[DRBD-announce] drbd-8.0.0.tar.gz

[Philipp Reisner <philipp.reisner@linbit.com>]

Hi There,

We have something to celebrate here...

   DRBD - 8.0.0
   ============

This is the official entry to the changelog:

8.0.0 (api:86/proto:86)
--------
 * No effecitve changes to rc2.


But I want to remind you about the changes relative to the 0.7
release of DRBD:
----------------
 * Removed support for Linux-2.4.x
 * Cleanup of the wire protocol.
 * Added optional peer authentication with a shared secret.
 * Consolidated state changes into a central function.
 * Improved, tunable after-split-brain recovery strategies.
 * Always verify all IDs used in the protocol that are used as pointers.
 * Introduced the "outdate" disk state, and commands for managing it.
 * Introduced the "drbdmeta" command, and require the user to create
   meta-data explicitly.
 * Support for primary/primary (for OCFS2, GFS...)
 * Replaced the sync-groups with the sync-after mechanism.
 * The "common" section in the configuration file.
 * Replaced the generation counters (GCs) with data-generation-UUIDs
 * Improved performance by using Linux-2.6's BIOs with up to 32k per
   IO request. Before we transferred only up to 4k per IO request.
 * A Warning if the disk sizes are more than 10% different.
 * A connection teardown packet to differentiate between a crash
   of the peer and a peer that is shut down gracefully.
 * External imposable SyncPause states, to serialize DRBD's resynchronisation
   with the resynchronisation of backing storage's RAID configurations.
 * Backing storage can be hot added to disk less nodes.
 * Prepared for advanced integration to Heartbeat-2.0
 * Changed internal APIs so that missed writes of the meta-data super
   block are reported as they happen.
 * The http://usage.drbd.org sub project.
 * Rewrote the scanner/parser of drbd.conf. 10 times smaller/faster and
   easier to maintain.
 * Asynchronous meta-data IO [ Code drop from the DRBD+ branch ]

To have our release policy more transparent in the future:

Bugfix releases will increase the 3rd number, e.g. 8.0.1, 8.0.2 etc...

Releases that introduce small new features will increase the second
number, resetting the third number: 8.1.0 etc...

In the next weeks we will try to update the http://www.drbd.org
with a bit of new content.

Oh, yes, and then we will prepare it for inclusion into 
Linus' mainline Linux.
