 ## [Unreleased]

+## [0.8.4-beta] - 2023-12-02
+### Fixed
+- Fix playout builder crash with improperly configured pad filler preset
+- Properly validate filler preset mode pad to require `filler pad to nearest minute` value
+- Fix bug where previously-synchronized collection tags would disappear
+  - This bug affected Jellyfin, Emby and Plex collections
+- Fix detection of AMF hardware acceleration on Windows 
+
+## [0.8.3-beta] - 2023-11-22
+### Added
+- Add `Scaling Behavior` option to FFmpeg Profile
+  - `Scale and Pad`: the default behavior and will maintain aspect ratio of all content
+  - `Stretch`: a new mode that will NOT maintain aspect ratio when normalizing source content to the desired resolution
+  - `Crop`: a new mode that will scale beyond the desired resolution (maintaining aspect ratio), and crop to desired resolution
+    - **This mode does NOT detect black and intelligently crop**
+    - The goal is to fill the canvas by over-scaling and cropping, instead of minimally scaling and padding
+- Include `inputstream.ffmpegdirect` properties in channels.m3u when requested by Kodi
+- Log playout item title and path when starting a stream
+  - This will help with media server libraries where the URL passed to ffmpeg doesn't indicate which file is streaming
+- Add QSV Capabilities to Troubleshooting page
+- Add `language_tag` and `seconds` fields to search index
+- Allow synchronizing Plex `TV Show` libraries that use `Personal Media Shows` agent
+- Include Noto CJK Fonts in docker images to support those characters in generated subtitles like songs and music video credits
+- Support show fallback metadata with folder names like `Show.Name(1992)`
+
+### Fixed
+- Fix playout bug that caused some schedule items with fixed start times to be pushed to the next day
+- Fix playout bug that prevented padded durations from fitting within a schedule item of the same duration
+  - For example, filler that padded to 30 minutes would often not fit in a 30 minute duration schedule item
+- Fix VAAPI transcoding 8-bit source content to 10-bit
+- Fix NVIDIA subtitle scaling when `scale_npp` filter is unavailable
+- Remove ffmpeg and ffprobe as required dependencies for scanning media server libraries
+  - Note that ffmpeg is still *always* required for playback to work
+- Fix PGS subtitle pixel format with Intel VAAPI
+- Fix some cases where `Copy` button would fail to copy to clipboard
+- Fix some cases where ffmpeg process would remain running after properly closing ErsatzTV
+- Fix QSV HLS segment duration
+  - This behavior caused extremely slow QSV stream starts
+- Fix displaying multiple languages in UI for movies, artists, shows
+- Fix MySQL queries that could fail during media server library scans
+- Fix scanning Jellyfin libraries when library options and/or path infos are not returned from Jellyfin API
+- Fix error indexing music videos in `File Not Found` state
+- Fix bug scheduling duration filler when filler collection contains item with zero duration
+- Fix bug displaying television seasons for shows that have no year metadata
+
+### Changed
+- Upgrade ffmpeg to 6.1, which is now *required* for all installs
+- Use new ffmpeg throttling method to minimize cpu/gpu use without impacting audio normalization
+- Change FFmpeg Profile `Normalize Loudness` setting from checkbox to dropdown
+  - `Off`: do not normalize loudness
+  - `loudnorm`: use `loudnorm` filter to normalize loudness (generally higher CPU use)
+  - `dynaudnorm`: use `dynaudnorm` filter to normalize loudness (generally lower CPU use)
+- Jellyfin collection scanning will no longer happen after every (automatic or forced) library scan
+    - Automatic/periodic scans will check collections one time after all libraries have been scanned
+    - There is a new table in the `Media` > `Libraries` page with a button to manually re-scan Jellyfin collections as needed
+- In FFmpeg Profile editor, only display hardware acceleration kinds that are supported by the configured ffmpeg
+- Test QSV acceleration if configured, and fallback to software mode if test fails
+- Detect QSV capabilities on Linux (supported decoders, encoders)
+- Use hardware acceleration for error messages/offline messages
+- Try to parse season number from season folder when Jellyfin does not provide season number
+  - This *may* fix issues where Jellyfin libraries show all season numbers as 0 (specials)
+- Rework Plex collection scanning
+    - Automatic/periodic scans will check collections one time after all libraries have been scanned
+    - There is a table in the `Media` > `Libraries` page with a button to manually re-scan Plex collections as needed
+    - Plex smart collections will now be synchronized as tags, similar to other Plex collections
+
+## [0.8.2-beta] - 2023-09-14
+### Added
+- Automatically rebuild search index after improper shutdown
+- Add *experimental* support for Elasticsearch as search index backend
+  - No query changes should be needed since ES is backed by lucene and supports the same query syntax
+  - This can be configured using the following env vars (note the double underscore separator `__`)
+    - `ELASTICSEARCH__URI` (e.g. `http://localhost:9200`)
+    - `ELASTICSEARCH__INDEXNAME` (default is `ersatztv`)
+- Add *experimental* support for MySQL/MariaDB database provider
+  - ***There is no functionality to migrate data between providers***
