Shall we wait till the final 9.3.0 release (Sep 8) - https://discourse.vtk.org/t/vtk-9-3-0-release-cycle/11598/5?

Good question, I thought it'd be best to update ASAP to get rid of the vulnerability and not wait until the final release comes out with its potential long delays (considering rc2 should've come out August 11 and was set for June 22 before that, and still hasn't been released, seems like there may be quite a delay). It doesn't look like this release candidate is breaking any tests here.

I think that if the vulnerabilities aren't causing any significant issues/concerns right now on our side, we may as well wait if you prefer.

Thanks for the details. Yeah, the updated timetable also seems to be getting delayed. So, let's merge this now. We would also need to do a release.
