Changed Features

Formatting of IP Addresses and Ports

All messaging that contains both the address and the port are now printed in an IPv6 compatible format. The output uses the format defined in RFC 3986 and STD 66.

In practice this means that the address is enclosed by brackets. The port is separated from the address by a colon. Here is an example of the new format:

[192.168.0.201]:3306
[fe80::fa16:54ff:fe8f:7e56]:3306
[localhost]:3306

The first is an IPv4 address, the second an IPv6 address and the last one is a hostname. All of the addresses use port 3306.

Cache

  • The storage storage_inmemory is now the default, so the parameter storage no longer need to be set explicitly.

Improved Wildcard Matching

The MySQLAuth module now supports all types of wildcards for both IP addresses as well as hostnames.

Configurable Connector-C Plugin Directory

The Connector-C used by MaxScale can now be configured to load authentication plugins from a specific directory with the new connector_plugindir parameter. Read the Configuration Guide for more details about this new parameter.

New Features

IPv6 Support

MaxScale now supports IPv6 connections on both the client and backend side as well as being able to listen on IPv6 addresses.
