As of today, there will be not more 8.2 releases.

DRBD 8.3 is compatible, it will accept from 8.2:
- configuration (*1)
- wire protocoll
- meta data on disk

... and upgrade from 8.2 to 8.3 is completely seamless, and can 
be done in as "rolling upgrade".

I think is should be the natural upgrade path.

  The "outdate-peer "handler got renamed to "fence-peer", but the
  parser accepts both. Automatic update of the config file could
  by done by "drbdadm dump all > /etc/drbd.conf_new"

The reason that it is called "drbd-8.3" instead of "drbd-8.2"
because a number of new features got included (stacking),
but there where not fundamental internal changes.
