MySQL/Galera Demo-2 released without further ado

Our test session with Demo-2 release got somewhat prolonged. We faced few issues, mostly due to merging with MySQL head (5.1.31 - 5.1.32) and we needed to feed fixes through R&D cycle, which inevitably takes some time.

Merging with MySQL 5.1.31 and 5.1.32 Releases

Our MySQL integration code (wsrep: https://launchpad.net/codership-mysql) was lagging behind from MySQL 5.1 release cycle and we needed to catch up eventually. MySQL/Galera Demo-1 was built on top of MySQL 5.1.30 and since then both 5.1.31 and 5.1.32 have been published.

GLB 0.6.2 released
