 ## [Unreleased]
 
+## [0.0.59-alpha] - 2021-09-18
+### Added
+- Add `Health Checks` table to home page to identify and surface common misconfigurations
+  - `FFmpeg Version` checks `ffmpeg` and `ffprobe` versions
+  - `FFmpeg Reports` checks whether ffmpeg troubleshooting reports are enabled since they can use a lot of disk space over time
+  - `Hardware Acceleration` checks whether channels that transcode are using acceleration methods that ffmpeg claims to support
+  - `Movie Metadata` checks whether all movies have metadata (fallback metadata counts as metadata)
+  - `Episode Metadata` checks whether all episodes have metadata (fallback metadata counts as metadata)
+  - `Zero Duration` checks whether all movies and episodes have a valid (non-zero) duration
+  - `VAAPI Driver` checks whether a vaapi driver preference is configured when using the vaapi docker image
+- Add setting to each playout to schedule an automatic daily rebuild
+  - This is useful if the playout uses a smart collection with `released_onthisday`
+
+### Fixed
+- Fix docker vaapi support for newer Intel platforms (Gen 8+)
+  - This includes a new setting to force a particular vaapi driver (`iHD` or `i965`), as some Gen 8 or 9 hardware that is supported by both drivers will perform better with one or the other
+- Fix scanning and indexing local movies and episodes without NFO metadata
+- Fix displaying seasons for shows with no year (in metadata or in folder name)
+- Fix "direct play" in MPEG-TS mode (copy audio and video stream when `Transcode` is unchecked)
+
+## [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
