 * The **Settings → Integrations → Discord → Cover art source → Server** option sent your server's cover URL to Discord, which republishes external image links, so anyone viewing your Rich Presence could read your username and login token. That option has been removed — cover art now comes only from **None** (app icon) or **Apple Music**, neither of which carries your credentials. Any saved **Server** setting is switched to **None**.

+* Renaming an artist on the server no longer leaves a stale entry in the local Artists list that opened to "Artist not found" — a sync now prunes artist rows the latest server listing no longer confirms that also have no remaining tracks. Cleanup runs on both full and delta syncs (only after a confirmed artist listing, so a transient empty response can't drop valid entries), plus a one-time pass at startup that clears ghosts already accumulated in existing libraries.
+* Newly added or renamed entries now show up right after a resync instead of only after an app restart: the Artists and Albums pages refresh their cached catalog when a library sync finishes.
