v0.94.6 Hammer released

This Hammer point release fixes a range of bugs, most notably a fix for unbounded growth of the monitor’s leveldb store, and a workaround in the OSD to keep most xattrs small enough to be stored inline in XFS inodes.

We recommend that all hammer v0.94.x users upgrade.

For more detailed information, see the complete changelog.
