Igor,
I haven't closed out 3674, because I haven't covered that part yet. Chef docs are now in the wiki, but I'll be adding ceph-disk docs shortly.

There are a few things to keep in mind when upgrading from Bobtail,
specifically with the monitor daemons. Please see the upgrade guide
and/or the complete release notes. In short: upgrade all of your monitors
(more or less) at once.
Cuttlefish is the first Ceph release on our new three-month stable release
cycle. We are very pleased to have pulled everything together on schedule
(well, only a week later than planned). The next stable release, which
will be code-named Dumpling, is slated for three months from now
(beginning of August).
You can download v0.61 Cuttlefish from the usual locations:
* Git at git://github.com/ceph/ceph.git
* Tarball at http://ceph.com/download/ceph-0.61.tar.gz
* For Debian/Ubuntu packages, see http://ceph.com/docs/master/install/debian
* For RPMs, see http://ceph.com/docs/master/install/rpm
