bump version to 3.8.6+112

When a file is converted externally (e.g. FLAC to OPUS), the
orphan cleanup would delete the history entry because the original
path no longer exists. Now it checks for sibling files with other
audio extensions and updates the stored path instead of deleting.

Also add extension-stripped keys to path_match_keys so that
paths differing only by audio extension still match during local
library scan exclusion and queue deduplication.

 # Changelog
 
+## [3.7.2] - 2026-03-07
+
+### Changed
+
+- **Amazon Music is now an Extension**: Amazon Music has been moved from a built-in service to a separate installable extension. Install the "Amazon Music" extension from the Store to continue using it.
+
+### Fixed
+
+- **Deezer Downloads Timing Out**: Deezer downloads were failing with "context deadline exceeded" on larger files. Now uses the proper download timeout, matching Tidal and Qobuz.
+- **iOS Local Library Scan Fails**: Local library scanning was failing on iOS because the app lost access to user-picked folders after the FilePicker session ended. Implemented iOS security-scoped bookmark system:
+  - When a library folder is picked on iOS, a security-scoped bookmark is created and persisted in settings (`localLibraryBookmark`)
+  - Before each scan, the bookmark is resolved and security-scoped access is started; access is released in `finally` block after scan completes
+  - `cleanupMissingFiles` also activates the bookmark before checking file existence on iOS
+  - New `AppDelegate.swift` method channel handlers: `createIosBookmarkFromPath`, `startAccessingIosBookmark`, `stopAccessingIosBookmark`, `resolveIosBookmark`
+  - New `PlatformBridge` methods: `createIosBookmarkFromPath()`, `startAccessingIosBookmark()`, `stopAccessingIosBookmark()`
+  - All scan call-sites (Library Settings, Queue tab, Local Album screen) now pass the iOS bookmark to `startScan()`
+
+### Added
+
+- **Amazon Music Extension**: Available in `extension/Amazon-SpotiFLAC/` — same functionality as before, now as an installable extension.
+- **Accessibility Tooltips**: Added localized tooltips to all `IconButton` and `PopupMenuButton` widgets across the entire UI for screen reader and long-press discoverability
+  - Back buttons use `MaterialLocalizations.backButtonTooltip`
+  - Close buttons use `MaterialLocalizations.closeButtonTooltip`
+  - Menu buttons use `MaterialLocalizations.showMenuTooltip`
+  - Search buttons use `MaterialLocalizations.searchFieldLabel`
+  - Contextual actions use descriptive labels: "Play track", "Dismiss", "Clear search", "Change folder", "Refresh"
+  - Screens affected: Album, Artist, Playlist, Downloaded Album, Local Album, Home, Search, Queue, Library Playlists, Library Tracks Folder, Setup, Tutorial, Track Metadata, Store, Extension Store Details, and all Settings sub-pages (About, Appearance, Cache Management, Donate, Download, Extensions, Extension Detail, Library, Log, Options, Provider Priority)
+- **Semantics Wrappers**: Added `Semantics` widgets to interactive elements that previously had no accessibility information
+  - Album tiles in Artist screen: announces selection state and album name
+  - Recently downloaded track tiles in Home tab: announces track name and artist
+  - Explore items (albums/artists/playlists) in Home tab: announces item type and name
+  - Color palette picker in Appearance settings: announces selected state and color hex value
+  - Download button demo in Tutorial screen: added `ExcludeSemantics` on icon to prevent duplicate screen reader announcements
+  - Queue tab playlist cards: announces playlist name and item count
+  - Queue tab downloaded album cards: announces album name, artist, and track count
+  - Queue tab local album cards: announces album name, artist, and track count
+  - Queue tab play button on completed downloads: announces track name and artist with `ExcludeSemantics` on icon
+  - Queue tab download status indicators: "Finalizing download", "Download completed", "Downloaded file missing" labels with `ExcludeSemantics` on icons
+
+### Improved
+
+- **Code Formatting**: Reformatted and corrected indentation across multiple files to comply with Dart style guidelines
+  - `extension_detail_page.dart`: Fixed `SliverAppBar` and all subsequent slivers indentation (was 2 spaces short)
+  - `log_screen.dart`: Fixed `SliverAppBar` indentation alignment
+  - `donate_page.dart`: Reformatted ternary expressions and `_cr` function body
+  - `library_tracks_folder_screen.dart`: Minor line-break formatting
+
+---

 ## Extensions
 
 Extensions allow the community to add new music sources and features without waiting for app updates. When a streaming service API changes or a new source becomes available, extensions can be updated independently.
 
 ### Installing Extensions
 1. Go to **Store** tab in the app
-2. Browse and install extensions with one tap
-3. Or download a `.spotiflac-ext` file and install manually via **Settings > Extensions**
-4. Configure extension settings if needed
-5. Set provider priority in **Settings > Extensions > Provider Priority**
+2. When opening the Store for the first time, you will be asked to enter an **Extension Repository URL**
+3. Browse and install extensions with one tap
+4. Or download a `.spotiflac-ext` file and install manually via **Settings > Extensions**
+5. Configure extension settings if needed
+6. Set provider priority in **Settings > Extensions > Provider Priority**

 ## FAQ
 
+**Q: Why does the Store tab ask me to enter a URL?**  
+A: Starting from version 3.8.0, SpotiFLAC uses a decentralized extension repository system — extensions are hosted on GitHub repositories rather than a built-in server, so anyone can create and host their own. Enter a repository URL in the Store tab to browse and install extensions.
+
 **Q: Why is my download failing with "Song not found"?**  
-A: The track may not be available on Tidal, Qobuz, or Amazon Music. Try enabling more download services in Settings > Download > Provider Priority, or install additional extensions from the Store.
+A: The track may not be available on the streaming services. Try enabling more download services in Settings > Download > Provider Priority, or install additional extensions like Amazon Music from the Store.
 
 **Q: Why are some tracks downloading in lower quality?**  
-A: Quality depends on what's available from the streaming service. Tidal offers up to 24-bit/192kHz, Qobuz up to 24-bit/192kHz, and Amazon up to 24-bit/48kHz. The app automatically selects the best available quality.
+A: Quality depends on what's available from the streaming service and extensions. Built-in providers: Tidal offers up to 24-bit/192kHz, Qobuz up to 24-bit/192kHz, and Deezer up to 16-bit/44.1kHz.
 
 **Q: Can I download playlists?**  
 A: Yes! Just paste the playlist URL in the search bar. The app will fetch all tracks and queue them for download.

 **Q: Why is download not working in my country?**  
 A: Some countries have restricted access to certain streaming service APIs. If downloads are failing, try using a VPN to connect through a different region.
 
+**Q: Can I add SpotiFLAC to AltStore or SideStore?**
+A: Yes! You can add the official source to receive updates directly within the app. Just copy this link:
+https://raw.githubusercontent.com/zarzet/SpotiFLAC-Mobile/refs/heads/main/apps.json
+In AltStore/SideStore, go to the Browse tab, tap Sources at the top, then tap the + icon and paste the link.
