Let me point out a few highlights:

*) Use drbd-overview instead of 'cat /proc/drbd'

*) The udev rule provides you nice symlinks for the drbd device nodes:


*) include statement:
   Although we have not yet changed the configuration examples, but now
   it is possible to have a drbd.conf that looks like this:

   include "/etc/drbd.d/global_shared.conf"
   include "/etc/drbd.d/*.res"

*) the congested_fn should improve overall system performance on machines
   with hight IO load.

*) The outdate-wfc-timeout allows one to tune the wait-for-connect 
   time down to 1 second in case the peer is already outdated.

The changelog:

8.3.1 (api:86/proto:86-89)
 * Fixed drbdadm invalidate on disconnected devices (reg in 8.2.7)
 * Fixed a hard to trigger spinlock deadlock when using device stacking
   with the upper device having a smaller minor number than the lower device.
   (Bugz 210)
 * Adding a missing range check in ensure_mdev()
 * Implemented a congested_fn; the kernel can keep its pdflushes running now
 * Improvements the connection code for high latency links
 * Fix for several potential memory leaks when allocating a device
 * Use an additional meta data bit to store the fact of an old crashed primary
 * Udev rule that populates /dev/drbd/by-res/ and /dev/drbd/by-disk/
 * New timeout option: outdated-wfc-timeout
 * New drbdmeta option: --ignore-sanity-checks
 * Include statement for drbd.conf
 * Improvements to drbd-overview.pl
 * Fixed snapshot-resync-target-lvm.sh to work with more than 10 devices
 * Do not force a full resync after a detach on a primary node
 * Compatibility with Linux 2.6.27, 2.6.28 and 2.6.29


And, since the init script of 8.0.15 is broken on some distributions, here
is 8.0.15 with a micro patch, now 8.0.16.

8.0.16 (api:86/proto:86)
 * Fixed the init script to work with all flavors of LSB
