[Release-testers] 12.0.0 Release Update

[Tom Stellard via Release-testers]

Hi,

There is just over a week left until 12.0.0-rc2 is tagged.  After -rc2 is
tagged, we will only be merging critical fixes into the branch.  Any other
fixes will need to wait until the 12.0.1 release.

Here is a list of outstanding bugs that we are tracking for the release:
