 ## [Unreleased]

+## [0.1.1-alpha] - 2021-10-10
+### Added
+- Add music video album to search index
+  - This requires rebuilding the search index and search results may be empty or incomplete until the rebuild is complete
+
+### Changed
+- Remove forced initial delay from `HLS Segmenter` streaming mode
+- Upgrade nvidia docker image from 18.04 to 20.04
+
+## [0.1.0-alpha] - 2021-10-08
+### Added
+- Add *experimental* streaming mode `HLS Segmenter` (most similar to `HLS Hybrid`) 
+  - This mode is intended to increase client compatibility and reduce issues at program boundaries
+  - If you want the temporary transcode files to be located on a particular drive, the docker path is `/root/.local/share/etv-transcode`
+- Store frame rate with media statistics; this is needed to support HLS Segmenter
+  - This requires re-ingesting statistics for all media items the first time this version is launched
+
+### Changed
+- Use latest iHD driver (21.2.3 vs 20.1.1) in vaapi docker images
+
+### Fixed
+- Add downsampling to support transcoding 10-bit HEVC content with the h264_vaapi encoder
+- Fix updating statistics when media items are replaced
+- Fix XMLTV generation when scheduled episode is missing metadata
+
+## [0.0.62-alpha] - 2021-10-05
+### Added
+- Support IMDB ids from Plex libraries, which may improve Trakt matching for some items
+
+### Fixed
+- Include Specials/Season 0 `episode-num` entry in XMLTV
+- Fix some transcoding edge cases with VAAPI and pixel formats `yuv420p10le`, `yuv444p10le` and `yuv444p`
+- Update Plex movie and episode paths when they are changed within Plex
+- Always use `libx264` software encoder for error messages
+
+## [0.0.61-alpha] - 2021-09-30
+### Fixed
+- Revert nvenc/cuda filter change from v60
+
+## [0.0.60-alpha] - 2021-09-25
+### Added
+- Add Trakt list support under `Lists` > `Trakt Lists`
+  - Trakt lists can be added by url or by `user/list`
+  - To re-download a Trakt list, simply add it again (no need to delete)
+  - See `Logs` for unmatched item details
+  - Trakt lists can only be scheduled by using Smart Collections
+- Add seasons to search index
+  - This is needed because Trakt lists can contain seasons 
+  - This requires rebuilding the search index and search results may be empty or incomplete until the rebuild is complete
+
+### Fixed
+- Fix local television scanner to properly update episode metadata when NFO files have been added/changed
+- Properly detect ffmpeg nvenc (cuda) support in Hardware Acceleration health check
+- Fix nvenc/cuda filter for some yuv420p content
+
+## [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
+- 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
