Errors in theme review

Hey, there are a few errors that I’m getting when I submit a theme here, and I’m not quite sure how to fix them. Here’s the first one:

DEPRECATED CALL: Used in wp-includes/general-template.php on line 372.
The home option is deprecated for the family of bloginfo() functions. Use the url option instead.
Deprecated in version 2.2.

If you can help at all, I’d be grateful. Thanks.
