This is the release containing all the features that formed DRBD+ before:
 * bit map in unmaped pages -> device sizes > 4TB (up to 16TB currently)
 * DRBD stacking -> replication to a 3rd node (even 4 are supported)
 * checksum based resync -> Speeds up resync processes over slow networks.

Besides these highlight, again a number of bugs was fixed, see the first five
items on the change log. Users of drbd-8.2.7 should upgrade to 8.3.0 .

BTW, this is the successor of drbd-8.2.7 and the drbd-8.2.x branch.
