Probably not, unless we find someone to pay us for that ;)

Lars has been pushing a few changes now, and wants (hopes) to do a
3.0.6rc1 still in May.

There are no big changes planned, though - heartbeat simply _works_,
and it works so good that hardly any changes are necessary!

The code is stable - so why should we try to mess around in there?


BTW, Heartbeat has a few connection plugins that Corosync is missing
(tipc, rds, hbaping).

-1 for a)
+1 for the rest, of course.


We're building the Pacemaker packages with support for both CCMs,
so that people can switch as necessary "on the fly".
*Please* do the same for Debian.


Regards,

Phil
