Thanks for raising the thread.  I'm in a similar boat.  Though, prior to
an update, we'd review the changes via the mailing lists.

The main list we used was:
https://lists.freebsd.org/pipermail/svn-src-stable-12/
but that appears dead.  Normally we'd update fortnightly or trigger an
update when there was an incremental patch update to "release" as
advised via:
https://lists.freebsd.org/pipermail/svn-src-release/
suspect also dead.

Suggestion  - final entry in dead lists to provide a pointer to its git
equivalent?

I suspect that
https://lists.freebsd.org/pipermail/dev-commits-src-branches/2021-January/thread.html
is the stable-12 equivalent but are incremental patch releases also
available here?

As a change management task, I would hope that a mapping between svnlite
and git would've become available for FreeBSD users, similar to the cvs
to svnlite migration.  I guess we need to create a test machine to
figure out the commands we need for git to replace what we use in the
scripts (mainly "update -r "{$DATE}", diff and log along with the
incantation to create a git repository).

I wish that I could articulate the reason to management that FreeBSD is
making the move from svn to git?

Is there a timeline when svn for stable-12 /usr/src disappears?

(I'm dreading a ports move to a git paradigm...)
