Release notes 

This is the first release in a 3.x branch which is a major upgrade from 2.x. It introduces
- new writeset format optimized for performance and reduced memory usage.
- 128-bit writeset checksums, checked every time before writeset is applied, so that corruption cannot sneak in neither on disk, nor in transfer.
- hardware accelerated CRC32-C algorithm for network packets (and ability to turn it off completely). Parameter: socket.checksum.
- improved handling of preordered (read: master-slave replication) events, that preserves original event ID and offers better throughput.
- ability to divide cluster into segments with minimized communication between them to minimize network traffic over WAN. Parameter: gmcast.segment.

Plus all features from 2.7 release.

THIS IS A BETA QUALITY RELEASE FOR TESTING PURPOSES. NOT RECOMMENDED FOR PRODUCTION YET.

UPGRADING from 2.x: Since 3.x introduces a number of new configuration variables rolling upgrade will need to take 2 rounds: 1st round - software upgrade with old configuration. 2nd round - configuration upgrade where new options can be utilized. For compatibility with 2.x all 3.x nodes must have "socket.checksum=1" in wsrep provider options.
