My apologies for taking so long... The CVE
took longer than expected and there was
some issues with recent patches,
which caused another release..

Turning off a protocol version (v4.0)
on the server by default which this rc
release does, is not a small thing
although with the 7.X kernels the
v4.0 client is already off.

So the next rc releases will contain
the current outstanding patches (a rc
release for each patch set) then creating
another release (2.9.1)...

Definitely in time for the upcoming Bakeathon!
