There's some big new features included in this release including HDR for HEVC over RTMP, AV1 support for VA-API, AV1 support for WebRTC/WHIP output, Video Capture Device (PipeWire) source type, multi-track audio support for mpegts, GPU rescaling options for streaming and recording outputs, a rework of the Image Slideshow source and more.

And then there's a good few bug fixes included in this release too like being unable to use QSV in the Flatpak package.
