I forget to announce that release, but better late than never.
Again, this should continue to be a boring release, which is good.

The main fixes are that stacked handlers got fixed and that adjust now
also verifies IPs.

The main feature is that if you use DRBD9 and already like the
"drbdsetup status" output that prints intentionally diskless clients in
green (instead of red for volumes that actually lost a disk), got a new
feature: So far when you converted a volume with a disk, to one that is
intentionally diskless (i.e., you/drbdmanage/linstor) converted it and
set "disk none", this was not communicated to the kernel on "adjust",
and these now intentional diskless volumes were still printed in red.
This was not only a matter of red vs. green, this also included
"drbdsetup events2", "drbsetup status --json", drbdmon, and drbdtop.
While easy to fix for an admin (down/up), this confused users. Users
don't like red ;-). This was now added, but also requires the
corresponding change in the DRBD9 kernel module which will land in DRBD9
release 9.0.15. After that a DRBD powered traffic light should be easy
to implement...

 * drbdmon: allow to start in problems view (--problems)
 * drbdadm,v9: fix always failing stacked handlers from kernel
 * drbdadm,v9: adjust now hands over the information that a
 * diskfull->diskless change was intentional. Now shown as "green
 * drbdadm,v9: adjust verifies now IPs
