Hello operators,

You may have heard about a potential data-loss bug [0] that was recently 
discovered.  It has been fixed in the upcoming wallaby release and we 
are planning to backport to all stable branches and do new os-brick 
releases from the releasable stable branches.

In the meantime, the bug occurs if the multipath configuration option on 
a compute is changed while volumes are attached to instances on that 
compute.  The possible data loss may occur when the volumes are detached 
(migration, volume-detach, etc.).  Thus, before the new os-brick 
releases are available, the issue can nonetheless be averted by not 
making such a configuration change under those circumstances.

The new os-brick releases will be:
- victoria: 4.0.3
- ussuri: 3.0.6
- train: 2.10.6

The stein, rocky, and queens branches are in Extended Maintenance mode 
and are no longer released from, but critical fixes are backported to 
them when possible, though it may take a while before these are merged.
