The following symbols are now reserved words: TIME, DATE, TIMESTAMP, TEXT, BIT, ENUM, NO, ACTION, CHECK, YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, STATUS, VARIABLES.
Setting a TIMESTAMP to NULL in LOAD DATA INFILE ... didn't set the current time for the TIMESTAMP.
Fix BETWEEN to recognize binary strings. Now BETWEEN is case-sensitive.

Added variables command to mysqladmin.
A lot of small changes to the binary releases.
Fixed a bug in the new protocol from MySQL Version 3.21.20.
