This release is a 'release candidate'. This means that we think it's almost ready for a final release but we don't want to call it a final release until more people have had a chance to test it. This release should be followed by a final release in a few weeks.

5.1.41 RC is based on 5.1.41 and 1.0.4-8.

MariaDB is kept up to date with the latest MySQL release from the same branch.

In most respects MariaDB will work exactly as MySQL; all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

In addition to the differences noted in the MariaDB and release notes, the main differences between MariaDB and MySQL are:

For we have merged in all of the upstream changes from MySQL 5.1.41. The have details of what changes were made upstream by MySQL since 5.1.39

We have included XtraDB 1.0.4-8 in this version of MariaDB. The have details of the changes made to XtraDB since version 1.0.3-6 (the version included with Beta).

We have included PBXT 1.0.09f RC3 in this version of MariaDB.

This is the 3rd RC release of PBXT. It includes a number of bug fixes (some specifically for MariaDB), and 2 features:

• XA/2-Phase commit support

• Online backup native driver for PBXT

The backup uses the MySQL backup API (MySQL 6.0/5.4), and is not yet available in MariaDB.

Release notes since the RC2 version in Beta are as follows:

The FederatedX storage engine replaces the old, not maintained, Federated storage engine.

See also:

Like we did with the 5.1.39 Beta, various changes were made in RC in our desire to fix warnings and eliminate bugs. These included removing or fixing invalid tests, cleaning up the codebase where appropriate, and so on.

We are working on setting up a network which will enable us to test and build binaries on many different platforms. We aim to produce binaries in .tar and package formats for all popular platforms. Right now there are generic Linux binaries, packages for Debian and Ubuntu, RHEL/CentOS, and a Windows executable.

The tarball binaries provided in this release are generic binaries, intended for use on most x86-based Linux systems to quickly try out MariaDB without having to compile the source code. For 5.1.38 they were built on Ubuntu 9.04 systems (linked against libc 2.9), for 5.1.39 and 5.1.41 they were built on Ubuntu 8.04 systems (so older libc works). They should hopefully work on most x86-based Linux systems.

See the MariaDB versus MySQL page for a high-level overview of the differences between MariaDB and MySQL.

MariaDB 5.1.38 Beta is based on MySQL 5.1.38 and XtraDB 1.0.3-6.

MariaDB will be kept up to date with the latest MySQL release from the same branch.

In most respects MariaDB will work exactly as MySQL; all commands, interfaces,libraries and APIs that exist in MySQL also exist in MariaDB.

For 5.1.38, the main differences between MariaDB and MySQL are:

The storage engine version 1.5 (the crash-safe version) is included in the source and binaries by default.

If you use the source, you can of course easily disable the Maria storage engine when configuring .

The new Maria storage engine specific options can be found here:.

replaces InnoDB in the tree.

XtraDB is a drop in replacement of InnoDB (same table formats, no need to convert any data).

XtraDB gives you similar performance improvements for multi-cpu systems in that you can expect from using InnoDB in MySQL 5.4.

See also

The PBXT storage engine version 1.0.08d is included in the source and binaries by default.

Our use of the Maria storage engine enables faster complex queries (queries which normally use disk-based temporary tables).

The storage engine is used for internal temporary tables, which should give you a speedup when doing complex selects. Maria is usually faster for temporary tables when compared to MyISAM because Maria caches row data in memory and normally doesn't have to write the temporary rows to disk.

Limited sets of threads handling all queries.

See:

• Fewer warnings when compiling. We believe that compiler warnings can indicate bugs, and strive toward reduction to 0.

• Fewer bugs. If we see a bug while fixing a warning or cleaning up code, we'll fix it when possible.

• There are some improvements to DBUG code to make its execution faster when debug is compiled in but not used.

• CHECKSUM TABLE now ignores values inNULL fields. This makes CHECKSUM TABLE faster and fixes some cases where the same table definition could give different checksum values depending on row format. The disadvantage is the value is now different compared to other MySQL installations. The new checksum calculation is fixed for all table engines which use the default way to calculate and MyISAM which does the calculation internally. Note: Old MyISAM tables with internal checksum will return the same checksum as before. To fix them to calculate according to new rules you have to do anALTER TABLE. You can use the old ways to calculate checksums by using the option

• MariaDB can handle up to 32 key segments per key (up from 16)

• Added a new handler function: prepare_index_scan() that is called before a key scan is done.

• Added --abort-source-on-error to the mysql client.

• Wrong mutex usage detector. This helps us find and fix deadlocks when taking mutex in inconsistent orders. In MariaDB we have removed several deadlocks which exist in the normal MySQL code.

See the MariaDB versus MySQL page for a high-level overview of the differences between MariaDB and MySQL.

MariaDB 5.1.39 Beta is based on MySQL 5.1.39 and XtraDB 1.0.3-8.

