Hello. We've just installed server git hooks that verify git messages for a correct ChangeLog format. For a limited time period, please still apply ChangeLog changes to the corresponding ChangeLog files. We'll use it for comparison of auto-generated CangeLog entries.
The format is documented here: https://gcc.gnu.org/codingconventions.html#ChangeLogs And I would recommend to install the new 'git gcc-verify' hook from: contrib/gcc-git-customization.sh Feel free to contact me about future troubles you'll see. Thanks, Martin
