Linthra v0.1.11

Linthra v0.1.11 — release notes

Linthra is an Android music player for local files and self-hosted music
servers. v0.1.11 is a folder-browsing and Android navigation release. It
adds a real server-folder view for Jellyfin and Navidrome/Subsonic and makes the
Android system Back button follow Linthra's navigation before exiting the app.

• Version: 0.1.11 (versionName), versionCode 111999
• Platform: Android
• Application ID: io.github.thezupzup.linthra
• License: MPL-2.0
• Get it: Available from the
  GitHub Releases page first

  F-Droid build
  follows after F-Droid detects the tag and completes its build process.

What's new

Browse by folder hierarchy

• New Folders tab. Library now includes a Folders tab when a compatible
  Jellyfin or Navidrome/Subsonic server is connected.
• Real server structure. Browse the hierarchy exposed by the server instead
  of relying only on Linthra's flat Songs, Albums, and Artists views.
• Direct playback. Songs found inside a folder can be started immediately
  using Linthra's existing playback queue and track actions.
• Separate connected sources. Jellyfin and Navidrome/Subsonic roots are
  shown independently when both are connected.
• Lightweight navigation. Linthra requests one folder level at a time rather
  than recursively downloading the complete directory tree.
• Friendly states. Loading, empty-folder, error, and retry states are handled
  inside the folder browser.

Android Back navigation

• Nested folders return correctly. Android Back moves to the previous folder
  before leaving the Folders tab.
• Detail screens return normally. Album, artist, playlist, player, support,
  and settings-detail screens return to their parent screen.
• Main tabs return to Library. Back from the root of Playlists, Downloads,
  or Settings returns to Library instead of closing Linthra immediately.
• Exit only from the true root. Linthra closes normally only when Back is
  pressed from the root of Library with no internal state left to dismiss.
• Existing tab history is preserved. The independent navigation stack and
  scroll position of each bottom-navigation tab remain intact.

Technical summary

• Provider-neutral folder capability
  (PR #289, closes
  #282): a small optional
  folder-browsing contract lets supported providers expose root folders and one
  immediate child level without changing the normal music-source interface.
• Jellyfin folder browser: reads music roots from /Library/MediaFolders
  and direct child folders/tracks from /Items with non-recursive requests.
• Navidrome/Subsonic folder browser: reads music roots through
  getMusicFolders, indexes through getIndexes, and nested directories through
  getMusicDirectory.
• Credential-safe identifiers: folder IDs stay opaque and never include an
  authenticated URL, password, token, or other secret.
• Central Android Back handling
  (PR #289, closes
  #285): root and branch
  navigators now cooperate so internal state is handled before the app exits.

No dependency, Drift schema, account, playlist, download, cache, or media-library
data migration is included in this release.

Manual QA completed

• Browse a real Jellyfin folder hierarchy.
• Open nested folders and start a song directly from Folders.
• Use Android Back to return through nested folders.
• Use Android Back across Linthra detail screens and main tabs.
• Exit normally from the Library root.
• Dart formatting, Flutter analysis, full tests, privacy scan, Android debug
  build, and GitHub Sponsor simulation passed on the feature PR.

Upgrade and distribution notes

• No settings reset or database migration is required.
• Don't mix install sources. A GitHub-release APK is signed with Linthra's
  key, while the F-Droid build is signed with F-Droid's key; the two cannot
  update each other. Stay with one source.
• F-Droid detects stable tags automatically and builds from source. The local
  metadata mirror can be updated after tagging with the final tag commit SHA and
  per-ABI version codes.

No ads, no tracking, no analytics, no telemetry. Linthra plays music you already
own or that your own server provides.
