Testing is complete which means its time for another Pacemaker bugfix-
only release.
Packages for Pacemaker and it's immediate dependancies can be
downloaded from the usual location:
http://software.opensuse.org/download/server:/ha-clustering
The source can be obtained from:
http://hg.clusterlabs.org/pacemaker/stable-0.6/archive/Pacemaker-0.6.4.tar.bz2
For a breakdown of the available packages and what parts are optional,
please refer to

The next 0.6 release (if needed) will be mid-June.
In other news, I hope to have the 0.7 (unstable) series ready for
people to try in the next couple of weeks.
I'm really excited about some of the features we've been adding. Some
notable changes for 0.7 include:
+ Overhaul of the configuration syntax
+ Better validation of configurations with RelaxNG schemas
+ Admin tools now set options consistently
+ A new tool for testing your cluster before it goes into production
+ A new tool for making, testing and verifying changes _before_
uploading them to the cluster
+ Ability to automatically upgrade to the latest configuration syntax
+ Adopt libxml2 as the XML processing library (this should be
faster and reduce the amount or copying that was occurring)
+ Implement XPath based versions of query/delete/replace/modify
Eg. Find _all_ options telling resources to stop: cibadmin --
query --xpath '//[EMAIL PROTECTED]"target-role" and value="Stopped"]'
+ Bug LF:1459 - Allow failures to expire
+ Replace the failure-stickiness mess with a simple 'migration-
threshold'
+ Bug LF:1438 - Allow the list of all/active resource operations to
be queried by crm_resource
+ Bug LF:1883 - crm_mon should display fail-count and operation
history
+ Bug LF:1884, Bug LF:1885 - Implement N:M ordering and colocation
constraints
+ Implement a client-side operation timeout for CIB connections
+ Implementing the ability for clients to connect to remote
instances of the CIB
+ Implement a stack-independant version of pingd - no need to add
ping nodes to ha.cf

Andrew

+ High: crmd: Bug LF:1881 LF:1882 - Overhaul the logic for
operation cancelation and deletion
+ High: crmd: Bug LF:1894 - Make sure cancelled recurring
operations are cleaned out from the CIB
+ High: PE: Bug N:387749 - Colocation with clones causes
unnecessary clone instance shuffling
+ High: PE: Ensure 'master' monitor actions are cancelled _before_
we demote the resource
+ High: PE: Fix assert failure leading to core dump - make sure
variable is properly initialized
+ High: PE: Make sure 'slave' monitoring happens after the resource
has been demoted
+ High: PE: Prevent failure stickiness underflows (where too many
failures become a _positive_ preference)
+ Medium: Admin: crm_mon - Only complain if the output file could
not be opened
+ Medium: Common: filter_action_parameters - enable legacy handling
only for older versions
+ Medium: PE: Bug N:385265 - The failure stickiness of group
children is ignored until it reaches -INFINITY
+ Medium: PE: Implement master and clone colocation by exlcuding
nodes rather than setting one's score to INFINITY (similar to cs:
756afc42dc51)
+ Medium: TE: Bug LF:1875 - Correctly find actions to cancel when
their node leaves the cluster
