VTK 9.3.0.rc2 has been tagged! Downloads for docs, sources, wheels should be available on the VTK site no later than tomorrow (October 31). Hopefully this is the last release candidate before the full 9.3 release. Please report any issues you find.

Release notes: https://gitlab.kitware.com/vtk/vtk/-/blob/master/Documentation/release/9.3.md

If there are important items missing from the release notes, please make MRs updating them which target master and are assigned to the 9.3 gitlab milestone (so they can be backported to release).
