Dear DRBD users,

this is drbd-reactor version 1.11.0. There has been a minor new feature
that allows disabling adjusting of DRBD resources on startup[4].

The promoter now supports an on-disk-detach policy[1]. When the local
DRBD disk on a Primary gets detached, the new "fail-over" policy stops
services if an UpToDate peer is available, triggering a failover. The
default ("ignore") preserves existing behavior.

We fixed initial startup ordering on intentionally diskless nodes[2].
Diskless nodes tend to be ready faster and could win the startup race
even when they shouldn't. We now also consider disk state during initial
startup.

drbd-reactorctl status learned a --json flag[3] for machine-readable
output.

Please test, if we don't find any bugs we will release the final version
in about a week from now.

Regards, rck
