Add changes from 2021.3.3 (#13388)
Initially changes for 2021.3.1 were delivered to beta, subsequently it was decided to avoid complications with translations, to make changes directly on RC.
The changes were cherry picked from beta.
There were then several more changes made squashed / merged to RC
These changes need to be cherry picked back into the beta branch.
This was done in #13185
Changes for 2021.3.3 were cherrypicked directly to rc.
But because rc and beta/master have diverged, these changes need to be cherrypicked back to master and beta.
An exchange of merging master and beta has already occurred since the last release.
As a result, these changes need to be cherry-picked directly to master, to get eventually merged to beta.
Description of how this pull request fixes the issue:
Update the changes file from release-2021.3.3
No other introduced changes from 2021.3.2 and 2021.3.3 need to be cherry-picked back to master.
This is because 2021.3.2 and 2021.3.3 was created from code existing on master.
