In common with many other projects (and following the changed default branch name at github) we have renamed the master branch in the latex3 and latex2e repositories to "main". If you have a local clone of the latex3 or latex2e repositories please execute git branch -m master main git fetch origin git branch -u origin/main main git remote set-head origin main in each repository to rename your local branch to main and to re-establish the tracking of the project repository main branch. Announcing here for these two core repositories but the master branches in related repositories such as hyperref, iftex have been renamed already and the remaining ones will be done in due course.
