 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
 ## [Unreleased]
+### Fixed
+- Fix local folder scanners to properly detect removed/re-added folders with unchanged contents
+- Fix double-click startup on mac
+- Fix trakt list sync when show does not contain a year
+- Properly unlock libraries when a scan is unable to be performed because ffmpeg or ffprobe have not been found
+
+### Added
+- Add trash system for local libraries to maintain collection and schedule integrity through media share outages
+  - When items are missing from disk, they will be flagged and present in the `Media` > `Trash` page
+  - The trash page can be used to permanently remove missing items from the database
+  - When items reappear at the expected location on disk, they will be unflagged and removed from the trash
+- Add basic Mac hardware acceleration using VideoToolbox
+
+### Changed
+- Local libraries only: when items are missing from disk, they will be added to the trash and no longer removed from collections, etc.
+- Show song thumbnail in song list
+
+## [0.3.6-alpha] - 2022-01-10
+### Fixed
+- Properly index `minutes` field when adding new items during scan (vs when rebuilding index)
+- Fix some nvenc edge cases where only padding is needed for normalization
+- Properly overwrite environment variables for ffmpeg processes (`LIBVA_DRIVER_NAME`, `FFREPORT`)
+
+### Added
+- Add music video `artist` to search index
+  - This requires rebuilding the search index and search results may be empty or incomplete until the rebuild is complete
+
+### Changed
+- Remove `HLS Hybrid` streaming mode; all channels have been reconfigured to use the superior `HLS Segmenter` streaming mode
+- Update `MPEG-TS` streaming mode to internally use the HLS segmenter
+  - This improves compatibility with many clients and also improves performance at program boundaries
+- Renamed existing `MPEG-TS` mode as `MPEG-TS (Legacy)`
+  - This mode will be removed in a future release
+
+## [0.3.5-alpha] - 2022-01-05
+### Fixed
+- Fix bundled ffmpeg version in base docker image (NOT nvidia or vaapi) which prevented playback since v0.3.0-alpha
+- Use software decoding for mpeg4 content when VAAPI acceleration is enabled
+- Fix hardware acceleration health check to recognize QSV on non-Windows platforms
+
+### Changed
+- Treat `setsar` as a hardware filter, avoiding unneeded `hwdownload` and `hwupload` steps when padding isn't required
+
+## [0.3.4-alpha] - 2021-12-21
+### Fixed
+- Fix other video and song scanners to include videos contained directly in top-level folders that are added to a library
+- Allow saving ffmpeg troubleshooting reports on Windows
+
+## [0.3.3-alpha] - 2021-12-12
+### Fixed
+- Fix bug with saving multiple blurhash versions for cover art; all cover art will be automatically rescanned
+- Fix song detail margin when no cover art exists and no watermark exists
+- Fix synchronizing virtual shows and seasons from Jellyfin
+- Properly sort channels in M3U
+
+### Changed
+- Use blurhash of ErsatzTV colors instead of solid colors for default song backgrounds
+- Use select control instead of autocomplete control in many places
+    - The autocomplete control is not intuitive to use and has focus bugs
+
+## [0.3.2-alpha] - 2021-12-03
+### Fixed
+- Fix artwork upload on Windows
+- Fix unicode song metadata on Windows
+- Fix unicode console output on Windows
+- Fix TV Show NFO metadata processing when `year` is missing
+- Fix song detail outline to help legibility on white backgrounds
+- Optimize song artwork scanning to prevent re-processing album artwork for each song
+
+### Changed
+- Use custom log database backend which should be more portable (i.e. work in osx-arm64)
+- Use cover art blurhashes for song backgrounds instead of solid colors or box blur
+
+## [0.3.1-alpha] - 2021-11-30
+### Fixed
+- Fix song page links in UI
+- Show song artist in playout detail
+- Include song artist and cover art in channel guide (xmltv)
+- Use subtitles to display errors, which fixes many edge cases of unescaped characters
+- Properly split song genre tags
+- Properly display all songs that have an identical album and title
+- Fix channel logo and watermark uploads
+- Fix regression introduced with `v0.2.4-alpha` that caused some filler edge cases to crash the playout builder
+
+### Added
+- Add song genres to search index
+- Use embedded song cover art when sidecar cover art is unavailable
+
+### Changed
+- Randomly place song cover art on left or right side of screen
+- Randomly use a solid color from the cover art instead of blurred cover art for song background
+- Randomly select song detail layout (large title/small artist or small artist/title/album)
+
+## [0.3.0-alpha] - 2021-11-25
+### Fixed
+- Properly fix database incompatibility introduced with `v0.2.4-alpha` and partially fixed with `v0.2.5-alpha`
+  - The proper fix requires rebuilding all playouts, which will happen on startup after upgrading
+- Fix local library locking/progress display when adding paths
+- Fix grouping duration items in EPG when custom title is configured
+
+### Added
+- Add *experimental* `Songs` local libraries
+    - Like `Other Videos`, `Songs` require no metadata or particular folder layout, and will have tags added for each containing folder
+    - For Example, a song at `rock/band/1990 - Album/01 whatever.flac` will have the tags `rock`, `band` and `1990 - Album`, and the title `01 whatever`
+    - Songs will also have basic metadata read from embedded tags (album, artist, title)
+    - Video will be automatically generated for songs using metadata and cover art or watermarks if available
+- Add support for `.webm` video files
+
+## [0.2.5-alpha] - 2021-11-21
+### Fixed
+- Include other video title in channel guide (xmltv)
+- Fix bug introduced with 0.2.4-alpha that caused some playouts to build from year 0
+- Use less memory matching Trakt list items
+
+### Added
+- Build osx-arm64 packages on release
+
+### Changed
+- No longer warn about local Plex guids; they aren't used for Trakt matching and can be ignored
+
+## [0.2.4-alpha] - 2021-11-13
+### Changed
+- Upgrade to dotnet 6
+- Use `scale_cuda` instead of `scale_npp` for NVIDIA scaling in all cases
 
 ## [0.2.3-alpha] - 2021-11-03
 ### Fixed
