Improvement

• Backported in #42841: Update tzdata to 2022f. Mexico will no longer observe DST except near the US border: https://www.timeanddate.com/news/time/mexico-abolishes-dst-2022.html. Chihuahua moves to year-round UTC-6 on 2022-10-30. Fiji no longer observes DST. See https://github.com/google/cctz/pull/235 and https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1995209. #42796 (Alexey Milovidov).

Build/Testing/Packaging Improvement

• Backported in #42965: Before the fix, the user-defined config was preserved by RPM in $file.rpmsave. The PR fixes it and won't replace the user's files from packages. #42936 (Mikhail f. Shiryaev).
• Backported in #43041: Add a CI step to mark commits as ready for release; soft-forbid launching a release script from branches but master. #43017 (Mikhail f. Shiryaev).
