This brings up a question for the Maria dev team-what are your plans, if any, for replication support in MariaDB? In particular, are there any plans that would affect binlog formats?
So far we don't have any planned or in-development features that would have an effect on replication or binlog format. MariaDB's replication is expected to be the same as MySQL replication.

We do however plan to fix issues and bugs in the current replication and apply some of the important patches that are floating around.
