In this talk, the developers behind MySQL Replication walk through
some of the new Replication features of MySQL 5.1 and MySQL 6.0:

- Row-based Replication (5.1) is used for MySQL Cluster replication
and also provides a safer way to replicate non-deterministic
statements.

- Row-based support for mysqlbinlog client (5.1) is used to analyze
the row-based binlog entries.

- Row-based point-in-time recovery (5.1) is used to restore a server
to a particular time point regardless of binlogging format.

- Group position refactoring (5.1) making position handling of
the slave more robust.

- Heartbeating (6.0) is used to manage that the master and slave
connection is always up.

- Semi-synchronous Replication (6.0) is used to ensure that any update
of the master is on the slave before transaction is acknowleged to
the user.

- Backup Integration (6.0) is ensuring that restores on a master does
not corrupt the slave.

- Replication Server Filtering (6.0) ensures that the user can more
easily replicate in a circle.

- Relay log synchronization (6.0) ensures that the slave is restartable
without clearing the relay log in case of crashes.
