Theme not working in Wp 2.5

I’ve been trying to get my WP theme working in 2.5. It works fine in 2.3 but some things break in 2.5. I’ve fixed most of them in CSS but I still have one issue left. I’ve narrowed it down to one line of PHP:

<div class=”posts<?php if(is_home() && $post==$posts[0] && !is_paged()) echo ‘End’;?>”></div>

The echo is not getting passed and I’m pretty sure its due to the “$post==$posts[0]” part.

Anyone know what changed that would cause this and any workarounds for it?

Thanks,
Alec
