I have custom menus on my site which utilize is_tax($taxonomy, $term(s)) to identify whether users are on specific taxonomy archive pages. A "current" class is added to the menu item if the taxonomy/taxonomy term matches the menu item (allowing me to highlight it).
All was working great before the upgrade to 3.5, but my menu highlights no longer function after. I reverted my test site to 3.4.2, and everything functioned again.
Has is_tax() been depreciated? If so, what is the proper conditional statement to identify specific taxonomy archive pages? Thanks!
