+- Optimize Plex TV Scanner to quickly process shows that have not been updated since the last scan

+
+### Fixed
+- Fix ingesting actors and actor artwork from newly-added Plex media items
+- Only show `movie` and `show` libraries from Plex. Other library types are not supported at this time.

+
+## [0.0.34-prealpha] - 2021-04-17
+### Added
+- Allow `enter` key to submit all dialogs
+- Add actors to movies and shows (Plex or NFO metadata is required)

+- Rework metadata list links in UI (languages, studios, genres, etc)
+
+### Fixed
+- Fix EPG generation with music video channels that do not use a custom title
+- Fix lag when typing in search bar, `Add To Collection` dialog

+- Limit channels to one playout per channel
+    - Though more than one playout was previously possible it was unsupported and unlikely to work as expected, if at all
+    - A future release may make this possible again
+    
+## [0.0.32-prealpha] - 2021-04-09
+### Added
+- `Add All To Collection` button to quickly add all search results to a collection
+- Add Artists scanned from Music Video libraries

+- Send all audio streams with HLS when channel has no preferred language
+- Move FFmpeg settings to new `Settings` page
+- Add HDHR tuner count setting to new `Settings` page
+
+### Fixed

+
+## 0.0.30-prealpha [YANKED]
+
+## [0.0.29-prealpha] - 2021-04-04
+- No longer require NFO metadata for music videos
+    - Instead, the only requirement is that music video files be named `[artist] - [track].[extension]` where the three characters (space dash space) between artist and track are required
+- Add library scan progress detail
+- Optimize library scans after adding library path to only scan new library path
+- 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
+    - This setting may be less desirable on movie channels where loudness is intended to be dynamic
+- 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
+- Use table instead of cards for collections view
+
+## [0.0.27-prealpha] - 2021-04-02
+- Add ***basic*** music video library support
+    - **NFO metadata is required for music videos** - see [tags](https://kodi.wiki/view/NFO_files/Music_videos#Music_Video_Tags), [template](https://kodi.wiki/view/NFO_files/Music_videos#Template_nfo) and [sample](https://kodi.wiki/view/NFO_files/Music_videos#Sample_nfo)
+    - 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
+- Add `Custom Title` option to schedule items
+    - When a custom title is set, the schedule item will be grouped in the EPG with the custom title
+- 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
+- Fix a critical bug preventing library synchronization with Plex sign ins performed with `v0.0.22` or `v0.0.23`
+    - **If you are unable to sync libraries from Plex, please sign out and back in to apply this fix**
+- Fallback to `folder.jpg` when `poster.jpg` is not present
+- Attach episodes to correct show when adding NFO metadata to existing libraries
+
+## [0.0.23-prealpha] - 2021-03-21
+- Remove all Plex items from search index after sign out
+- Fix fallback metadata for local episodes (episode number was missing)
+- Improve television show year detection where year is missing from nfo metadata
+- Fix sorting for titles that start with `A` or `An` in addition to `The`
+- Properly escape search links containing special characters (genre, tag)
+- Add and index `Studio` metadata
+
+## [0.0.22-prealpha] - 2021-03-20
+- Log errors encountered during search index build; attempt to continue with partial index when errors are encountered
+- Only search `title` field by default; `genre` and `tag` can be searched with `field:query` syntax
+- Allow leading wildcards in searches
+- Keep search query in search field to allow easy modification
+- Fix default ffmpeg profile when creating new channels
+- Fix multiple bugs with updating Plex servers, libraries, path replacements
+- Add `release_date` to search index
+
+## [0.0.21-prealpha] - 2021-03-20
+- Optimize local library scanning to use less memory
+- Duplicate some documentation near the schedule item editor
+- Fix bug with updating `Normalize Video Codec` setting
+- Rework search functionality
+    - Search landing page will show up to 50 items of each type
+    - `See All` links can be used to page through all search results
+    - Complex search queries supported (`christmas OR santa`)
+    - Fields that are searched by default:
+        - `title`
+        - `genre`
+        - `tag`
+    - 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
+
+## [0.0.20-prealpha] - 2021-03-17
+- Fix NVIDIA hardware acceleration in `develop-nvidia` and `latest-nvidia` Docker tags
+    - This may never have worked correctly in Docker with older releases

+- Fix crash adding a channel when no channels exist
+- Fix playback for media containing attached pictures
+
