 # Changelog
 
+## [2.0.2] - 2026-01-03
+
+### Added
+- **Actual Quality Display**: Shows real audio quality (bit depth/sample rate) after download
+  - Quality badge on download history items (e.g., "24-bit", "16-bit")
+  - Full quality info in Track Metadata screen (e.g., "24-bit/96kHz")
+  - Tertiary color highlight for Hi-Res (24-bit) downloads
+- **Quality Disclaimer**: Added note in quality picker explaining that actual quality depends on track availability
+- **Instant Lyrics Loading**: Lyrics now load from embedded file first (instant) before falling back to internet fetch
+
+### Fixed
+- **Fallback Service Display**: Fixed download history showing wrong service when fallback occurs (e.g., showing "TIDAL" when actually downloaded from "QOBUZ")
+- **Open in Spotify**: Fixed "Open in Spotify" button not opening Spotify app correctly
+
+### Removed
+- **Romaji Conversion**: Removed Japanese lyrics to romaji conversion feature (Kanji not supported, results were incomplete)
+
+### Technical
+- Go backend now returns `actual_bit_depth` and `actual_sample_rate` in download response
+- Go backend now returns `service` field indicating actual service used (important for fallback)
+- Tidal API v2 response provides exact quality info
+- Qobuz uses track metadata for quality info
+- Amazon now reads quality from downloaded FLAC file (previously returned unknown)
+
+## [2.0.1] - 2026-01-03
+
+### Added
+- **Quality Picker Track Info**: Shows track name, artist, and cover in quality picker
+  - Tap to expand long track titles
+  - Expand icon only shows when title is truncated
+  - Ripple effect follows rounded corners including drag handle
+
+### Changed
+- **Unified Progress Tracking System**: Deprecated legacy single-download progress
+  - All downloads now use item-based progress tracking
+  - Fixes duplicate notification bug when finalizing
+  - Cleaner codebase with single progress system
+
+### Fixed
+- **Duplicate Notification Bug**: Fixed issue where "Finalizing" and "Downloading" notifications appeared simultaneously
+- **Update Notification Stuck**: Fixed notification staying at 100% after download completes
+- **Quality Picker Consistency**: Unified quality picker UI across all screens (Home, Album, Playlist)
+  - Container with `primaryContainer` background for each option
+  - Distinct icons: music_note (Lossless), high_quality (Hi-Res), four_k (Max)
+
+## [2.0.0] - 2026-01-03
+
+### Added
+- **Artist Search Results**: Search now shows artists alongside tracks
+  - Horizontal scrollable artist cards with circular avatars
+  - Tap artist to view their discography
+- **Multi-Layer Caching System**: Aggressive caching to minimize API calls
+  - Go backend cache: Artist (10 min), Album (10 min), Search (5 min)
+  - Flutter memory cache: Instant navigation for previously viewed artists/albums
+  - Duplicate search prevention: Same query won't trigger new API call
+- **Real-time Download Status**: Track items show live download progress
+  - Queued: Hourglass icon
+  - Downloading: Circular progress with percentage
+  - Completed: Check icon
+  - Works in Home search, Album, and Playlist screens
+- **Downloaded Track Indicator**: Tracks already in history show check mark
+  - Lazy file verification: Only checks file existence when tapped
+  - Auto-removes from history if file was deleted, allowing re-download
+  - Prevents accidental duplicate downloads
+- **Pre-release Support**: GitHub Actions auto-detects preview/beta/rc/alpha tags
+  - Stable users won't receive update notifications for preview versions
+
+### Changed
+- **Instant Navigation UX**: Navigate to Artist/Album screens immediately
+  - Header (name, cover) shows instantly from available data
+  - Content (albums/tracks) loads in background inside the screen
+  - Second visit to same artist/album is instant from Flutter cache
+- **Search Results UI Redesign**: 
+  - Removed "Download All" button from search results
+  - Added "Songs" section header (matches "Artists" header style)
