REAPER

What's new in this version:

Video:
- add support for FFmpeg versions 5.0-8.1
- add FFmpeg support for ALAC decoding (s32p sample type)
- add FFmpeg support for AV1 encoding (if supported, preferring libsvtav1 over libaom-av1 for speed)
- add FFmpeg support for H.265 encoding (if supported)
- add FFmpeg support for hardware accelerated decoding, opt-in by using ffmpeg_hw in decoder list
- add FFmpeg support for multiple audio streams, opt-in by using ffmpeg_mta in video decoder list
- add FFmpeg support for arbitrary encoders, use codec=xyz in FFmpeg configuration
- fix FFmpeg encoding of reported framerate for some format (e.g. AVI)
- fix incorrect use of .mov container when writing .mp4 files
- fix FFmpeg audio decoding as noise when when unknown sample format is encountered
- improve FFmpeg encoding file-format selection, adding new MOV, MP4 modes and deprecating old QT/MOV/MP4 auto-select mode
- improve FFmpeg loading, allow loading from more system paths (and REAPER UserPlugin path)
- improve accuracy of timestamps for Windows Media encoder with ND framerates
- add support for decoding AV1 via VLC
- allow encoding to arbitrary fractional framerates
- support entry of commas as decimal point in framerates when rendering
- support files with MXF extension, if supported by installed FFmpeg/VLC
- when changing video decoder priority list, prompt to re-open all media in order to use new decoders 

Ruler lanes:
- do not draw double divider line when there is insufficient room to display all lanes
- ensure that with default preference settings, ruler cannot be resized small enough to hide default ruler lanes
- fix intermittent display issue on undo/redo
- improve behavior when moving multiple regions/markers across hidden ruler lanes
- prevent creating regions or markers in locked ruler lanes
- prevent moving regions and markers to locked lanes 

Ruler:
- don't show region/marker editing guidelines until mouse moves
- fix skipped grid line display with certain tempo/time signature marker scenarios
- reword some items in time selection right-click menu
- when editing regions with contents, show editing guidelines at unedited position, because all project contents will move 

Console 1:
- deactivate tracks that are hidden in both TCP/MCP
- improve automatic device name detection to include future Softube devices
- support plugin/Console 1 requests from controller 

Region manager:
- add undo point after importing regions/markers from csv file
- support importing regions/markers from csv file by dragging into region manager window, hold shift key to merge 

Regions/markers:
- support assigning actions to region/marker click mouse modifier
- support importing regions/markers from REAPER project file (.RPP) 

Video processors:
- fix knob sizing with DPI changes/multimonitor
- display video processor CPU use as %v in FX chain, project bay, performance monitor 

Actions:
- actions to select item under mouse respect 'selecting item selects group' setting 

CLAP:
- fix transport flags when REAPER is recording 

Envelope panels:
- fix slight offset in readout of current value 

Free item positioning:
- preserve media item height when moving to a new track (7.60 regression) 

IDEs:
- syntax highlight built-in pow() function when editing JSFX/Video Processors/EEL2 ReaScripts 

Markers:
- when markers overlap, mouse targets the later (visible) marker 

Media item properties:
- fix behavior when enabling section source and project start time offset exists 

Mouse modifiers:
- fix descriptions of modifiers to set time selection or loop points to region 

Render:
- improve ordering of file-format modes, grouped alphabetically within logical groups (uncompressed, compressed, raw, CD, video) 

Take markers:
- always add marker when running quick-add actions, even if there is already a marker at that location 

Tempo/time signature:
- respect 'allow partial measure' setting when editing earlier tempo envelope points 

Time signature markers:
- when 'allow partial measure before this marker' enabled, display beat position in tempo marker editor based on previous time signature marker 

UI:
- improve responsiveness of UI when under very heavy audio-thread CPU load in playback/rendering
