+Version 2.13.0 beta1
+--------------------
+
+*(Released Wed, 14 Jan 2015)*
+
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Ganeti now internally retries the instance creation opcode if
opportunistic
+ locking did not acquire nodes with enough free resources. The internal
retry
+ will not use opportunistic locking. In particular, instance creation,
even
+ if opportunistic locking is set, will never fail with ECODE_TEMP_NORES.
+- The handling of SSH security had undergone a significant change. From
+ this version on, each node has an individual SSH key pair instead of
+ sharing one with all nodes of the cluster. From now on, we also
+ restrict SSH access to master candidates. This means that only master
+ candidates can ssh into other cluster nodes and all
+ non-master-candidates cannot. Refer to the UPGRADE notes
+ for further instructions on the creation and distribution of the keys.
+- Ganeti now checks hypervisor version compatibility before trying an
instance
+ migration. It errors out if the versions are not compatible. Add the
option
+ --ignore-hvversions to restore the old behavior of only warning.
+- Node tags starting with htools:migration: or htools:allowmigration: now
have
+ a special meaning to htools(1). See hbal(1) for details.
+- The LXC hypervisor code has been repaired and improved. Instances
cannot be
+ migrated and cannot have more than one disk, but should otherwise work
as with
+ other hypervisors. OS script changes should not be necessary. LXC
version
+ 1.0.0 or higher required.
+
+New features
+~~~~~~~~~~~~
+
+- A new job filter rules system allows to define iptables-like rules for
the
+ job scheduler, making it easier to (soft-)drain the job queue, perform
+ maintenance, and rate-limit selected job types. See gnt-filter(8) for
+ details.
+- Ganeti jobs can now be ad-hoc rate limited via the reason trail.
+ For a set of jobs queued with "--reason=rate-limit:n:label", the job
+ scheduler ensures that not more than n will be scheduled to run at the
same
+ time. See ganeti(7), section "Options", for details.
+- The monitoring daemon has now variable sleep times for the data
+ collectors. This currently means that the granularity of cpu-avg-load
+ can be configured.
+- The 'gnt-cluster verify' command now has the option
+ '--verify-ssh-clutter', which verifies whether Ganeti (accidentally)
+ cluttered up the 'authorized_keys' file.
+
+New dependencies
+~~~~~~~~~~~~~~~~
+
+- The monitoring daemon uses the PSQueue library. Be sure to install it
+ if you use Mond.
+- The formerly optional regex-pcre is now an unconditional dependency
because
+ the new job filter rules have regular expressions as a core feature.
+
+Known issues
+~~~~~~~~~~~~
+
+The following issues are known to be present in the beta and will be fixed
+before rc1:
+
- - Issue 1018: Cluster init (and possibly other jobs) occasionally fail to
start.

+ Version 2.12.2
+ --------------
+
+ *(Released Wed, 25 Mar 2015)*
+
+ - Support for the lens Haskell library up to version 4.7 (issue #1028)
+ - SSH keys are now distributed only to master and master candidates
+ (issue #377)
+ - Improved performance for operations that frequently read the
+ cluster configuration
+ - Improved robustness of spawning job processes that occasionally caused
+ newly-started jobs to timeout
+ - Fixed race condition during cluster verify which occasionally caused
+ it to fail
+
+ Inherited from the 2.11 branch:
+
+ - Fix failing automatic glusterfs mounts (issue #984)
+ - Fix watcher failing to read its status file after an upgrade
+ (issue #1022)
+ - Improve Xen instance state handling, in particular of somewhat exotic
+ transitional states
+
+ Inherited from the 2.10 branch:
+
+ - Fix failing to change a diskless drbd instance to plain
+ (issue #1036)
+ - Fixed issues with auto-upgrades from pre-2.6
+ (hv_state_static and disk_state_static)
+ - Fix memory leak in the monitoring daemon
+
+ Inherited from the 2.9 branch:
+
+ - Fix file descriptor leak in Confd client
+
+ Known issues
+ ~~~~~~~~~~~~
+
+ - GHC 7.8 introduced some incompatible changes, so currently Ganeti
+ 2.12. doesn't compile on GHC 7.8
+ - Under certain conditions instance doesn't get unpaused after live
+ migration (issue #1050)
+ - GlusterFS support breaks at upgrade to 2.12 - switches back to
+ shared-file (issue #1030)
