1. New data types, from the user point of view:

   BINARY(N) and VARBIBARY(N)
2. More 4.0 compatibility and more BINARY keyword consistency:
2a. CREATE TABLE a (a CHAR(N) BINARY) 
    is now synonym for
    CREATE TABLE a (a CHAR(N) COLLATE xxxx_bin)
2b. SELECT BINARY x
    is still synonin for
    SELECT x COLLATE xxxxx_bin.
