# MariaDB MaxScale 2.1.2 Release Notes -- 2017-04-03 Release 2.1.2 is a Beta release. This document describes the changes in release 2.1.2, when compared to release [2.1.1](MaxScale-2.1.1-Release-Notes.md). If you are upgrading from release 2.0, please also read the following release notes: [2.1.1](./MaxScale-2.1.1-Release-Notes.md) [2.1.0](./MaxScale-2.1.0-Release-Notes.md) For any problems you encounter, please consider submitting a bug report at [Jira](https://jira.mariadb.org). ## 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] (https://www.ietf.org/rfc/rfc3986.txt) and [STD 66] (https://www.rfc-editor.org/std/std66.txt). 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](../Getting-Started/Configuration-Guide.md) 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. ## Bug fixes [Here is a list of bugs fixed since the release of MaxScale 2.1.1.](https://jira.mariadb.org/issues/?jql=project%20%3D%20MXS%20AND%20issuetype%20%3D%20Bug%20AND%20resolution%20in%20(Fixed%2C%20Done)%20AND%20fixVersion%20%3D%202.1.2%20AND%20fixVersion%20NOT%20IN%20(2.1.1)) * [MXS-1032](https://jira.mariadb.org/browse/MXS-1032) missing mysql_clear_password.so plugin ## Known Issues and Limitations There are some limitations and known issues within this version of MaxScale.
