OBS Studio is the free and open source recording and livestreaming app used by many content creators and a big new release is now available with YouTube integration.
This means you can now connect up with YouTube instead of supplying a streaming key, and it gives you a bunch of options to help manage YouTube livestreams. Much like the Twitch integration, for Linux you need to be using their official package otherwise you need to supply your own client keys for API interaction (source).
Other new features include an 18-scene multiview option, a feature to allow browser sources limited control over OBS if allowed and an option to draw safe areas in the the preview.
Plenty of tweaks were also made to the software like an optimized media source to reduce CPU usage, hidden sources will have their text dimmed in the source list, there's a new Missing Files Check menu item in the Scene Collections menu, gif files will be animated in the preview window in Studio Mode, drag and drop for scenes & sources was also re-enabled for Linux and Linux also now has CTRL+R to reload browser panels.
Apart from that there's numerous bug fixes like a bug on Linux with Wayland where the cursor capture was out of position.
