Happy Houdini 21 release day! H21 is compatible with both MOPs and MOPs Plus (for Python 3.11) so you shouldn't have to worry about any upgrades. Have fun!

Clarification: Houdini 21 by default uses Qt6 and doesn't have PySide2 compatibility. This will break some tools that use a custom UI. You can get around this by installing a Qt5 build of H21. I'll add Qt6 support soon!
