The MariaDB project would like to announce the availability of MariaDB 5.3.2-beta, the latest addition to our growing lineup of supported software. MariaDB 5.3.2-beta is a bug-fix update to the previous 5.3.1 and 5.3.0 betas.

== About MariaDB 5.3
The MariaDB 5.3 series introduces many new features, includes MariaDB 5.2, and is based on MySQL 5.1. Some highlights of new features in MariaDB 5.3 include:

– subquery optimizations that finally make subqueries usable
– many optimizer changes, including Classic Hash Join, Batched Key Access, a new implementation of Multi-Range-Read optimizations as well as Index Condition Pushdown
– NoSQL-style interfaces via the HandlerSocket plugin as well as dynamic columns
– group commit in XtraDB when the binary log is enabled
– Microsoft Windows performance improvements

These are just some of the highlights, and for a more complete list of changes, please read the What is MariaDB 5.3 page:

== About MariaDB 5.3.2-beta

In the MariaDB 5.3.2-beta there are a couple of changes compared to previous 5.3 releases:

=== User Feedback plugin

MariaDB 5.3.2-beta introduces the User Feedback plugin. This plugin is disabled by default. If enabled, it submits anonymous basic MariaDB usage information. This information will be used by the developers to track trends in MariaDB usage to better guide development efforts.

If you would like to help make MariaDB better, please add –plugin-load=feedback.so to your my.cnf file! On Windows, add  “feedback=ON” to your my.ini file, or click the checkbox during
installation of the MSI package.

See http://kb.askmonty.org/en/user-feedback-plugin for more information.

=== Subquery Cache now on by default

Starting in MariaDB 5.3.2-beta, the Subquery cache is on by default. In previous versions of MariaDB the cache was off by default.

The goal of the subquery cache is to optimize the evaluation of correlated subqueries by storing results together with correlation parameters in a cache and avoiding re-execution of the subquery in cases where the result is already in the cache.

See http://kb.askmonty.org/en/subquery-cache for more information.