+  - This can be configured using the following env vars (note the double underscore separator `__`)
+    - `PROVIDER` - set to `MySql`
+    - `MYSQL__CONNECTIONSTRING` - (e.g. `Server=localhost;Database=ErsatzTV;Uid=root;Pwd=ersatztv;`)
+- Add option to use shared Plex servers, not just owned servers
+  - This can be enabled by setting the env var `ETV_ALLOW_SHARED_PLEX_SERVERS` to any non-empty value
+- Show Plex server names in Libraries page
+
+### Fixed
+- Fix subtitle scaling when using QSV hardware acceleration
+- Fix log viewer crash when log file contains invalid data
+- Clean channel guide cache on startup (delete channels that no longer exist)
+- Fix Emby movie libraries so local file access is not required
+- Fix adding alternate schedule
+- Fix parsing show title from NFO file that also contains season information
+
+### Changed
+- Optimize transcoding session to only work ahead (at max speed) for 3 minutes before throttling to realtime
+  - This should *greatly* reduce cpu/gpu use when joining a channel, particularly with long content
+- Allow manually editing (typing) schedule item fixed start time
+- Use different control for editing schedule item duration, and allow 24-hour duration
+  - This is needed if you want a default/fallback alternate schedule to fill the entire day with one schedule item
+  - The schedule item should have a fixed start time of midnight (00:00) and a duration of 24 hours
+- Use Direct3D 11 for QSV acceleration on Windows
+
+## [0.8.1-beta] - 2023-08-07
+### Added
+- Add custom resolution management to `Settings` page
+
+### Fixed
+- Only allow a single instance of ErsatzTV to run
+  - This fixes some cases where the search index would become unusable
+- Fix VAAPI rate control mode capability check 
+
+### Changed
+- Rework startup process to show UI as early as possible
+  - A minimal UI will indicate when the database and search index are initializing
+  - The UI will automatically refresh when the initialization processes have completed
+- Force ffmpeg to use one thread when hardware acceleration is used since hardware acceleration does not support multiple threads
+
+## [0.8.0-beta] - 2023-06-23
+### Added
+- Disable playout buttons and show spinning indicator when a playout is being modified (built/extended, or subtitles are being extracted)
+- Automatically reload playout details table when playout build is complete
+- Add `Discard To Fill Attempts` setting to duration playout mode
+  - This setting only has an effect when it's configured to be greater than zero and when using `Shuffle` or `Random` playback order
+  - When the current item is longer than the remaining duration, it will be discarded and ETV will try to fit the next item in the collection, up to the configured number of times
+  - When the remaining duration is shorter than all items in the collection, the normal filler logic will be used
+- Add `Finish` column to playout detail table
+
+### Fixed
+- Skip checking for subtitles to extract when subtitles are not enabled on a channel/schedule item
+- Properly scale subtitles when using hardware acceleration
+- Fix color normalization of content with missing color metadata when using NVIDIA acceleration
+- `VAAPI`: explicitly use `CQP` rate control mode when it's the only compatible mode
+- Fix scaling anamorphic Emby content that Emby claims is not anamorphic
+
+### Changed
+- `HLS Direct` streaming mode
+    - Use `MPEG-TS` container/output format by default to maintain v0.7.8 compatibility
+      - `MP4` and `MKV` container/output format can still be configured in `Settings`
+    - Improve `MP4` compatibility with certain content
+- For `Pad` and `Duration` filler - prioritize filling the configured pad/duration
+  - This will skip filler that is too long in an attempt to avoid unscheduled time
+  - You may see the same filler more often, which means you may want to add more filler to your library so ETV has more options
+- Update ffmpeg, libraries and drivers in all docker images
+
+## [0.7.9-beta] - 2023-06-10
+### Added
+- Synchronize actor metadata from Jellyfin and Emby television libraries
+  - New libraries and new episodes will get actor data automatically
+  - Existing libraries can deep scan (one time) to retrieve actor data for existing episodes
+- `HLS Direct` streaming mode
+    - Use `MP4` container/output format by default, with new global option to use `MKV` container/output format
+    - `MP4` output format: stream copy dvd subtitles
+    - `MKV` output format: stream copy any embedded subtitles
+
+### Fixed
+- Fix extracting embedded text subtitles that had been incompletely extracted in the past 
+- Fix fallback filler looping by forcing software mode for this content
+  - Other content will still use hardware acceleration as configured
+  - Hardware-accelerated fallback filler may be re-enabled in the future
+- Fix playout building when shuffle in order is used with a single media item
+- Fix pgs subtitle burn in from media server libraries
+- Fix subtitle and watermark overlays with RadeonSI VAAPI driver
+- Fix NVIDIA pipeline to use hardware-accelerated decoder with 8-bit h264 content   
+
+### Changed
+- Timeout playout builds after 2 minutes; this should prevent playout bugs from blocking other functionality
+
+## [0.7.8-beta] - 2023-04-29
+### Added
+- Add `Season, Episode` playback order
+  - This is currently *only* available when a show is added directly to a schedule
