Improvement

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).
