+# Changelog
+
+## 2026-10-26
+
+- Project created.
+
+2026-10-28 iOS: stemd queue state (STEMMING/QUEUED/FAILED tags, Stem Now state, CarPlay, stemd line in Stem Server settings). Plex sign-in via plex.tv adds every server and all music libraries.
+2026-10-28 iOS: media fetch errors (HTTP 500/404) now include the Plex host, port and path.
+2026-10-28 iOS: Plex refresh keeps each server's library selection (new servers still get all libraries). Music Servers list moved to its own page under Plex Account.
+2026-10-28 iOS: CarPlay Downloads opens onto Playlists/Albums/Artists/Songs, limited to downloaded music.
+2026-10-28 iOS: stem playlists refresh their track metadata from Plex on each library load. Playlist covers can be changed from the playlist menu.
+2026-10-28 iOS: Downloads 3-dots menu gets View Queue (waiting, downloading, failed, done).
+2026-10-28 iOS: Library screen can be reordered (Reorder button). Library Radio and Random Album Radio shuffle the whole library.
+2026-10-28 iOS: Random Album Radio plays whole albums in track order, albums in random order across the library, loading the next album as one finishes.
+2026-10-28 iOS: Library screen Reorder now covers whole sections (Recent Plays, Recently Added, On This Day, Stations, Browse) and each can be shown or hidden
+2026-10-28 iOS: Removed drag reorder from the Tab Bar settings page
+2026-10-28 iOS: CarPlay Downloads Playlists, Albums and Artists load from local downloads, work offline
+2026-10-28 iOS: Stem playlist metadata refresh matches by key, file, then title/artist with a search fallback, and also runs when the app returns to the foreground
+2026-10-29 server: stemd prunes stems whose source song is gone (orphans). PRUNE, PRUNE_CHANGED, PRUNE_MAX env. server/prune.py is a dry-run CLI.
+2026-10-31 iOS: version is now 1.0 RC 1 (build 21). Bundle version 1.0, label in StemifyVersionLabel, IPA stemify-1.0-rc1.ipa, tag ios-v1.0-rc1.
+2026-10-31 iOS: battery and heat. Waveform redraws 4/s instead of 120, meters and playing bars capped at 30 fps. Engine sleeps until its buffer is half drained (120 ms foreground, 600 ms with no screen), 2 s idle while paused. Decoders wake on a low-water mark and run at userInitiated. stemd polling stops in the background unless CarPlay is connected. Widget reloads settle for 0.6 s.
+2026-10-31 web: player redraws the waveform only when the playhead moves a bar (200 ms tick instead of rAF), caches the envelope, and stops polling while the tab is hidden.
+2026-11-06 iOS: version is now 1.0 RC 2 (build 22). IPA stemify-1.0-rc2.ipa, tag ios-v1.0-rc2.
+2026-11-06 iOS: plain Plex songs play when Remote Access has an upload cap. Streams now ask Plex for a playback decision first and fetch the part with that session, like Plexamp, instead of a bare part URL that Plex rejected with a 500.
+2026-11-06 iOS: shuffle buttons (Songs, Library Radio) play server-side random batches of 100 and top up as the queue runs low, instead of loading the whole library and timing out.
+2026-11-06 iOS: Random Album Radio works like Plexamp. It shuffles the album list once, keeps about 8 albums queued ahead in that order, plays each album in track order, and tops up when 3 are left. The station survives a restart.
+2026-11-06 iOS: Recently Added has See All, a full scrolling list sorted by date added. Tapping a song on the Library page plays from it through the last 500 added songs.
+2026-11-06 iOS: stem playlist covers can come from Photos (Change Cover > Choose from Photos). Stored on the phone, 1200 px JPEG.
+2026-11-06 iOS: Update Download on downloaded playlists, albums, artists and stem playlists (their menus and the Downloads tab), plus Update All Downloads. Pulls the current song list, downloads new songs, drops removed ones, retries failed ones. Downloads still sync on their own when the app opens.
+2026-11-06 iOS: crossfade, Off or 1-12 s in Settings > Listening. Equal-power fade, Sweet Fades skips it between songs of the same album. Seeking during a fade finishes it.
+2026-11-09 iOS: iPhone Duo unfolded uses both sides of the hinge: library on one side, Now Playing docked on the other (no mini player while split). Folded and other iPhones unchanged. 1.0 RC 3 (build 23).
+2026-11-09 iOS: Duo split now engages with the phone lying flat (hinge region reports inactive then), with a screen-size fallback if no region is reported. 1.0 RC 4 (build 24).
+2026-11-09 iOS: dev builds (`ios/scripts/build-remote.sh dev`): bundle id org.cdnutter.stemify-dev, "Stemify Dev", own App Group, into ios/build/dev. Internal tests only, never on Gitea or Sideload.
+2026-11-09 iOS: Duo unfolded redesign. Tabs move to a rail on the right edge by the status bar, Now Playing fills the screen with stems and queue on the left and the player on the right, picking a tab swaps the left pane, Swap flips the sides (remembered). Folded screen unchanged.
+2026-11-09 iOS: build-remote.sh now builds dev + prov by default; public only with `public`.
