/) with the current track's artist and album name to find cover art. No Apple account is required. Apple's own privacy policy applies to these requests.
+
+### Discord Rich Presence
+If Discord is running and Rich Presence is not disabled, Psysonic connects to the local Discord client via its IPC socket to display the currently playing track. This data is sent to Discord and subject to [Discord's privacy policy](https://discord.com/privacy). No data is sent if Discord is not installed or not running.
+
+## Data stored locally
+
+The following data is stored exclusively on your device in the app's local storage directory and is never transmitted:
+
+- Server profiles (URL, username, password)
+- Last.fm session key
+- Playback preferences, themes, keybindings, and all other settings
+- Synced device manifests
+
+## No telemetry
+
+Psysonic contains no crash reporting, analytics, usage tracking, or any form of telemetry.
+
+## Open source
+
+Psysonic is fully open source under the [GNU General Public License v3.0](LICENSE). You can verify exactly what data is sent by reading the source code.

+# Shell completion for `psysonic`
+
+Covers global flags (`--help`, `--info`, …), `completions …`, and `--player` commands (`next`, `audio-device …`, `library …`, `mix …`, …). Run `psysonic --help` for the full list.
+
+The same scripts are **embedded in the release binary**: run **`psysonic completions`** for install instructions, or **`psysonic completions bash` / `zsh`** to print the scripts (no repo checkout needed).
+
+## zsh
+
+Copy or symlink `_psysonic` into a directory on your `$fpath`, then reload completion:
+
+```sh
+mkdir -p ~/.zsh/completions
+ln -sf /path/to/psysonic/completions/_psysonic ~/.zsh/completions/_psysonic
+fpath=(~/.zsh/completions $fpath)
+autoload -Uz compinit && compinit
+```
+
+If you use a plugin manager, point its `fpath` at this repo’s `completions/` directory instead.
+
+## bash
+
+Source the script once (e.g. in `~/.bashrc`):
+
+```sh
+source /path/to/psysonic/completions/psysonic.bash
+```
+
+Use this only under **bash** (including macOS’s `/bin/bash` 3.2). **zsh** users should install `_psysonic` instead — do not `source` the `.bash` file in zsh.
+
+## Device names after `audio-device set`
+
+Completion can suggest IDs from `psysonic-cli-audio-devices.json` (same paths the app uses: `$XDG_RUNTIME_DIR` or `$TMPDIR`/`/tmp`). That file appears after you run **`psysonic --player audio-device list`** while the app is running. Optional: install **`jq`** for parsing that JSON in the completion scripts.
+
+## Folder ids after `library set`
+
+Same idea with **`psysonic-cli-library.json`**, produced by **`psysonic --player library list`**. Optional **`jq`** for completion of folder ids plus the literal **`all`**.

