When log messages are written with both address and port information, IPv6
addresses can cause confusion if the normal address:port formatting is
used. The RFC 3986 suggests that all IPv6 addresses are expressed as a
bracket enclosed address optionally followed by the port that is separate
from the address by a colon.
In practice, the "all interfaces" address and port number 3306 can be
written in IPv4 numbers-and-dots notation as 0.0.0.0:3306 and in IPv6
notation as [::]:3306. Using the latter format in log messages keeps the
output consistent with all types of addresses.
The details of the standard can be found at the following addresses:

|
|
|
|
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.
|
|
|
|