MariaDB is kept up to date with the latest MySQL release from the same branch.

In most respects MariaDB will work exactly as MySQL; all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

The FederatedX storage engine replaces the old, not maintained, Federated storage engine.

See also:

Various changes were made in in our desire to fix warnings and eliminate bugs. These included removing invalid tests, removing unused declarations, cleaning up the codebase where appropriate, and so on.

For we have continued our work on improving the test suite. One thing we did was remove unnecessary and confusing 'skipped' messages from mysql-test-run.pl. In mysql-test-run.pl, we auto-generate combinations of replication tests. But this sometimes generates combinations that are meaningless, like running a test that requires row-based replication with statement-based. These superfluous combinations should not be reported as skipped, they should just be deleted. We do keep skip messages resulting from running mysql-test-run.pl in special ways, eg. --mysqld=--binlog-format=statement.

Another thing we did was to remove the ndb suites from the list of default test suites, as we do not support NDB in MariaDB.

We have also done some work on speeding up the test suite. One way we've done this is to insert "--disable_query_log ; begin ; ... commit; --enable_query_log" around all while loops that do inserts.

We've also fixed a race condition in the test system by forcing a restart before maria_showlog_error to get rid of the status from previous connections.

For we switched from using Ubuntu 9.04 and glibc 2.9 for our builds to using Ubuntu 8.04.and glibc 2.7. This should make the binaries more compatible with various Linux systems.

One benefit of our change to using Ubuntu 8.04 and glibc 2.7 for our builds is that we are now able to create CentOS 5 RPM packages. The page has links to both the individual files and to a CentOS 5 YUM repository.

This is a Stable (GA) release. In general this means that there are no known serious bugs, except for those marked as feature requests, that no bugs were fixed since last release that caused a notable code changes, and that we believe the code is ready for general usage (based on bug inflow).

For a description of MariaDB 5.1 see theWhat is MariaDB 5.1 page.

In most respects will work exactly as MySQL: all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

This release is primarily a bug-fix release.

This release includes fixes for the following security vulnerabilities:

• A buffer overflow that can cause a server crash or arbitrary code execution (a variant of )

• DoS - server lockup ()

• DoS - server crash ()

Additionally, it includes all security fixes from MySQL 5.1.67, such as fix for a buffer overflow with stored routines (a variant of ) and fixes for the following vulnerabilities:

This release includes MySQL 5.1.67. See for what changed in MySQL.

The MariaDB project tries to support as many different Operating Systems and Linux Distributions as we can. However, when a distribution or OS stops receiving security and other updates it becomes difficult to freely provide packages for that platform. In such cases, our policy is to deprecate that platform and stop providing binary packages for it.

As of 1 Feb 2013, we will stop building packages for the following:

• Fedora 16 "Verne"

• Debian 5 "Lenny"

• Ubuntu 10.10 "Maverick"

• Ubuntu 11.04 "Natty"

If your chosen Linux Distribution or Operating System is deprecated, packages or support are not completely unavailable. Companies such as and (and others) provide support for all versions of MariaDB back to even very old MySQL versions. This includes packaged binaries. Contact them for more details.

More information on our deprecation policy can be found at:

From the beginning of the MariaDB project in 2009 we've kept all of our old releases online via our network of mirrors. Doing this is great for those few who are interested in old releases, but the disk space required to host all of our old releases is over 130 Gigabytes at present and grows by several gigabytes with each new release. This is too much for some of our mirrors to handle. So, starting with this release our primary mirror will only host the most recent three or four releases in each series (5.5, 10.0, and so on). Mirrors are, of course, free to keep archiving every release, but the primary mirror that they pull from will not.

Old releases do have value, so for those that are interested in old releases, we are setting up a simple, no frills, archive server which will host them. Once the server is up and running, links to archived releases on will point at the archive server. During the transition period, links to some old releases may disappear for a short time, but don't worry, they haven't been deleted, they're just being moved!

Thanks, and enjoy MariaDB!

Several steps were taken during the development of to improve our Windows builds. Steps included the creation of new Windows build slaves, fixes for Windows compiler errors, and better Windows build automation. Windows builds should now be included with every MariaDB release.

A few Ubuntu-specific fixes are included with :

1. A fix for a dependency problem with Ubuntu 10.04 Lucid packages.

2. We now build against the full 10.04 release (we used to build against an alpha version of Ubuntu 10.04).

3. A fix for an Ubuntu issue that appeared when using libmyodbc with mariadb packages.

We've fixed some process issues with the Debian, Ubuntu, and CentOS repositories provided by Open Query. These issues were delaying the latest release from appearing in the repositories. Now releases should show up in the repositories at around the same time a release shows up on the mirrors.

In we've continued to fix bugs and compiler warnings, including bugs in MySQL 5.1.47. The has links to several of the bugs that we have fixed.
