Is it just me or are excluded_categories no longer working in WP 2.5? I have a theme working fine with it in 2.3 but totally ignoring the 4th parameter of next_post_link and previous_post_link in 2.5.
Example of code that works in 2.3 but not 2.5 (the excluded category parameter is ignored in 2.5)...
previous_post_link('%link', '« ', FALSE, '1');
next_post_link('%link', '»', FALSE, '1');
