 ## [Unreleased]
 
+## [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
 - Fix bug with audio filter in cultures where `.` is a group/thousands separator
