 ## [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 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
+- Use AV1 hardware-accelerated decoder with VAAPI, QSV, NVIDIA when available
+- Use VP9 hardware-accelerated decoder with VAAPI when available
+
+### Fixed
+- Align default docker image (no acceleration) with new images from [ErsatzTV-ffmpeg](https://github.com/ErsatzTV/ErsatzTV-ffmpeg)

+- Improve VAAPI encoder capability detection on newer hardware
+- Fix trash page to properly display episodes with missing metadata or titles
+- Fix playback of content with yuv444p10le pixel format
+- Fix case where some multi-episode files from Plex would crash the scanner
+
+### Changed
+- Upgrade all docker images and windows builds to ffmpeg 6.0
+- Plex, Jellyfin and Emby libraries now retrieve all metadata and statistics from the media server
+  - File systems will no longer be periodically scanned for libraries using these media sources
+- Plex, Jellyfin and Emby libraries now direct stream content when files are not found on ErsatzTV's file system
+  - Content will still be normalized according to the Channel and FFmpeg Profile settings
+  - Streaming from disk is preferred, so every playback attempt will first check the local file system
+- Use libvpl instead of libmfx to provide intel acceleration in vaapi docker images
+- Search queries no longer remove duplicate results as this was causing incorrect behavior
+- Prioritize audio streams that are flagged as "default" over number of audio channels
+    - For example, a video with a stereo commentary track and a mono "default" track will now prefer the "default" track
+- Support many more season folder names with local television libraries
+
+## [0.7.4-beta] - 2023-02-12
+### Added
+- Add button to copy/clone schedule from schedules table
+- Synchronize episode tags and genres from Jellyfin, Emby and Local show libraries
+- Add `Deep Scan` button to Jellyfin and Emby libraries
+  - This is now required to update some metadata for existing libraries, when targeted updates are not possible
+  - For example, if you already have tags and genres on your episodes in Jellyfin or Emby, you will need to deep scan each library to update that metadata on existing items in ErsatzTV
+
+### Fixed
+- Fix many QSV pipeline bugs
+- Fix MPEG2 video format with QSV and VAAPI acceleration
+- Fix playback of content with undefined colorspace
+- Fix NVIDIA color normalization with VP9 sources
+- Fix fallback filler looping
+- Fix bug where some libraries would never scan
+- Fix filler ordering so post-roll is properly scheduled after padded mid-roll
+- Fix pre/post-roll filler padding when used with mid-roll
+  - This caused overlapping schedule items, fallback filler that was too long, etc.
+
+### Changed
+- Merge generated `Other Video` folder tags with tags from sidecar NFO
+- Prioritize audio streams that are flagged as "default" when multiple candidate streams are available
+  - For example, a video with a stereo commentary track and a stereo "default" track will now prefer the "default" track 
+
+## [0.7.3-beta] - 2023-01-25
+### Added
+- Attempt to release memory periodically
+- Add OpenID Connect (OIDC) support (e.g. Keycloak, Authelia, Auth0)
+  - This only protects the management UI; all streaming endpoints will continue to allow anonymous access 
+  - This can be configured with the following env vars (note the double underscore separator `__`)
+    - `OIDC__AUTHORITY`
+    - `OIDC__CLIENTID`
+    - `OIDC__CLIENTSECRET`
+    - `OIDC__LOGOUTURI` (optional, needed for Auth0, use `https://{auth0-domain}/v2/logout?client_id={auth0-client-id}` with proper values for domain and client-id)
+- Add *experimental* alternate schedule system
+  - This allows a single playout to dynamically select a schedule based on date criteria, for example:
+    - Weekday vs weekend schedules
+    - Summer vs fall schedules
+    - Shark week schedules
+  - Alternate schedules can be managed by clicking the calendar icon in the playout list
+  - Playouts contain a prioritized (top to bottom) list of alternate schedules
+  - Whenever a playout is built for a given day, ErsatzTV will check for a matching schedule from top to bottom
+  - A given day must match all alternate schedule parameters; wildcards (`*any*`) will always match
