CONVERT() broken in 4.1.1?

This worked in 4.0:

mysql> SELECT CONVERT(NOW(), DATE);
+----------------------+
| CONVERT(NOW(), DATE) |
+----------------------+
| 2004-01-16 18:12:18  |
+----------------------+
1 row in set (0.00 sec)

And even in 4.1.0, but in 4.1.1 it returns:

mysql> SELECT CONVERT(NOW(), DATE);
ERROR 1064: You have an error in your SQL syntax.  Check the manual 
that corresponds to your MySQL server version for the right syntax to 
use near ')' at line 1


However, replacing it with CAST() works fine:

mysql> select CAST(NOW() AS DATE);
+---------------------+
| CAST(NOW() AS DATE) |
+---------------------+
| 2004-01-17          |
+---------------------+
1 row in set (0.00 sec)


However, there is a small difference between 4.0 and 4.1 here. 4.0 
returns it as a date and time, 4.1 returns it as just the date (as 
would be expected?)


Sorry if this has been reported before, but I couldn't find any mention 
of this anywhere.