+  - This will ignore release date and sort exclusively by season number and then by episode number
+- Add `Show Media Info` button to movie and episode detail pages for troubleshooting
+
+### Fixed
+- Limit `HLS Direct` streams to realtime speed
+- Fix `Reset Playout` button to use worker thread instead of UI thread
+  - This fixes potential UI hangs and database concurrency bugs
+- Maintain watermark alpha channel (built-in transparency) using QSV acceleration
+- Properly extract and burn in embedded text subtitles using Jellyfin, Emby and Plex libraries
+- Fix bug where deleting a channel would not remove its data from XMLTV
+- Fix colorspace filter for some files with invalid color metadata
+- Fix playback of external subtitles on Windows
+- Fix vobsub subtitle burn in from media server libraries
+
+### Changed
+- Remove duplicate items from smart collections before scheduling
+  - i.e. shows no longer need to be filtered out if search results also include episodes
+  - Certain multi-collection scenarios may still include duplicates across multiple collections
+- Use autocomplete fields for collection searching in schedule items editor
+  - This greatly improves the editor performance
+- Ignore dot underscore files
+
+## [0.7.7-beta] - 2023-04-07
+### Added
+- Use `plot` field from Other Video NFO metadata as XMLTV description
+- Add detailed warning log when a file is added to ErsatzTV more than once
+
+### Fixed
+- Fix updating (re-adding) Trakt lists to properly use new metadata ids that were not present when originally added
+- Fix local show library scanning with non-english season folder names, e.g. `Staffel 02`
+- Fix bug where local libraries would merge with media server libraries when the same file was added to both libraries
+- Fix transcoding some 10-bit content from media servers using VAAPI acceleration
+- Fix decoding of MPEG-4 Part 2 (e.g. DivX) content using NVIDIA acceleration
+- Fix color normalization from `bt470bg` to `bt709` using QSV acceleration
+- Fix adding files to search index with unknown video codec
+- Fix subtitle burn-in (embedded or external) using Jellyfin, Emby and Plex libraries
+    - **This requires a one-time full library scan, which may take a long time with large libraries.**
+
+### Changed
+- Use Poster artwork for XMLTV if available
+  - If Poster artwork is unavailable, use Thumbnail
+- Improve XMLTV response time by caching data as playouts are updated 
+
+## [0.7.6-beta] - 2023-03-24
+### Added
+- Add `Troubleshooting` page with aggregated settings/hardware accel info for easy reference
+- Read `director` fields from music video NFO metadata
+- Pass `directors` and `studios` to music video credit templates
+- Add optional JSON Web Token (JWT) query string auth for streaming endpoints (everything under `/iptv`)
+  - This can be configured using the following env var (note the double underscore separator `__`)
+    - `JWT__ISSUERSIGNINGKEY`
+  - When configured, a JWT signed with the configured signing key is required to be passed in the query string as `access_token`, for example:
+    - `http://localhost:8409/iptv/channels.m3u?access_token=ABCDEF`
+    - `http://localhost:8409/iptv/xmltv.xml?access_token=ABCDEF`
+  - When channels are retrieved this way, the access token will automatically be passed through to all necessary urls
+  - Note that ONLY the `/iptv` endpoints will require auth when JWT is configured
+
+### Fixed
+- Fix scaling anamorphic content from non-local libraries
+- Fix direct streaming content from Jellyfin that has external subtitles
+  - Note that these subtitles are not currently supported in ETV, but they did cause a playback issue
+- Fix Jellyfin, Emby and Plex library scans that wouldn't work in certain timezones
+- Fix song normalization to match FFmpeg Profile bit depth
+- Fix bug playing some external subtitle files (e.g. with an apostrophe in the file name)
+- Fix bug detecting VAAPI capabilities when no device is selected in active FFmpeg Profile
+- Fix playout mode duration bugs in XMLTV
+  - Tail mode filler will properly include filler duration in XMLTV
+  - Duration that wraps across midnight will no longer have overlapping items in XMLTV
+- Maintain collection progress across all alternate schedules on a playout
+- Fix color normalization from `bt470bg` to `bt709`
+
+### Changed
+- Ignore case of video and audio file extensions in local folder scanner
+  - For example, the scanner will now find `movie.MKV` as well as `movie.mkv` on case-sensitive filesystems
+- Include multiple `display-name` entries in generated XMLTV
+  - Plex should now display the channel number instead of the channel id (e.g. `1.2` instead of `1.2.etv`)
+- Rework concurrency a bit
+  - Playout builds are no longer blocked by library scans
+  - Adding Trakt lists is no longer blocked by library scans
+  - All library scans (local and media servers) run sequentially
+- Emby collection scanning will no longer happen after every (automatic or forced) library scan
+  - Automatic/periodic scans will check collections one time after all libraries have been scanned
+  - There is a new table in the `Media` > `Libraries` page with a button to manually re-scan Emby collections as needed
+- For performance reasons, limit console log output to errors on Windows
+  - Other platforms are unchanged
+  - Log file behavior is unchanged
+
 ## [0.7.5-beta] - 2023-03-05
 ### Added
