 ## [Unreleased]
 
-## [25.7.0] - 2025-09-14
+## [25.9.0] - 2025-11-29
+### Added
+- Show playout warnings count badge in left menu
+- Graphics Engine:
+  - Add `MediaItem_Resolution` template data (the current `Resolution` variable is the FFmpeg Profile resolution)
+  - Add `MediaItem_Start` template data (DateTimeOffset)
+  - Add `MediaItem_Stop` template data (DateTimeOffset)
+  - Add `ScaledResolution` template data (the final size of the frame before padding)
+  - Add `place_within_source_content` (true/false) field to image graphics element
+  - Add `name` field to all graphics elements to display in the UI
+- Classic and block schedules: add collection type `Search Query`
+  - This allows defining search queries directly on schedule items without creating smart collections beforehand
+  - As an example, this can be used to filter or combine existing smart collections
+    - Filter: `smart_collection:"sd movies" AND plot:"christmas"`
+    - Combine: `smart_collection:"old commercials" OR smart_collection:"nick promos"`
+- Scripted schedules: add `custom_title` to `start_epg_group`
+- Add MPEG-TS Script system
+  - This allows using something other than ffmpeg (e.g. streamlink) to concatenate segments back together when using MPEG-TS streaming mode
+  - Scripts live in config / scripts / mpegts
+  - Each script gets its own subfolder which contains an `mpegts.yml` definition and corresponding windows (batch) and linux (bash) scripts
+  - The global MPEG-TS script can be configured in **Settings** > **FFmpeg** > **Default MPEG-TS Script**
+- Add `.avs` AviSynth Script support to all local libraries
+  - `.avs` was added as a valid extension, so they should behave the same any other video file
+  - There are two requirements for AviSynth Scripts to work:
+    - FFmpeg needs to be compiled with AviSynth support (not currently available in Docker)
+    - AviSynth itself needs to be installed
+- Add `Troubleshoot` button to classic schedule list
+  - This generates JSON representing the entire schedule which can be shared when requested for troubleshooting
+- Add **Settings** > **FFmpeg** > **Probe For Interlaced Frames**
+  - When enabled, this will probe *local content* for interlaced frames on demand (immediately before playback)
+  - This will be used as a more accurate check for interlaced content
+  - The result will be cached (only probed once and stored) in the database along with all other media item statistics (e.g. duration)
+  - This feature will currently ignore content that is not streamed from disk
+- Add error/offline background customization
+  - Default error background is now named `_background.png`
+  - Error streams will prioritize using `background.png` if it exists
+    - Replacing this `background.png` file will allow custom error/offline backgrounds
+- Add `Troubleshoot Playback` buttons on movie and episode detail pages
+- Add song background and missing album art customization
+  - Default files start with an underscore; custom versions must remove the underscore
+- Expose arbitrary EPG data to graphics engine via channel guide templates
+  - XML nodes using the `etv:` namespace will be passed to the graphics engine EPG template data
+  - For example, adding `<etv:episode_number_key>{{ episode_number }}</etv:episode_number_key>` to `episode.sbntxt` will also add the `episode_number_key` field to all EPG items in the graphics engine
+  - All values parsed from XMLTV will be available as strings in the graphics engine (not numbers)
+  - All `etv:` nodes will be stripped from the XMLTV data when requested by a client
+- Add channel troubleshooting button to channels list
+  - This will open the playback troubleshooting tool in "channel" mode
+  - This mode requires entering a date and time, and will play up to 30 seconds of *one item from that channel's playout* starting at the entered date and time
+- Block schedules: add copy template button to templates table
+
+### Fixed
+- Fix HLS Direct playback with Jellyfin 10.11
+- Fix remote stream scripts (parsing issue with spaces and quotes)
+- Fix block history being removed when it is still needed for mirror channel
+  - This caused playout build errors like "Unable to locate history for playout item"
+- Fix crashes due to invalid smart collection searches, e.g. `smart_collection:"this collection does not exist"`
