Release notes 

2.0 is the fist release in 2.x series which introduces Incremental State Transfer and shared key certification.

Incremental State Transfer (IST) is a non-blocking state transfer which substitutes State Snapshot Transfer (SST) in cases when node can synchronise with the cluster by replaying missing transactions. IST makes node remerge very fast in many situations. 'gcache.size' parameter (default: 128M) determines the amount of transactions that can be replayed.

Galera 2.0 is using wsrep API v23 and is binary incompatible with previous versions.

Galera 2.0 is protocol backward compatible with 1.1 and 1.2 versions: 2.0 node can be added to 1.1 cluster, but 1.1 node cannot be added to 2.0 cluster. New features become available only after full cluster upgrade.
