Smarter Navigation: Version 1.2

Two template tags have been added:

If you have posts in multiple categories, you can use get_referrer_category() to retrieve the category object, based on the referrer url.

get_referrer_url() returns the full URL of the referrer.

Also, there are two extra arguments for previous_post_smart() and next_post_smart(): $in_same_cat and $excluded_categories.

This is how the function prototype looks like:

	$format = '« %link',
	$title = '%title',
	$fallback = true,
	$in_same_cat = false,
	$excluded_categories = ''
