 ## [Unreleased]
 
+## [0.0.56-alpha] - 2021-09-10
+### Added
+- Add Smart Collections
+  - Smart Collections use search queries and can be created from the search result page
+  - Smart Collections are re-evaluated every time playouts are extended or rebuilt to automatically include newly-matching items
+  - This requires rebuilding the search index and search results may be empty or incomplete until the rebuild is complete
+- Allow `Shuffle In Order` with Collections and Smart Collections
+  - Episodes will be grouped by show, and music videos will be grouped by artist
+  - All movies will be a single group (multi-collections are probably better if `Shuffle In Order` is desired for movies)
+  - All groups will be be ordered chronologically (custom ordering is only supported in multi-collections)
+
+### Fixed
+- Generate XMLTV that validates successfully
+  - Properly order elements
+  - Omit channels with no programmes
+  - Properly identify channels using the format number.etv like `15.etv`
+- Fix building playouts when multi-part episode grouping is enabled and episodes are missing metadata
+- Fix incorrect total items count in `Multi Collections` table
+
+## [0.0.55-alpha] - 2021-09-03
+### Fixed
+- Fix all local library scanners to ignore dot underscore files (`._`)
+
+## [0.0.54-alpha] - 2021-08-21
+### Added
+- Add `Shuffle In Order` playback order for multi-collections.
+  - This is useful for randomizing multiple collections/shows on a single channel, while each collection maintains proper ordering (custom or chronological)
+
+### Fixed
+- Fix bug parsing ffprobe output in cultures where `.` is a group/thousands separator
+  - This bug likely prevented ETV from scheduling correctly or working at all in those cultures
+  - After installing a version with this fix, affected content will need to be removed from ETV and re-added
+
+## [0.0.53-alpha] - 2021-08-01
+### Fixed
+- Fix error message displayed after building empty playout
+- Fix Emby and Jellyfin links
+
+### Changed
+- Always proxy Jellyfin and Emby artwork; this fixes artwork in some networking scenarios
+
+## [0.0.52-alpha] - 2021-07-22
+### Added
+- Add multiple local libraries to better organize your media
+- Add `Move Library Path` function to support reorganizing existing local libraries
+
+### Fixed
+- Fix bug preventing playouts from rebuilding after an empty collection is encountered within a multi-collection
+
+## [0.0.51-alpha] - 2021-07-18
+### Added
+- Add `Multi Collection` to support shuffling multiple collections within a single schedule item
+  - Collections within a multi collection are optionally grouped together and ordered when scheduling; this can be useful for franchises
+- Add `Playout Days To Build` setting to control how many days of playout data/program guide data should be built into the future
+
+### Changed
+- Move `Playback Order` from schedule to schedule items
+  - This allows different schedule items to have different playback orders within a single schedule
+
+### Fixed
+- Fix release notes on home page with `-alpha` suffix
+- Fix linux-arm release by including SQLite interop artifacts
+- Fix issue where cached Plex credentials may become invalid when multiple servers are used
+
+## [0.0.50-alpha] - 2021-07-13
+### Added
+- Add Linux ARM release artifacts which can be used on Raspberry Pi devices
+
+### Fixed
+- Fix bug preventing ingestion of local movies with fallback metadata (without NFO files)
+- Fix extra spaces in titles of local movies with fallback metadata (without NFO files)
+
+## [0.0.49-prealpha] - 2021-07-11
+### Added
+- Include audio language metadata in all streaming modes
+- Add special zero-count case to `Multiple` playout mode
+  - This configuration will automatically maintain the multiple count so that it is equal to the number of items in the collection
+  - This configuration should be used if you want to play every item in a collection exactly once before advancing
+
+### Changed
+- Use case-insensitive sorting for collections page and `Add to Collection` dialog
+- Use case-insensitive sorting for all collection lists in schedule items editor
+- Use natural sorting for schedules page and `Add to Schedule` dialog
+
+### Fixed
+- Fix flooding schedule items that have a fixed start time
+
+## [0.0.48-prealpha] - 2021-06-22
+### Added
+- Store pixel format with media statistics; this is needed to support normalization of 10-bit media items
+  - This requires re-ingesting statistics for all media items the first time this version is launched
+
+### Changed
+- Use ffprobe to retrieve statistics for Plex media items (Local, Emby and Jellyfin libraries already use ffprobe)
+
+### Fixed
+- Fix playback of transcoded 10-bit media items (pixel format `yuv420p10le`) on Nvidia hardware
+- Emby and Jellyfin scanners now respect library refresh interval setting
+- Fix adding new seasons to existing Emby and Jellyfin shows
+- Fix adding new episodes to existing Emby and Jellyfin seasons
+
 ## [0.0.47-prealpha] - 2021-06-15

 - Add warning during playout rebuild when schedule has been emptied
