Another somewhat thin release, but as you may have read, some of the team has been moving around a bit, but with things settling down, expect more goodness to come.  Also, a special thanks to Henrik Ingo for taking the lead on several community tasks - his efforts and insights are a most welcome addition to the project!

In this release:

• json interface merged

• bug fixes
• continued code refactoring and improvement

Drizzle source tarball version 2011.03.13 has been released.  This is a GA release (and just in time for the ides of March) >: )

* Apologies for any confusion with version 2011.03.12 (see the url for this entry...) and announcements - there was an issue with the release process that necessitated cutting another tarball.  2011.03.13 is good to go

It's been a long and crazy road to get to this point and the team would like to thank everyone that has helped us get here.  Every patch, bug report, and thought-provoking question has been invaluable in getting Drizzle this solid.

For quick summaries of what has been going on with the team, please check out Andrew Hutching's terrific 'Last Week In Drizzle' series

For a general rundown of how we differ from MySQL, see here

Here is a partial list of what you can find inside:

• Documentation is sphinx-based and available in-tree or online.  It should be noted that they are licensed under Creative Commons!
• Replication solutions will be log based.  Both file-based and innodb-table based versions of the log are available and have been heavily tested / validated.
• Native replication available via the slave plugin.  This solution utilizes the innodb-based replication log and has been subjected to significant testing.  Check out a simple example here.  You can check out David Shrewsbury's replication related blog posts here
• Easy migration from MySQL systems via the Drizzledump tool.
• Drizzleadmin tool - used to bypass the protocol’s max-connections setting to do tasks such as killing queries or clients.
• libdrizzle is included in the tree (no longer a separate project) and is BSD licensed
• ANSI-compliant INFORMATION_SCHEMA
• DATA_DICTIONARY for custom, Drizzle-specific tables and data
• Innodb tables by default
• MyISAM available (temporary tables)
• Removed archive, blackhole, csv, and other engines (these can be reintroduced if faced with enough demand).
• HailDB engine = embedded Innodb, but better
• Pluggable authentication
• SQLAlchemy integration - we now pass their test suite and use it as part of our build and test system
• Significant performance improvements
• Initial work for catalogs
• And tons more!

Please consult the documentation as a first resource.  Contact us via our mailing lists, launchpad, or IRC if you have any questions

Drizzle source tarball, version 2011.03.11 has been released.  For those of you counting at home, that makes two...two RC's...ah ah hah! : )

While the original plan was to release a GA today, there are still some features we wanted to test more thoroughly before calling things good.  The plan is to have a GA release on 3/14.  The code is amazingly solid at this point and we feel confident in asking people to start to use it seriously.  Please help us test the heck out of Drizzle to get ready for GA!

If you want the latest and greatest Drizzle news, we highly recommend LinuxJedi's Last Week in Drizzle feature.

Most of the work in this release has been polish, polish, and more polish as we near our first GA!

In this release:

• New native replication solution - the slave plugin!  This allows a Drizzle server to replicate from a master that is using the innodb replication log.  Read more about this here and here
• Because you asked for it - MySQL BIT operators are back (thanks to Brian Aker for this)
• Continued work on system variables
• Continued work on catalogs
• Continued work on SQLAlchemy dialect / Drizzle interoperability
• Fixes for various performance regressions
• Continued work on documentation
• random query generator integration with new test runner
• Over 30 bug fixes

Drizzle source tarball, version 2011.02.10 has been released.  We are proud to announce that this is an RC (Release Candidate) release.

With a GA not too far away, we would greatly appreciate folks helping us to check things out.  We have been working hard on a number of features and would like your feedback.

• New BOOLEAN type
• New UUID type
• Drizzle can now fork to background via --daemon: https://bugs.launchpad.net/drizzle/+bug/565053
• NOTE: Cartesian joins no longer work and will throw an error - this might break some applications.  They can still be achieved via CROSS JOIN or through the use of a WHERE clause.  It was put in place to prevent runaway queries.
• Innodb transaction log is working and tested.  Both the file-based and innodb-based logs are available.
• Continued work on system variables
• Removed lint.am file as Drizzle no longer uses it
• Continued work on catalogs
• Continued work on our documentation
• Various other bug fixes

• various updates to our online documentation
• various other bug fixes
