 Version 7.38.0

 Framework
   - Added dynamic hash table for `mlt_properties` for better performance.
   - Fixed memory corruption in `mlt_pool`.
   - Added warning on file open failure when parsing in `mlt_properties`.

 Modules
   - Added `hwaccel_scale` filter with preview scaling (scale_vaapi,
 scale_vulkan
 , scale_d3d11, scale_vt (macOS)).
     This adds an environment variable `MLT_AVFORMAT_HWACCEL_PPS` to
 provide a
     limiter to hwaccel because transfering uncompressed video between
 memory
     CPU and GPU memory is heavy.
     PPS = maximum pixels per second. Anything over it skips hwaccel.
   - Added *basic* support for **OpenFX** *filter* plugins.
     OpenFX has many features. This is a summary of what is NOT yet
 included:
     - GPU rendering
     - exotic parameter types: Integer2D, Integer3D, Double3D, Custom,
 Bytes, Pag
 e, PushButton
     - plugin-driven keyframe animation; but MLT-driven does work
     - tile-, slice-, or frame-based multi-threading (only plugin internal
 thread
 ing)
     - multi-resolution
     - temporal clip access
     - overlays & dialogs
     - timeline queries (e.g. `getTime()`)
     - generator, transition, retimer
     - parametric curves
   - Added `lut` parameter to `avformat` producer.
   - Added `attached_pic` property to `avformat` consumer.
   - Added `movit.overlay_blend` video filter.
   - Added `compositing` property to `movit.overlay` transition.
   - Added constant-power crossfade to `mix` audio transition.
   - Added rounded corner support for `rect` in `kdenlivetitle`.
   - Added typewriter properties to `subtitle` filter.
   - Added underline and strikethrough to the `text` and `qtext` filters.
   - Changed `qtext` `style` property to support family named styles.
   - Added anchor point support for arbitrary rotations in `qtblend`.
   - Allow relative paths for images in `kdenlivetitle`.
   - Updated Glaxnimate module to version 0.6.0.
   - Switched to `QImage` scaling when downscaling in `qtblend`.
   - Deprecated `obscure` and `watermark` filters.
   - Install the jackrack module's blacklist files.
   - Fixed subtitle stream type metadata.
   - Fixed mutex initialization in `avformat` no-validate mode.
   - Fixed crash when using `linearblend` deinterlacer.
   - Fixed black bar with HEVC hwaccel decode and scale on Windows.
   - Fixed crash with hardware scaler and interlaced video.
   - Fixed converting 8-bit full to limited range with hwaccel.
   - Fixed alpha in 12-bit ProRes with alpha.
   - Fixed `movit` linear color not matching CPU filters.
   - Fixed `multi` consumer making extra linear color conversions.
   - Fixed regression writing raw FLAC.
   - Fixed `qtblend` filter returning unexpectedly large frames.
   - Fixed `qtext` outline encroaching on fill color.
   - Fixed wrong last+ frame when `eof=loop` in Glaxnimate.
   - Fixed `brightness` filter on track below a clip with transparency.

 Other
   - Fixed crash during exit cleanup in `melt`.
   - Continued build improvements for MSVC.
   - A lot of metadata fixes and improvements.
   - Many fixes to API documentation.
   - Added C++ and Python to the API docs.
   - Added two 10-bit VP9 encoding presets.
