   fix by not adding the ON DELETE/UPDATE clause at all
 * Changed dependency on Digest::SHA1 to the core-bundled Digest::SHA (RT#67989)
 * Support for double quoted and bit strings as default values in MySQL parser
+* Proper handling of CURRENT_TIMESTAMP default values in MySQL parser (RT#65844)
 * Check in MySQL parser to avoid trying to parse a table defined twice in the same
   file as indices (and probably other things) get messed up
 * Workaround for some MySQL quirks on primary key definitions