+  - Track list now in grouped card with rounded corners (like Settings)
+  - Track items with dividers and InkWell ripple effect
+- **Larger UI Elements**: Improved touch targets and visual hierarchy
+  - Recent downloads: Album art 56→100px, section height 80→130px
+  - Artist cards: Avatar 72→88px, container 90→100px
+  - Track items: Album art 48→56px
+- **Optimized Search**: Pressing Enter with same query no longer triggers duplicate search
+- **Smoother Progress Animation**: Progress jumps to 100% after download completes
+  - Embedding (cover, metadata, lyrics) happens in background without blocking UI
+- **Finalizing Status**: Shows "Finalizing" indicator while embedding metadata
+  - Distinct icon (edit_note) with tertiary color
+  - User knows download is complete, just processing metadata
+- **Consistent Download Button Sizes**: All download/status buttons now 44x44px
+- **Better Dynamic Color Contrast**: Improved visibility for cards and chips with dynamic color
+  - Settings cards use overlay colors for better contrast
+  - Theme/view mode chips have visible borders in light mode
+- **Navigation Bar Styling**: Distinct background color from content area
+- **Ask Before Download Default**: Now enabled by default for better UX
+
+### Fixed
+- **Artist Profile Images**: Fixed artist images not showing in search results (field name mismatch)
+- **Album Card Overflow**: Fixed 5px overflow in artist discography album cards
+- **Optimized Rebuilds**: Each track item only rebuilds when its own status changes
+  - Uses Riverpod `select()` for granular state watching
+  - Prevents entire list rebuild on progress updates
+- **Update Notification Stuck**: Fixed notification staying at 100% after download complete
+
+## [1.6.3] - 2026-01-03
+
+### Added
+- **Predictive Back Navigation**: Support for Android 14+ predictive back gesture with smooth animations
+- **Separate Detail Screens**: Album, Artist, and Playlist now open as dedicated screens with Material Expressive 3 design
+  - Collapsing header with cover art and gradient overlay
+  - Card-based info section with rounded corners (20px radius)
+  - Tonal download buttons with circular shape
+  - Quality picker bottom sheet with drag handle
+- **Double-Tap to Exit**: Press back twice to exit app when at home screen (replaces exit dialog)
+
+### Changed
+- **Navigation Architecture**: Refactored from state-based to screen-based navigation
+  - Album/Artist/Playlist URLs navigate to dedicated screens via `Navigator.push()`
+  - Enables native predictive back gesture animations
+  - Search results stay on Home tab for quick downloads
+- **Simplified State Management**: Removed `previousState` chain from TrackProvider since Navigator handles back navigation
+
+## [1.6.2] - 2026-01-02
+
+### Added
+- **HTTPS-Only Downloads**: APK downloads and update checks now enforce HTTPS-only connections for security
+
+### Changed
+- **Home Tab Rename**: Renamed "Search" tab to "Home" with home icon
+- **Branding**: Changed idle screen title from "Search Music" to "SpotiFLAC"
+- **About Page Redesign**: New Material Expressive 3 grouped layout with app header, contributors section with GitHub avatars, and organized links
+
+### Fixed
+- **Play Button Flash**: Fixed play button briefly showing red error icon on app start (now uses optimistic rendering)
+
+### Performance
+- **Optimized State Management**: Use `.select()` for Riverpod providers to prevent unnecessary widget rebuilds
+- **List Keys**: Added keys to all list builders for efficient list updates and reordering
+- **Request Cancellation**: Outdated API requests are ignored when new search/fetch is triggered
+- **Debounced URL Fetches**: All network requests now debounced to prevent rapid duplicate calls
+- **Bounded File Cache**: File existence cache now limited to 500 entries to prevent memory leak
+- **Timer Cleanup**: Progress polling timer properly disposed when provider is destroyed
+- **Stream Error Handling**: Share intent stream now has proper error handling
+
