This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "OpenBTS' transceiver retro-fit".

This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (184e7680aab56afc561c891273ff5454a50843d8)
             N -- N -- N (34c4eff3c57ea994d030cdaef019c426a3222c3b)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.
