Functionality added or changed:
Incompatible Change:
The InnoDB
storage engine no longer ignores
trailing spaces when comparing
BINARY
or
VARBINARY
column values. This
means that (for example) the binary values
'a'
and 'a '
are now
regarded as unequal any time they are
compared, as they are in MyISAM
tables.
See The BINARY
and VARBINARY
Types for more information
about the BINARY
and
VARBINARY
types.
