v0.10.0 - Stable Release

Stable build of CAMusic for Android.

Install

1. Download camusic-0.10.0.apk below (Android 12 / API 31+).
2. Allow install from unknown sources, then open it. Installs over 0.9.x (versionCode 45) — same signing key, so your servers, credentials and downloads survive.

The v0.10 plan, built from a full codebase audit rather than assumed from
docs. Four new Light Sync layers, four driving-mode features, and a batch
of smaller additions — each independently gated and off by default unless
noted.

Four creative Light Sync layers

Off by default, additive on top of the existing engine:

• Music DNA — a per-track visual fingerprint from tempo, detected key,
  intensity and song structure.
• Emotional Arc — colour temperature follows the song's live
  structure rather than staying fixed.
• Phantom Stage — instrument groups pinned to fixed positions in the
  room, as if the band were standing there.
• Phone Conductor — the phone's own motion becomes a lighting
  control.

All four stay inside the existing brightness ceiling and effect-rate
limiter.

Driving mode gets four more features

• Speed limit alert: a single gentle tone once you've been over the
  limit (plus tolerance) for 5 straight readings, repeating at most every
  30 seconds.
• Speed-adaptive volume, sharing the same GPS subscription as the
  alert.
• Auto-pause on a phone call, opt-in, that deliberately never
  auto-resumes on hangup — a notification offers the tap back instead,
  since you may not have been mid-song when the call started.
• A shuffle toggle in the driving bar.

Every driving addition is off by default and asks for its own permission
(location, phone state) only when turned on.

Also new

• A listening-statistics screen (Settings → About → Listening stats):
  total time, top artists, most-played track, and format/server
  breakdowns over the last 7 days.
• Encrypted settings backup and restore — export every setting,
  including saved servers, to a password-encrypted file.
• Long-press the Now Playing cover for quick actions: go to album, go
  to artist, share.
• Swipe a track row — right to queue it, left to play it next.
• Beat-aligned track fades, timing the existing sequential
  fade-out/fade-in to land on a beat rather than an arbitrary offset.
• A notification when a USB DAC connects, pointing at the existing
  output picker in Settings → Audio.
• Jellyfin's scrobble position no longer drifts on pause — it was
  derived from wall-clock elapsed time, so a paused track could report
  itself finished twice over.

Under the hood

The dead, never-selected SendspinAudioEngine (1,035 lines) is gone; the
ExoPlayer path has been the only Sendspin engine on real hardware since
0.9.0.

The experimental native Oboe output path is unchanged and still off by
default; a further fix and the original investigation stay open on
separate branches for the next release.