+# CPAL - Cross-Platform Audio Library
+
+[![Actions Status](https://github.com/RustAudio/cpal/workflows/cpal/badge.svg)](https://github.com/RustAudio/cpal/actions)
+[![Crates.io](https://img.shields.io/crates/v/cpal.svg)](https://crates.io/crates/cpal) [![docs.rs](https://docs.rs/cpal/badge.svg)](https://docs.rs/cpal/)
+
+Low-level library for audio input and output in pure Rust.
+
+This library currently supports the following:
+
+- Enumerate supported audio hosts.
+- Enumerate all available audio devices.
+- Get the current default input and output devices.
+- Enumerate known supported input and output stream formats for a device.
+- Get the current default input and output stream formats for a device.
+- Build and run input and output PCM streams on a chosen device with a given stream format.
+
+Currently, supported hosts include:
+
+- Linux (via ALSA or JACK)
+- Windows (via WASAPI by default, see ASIO instructions below)
+- macOS (via CoreAudio)
+- iOS (via CoreAudio)
+- Android (via Oboe)
+- Emscripten
+
+Note that on Linux, the ALSA development files are required. These are provided
+as part of the `libasound2-dev` package on Debian and Ubuntu distributions and
+`alsa-lib-devel` on Fedora.
+
+## Compiling for Web Assembly
+
+If you are interested in using CPAL with WASM, please see [this guide](https://github.com/RustAudio/cpal/wiki/Setting-up-a-new-CPAL-WASM-project) in our Wiki which walks through setting up a new project from scratch.
+
+## Feature flags for audio backends
+
+Some audio backends are optional and will only be compiled with a [feature flag](https://doc.rust-lang.org/cargo/reference/features.html).
+
+- JACK (on Linux): `jack`
+- ASIO (on Windows): `asio`
+
+Oboe can either use a shared or static runtime. The static runtime is used by default, but activating the
+`oboe-shared-stdcxx` feature makes it use the shared runtime, which requires `libc++_shared.so` from the Android NDK to
+be present during execution.
+
+## ASIO on Windows
+
+[ASIO](https://en.wikipedia.org/wiki/Audio_Stream_Input/Output) is an audio
+driver protocol by Steinberg. While it is available on multiple operating
+systems, it is most commonly used on Windows to work around limitations of
+WASAPI including access to large numbers of channels and lower-latency audio
+processing.
+
+CPAL allows for using the ASIO SDK as the audio host on Windows instead of
+WASAPI.
+
+### Locating the ASIO SDK
+
+The location of ASIO SDK is exposed to CPAL by setting the `CPAL_ASIO_DIR` environment variable.
+
+The build script will try to find the ASIO SDK by following these steps in order:
+
+1. Check if `CPAL_ASIO_DIR` is set and if so use the path to point to the SDK.
+2. Check if the ASIO SDK is already installed in the temporary directory, if so use that and set the path of `CPAL_ASIO_DIR` to the output of `std::env::temp_dir().join("asio_sdk")`.
+3. If the ASIO SDK is not already installed, download it from <https://www.steinberg.net/asiosdk> and install it in the temporary directory. The path of `CPAL_ASIO_DIR` will be set to the output of `std::env::temp_dir().join("asio_sdk")`.
+
+In an ideal situation you don't need to worry about this step.
+
+### Preparing the build environment
+
+1. `bindgen`, the library used to generate bindings to the C++ SDK, requires
+   clang. **Download and install LLVM** from
+   [here](http://releases.llvm.org/download.html) under the "Pre-Built Binaries"
+   section. The version as of writing this is 17.0.1.
+2. Add the LLVM `bin` directory to a `LIBCLANG_PATH` environment variable. If
+   you installed LLVM to the default directory, this should work in the command
+   prompt:
+   ```
+   setx LIBCLANG_PATH "C:\Program Files\LLVM\bin"
+   ```
+3. If you don't have any ASIO devices or drivers available, you can [**download
+   and install ASIO4ALL**](http://www.asio4all.org/). Be sure to enable the
+   "offline" feature during installation despite what the installer says about
+   it being useless.
+4. Our build script assumes that Microsoft Visual Studio is installed if the host OS for compilation is Windows. The script will try to find `vcvarsall.bat`
+   and execute it with the right host and target machine architecture regardless of the Microsoft Visual Studio version.
+   If there are any errors encountered in this process which is unlikely,
+   you may find the `vcvarsall.bat` manually and execute it with your machine architecture as an argument.
+   The script will detect this and skip the step.
+
+   A manually executed command example for 64 bit machines:
+
+   ```
+   "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
+   ```
+
+   For more information please refer to the documentation of [`vcvarsall.bat``](https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=msvc-160#vcvarsall-syntax).
+
+5. Select the ASIO host at the start of our program with the following code:
+
+   ```rust
+   let host;
+   #[cfg(target_os = "windows")]
+   {
+      host = cpal::host_from_id(cpal::HostId::Asio).expect("failed to initialise ASIO host");
+   }
+   ```
+
+   If you run into compilations errors produced by `asio-sys` or `bindgen`, make
+   sure that `CPAL_ASIO_DIR` is set correctly and try `cargo clean`.
+
+6. Make sure to enable the `asio` feature when building CPAL:
+
+   ```
+   cargo build --features "asio"
+   ```
+
+   or if you are using CPAL as a dependency in a downstream project, enable the
+   feature like this:
+
+   ```toml
+   cpal = { version = "*", features = ["asio"] }
+   ```
+
+_Updated as of ASIO version 2.3.3._
+
+### Cross compilation
+
+When Windows is the host and the target OS, the build script of `asio-sys` supports all cross compilation targets
+which are supported by the MSVC compiler. An exhaustive list of combinations could be found [here](https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=msvc-160#vcvarsall-syntax) with the addition of undocumented `arm64`, `arm64_x86`, `arm64_amd64` and `arm64_arm` targets. (5.11.2023)
+
+It is also possible to compile Windows applications with ASIO support on Linux and macOS.
+
+For both platforms the common way to do this is to use the [MinGW-w64](https://www.mingw-w64.org/) toolchain.
+
+Make sure that you have included the `MinGW-w64` include directory in your `CPLUS_INCLUDE_PATH` environment variable.
+Make sure that LLVM is installed and include directory is also included in your `CPLUS_INCLUDE_PATH` environment variable.
+
+Example for macOS for the target of `x86_64-pc-windows-gnu` where `mingw-w64` is installed via brew:
+
+```
+export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:/opt/homebrew/Cellar/mingw-w64/11.0.1/toolchain-x86_64/x86_64-w64-mingw32/include"
+```

