[Pacemaker] RC1 announcement for Heartbeat 3.0.5

[Lars Ellenberg]

About two month ago, dealing with a bug report of some paying customer,
I fixed some long standing bugs in the heartbeat communication layer
that caused heartbeat to segfault, and other bad behaviour.

These bugs where triggered by "misbehaving" API clients,
respectively massive packet loss on the communication links,
and have been present basically since inception.

The changelog does not really look spectacular,
but is supposed to very much improve the robustness of the heartbeat
communication stack if you experience massive packet loss on all
channels, for whatever reason.

As these are fixes affect the heartbeat messaging core,
they are relevant for both Pacemaker and "haresources" style clusters.

Changelog:
  - do not request retransmission of lost messages from dead members
  - fix segfault due to recursion in api_remove_client_pid
  - properly cleanup pending delayed rexmit requests before reset of seqtrack
  - create HA_RSCTMP on start, if necessary

Tarball:
http://hg.linux-ha.org/heartbeat-STABLE_3_0/archive/STABLE-3.0.5-rc1.tar.bz2

We expect no further changes.
If you want to give it a whirl on your test clusters, please do so,
and report any issues before Wednesday June 15,
when we expect to cut the 3.0.5 final.

Enjoy!
