The "recent posts" link (also known, in Drupal lingo, as the "tracker") has now been replaced with an enhanced version (called "xtracker" but still listed as "recent posts" in the navigation). The main difference? You can sort data by any column. This makes it easier to see what's new on the site.
Both versions have been there for the past few weeks, but now that I'm happy with this improved version, I disabled the old one and moved the new one into its place in the navigation.