+    - Day of week
+    - Day of month
+    - Month
+  - The lowest priority (bottom) item will always match all parameters, and can be considered a "default" or "fallback" schedule 
+
+### Fixed
+- Fix schedule editor crashing due to bad music video artist data
+- Fix bug where playouts would not maintain smart collection progress on schedules that use multiple smart collections
+- Fix library scanning on osx-arm64
+- Fix ability to remove some media server libraries from ErsatzTV
+
+### Changed
+- Always use software pipeline for error display
+  - This ensures errors will display even when hardware acceleration is misconfigured
+- Call scanner process only when scanning is required based on library refresh interval
+- Use lower process priority for scanner process with unforced (automatic) library scans
+- Disable V2 UI and APIs by default
+  - V2 UI can be re-enabled by setting the env var `ETV_UI_V2` to any value
+
+## [0.7.2-beta] - 2023-01-05
+### Fixed
+- Fix VAAPI encoding in docker by switching to non-free driver
+
+### Changed
+- Rewrite log page to read directly from log files instead of sqlite
+
+## [0.7.1-beta] - 2023-01-03
+### Added
+- Add new music video credit templates
+
+### Fixed
+- Fix many transcoding failures caused by the colorspace filter
+- Fix song playback with VAAPI and NVENC
+- Fix edge case where some local movies would not automatically be restored from trash
+- Fix synchronizing Jellyfin and Emby collection items
+- Fix saving some external subtitle records to database 
+
+### Changed
+- Upgrade to dotnet 7
+- Upgrade all docker images to ubuntu jammy and ffmpeg 5.1.2
+- Limit library scan interval between 0 and 1,000,000
+  - 0 means do not automatically scan libraries
+  - 1 to 999,999 means scan if it has been that many hours since the last scan
+- Use new `ErsatzTV.Scanner` process for scanning all libraries
+  - This should reduce the ongoing memory footprint
+
+## [0.7.0-beta] - 2022-12-11
+### Fixed
+- Fix removing Jellyfin and Emby libraries that have been deleted from the source media server
+- Fix `Work-Ahead HLS Segmenter Limit` setting to properly limit number of channels that can work-ahead at once
+- Include base path value in generated channel playlist (M3U) and channel guide (XMLTV) links
+- Fix parsing song metadata from OGG audio files
+- Properly unlock/re-enable trakt list operations after an operation is canceled
+
+### Added
+- Add (required) bit depth normalization option to ffmpeg profile
+  - This can help if your card only supports e.g. h264 encoding, normalizing to 8 bits will allow the hardware encoder to be used
+- Extract font attachments after extracting text subtitles
+  - This should improve SubStation Alpha subtitle rendering
+- Detect VAAPI capabilities and fallback to software decoding/encoding as needed
+- Add audio stream selector scripts for episodes and movies
+  - This will let you customize which audio stream is selected for playback
+  - Episodes are passed the following data:
+    - `channelNumber`
+    - `channelName`
+    - `showTitle`
+    - `showGuids`: array of string ids like `imdb_1234` or `tvdb_1234`
+    - `seasonNumber`
+    - `episodeNumber`
+    - `episodeGuids`: array of string ids like `imdb_1234` or `tvdb_1234`
+    - `preferredLanguageCodes`: array of string preferred language codes configured for the channel
+    - `audioStreams`: array of audio stream data, each containing
+      - `index`: the stream's index number, this is what the function needs to return
+      - `channels`: the number of audio channels
+      - `codec`: the audio codec
+      - `isDefault`: bool indicating whether the stream is flagged as default
+      - `isForced`: bool indicating whether the stream is flagged as forced
+      - `language`: the stream's language
+      - `title`: the stream's title
+  - Movies are passed the following data:
+      - `channelNumber`
+      - `channelName`
+      - `title`
+      - `guids`: array of string ids like `imdb_1234` or `tvdb_1234`
+    - `preferredLanguageCodes`: array of string preferred language codes configured for the channel
+    - `audioStreams`: array of audio stream data, each containing
+        - `index`: the stream's index number, this is what the function needs to return
