Complete Version history / Release notes / Changelog / What's New for hls-downloader
5.4.4
Fixes
Fixed the Firefox Add-ons publish command argument handling so AMO receives the listed-channel submission and matching source archive.
Ensured failed AMO uploads still remove temporary source archives.
Testing
GitHub release workflow
v5.4.0
Features
Auto delete after save: optionally remove completed downloads from the list after saving (#506).
Fixes
Preserve embedded audio in muxed HLS streams instead of silently dropping the audio track (#507).
Sanitize download filenames to remove illegal characters that could cause save failures (#505).
Fix white text on white background in native select elements when using Firefox dark theme (#504).
v5.3.0
Features
Storage management: per-bucket size tracking, quota monitoring with near-quota warnings, one-click cleanup of all stored data, and storage summary in downloads and settings views.
Duration estimation: fetch playlist durations from EXTINF tags and display expected download sizes per job.
Fixes
Fixed race condition in bucket metadata tracking under concurrent fragment writes (serialized per-bucket updates).
Fixed deleteBucket removing data from cache before IndexedDB deletion succeeds, which could orphan invisible data.
Fixed cleanupSuccess reducer computing availableBytes from potentially-unset quotaBytes.
Fixed measureBucketUsage not closing the database on error and using incorrect transaction completion pattern.
Fixed cleanup() skipping remaining databases when a single deletion fails.
Fixed InlineConfirm dismissing the confirm buttons before the async cleanup operation completes.
Added null guards in jobsSlice reducers to prevent crashes on stale job IDs after cleanup.
Added descriptive error messages to bare throw Error() calls in IndexedDB operations.
Added concurrency limit (4) to fetchLevelDurationEpic to prevent unbounded parallel fetches.
Tests
Added 23 integration tests for storage epics (fetchStorageStatsEpic, autoRefreshStorageStatsEpic, cleanupStorageEpic).
Added 13 unit tests for storage use-case edge cases and storageSlice reducers.
5.2.0
Features
Subtitle downloads end-to-end: fetch VTT tracks, generate language-aware filenames, and mux into MKV when subtitles are present.
Richer audio and subtitle selection: parse default/autoselect/forced flags and group IDs, honor a preferred audio language, persist per-playlist audio/subtitle choices, and block downloads on unsupported encryption.
Sniffer gains direct URL entry and streamlined navigation (Direct tab removed); playlist UI shows metadata badges and quick copy buttons for track URLs.
Job cards and About/Settings views refreshed with clearer status, hover/copy affordances, and Storybook scenarios seeded with realistic store state.
Fixes
More robust muxing pipeline with offscreen document fallback for MV3 and safer bucket cleanup when generating download blobs.
Chores
Vite/tooling upgrade (vite 6.4.1, pnpm 10.11.0) and Storybook now runs from the popup package.
CI/release workflow tweaks: fixed permissions for publishing/coverage, added coverage badge workflow, removed CodeQL.
Added feature overview doc and pruned planning docs.
5.1.0
Features
Manifest V3 support for Chromium browsers using an offscreen document to create blob URLs in the service-worker background.
Dual build pipeline with separate MV2 (Firefox/Chromium) and MV3 (Chromium) artifacts and clearer tester instructions.
Fixes
Ensure MV2 background bundles emit as background.js and package popup/background files into the root of the ZIP/XPI for direct installs.
Chores
CI builds both MV2 and MV3 targets; release uploads MV2 Firefox/Chromium and MV3 Chromium artifacts.
Added “For Dear Testers” guide for Firefox/Chromium reviewers and clarified MV3 Chromium-only caveat.
