+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## [Unreleased]
+
+## [0.2.5-alpha] - 2021-11-21
+### Fixed
+- Include other video title in channel guide (xmltv)
+- Fix bug introduced with 0.2.4-alpha that caused some playouts to build from year 0
+- Use less memory matching Trakt list items
+
+### Added
+- Build osx-arm64 packages on release
+
+### Changed
+- No longer warn about local Plex guids; they aren't used for Trakt matching and can be ignored
+
+## [0.2.4-alpha] - 2021-11-13
+### Changed
+- Upgrade to dotnet 6
+- Use `scale_cuda` instead of `scale_npp` for NVIDIA scaling in all cases
+
+## [0.2.3-alpha] - 2021-11-03
+### Fixed
+- Fix bug with audio filter in cultures where `.` is a group/thousands separator
+- Fix bug where flood playout mode would only schedule one item
+  - This would happen if the flood was followed by another flood with a fixed start time
+
+### Added
+- Support empty `.etvignore` file to instruct local movie scanner to ignore the containing folder
+
+## [0.2.2-alpha] - 2021-10-30
+### Fixed
+- Fix EPG entries for Duration schedule items that play multiple items
+- Fix EPG entries for Multiple schedule items that play more than one item
+
+### Added
+- Add fallback filler settings to Channel and global FFmpeg Settings
+  - When streaming is attempted during an unscheduled gap, the resulting video will be determined using the following priority:
+    - Channel fallback filler
+    - Global fallback filler
+    - Generated `Channel Is Offline` error message video 
+
+### Changed
+- Allow per-episode folders for local show libraries
+  - e.g. `Show Name\Season #\Episode #\Show Name - s#e#.mkv`
+
+## [0.2.1-alpha] - 2021-10-24
+### Fixed
+- Fix saving dynamic start time on schedule items
+
+## [0.2.0-alpha] - 2021-10-23
+### Fixed
+- Fix generated streams with mpeg2video
+- Fix incorrect row count in playout detail table
+- Fix deleting movies that have been removed from Jellyfin and Emby
+- Fix bug that caused large unscheduled gaps in playouts
+  - This was caused by schedule items with a fixed start of midnight
+
+### Added
+- Add new filler system
+    - `Pre-Roll Filler` plays before each media item
+    - `Mid-Roll Filler` plays between media item chapters
+    - `Post-Roll Filler` plays after each media item
+    - `Tail Filler` plays after all media items, until the next media item
+    - `Fallback Filler` loops instead of default offline image to fill any remaining gaps
+- Store chapter details with media statistics; this is needed to support mid-roll filler
+    - This requires re-ingesting statistics for all media items the first time this version is launched
+- Add switch to show/hide filler in playout detail table
+- Add `minutes` field to search index
+  - This requires rebuilding the search index and search results may be empty or incomplete until the rebuild is complete
+
+### Changed
+- Change some debug log messages to info so they show by default again
+- Remove tail collection options from `Duration` playout mode
+- Show localized start time in schedule items tables
+
+## [0.1.5-alpha] - 2021-10-18
+### Fixed
+- Fix double scheduling; this could happen if the app was shutdown during a playout build
+- Fix updating Jellyfin and Emby TV seasons
+- Fix updating Jellyfin and Emby artwork
+- Fix Plex, Jellyfin, Emby worker crash attempting to sync library that no longer exists
+- Fix bug with `Duration` mode scheduling when media items are too long to fit in the requested duration
+
+### Added
+- Include music video thumbnails in channel guide (xmltv)
+
+### Changed
+- Automatically find working Plex address on startup
+- Automatically select schedule item in schedules that contain only one item
+- Change default log level from `Debug` to `Information`
+  - The `Debug` log level can be enabled in the `appsettings.json` file for non-docker installs
+  - The `Debug` log level can be enabled by setting the environment variable `Serilog:MinimumLevel=Debug` for docker installs
+
+## [0.1.4-alpha] - 2021-10-14
+### Fixed
+- Fix error message/offline stream continuity with channels that use HLS Segmenter
+- Fix removing items from search index when folders are removed from local libraries
+
+### Added
+- Add `Other Video` local libraries
+  - Other video items require no metadata or particular folder layout, and will have tags added for each containing folder
+  - For Example, a video at `commercials/sd/1990/whatever.mkv` will have the tags `commercials`, `sd` and `1990`, and the title `whatever`
+- Add filler `Tail Mode` option to `Duration` playout mode (in addition to existing `Offline` option)
+  - Filler collection will always be randomized (to fill as much time as possible)
+  - Filler will be hidden from channel guide, but visible in playout details in ErsatzTV
+  - Unfilled time will show offline image
+- Add `Guide Mode` option to all schedule items
+  - `Normal` guide mode will show all scheduled items in the channel guide (xmltv)
+  - `Filler` guide mode will hide all scheduled items from the channel guide, and extend the end time for the previous item in the guide
+
+## [0.1.3-alpha] - 2021-10-13
+### Fixed
+- Fix startup bug for some docker installations
+
+## [0.1.2-alpha] - 2021-10-12
+### Added
+- Include more cuda (nvidia) filters in docker image
+- Enable deinterlacing with nvidia using new `yadif_cuda` filter
+- Add two HLS Segmenter settings: idle timeout and work-ahead limit
+  - `HLS Segmenter Idle Timeout` - the number of seconds to keep transcoding a channel while no requests have been received from any client
+    - This setting must be greater than or equal to 30 (seconds)
+  - `Work-Ahead HLS Segmenter Limit` - the number of segmenters (channels) that will work-ahead simultaneously (if multiple channels are being watched)
+    - "working ahead" means transcoding at full speed, which can take a lot of resources
+    - This setting must be greater than or equal to 0
+- Add more watermark locations ("middle" of each side)
+- Add `VAAPI Device` setting to ffmpeg profile to support installations with multiple video cards
+- Add *experimental* `RadeonSI` option for `VAAPI Driver` and include mesa drivers in vaapi docker image
+
+### Changed
+- Upgrade ffmpeg from 4.3 to 4.4 in all docker images
+  - Upgrading from 4.3 to 4.4 is recommended for all installations
+- Move `VAAPI Driver` from settings page to ffmpeg profile to support installations with multiple video cards
+
+### Fixed
+- Fix some transcoding edge cases with nvidia and pixel format `yuv420p10le`
+
+## [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
