Introduced for yesterday's betas (macOS 12.3, etc). A more finely-grained API, tuned for the needs of screen capture – letting you specify which apps and windows appear, the format of the capture, frames being able to be elided if nothing has changed, and so on.

And interestingly accompanied with a pull request to OBS to integrate it right away (under the banner of "Developer Ecosystem Engineering"), with changes that seem to follow the current work and adhere to its development process, ie not just a code dump or kthxbai.patch file against a months-old revision.
