New Product Releases

New Release of MySQL 5.1.26 (Release Candidate)

We are proud to present to you the MySQL Server 5.1.25-rc release, a new "release candidate" version of the popular open source database. Bear in mind that this is still a "candidate" release, and as with any other pre-production release, caution should be taken when installing on production level systems or systems with critical data. Fixes include:

- Replication: Performing an insert on a table having an AUTO_INCREMENT column and an INSERT trigger that was being replicated from a master running MySQL 5.0 or any version of MySQL 5.1 up to and including MySQL 5.1.11 to a slave running MySQL 5.1.12 or later caused the replication slave to crash. (Bug#36443)

- Row-based replication broke for utf8 CHAR columns longer than 85 characters. (Bug#37426)

- NOT IN subqueries that selected MIN() or MAX() values but produced an empty result could cause a server crash. (Bug#37004)

New Release of MySQL 6.0.5 (Alpha)

MySQL 6.0.5-alpha, a new version of the MySQL database system including the Falcon transactional storage engine, has been released. Changes include:

- Incompatible Change: In MySQL 5.1.6, when log tables were implemented, the default log destination for the general query and slow query log was TABLE. This default has been changed to FILE, which is compatible with MySQL 5.0, but incompatible with earlier releases of MySQL 5.1 from 5.1.6 to 5.1.20.

- Incompatible Change: The server now includes dtoa, a library for conversion between strings and numbers by David M. Gay. In MySQL, this library provides the basis for improved conversion between string or DECIMAL values and approximate-value (FLOAT/DOUBLE) numbers.

- Important Change: Security Fix: It was possible to circumvent privileges through the creation of MyISAM tables employing the DATA DIRECTORY and INDEX DIRECTORY options to overwrite existing table files in the MySQL data directory.

- Important Change: Security Enhancement: On Windows Vista and Windows Server 2008, a user without administrative privileges does not have write permissions to the Program Files directory where MySQL and the associated data files are normally installed.

New Release of MySQL Workbench 5.0.23 (GA)

The MySQL Developer Tools team is working on version 5.1 in parallel while we keep constantly improving version 5.0 and fixing remaining bugs. 26 bugs have been fixed since the last release. As an improvement, most common parameters of the application state (Window position, size, etc) are now stored/restored properly.

PlanetMySQL Blog: Differences Between innodb_data_file_path and innodb_file_per_table
