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. Changes include:

• Incompatible Change: A change has been made to the way that the server handles prepared statements. This affects prepared statements processed at the SQL level (using the PREPARE statement) and those processed using the binary client-server protocol (using the mysql_stmt_prepare() C API function).
• Important Change: Some changes were made to CHECK TABLE ... FOR UPGRADE and REPAIR TABLE with respect to detection and handling of tables with incompatible .frm files (files created with a different version of the MySQL server).
• Replication: CREATE PROCEDURE and CREATE FUNCTION statements containing extended comments were not written to the binary log correctly, causing parse errors on the slave.
