Request to replace deprecated functions to the newer ones.

Dear WPMU Default theme developer,

I have a quick question that
1. Can you kindly replace get_themes() to wp_get_themes() since it has been deprecated since v3.4 ?
2. As wp_specialchars() is deprecated since version 2.8! Can you use esc_html() instead ?

I have attached a screenshot for your reference. Feel free to contact me.

Thank you.