+- Fix UI crash when editing block playout that has default deco
+- Fix playback failure when seeking content with certain DTS audio (e.g. DTS-HD MA)
+- Properly set explicit audio decoder on combined audio and video input file
+- Fix building sequential schedules across a UTC offset change
+- Fix block start time calculation across a UTC offset change
+- Fix classic schedule start time calculation across a UTC offset change
+- Fix XMLTV generation for channels using on-demand playout mode
+- Fix some file not found songs missing from trash view
+- Fix error/offline screen generation
+- Fix subtitle title sync from Jellyfin libraries
+  - Deep scans will be required to update subtitle titles on existing media items
+- Fix saving subtitle title changes to the database
+  - This fixes e.g. where stream selection would continue to use the original title
+  - This fix applies to all libraries (local and media server)
+- Fix (3 year old) bug removing tags from local libraries when they are removed from NFO files (all content types)
+  - New scans will properly remove old tags; NFO files may need to be touched to force updating during a scan
+- Fix bug where looping motion graphics wouldn't be displayed when seeking into second half of content
+- Fix `content_total_duration` value in graphics engine opacity expressions
+  - This bug caused some graphics elements to display too early after first joining a channel
+- Optimize database calls made for search index rebuilds and updates
+  - This should improve performance of library scans
+- Add toggle to hide/show disabled channels in channel list
+- Add disabled text color and `(D)` and `(H)` labels for disabled and hidden channels in channel list
+- Graphics engine: fix subtitle path escaping and font loading
+- Fix corrupt output (green artifacts) when decoding certain 10-bit content using AMD Polaris GPUs
+- Work around sequential schedule validation limit (1000/hr by Newtonsoft.Json.Schema library)
+  - Playout builds now use JsonSchema.Net library which has no validation limit
+  - Validation tool in the UI still uses Newtonsoft.Json.Schema (with 1000/hr limit) as the error output is easier to understand
+- Fix editing scripted and sequential playouts when using MySql
+- Fix HLS Direct streams remaining open after client disconnect
+- Always log scanner exit code when it is non-zero
+
+### Changed
+- Classic schedules: `Refresh` classic playouts from playout list; do not `Reset` them
+  - This mode maintains progress; progress can be reset by editing the playout and clicking `Erase Items and History`
+- Use smaller batch size for search index updates (100, down from 1000)
+  - This should help newly scanned items appear in the UI more quickly
+- Replace favicon and logo in background image used for error streams
+- Block schedules:
+  - Auto scroll day view to block item time when adding and removing block items from template
+  - Allow keyboard selection of
+    - Block groups in block list
+    - Template groups in template list
+    - Block groups and blocks in template editor
+  - Replace template tree view with searchable table (like blocks)
+- Upgrade to dotnet 10
+
+## [25.8.0] - 2025-10-26
+### Added
+- Graphics engine:
+  - Add template data (like `MediaItem_Title`) for other video files
+  - Add `MediaItem_Path` for movies, episodes, music videos and other videos
+  - Add `get_directory_name` and `get_filename_without_extension` functions for path processing
+  - Add `text_align` property to text graphics elements (values: `left`, `right` and `center`)
+  - Add `MiddleCenter` value to `location` property on all graphics elements
+    - Positive and negative margins can be used to offset from center as desired
+  - Add `line_height` property to text element style definition
+    - This is a multiplier that defaults to 1.0 when unspecified
+  - Add `halo_color`, `halo_width` and `halo_blur` properties to text element style definition
+    - These can be used to "outline" text with the configured color (e.g. `#000000`), width (e.g. `10`) and amount of blur (e.g. `2`)
+- Add `Block Playout Troubleshooting` tool to help investigate block playout history
+- Add sequential schedule file and scripted schedule file names to playouts table
