With today's update to vBulletin v4.2.1 and a updated template to go with it, a lot of things got improved under the hood mostly but there are also various features built-in now which were previously manually or only partially integrated before. One example is the members who visited today list at the bottom of the forum which we used for years as a 3rd party plugin and which is now built-in. Another good example is a multitude of expandable social bookmarks at the bottom of every post or thread (instead of only a Facebook link at the top) and another example is a fully integrated video player which replaced the old YouTube custom BB code which besides YouTube supports Hulu, Vimeo, Dailymotion, Metacafe, Google and Facebook. The same style video tags (as well as image tags) can be now be used in member signatures as well, and a full list of new features include much more, but is all pretty technical but available if anyone is interested.
