[Bug 1492227] Re: 0.94.3 stable update

[oh]

Ceph 0.94.4 is out with important bug fixes, released oct 19.  Will it
appear in vivid/wily soon?

v0.94.4 Hammer released

This Hammer point fixes several important bugs in Hammer, as well as
fixing interoperability issues that are required before an upgrade to
Infernalis. That is, all users of earlier version of Hammer or any
version of Firefly will first need to upgrade to hammer v0.94.4 or later
before upgrading to Infernalis (or future releases).

All v0.94.x Hammer users are strongly encouraged to upgrade.

  V0.94.3 HAMMER

  This Hammer point release fixes a critical (though rare) data
  corruption bug that could be triggered when logs are rotated via
  SIGHUP. It also fixes a range of other important bugs in the OSD,
  monitor, RGW, RGW, and CephFS.

  All v0.94.x Hammer users are strongly encouraged to upgrade.
