This document describes the changes in release 2.3.1, when compared to release 2.3.0.

For any problems you encounter, please consider submitting a bug report at Jira.

Changed Features

Binlog Router

Secondary masters can now be specified also when file + position based replication is used. Earlier it was possible only in conjunction with GTID based replication.

`mmmon` and `ndbclustermon`

Both of these modules have been deprecated and will be removed in a future release. The functionality in mmmon has been largely obsoleted by the advancements in mariadbmon. The ndbclustermon is largely obsolete due to the fact that there are virtually no users who use it.

Deprecated options

The following configuration file options have been deprecated and will be removed in 2.4.

Global section

non_blocking_polls, ignored.
poll_sleep, ignored.
thread_stack_size, ignored.

Services and Monitors

passwd, replaced with password.

MaxAdmin

The commands set pollsleep and set nbpolls have been deprecated and will be removed in 2.4.

New Features

MaxCtrl

There is now a new command classify <statement> using which it can be checked if and how MaxScale classifies a specific statement. This feature can be used for debugging, if there is suspicion that MaxScale sends a particular statement to the wrong server (e.g. to a slave when it should be sent to the master).