+        - `channels`: the number of audio channels
+        - `codec`: the audio codec
+        - `isDefault`: bool indicating whether the stream is flagged as default
+        - `isForced`: bool indicating whether the stream is flagged as forced
+        - `language`: the stream's language
+        - `title`: the stream's title
+- Add new fields to search index
+  - `video_codec`: the video codec
+  - `video_bit_depth`: the number of bits in the video stream's pixel format, e.g. 8 or 10
+  - `video_dynamic_range`: the video's dynamic range, either `sdr` or `hdr`
+
+### Changed
+- Change `Multi-Episode Shuffle` scripting system to use Javascript instead of Lua
+
+## [0.6.9-beta] - 2022-10-21
+### Fixed
+- Fix bug where tail or fallback filler would sometimes schedule much longer than expected
+  - This only happened with fixed start schedule items following a schedule item with tail or fallback filler
+- Fix NFO reader bug that caused inaccurate warning messages about invalid XML and incomplete metadata
+- Fix reverse proxy SSL termination support by supporting `X-Forwarded-Proto` header
+- Fix automatic playout reset scheduling
+  - Playouts would reset every 30 minutes between midnight and the configured time, instead of only at the configured time
+- XMLTV: properly group schedule items with `Custom Title` followed by item(s) with `Guide Mode` set to `Filler`
+
+### Added
+- Add music video credits template system
+  - Templates are selected in each channel's settings 
+  - Templates should be copied from `_default.ass.sbntxt` which is located in the config subfolder `templates/music-video-credits`
+    - Copy the file, give it any name ending with `.ass.sbntext`, and only make edits to the copied file
+  - The default template will be extracted and overwritten every time ErsatzTV is started
+  - The template is an [Advanced SubStation Alpha](http://www.tcax.org/docs/ass-specs.htm) file using [scribian](https://github.com/scriban/scriban/tree/master/doc) template syntax
+  - The following fields are available for use in the template:
+    - `resolution`: the ffmpeg profile's resolution, which is used for margin calculations
+    - `title`: the title of the music video
+    - `track`: the music video's track number
+    - `album`: the music video's album
+    - `plot`: the music video's plot
+    - `release_date`: the music video's release date
+    - `artist`: the music videos artist (the parent folder)
+    - `all_artists`: a list of additional artists from the music video's sidecar NFO metadata file
+    - `duration`: the timespan duration of the music video, which can be used to calculate timing of additional subtitles
+    - `stream_seek`: the timespan that ffmpeg will seek into the media item before beginning playback
+- Add `Multi-Episode Shuffle` playout order for `Television Show` schedule items
+  - The purpose of this playout order is to improve randomization for shows that normally have intro, multiple episodes, and outro
+  - This playout order requires splitting the parts into individual files (e.g. splitting `s01e01-03.mkv` into `s01e01.mkv`, `s01e02.mkv` and `s01e03.mkv`)
+  - This playout order requires a lua script in the config subfolder `scripts/multi-episode-shuffle`
+  - The lua script should be named for the television show's guid, e.g. `tvdb_12345.lua` or `imdb_tt123456789.lua`
+  - The script defines the number of parts that each un-split file typically contains
+  - The script also defines a function to map each episode to a part number (or no part number i.e. `nil` if an episode has not been split)
+  - All groups of part numbers (i.e. all part 1s, all part 2s) will be shuffled
+  - The playout order will then schedule a random part 1 followed by a random part 2, etc
+    - Un-split (`nil`) episodes will be randomly placed between re-combined parts (e.g. part1, part2, part3, un-split, part1, part2, part3)
+- Add `ETV_BASE_URL` environment variable to support reverse proxies that use paths (e.g. `/ersatztv`)
+
+### Changed
+- No longer place watermarks within content by default (e.g. within 4:3 content padded to a 16:9 resolution)
+  - This can be re-enabled if desired using the `Place Within Source Content` checkbox in watermark settings
