# MariaDB MaxScale 2.3.1 Release Notes
|
|
|
|
Release 2.3.1 is a Beta release.
|
|
|
|
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](https://jira.mariadb.org).
|
|
|
|
## 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).
|
|
|
|
