Note
This particular PR must be true-merged to main.

• This PR is only ready to review when it is marked as "Ready for Review". It represents the merge to the main branch of an upcoming release (version number in the title).
• It will act as a staging branch until we are ready to finalize the release.
• We may cut any number of alpha and release candidate (RC) versions off this branch prior to formalizing it.
• This PR is primarily a merge commit, so reviewing every individual commit shown below is not necessary since those have been reviewed in their own PR. However, things important to review on this PR once it's marked "Ready for Review":
  • Does this PR target the right branch? (usually, main)
  • Are the appropriate version bumps and release note edits in the end of the commit list (or within the last few commits). In other words, "Did the 'release prep' PR actually land on this branch?"
  • If those things look good, this PR is good to merge!
