Versions are numbered as YYYY.MM.P.B, where:
YYYY - YEAR of release
MM - MONTH on which it was released (usually end of); beta versions are numbered as MONTH * 100
P - number of PATCH/fix (0 if it was first release)
B - total number of internal builds since May 2022 (last reset of build number was short before 2022.5 release, not every build is released to public)
So, for example: 2022.6.1.53 means: update #1 for version released at end of June(6) 2022, 53rd build in total (since May 2022).
There are no releases in July and December because of Holiday season peak.