+//! # How to use cpal
+//!
+//! Here are some concepts cpal exposes:
+//!
+//! - A [`Host`] provides access to the available audio devices on the system.
+//!   Some platforms have more than one host available, but every platform supported by CPAL has at
+//!   least one [default_host] that is guaranteed to be available.
+//! - A [`Device`] is an audio device that may have any number of input and
+//!   output streams.
+//! - A [`Stream`] is an open flow of audio data. Input streams allow you to
+//!   receive audio data, output streams allow you to play audio data. You must choose which
+//!   [Device] will run your stream before you can create one. Often, a default device can be
+//!   retrieved via the [Host].
+//!
+//! The first step is to initialise the [`Host`]:
+//!
+//! ```
+//! use cpal::traits::HostTrait;
+//! let host = cpal::default_host();
+//! ```
+//!
+//! Then choose an available [`Device`]. The easiest way is to use the default input or output
+//! `Device` via the [`default_input_device()`] or [`default_output_device()`] methods on `host`.
+//!
+//! Alternatively, you can enumerate all the available devices with the [`devices()`] method.
+//! Beware that the `default_*_device()` functions return an `Option<Device>` in case no device
+//! is available for that stream type on the system.
+//!
+//! ```no_run
+//! # use cpal::traits::HostTrait;
+//! # let host = cpal::default_host();
+//! let device = host.default_output_device().expect("no output device available");
+//! ```
+//!
+//! Before we can create a stream, we must decide what the configuration of the audio stream is
+//! going to be.    
+//! You can query all the supported configurations with the
+//! [`supported_input_configs()`] and [`supported_output_configs()`] methods.
+//! These produce a list of [`SupportedStreamConfigRange`] structs which can later be turned into
+//! actual [`SupportedStreamConfig`] structs.
+//!
+//! If you don't want to query the list of configs,
+//! you can also build your own [`StreamConfig`] manually, but doing so could lead to an error when
+//! building the stream if the config is not supported by the device.
+//!
+//! > **Note**: the `supported_input/output_configs()` methods
+//! > could return an error for example if the device has been disconnected.
+//!
+//! ```no_run
+//! use cpal::traits::{DeviceTrait, HostTrait};
+//! # let host = cpal::default_host();
+//! # let device = host.default_output_device().unwrap();
+//! let mut supported_configs_range = device.supported_output_configs()
+//!     .expect("error while querying configs");
+//! let supported_config = supported_configs_range.next()
+//!     .expect("no supported config?!")
+//!     .with_max_sample_rate();
+//! ```
+//!
+//! Now that we have everything for the stream, we are ready to create it from our selected device:
+//!
+//! ```no_run
+//! use cpal::Data;
+//! use cpal::traits::{DeviceTrait, HostTrait, StreamTrait};

+//! While the stream is running, the selected audio device will periodically call the data callback

+//! `&mut Data`](Data) depending on whether the stream is an input stream or output stream respectively.
+//!
+//! > **Note**: Creating and running a stream will *not* block the thread. On modern platforms, the

+//! Some devices support pausing the audio stream. This can be useful for saving energy in moments
+//! of silence.

+///
+/// For example, WASAPI is the standard audio host API that ships with the Windows operating
+/// system. However, due to historical limitations with respect to performance and flexibility,
+/// Steinberg created the ASIO API providing better audio device support for pro audio and
+/// low-latency applications. As a result, it is common for some devices and device capabilities to
+/// only be available via ASIO, while others are only available via WASAPI.
+///
+/// Another great example is the Linux platform. While the ALSA host API is the lowest-level API
+/// available to almost all distributions of Linux, its flexibility is limited as it requires that
+/// each process have exclusive access to the devices with which they establish streams. PulseAudio
+/// is another popular host API that aims to solve this issue by providing user-space mixing,
+/// however it has its own limitations w.r.t. low-latency and high-performance audio applications.
+/// JACK is yet another host API that is more suitable to pro-audio applications, however it is
