Not that I know of.

Yes, please.  Please do a rough check of history, in case they used to
have a serial number at one time.  Pick one that is higher than that.
If master and branch-1.11 have different versions of files, master
should have its serial bumped by a few, let's say five at least, so we
don't run into trouble when we update 1.11.  Patches against active
branches preapproved.

Thanks,
