• Fixed a possible crash when connecting to an RTMP server [notr1ch]
• Fixed a possible RTMP disconnect/timeout on Windows systems without IPv6 connectivity when connecting to a dual-stack RTMP server [notr1ch]
• Fixed browser source custom CSS injection for sites with 'require-trusted-types-for' CSP (e.g., YouTube) [vvto33]
• Adjusted IPv4/IPv6 address selection to be stricter [notr1ch]

Previous release notes

• Fixed a possible crash when loading scene data [norihiro/notr1ch]
• Fixed an issue with CoreAudio AAC timestamps causing a stream to fail [derrod]

• Fixed source tree icon spacing [Warchamp7]
• Adjusted sizing of Classic audio meter elements [Warchamp7]

New Features

• Added support for Multitrack Video streaming [palana]
  • On Twitch, this is known as Enhanced Broadcasting. For more information, see: https://help.twitch.tv/s/article/multiple-encodes
  • The supported audio channel configurations are stereo or mono.
  • This feature is currently only available on Windows and requires an NVIDIA GTX 900, GTX 10, or RTX 20 series GPU or newer or an AMD RX 6000 series GPU or newer. Support for other operating systems and GPU vendors is planned.
  • When this feature is enabled, the following data about your system will be sent to the streaming service when starting a stream:
    • OBS version and audio/video settings (Resolution, framerate, audio channels/tracks)
    • CPU info (Name, speed, core counts)
    • GPU info (Model, memory, driver version, device ID, vendor ID)
    • Memory info (Free, total)
    • OS info (name, version, arch, emulation)
  • Windows info (Gaming feature status: Game Bar, Game DVR, Game Mode, Hardware-accelerated GPU Scheduling)
  • Multitrack Video settings (Maximum streaming bandwidth, maximum video tracks)
• Added support for Enhanced RTMP/FLV multi-track audio and video [palana/kc5nra]
  • Replaces the old metadata-based "VOD Track"
