What's new in MySQL 5.1.54
Bugs fixed in MySQL 5.1.54 (26 November 2010)
Functionality added or changed:
- Support for the IBMDB2I storage engine has been removed. (Bug#58079)
- The pstack library was nonfunctional and has been removed, along with the --with-pstack option for configure. The --enable-pstack option for mysqld is deprecated and will be removed in MySQL 5.5. (Bug#57210)

Bugs fixed:
- Performance: InnoDB Storage Engine: Improved concurrency when several ANALYZE TABLE or SHOW TABLE STATUS statements are run simultaneously for InnoDB tables. (Bug#53046)
- InnoDB Storage Engine: For an InnoDB table created with ROW_FORMAT=COMPRESSED or ROW_FORMAT=DYNAMIC, a query using the READ UNCOMMITTED isolation level could cause the server to stop with an assertion error, if BLOB or other large columns that use off-page storage were being inserted at the same time. (Bug#57799)
- Partitioning: An INSERT ... ON DUPLICATE KEY UPDATE column = 0 statement on an AUTO_INCREMENT column caused the debug server to crash. (Bug#57890)
- Several compilation problems were fixed. (Bug#57992, Bug#57993, Bug#57994, Bug#57995, Bug#57996, Bug#57997, Bug#58057)
- Passing a string that was not null-terminated to UpdateXML() or ExtractValue() caused the server to fail with an assertion. (Bug#57279)
- Queries executed using the Index Merge access method and a temporary file could return incorrect results. (Bug#56862)
- The find_files() function used by SHOW statements performed redundant and unnecessary memory allocation. (Bug#51208)
