in drbd-utils a number of fixes got queued up, so it is time
to start a new release cycle of it.
Last not least is has a number of important fixes in the
drbd-9 user-space parts.

On the kernel driver side, it is more than 6 month ago, since
the last pre release. A lot was done in the meantime. The most
time consuming part was probably the complete merge of the
drbd-8.4 branch into the drbd-9 branch.
A lot of progress was made on the stability of the driver.
Kernel crashes are no longer an issue we are confronted in
out day to day work on the code. As long as you do not dig
into our test suite drbd-9 behaves mostly reasonable these 

Please let us know if you find issues.

This are a release candidates. Do not use in production.
