Subject: Galera 2.2 Release Candidate

This is a new maintenance RC in 2.x series which fixes three important bugs:
* causal reads guarantee violation at cluster partitioning.
* exclusive keys didn't produce dependency on shared keys.
* IST was not working across different EC2 accessibility zones (resolved
global DNS names to local IPs).

It also adds two interesting features:
* wsrep_incoming_addresses status variable contains a comma-separated list
of incoming (client) addresses in the cluster component. This can be used
for example for polling by load balancer.
* ability to specify several node addresses in gcomm:// URL. This is a
successor to "infamous" wsrep_urls parameter for mysqld_safe and is a
preferred way to provide several node addresses to Galera. (BEWARE!
wsrep_urls takes precedence so make sure to eliminate it from my.cnf)

Since this release contains two new features, we decided to make a release
candidate first to gain some feedback. Provided there are no complains this
code will be promoted to final release in a couple of weeks.
