Following closely on the heels of the MariaDB 5.3.4-rc release a couple of weeks ago, the MariaDB project is pleased to announce the immediate availability of MariaDB 5.3.5!

MariaDB 5.3.5 is the first stable (GA) release in the 5.3 series. Details and downloads are available from the following links:

(Debian and Ubuntu packages are available from our mirrored apt repositories. A sources.list generator is available.)

About MariaDB 5.3

The MariaDB 5.3 series introduces many new features, includes MariaDB
5.2, and is based on MariaDB 5.1 & 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 see the What is MariaDB 5.3 page.

We are pleased to announce the immediate availability of MariaDB 5.5.20-alpha. MariaDB 5.5.20 is the first Alpha release in the 5.5 series. We hope to follow it up soon with a beta 5.5 release.

MariaDB 5.5.20-alpha is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. This is the first 5.5-based release, and we are releasing it now, intentionally without any extra features (and with it missing some planned features) to get it into the hands of any who might want to test it. Extra features planned for MariaDB 5.5 will be pushed into future releases.

As with any alpha release, MariaDB 5.5.20-alpha should not be used on production systems.

The Release Notes page has some notes on the release. There is also a Changelog available for those who are interested.

Sources, binaries and package downloads are available from our network of MariaDB mirrors. Debian and Ubuntu packages are available from our mirrored apt repositories. We have created a sources.list generator for creating sources.list entries.

About MariaDB 5.5

The MariaDB 5.5 series is the combination of MariaDB 5.3 and MySQL 5.5.

Please see the What is MariaDB 5.5 page for details.

We have lately been talking about some upcoming features that we feel are important to MariaDB users, because the corresponding ones that will be provided with MySQL will be incompatible with MariaDB and closed source.

We’re happy to announce the following:

  • The next version of MariaDB, version 5.2.10 will include an open source PAM Authentication Plugin. MariaDB 5.2.10 is scheduled for release next week.
  • A Windows Authentication Plugin is in development and QA currently and will be part of MariaDB 5.2.11, which is scheduled for release before Christmas.
  • MariaDB 5.5 will include both of the above plugins and an open source thread pool implementation. The soon-to-be-launched first version however will not include the thread pool.

Stay tuned for more information as soon as we start launching the above features.

Mission critical services relying on MariaDB should be aware that SkySQL has familiarized themselves with the new features and are ready to support all of the above options.
