MySQL text limits

Today’s  discovery: MySQL TEXT fields have a limit of 65,000 bytes. If you insert anything larger than that in to a normal TEXT field mySQL will silently truncate your data without telling you (meaning software checks are probably a good idea). MEDIUMTEXT will store 16 million characters and LONGTEXT can handle over 4 trillion, but this information does not appear to be readily available in the online mySQL manual. Something to bare in mind when designing database applications.
