v1.4.0: sequential enrichment, GPU auto-detection, repo cleanup

- Run audio analysis and vibe embedding phases sequentially to prevent
  resource contention (CPU/memory) from concurrent analyzers
- Auto-detect GPU availability in both audio analyzers (CUDA/ROCm)
- Fix false lite mode detection on startup by checking analyzer scripts
  on disk before falling back to heartbeat/DB checks
- Fix Dockerfile NEXT_PUBLIC_BACKEND_URL and frontend rewrite proxy
- Route enrichment failures through notification system instead of
  persistent error banner
- Remove playback error banner from player components
- Reduce enrichment cycle interval from 6h to 2h
- Comprehensive repo cleanup: remove 127 decorative comment dividers
  across 17 files, clean verbose comments, harden .gitignore, remove
  tracked docs from git

+## [1.4.0] - 2026-02-05
+
+### Performance
+
+- **Sequential audio/vibe enrichment:** Vibe phase skips when audio analysis is still running, preventing concurrent CPU-intensive Python analyzers from competing for resources
+- **Faster enrichment cycles:** Reduced cycle interval from 30s to 5s; the rate limiter already handles API throttling, making the extra delay redundant
+- **GPU auto-detection (CLAP):** PyTorch-based CLAP vibe embeddings auto-detect and use GPU when available, falling back to CPU
+- **GPU auto-detection (Essentia):** TensorFlow-based audio analysis detects GPU with memory growth enabled, with device logging on startup
+
+### Changed
+
+- **Enrichment orchestration simplified:** Replaced 4 phase functions with duplicated stop/pause handling with a generic `runPhase()` executor and `shouldHaltCycle()` helper
+
+### Fixed
+
+- **Docker frontend routing:** Fixed `NEXT_PUBLIC_BACKEND_URL` build-time env var in Dockerfile so the frontend correctly proxies API requests to the backend
+- **Next.js rewrite proxy:** Updated rewrite config to use `NEXT_PUBLIC_BACKEND_URL` for consistent build-time/runtime behavior
+- **False lite mode on startup:** Feature detection now checks for analyzer scripts on disk, preventing false "lite mode" display before analyzers send their first heartbeat
+- **Removed playback error banner:** Removed the red error bar from all player components (FullPlayer, MiniPlayer, OverlayPlayer) that displayed raw Howler.js error codes
+- **Enrichment failure notifications:** Replaced aggressive per-cycle error banner with a single notification through the notification system when enrichment completes with failures
+
+## [1.3.9] - 2026-02-04
+
+### Fixed
+
+- **Audio analysis cleanup:** Fixed race condition in audio analysis cleanup that could reset tracks still being processed
+
+## [1.3.8] - 2026-02-03
+
+### Fixed
+
+- **Enrichment:** CLAP queue and failure cleanup fixes for enrichment debug mode
+
 ## [1.3.7] - 2026-02-01
 
 ### Added
@@ -69,6 +102,34 @@ Automatic detection of available analyzers with graceful degradation.
 - **Docker Profiles:** Replaced Docker profiles with override file approach for better compatibility
 - **Mood Columns:** Marked as legacy in schema - may be derived from CLAP embeddings in future
 
+## [1.3.5] - 2026-01-22
+
+### Fixed
+
+- **Audio preload:** Emit preload 'load' event asynchronously to prevent race condition during gapless playback
+
+## [1.3.4] - 2026-01-22
+
+### Added
+
+- **Gapless playback:** Preload infrastructure and next-track preloading for seamless transitions
+- **Infinite scroll:** Library artists, albums, and tracks now use infinite query pagination
+- **CachedImage:** Migrated to Next.js Image component with proper type support
+
+### Fixed
+
+- **CSS hover performance:** Fixed hover state performance issues
+- **Audio analyzer:** Fixed Enhanced mode detection
+- **Onboarding:** Accessibility improvements
+- **Audio format detection:** Simplified to prevent wrong decoder attempts
+- **Audio cleanup:** Improved Howl instance cleanup to prevent memory leaks
+- **Audio cleanup tracking:** Use Set for pending cleanup tracking
+- **Redis connections:** Disconnect enrichmentStateService connections on shutdown
+
+### Changed
+
+- **Library page:** Optimized data fetching with tab-based queries and memoized delete handlers
+
 ## [1.3.3] - 2026-01-18
