 ## [Unreleased]
 
+## [0.0.58-alpha] - 2021-09-15
+### Added
+- Add `released_notinthelast` search field for relative release date queries
+  - Syntax is a number and a unit (days, weeks, months, years) like `1 week` or `2 years`
+- Add `released_onthisday` search field for historical queries
+  - Syntax is `released_onthisday:1` and will search for items released on this month number and day number in prior years
+- Add tooltip explaining `Keep Multi-Part Episodes Together`
+
+### Fixed
+- Properly display watermark when no other video filters (like scaling or padding) are required
+- Fix building some playouts in timezones with positive offsets (like UTC+2)
+- Fix `Shuffle In Order` so all collections/shows start from the earliest episode
+  - You may need to rebuild playouts to see this fixed behavior more quickly
+
+## [0.0.57-alpha] - 2021-09-10
+### Added
+- Add `released_inthelast` search field for relative release date queries
+  - Syntax is a number and a unit (days, weeks, months, years) like `1 week` or `2 years`
+- Allow adding smart collections to multi collections
+
+### Fixed
+- Fix loading artwork in Kodi
+  - Use fake image extension (`.jpg`) for artwork in M3U and XMLTV since Kodi detects MIME type from URL
+  - Enable HEAD requests for IPTV image paths since Kodi requires those
+
+## [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
