The document discusses jQuery 1.9, 2.0, and the future of jQuery, noting that jQuery 2.0 drops support for older browsers like IE6-8 but is 12% smaller, and introduces 12 optionally excludable modules; it promises that jQuery 1.X will be supported as long as older IE browsers are relevant and that API equivalence will be maintained between 1.X and 2.X versions; and it invites attendees to join and contribute to the jQuery community.
