The 14 Days of jQuery brings you fourteen consecutive days of new releases to celebrate the release of jQuery 1.4. Each day they will publish some fresh videos and announcements — there’ll be code releases, project-related updates, and jQuery UI goodness, among other things.

In addition to the announcements, they will also be releasing a set of videos over the 14 days with talks and tutorials relating the jQuery 1.4 release and other general jQuery topics. You’ll want to check back at The 14 Days of jQuery every day during the two weeks to see what’s new, or sign up to be notified via email. Think of it like an online conference, only longer, freer, and with a bit of mystery and suspense!
