The format of xtrabackup_galera_info was missing the ‘:’ separator between the values of wsrep_local_state_uuid and wsrep_last_committed. Bug fixed #1181222.
When backing up a server that is not a replication slave with the innobackupex --slave-info option, innobackupex failed with a fatal error. Replaced the fatal error with a diagnostic message about innobackupex --slave-info being ignored in such a case. Bug fixed #1180662.
Low values for wait_timeout on the server could cause server to close the connection while backup is being taken. Fixed by setting the bigger value for wait_timeout option on the server to prevent server from closing connections if the global wait_timeout value is set too low. Bug fixed #1180922.
Other bug fixes: bug fixed #1177182.