+
+## [0.6.8-beta] - 2022-10-05
+### Fixed
+- Fix typo introduced in `0.6.7-beta` that stopped QSV HEVC encoder from working
+- Fix scaling logic for `Nvidia` acceleration and software mode
+- Attempt to position watermarks within content (not over added black padding)
+- Fix search results for `Other Videos` when NFO metadata is used
+- Properly synchronize tags from Emby movies and shows
+- Properly sync updated file paths from Plex
+- Fix numeric range search queries (e.g. `minutes:[5 TO 10]`, `minutes:[* TO 3]`)
+
+### Added
+- Add `QSV Device` option to ffmpeg profile on linux
+- Add guids to search index (e.g. `imdb:tt000000`, `tvdb:12345`)
+
+## [0.6.7-beta] - 2022-09-05
+### Fixed
+- When all audio streams are selected with `HLS Direct`, explicitly copy them without transcoding
+  - This only happens when the channel does not have a `Preferred Audio Language`
+- Fix scanner crash caused by invalid mtime
+- `VAAPI`: Downgrade libva from 2.15 to 2.14
+- Fix bug with XMLTV that caused some filler to display with primary content details
+- Multiple fixes for content scaling with `Nvidia`, `Qsv` and `Vaapi` accelerations
+- Properly scale image-based subtitles
+- Fix bug where a schedule containing a single item (fixed start and flood) would never finish building a playout
+  - Logic was also added to detect infinite playout build loops in the future and stop them
+- Fix bug where `Other Videos` wouldn't be included in scheduling mode `Shuffle In Order`
+
+### Added
+- Add `Preferred Audio Title` feature
+    - Preference can be configured in channel settings and overridden on schedule items
+    - When a title is specified, audio streams that contain that title (case-insensitive search) will be prioritized
+    - This can be helpful for creating channels that use commentary tracks
+    - External tooling exists to easily update title/name metadata if your audio streams don't already have this metadata
+- Add `Amf` hardware acceleration option for AMD GPUs on Windows
+- Add `QSV Extra Hardware Frames` parameter for tuning QSV acceleration
+  - Performance may improve on some systems after doubling or halving the default value of `64`
+
+## [0.6.6-beta] - 2022-08-17
+### Fixed
+- Use MIME Type `application/x-mpegurl` for all playlists instead of `application/vnd.apple.mpegurl`
+- Replace `setsar` filter with `setdar` filter
+  - `setsar` caused issues scaling between two different aspect ratios
+    - For example, some 4:3 content would appear stretched when scaled to a 16:9 resolution
+  - `setdar` is now only used when aspect ratios match 
+- Prioritize aspect ratio from container when video stream contains conflicting aspect ratio
+  - This is usually caused by bad authoring, but the change should improve scaling behavior for edge cases
+
+### Added
+- Support DSD audio file formats (DFF and DSF) in local song libraries
+- Support OGG audio file formats (OGG, OPUS, OGA, OGX, SPX) in local song libraries
+
+### Changed
+- Always return playlist after a maximum of 8 seconds while starting up an HLS Segmenter session
+- Use multi-variant playlists instead of redirects for HLS Segmenter sessions
+- Upgrade ffmpeg from 5.0 to 5.1 in most docker images (not ARM variants)
+    - Upgrading from 5.0 to 5.1 is also recommended for other installations (Windows, Linux)
+
+## [0.6.5-beta] - 2022-08-02
+### Fixed
+- Fix database initializer; fresh installs with v0.6.4-beta are missing some config data and should upgrade
+
+## [0.6.4-beta] - 2022-07-28
+### Fixed
+- Fix subtitle stream selection when subtitle language is different than audio language
+- Fix bug with unsupported AAC channel layouts
+- Fix NVIDIA second-gen maxwell capabilities detection
+- Return distinct search results for episodes and other videos that have the same title
+  - For example, two other videos both named `Trailer` would previously have displayed as one item in search results
+- Fix schedules that would begin to repeat the same content in the same order after a couple of days
+
+### Added
+- Add `640x480` resolution
+
 ## [0.6.3-beta] - 2022-07-04
 ### Fixed
 - Maintain stream continuity when playout is rebuilt for a channel that is actively being streamed
@@ -1264,103 +1807,125 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
