[llvm-dev] Renaming The Default Branch

Hi,
Currently there are two issues I would like to address:

1) While we understand new commits to the 'main' branch are somewhat
slow
to synchronize (about 5 minutes) to the old 'master' branch, we are not
planning to address the issue at this time.  Developers will notice an
immediate improvement by migrating their workflows to the new 'main'
branch.  We advise everyone to stop relying on 'master' and migrate to
the
'main' branch as soon as possible.

2) As Hans just pointed out, the automation we have in place to make
commits post to the mailing lists is not working correctly.  I will be
looking into this today and hope to have it resolved soon.

-Mike
