OBS Studio 27.0 is a major update because it’s the first version to introduce support for the Wayland display server on Linux systems.
This means that you can finally use OBS Studio on Wayland, and the support comes with a new PipeWire capture source. The devs warn that Ubuntu users would need to use Ubuntu 20.10 (Groovy Gorilla) or higher for PipeWire capture. Also for Linux users, the new OBS Studio release adds service integration and browser dock support. In addition, it improves support for VST (Virtual Studio Technology) paths and fixes a crash that could occur when audio backends have been disabled.
