+
+## [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

+### Added
+- Include audio language metadata in all streaming modes
+- Add special zero-count case to `Multiple` playout mode

+
+### Changed
+- Use ffprobe to retrieve statistics for Plex media items (Local, Emby and Jellyfin libraries already use ffprobe)
+
+### Fixed

+  - This allows easy watermark reuse across channels
+
+### Fixed

+- Fix many potential sources of inconsistent data in UI
+
+## [0.0.45-prealpha] - 2021-06-12

+- Fix bug replacing music videos
+- Scan Plex libraries and local libraries on different threads
+- Use English names for preferred languages in UI instead of ISO language code
+
+## [0.0.28-prealpha] - 2021-04-03
+- Apply audio normalization more consistently; this should further reduce program boundary errors
+- Replace unused audio volume setting with audio loudness normalization option
+    - This can be particularly helpful with music video channels if media items have inconsistent loudness

+- Fix XMLTV containing music videos that do not use a custom title
+- Fix channels table sorting, add paging to channels table
+- Add sorting and paging to schedules table
+- Add paging to playouts table

+    - Artists can be searched using the `artist` field, like `artist:daft`
+- Clear search query when clicking `Movies` or `TV Shows` from paged search results
+- Add show title to playout details
+- Let ffmpeg determine thread count by default (signified by `0` threads in ffmpeg profile)
+- Save troubleshooting reports for ffmpeg concat process in addition to transcode process
+- Simplify ffmpeg normalization options
+- Add frame rate setting to ffmpeg profile
+    - When video normalization is enabled, all media items will have their frame rate converted to the same value
+- Fix some scenarios where streaming would freeze at program boundaries
+- Fix bug preventing some Plex libraries from scanning
+- Fix bug preventing some local libraries from scanning folders that were recently added
+
+## [0.0.26-prealpha] - 2021-03-30

+- Navigate to schedule items after creating new schedule
+- Fix channel editor so preferred language is no longer required on every channel
+- Fix bug with audio track selection during non-normalized playback
+- Fix bug with playout builds where `Multiple` or `Duration` items wouldn't respect the settings over time
+- Fix bug that prevented some television folders from scanning
+
+## [0.0.25-prealpha] - 2021-03-29
+- Add preferred language feature
+    - Global preference can be set in FFmpeg settings; channels can override global preference
+    - Preferences require [ISO 639-2](https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes) language codes
+    - Audio stream selection will attempt to respect these preferences and prioritize streams with the most channels
+    - English (`eng`) will be used as a fallback when no preferences have been configured
+    - ***This feature requires a one-time reanalysis of every media item which may take a long time for large libraries and playback may fail until this scan has completed***
+- Fix channel sorting in EPG
+- Fix mixed-platform path replacements (Plex on Windows with ErsatzTV on Linux, or Plex on Linux with ErsatzTV on Windows)
+- Fix local television library scanning; this was broken with `v0.0.23`
+- Optimize local library scanning; regular scans should be significantly faster
+- Add log warning when a zero-duration media item is encountered
+- Fix indexing local shows without NFO metadata.
+    - If you have this issue the best way to fix is to:
+        - Shutdown ErsatzTV
+        - Delete the `search-index` subfolder inside the ErsatzTV config folder
+        - Start ErsatzTV; the full search index will be rebuilt on startup
+- Fix updating search index when genres, tags, studios are updated in local libraries
+- Adjust artwork routes so all IPTV traffic can be proxied with a single path prefix of `/iptv`
+
+## [0.0.24-prealpha] - 2021-03-22

+    - Fields that aren't searched by default, but can be included in queries with syntax like (`plot:whatever`):
+        - `plot`
+        - `library_name`
+        - `type` (`movie` or `show`)
+    - Add letter bar to all paged search results to quickly navigate to a particular letter
