- master — default target for all changes (new features + bug fixes).  
  If the change should also go to maven-4.0.x, request a backport in the PR.

- maven-3.10.x — target for 3.x changes (new features + bug fixes).  
  If the change should also go to maven-3.9.x, request a backport in the PR.
  maven-3.9.x should receive only serious bug fixes, as it is approaching EOL.

Backports are typically handled by maintainers;
