MariaDB MaxScale 1.4 Release Notes

This document describes the changes in release 1.4, when compared to release 1.3.0.

1.4.0

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

New Features

Firewall Filter

SSL

Client-side SSL support has been in MaxScale for some time, but has been known to have been unstable. In 1.4.0, client side SSL is now believed to be stable and fully usable.

POSIX Extended Regular Expression Syntax

The qlafilter, the topfilter and the namedserverfilter now accept extended as a parameter, which enables the POSIX Extended Regular Expression syntax.

Removed Features

MaxScale no longer supports SSLv3.
