Hi,

This is the first release since we have split the drbd-utils
code off into a dedicated repository.

  The advantage is that we have one drbd-utils package that
  works with different versions of the drbd-module (drbd driver).

  I am referring here to different minor versions like 8.4.4 and
  8.4.5 as well as to different major versions like 8.3.x, 8.4.x
  and 9.0.x. All those different versions of the drbd kernel
  code can be controlled with the tools from one drbd-utils package.

  The drbd-utils package comes with man pages for the three major
  versions including symlinks that default to version 8.4.
  I.e "man drbd.conf" will bring the 8.4 version to you screen.
  "man drbd.conf 9.0" will show you the possible options for 
  drbd 9.0.

The drbd-8.4.5 kernel driver has the usual number of fixes
to bugs that affect a rather small portion of our user base.

In the drbd-utils package there is a bug-fix that needs to
be high-lightened. With the 8.4.3 release a regression was
introduced that causes data loss when doing "offline reisze"
with internal meta-data!! This regression is fixed with this
release.

drbd-utils-8.9.0
--------
  * Initial release of unified drbd-utils
  * Supports drbd drivers 8.3, 8.4 and 9.0
  * Ships with man page links defaulting to 8.4
  * Fixed offline resizing in drbdmeta; A regression that causes
    data loss, since meta-data was written with wrong offset.
    The regression was introduced with 8.4.3