+- Add empty (but already up-to-date) sqlite3 database to greatly speed up initial startup for fresh installs
+- Add button to copy/clone block from blocks table
+- Add playback speed to playback troubleshooting output
+  - Speed is relative to realtime (1.0x is realtime)
+  - Speeds < 0.9x will be colored red, between 0.9x and 1.1x colored yellow, and > 1.1x colored green
+- Add episode thumbnail artwork URL to XMLTV template
+  - By default, poster will be added as image with type "poster" and thumbnail will be added as image with type "still"
+  - Poster will continue to be added as icon by default
+- Add buttons to edit Jellyfin and Emby connection information in **Media Sources** > **Jellyfin** and **Media Sources** > **Emby**
+- Add audio format `aac (latm)` for DVB-C compatibility; `aac` uses ADTS by default which is required in most cases
+- Add deep scan option for external collections (Plex, Jellyfin, Emby)
+  - Jellyfin and Emby collection scans have always been deep scans
+  - Now, by default, they will be quick scans that trust Jellyfin and Emby's etags for detecting changes
+  - If a quick scan misses updating a collection, deep scans can be triggered manually
+
+### Fixed
+- Fix NVIDIA startup errors on arm64
+- Fix remote stream durations in playouts created using block, sequential or scripted schedules
+- Fix playback troubleshooting selecting a subtitle even with no subtitle stream selected in the UI
+- Fix intermittent watermark opacity
+- Improve reliability of live remote streams; they should transcode closer to realtime in most cases
+- Dramatically improve stream startup time
+- VAAPI: fix scaling image-based subtitles (e.g. dvdsub)
+- VAAPI: fix overlaying picture subtitles with scaling behavior crop
+- Fix HLS Segmenter (fmp4) on Windows
+- Playback troubleshooting: wait for at least 2 initial segments (up to configured initial segment count) to reduce stalls
+- Fix Trakt List sync
+- Fix QSV audio sync
+- Fix QSV capability detection on Linux using non-drm displays (e.g. wayland)
+- Fix playlist filtering bug that made HLS Segmenter more likely to fail when streaming for multiple hours
+- Fix NVIDIA overlaying text subtitles and permanent watermark on 10-bit content
+- Fix UI error adding deco
+- Fix UI error editing watermarks and graphics elements on blocks
+- Fix showing playout build failure details when resetting a playout
+- Fix scheduling auto-generated trakt list playlists that contain shows
+- Fix playout builder getting stuck (forever) on block item with an empty collection
+- Fix HLS Direct playback when using custom stream selector or preferred audio language/title
+- Fix selecting embedded subtitles (text and picture) with HLS Direct
+- Fix building scripted schedules across a UTC offset change
+
+### Changed
+- Do not use graphics engine for single, permanent watermark
+- Rename `YAML Validation` tool to `Sequential Schedule Validation`
+- Greatly reduce debug log spam during playout builds by logging summaries of certain warnings at the end
+- Remove *experimental* `HLS Segmenter V2` streaming mode; it is not possible to maintain quality output using this mode
+- Remove *experimental* `HLS Segmenter (fmp4)` streaming mode; this mode only worked properly in a browser, many clients did not like it
+- Change how scanner process and main process communicate, which should improve reliability of search index updates when scanning
+
+## [25.7.1] - 2025-10-09
+### Added
+- Add search field to filter blocks table
+- Show full error/exception details in playback troubleshooting logs
+- Add basic free space validation on startup
+  - ETV will now fail to start with less than 128 MB free space in config or transcode folders
+- Add downgrade health check to inform users when they are doing something that WILL impact stability
+
+### Fixed
+- Do not allow deleting ffmpeg profiles that are used by channels
+- Do not allow deleting default ffmpeg profile
+- Allow ffmpeg profiles using VAAPI accel to set h264 video profile
+- Fix HLS Direct playback, and make it accessible on separate streaming port
+- Fix playback troubleshooting when using multiple watermarks or multiple graphics elements
+
+### Changed
+- Use table instead of tree view on blocks page
+- Use different release packaging system to workaround false positive from Windows Defender
+
+## [25.7.0] - 2025-10-03
