Dear DRBD users,

this is drbd-reactor 1.10.0. This version is a bit bigger than the last
ones, but contains some nice features and fixes. It also saw some very
minor changes since RC1, see changelog below. The noteworthy overall
changes:

We now support two node clusters if fencing is properly configured[1].
The split-brain avoidance policy is auto detected and there are no
visible changes for existing (i.e., quorum) users. There are edge cases
where we want to support two node clusters with fencing, but all users
that can should use DRBD quorum as avoidance mechanism instead.

The second change worth mentioning is that we now generate a stronger
dependency (i.e. BindsTo) for the drbd-promote at .service. Details can be
found here[2].

Starting with this release I will also GPG sign the release commit and
the git tag with the same key this mail and the PPA are signed.

Regards, rck
