• Fixed a bug that made OPTIMIZE TABLE to corrupt the table
  under some rare circumstances.

• Fixed the bug that caused IGNORE INDEX and USE INDEX sometimes to be ignored.
  
• Fixed rare core dump problem in complicated GROUP BY queries that didn't return any result.
  
• Fixed a bug where MATCH ... AGAINST () >=0 was treated as if it was >.
  
• One can create TEMPORARY MERGE tables now.
  
• Fixed that --core-file works on Linux (at least on kernel 2.4.18).
  
• Fixed a problem with BDB and ALTER TABLE.
  
• Fixed reference to freed memory when doing complicated GROUP BY ... ORDER BY queries. Symptom was that mysqld died in function send_fields.
  
• Allocate heap rows in smaller blocks to get better memory usage.
  
• Fixed memory allocation bug when storing BLOB values in internal temporary tables used for some (unlikely) GROUP BY queries.
  
• Fixed a bug in key optimizing handling where the expression WHERE column_name = key_column_name was calculated as true for NULL values.
  
• Fixed core dump bug when doing LEFT JOIN ... WHERE key_column=NULL.
  
• Fixed MyISAM crash when using dynamic-row tables with huge numbers of packed fields.
