This is a patch release that addresses issues found in version 2.1.
A few more regressions related to 3D model rendering are fixed in this release. Also, on macOS the applications are now notarized and the bundle metadata has been fixed to contain appropriate IDs.
This also acts as a test for the revised build scripts that now live in a repository separate from the main Doomsday source code. The separation makes it easier to maintain the scripts while building releases from different branches.
