○ Currently only supported by/enabled for YouTube as a beta feature
○ HDR is not yet implemented

● Added a DLL blocking feature for Windows. This allows OBS to block problematic DLLs from attaching to OBS and causing freezing or crashes, for example 3rd party overlay hooks and outdated video capture devices. [notr1ch]
○ This blocks old versions of popular VTubing software virtual cameras that are known to cause freezes when accessing video capture device properties. If you are affected, please update to the latest version of your VTubing software.

● Added an option to preload media sources used in Stingers to memory, to avoid frame skips during transitions [Jim]

● Added compatibility notices in the Window and Game Capture sources for Windows [derrod]
● Added the ability to zoom browser docks with Ctrl - and + and the right click menu [WizardCM]

○ These offer greater compatibility than MKV while providing similar resilience against data loss due to crashes, running out of space, etc.
