Sync master to alpha - #3303

[PKulkoRaccoonGang]

[inform]:

we don’t want to release off master anymore; instead, we only want to release off specific named release branches (release-23.x)

According to the discussions on PWG we decided to have several branches, so this PR for inclusion in master has lost its relevance.
The alpha branch will be used for further preparation for the release.
#3303
