jQuery celebrated its third birthday Wednesday with the release of the brand-new 1.3 version. This latest release includes a bunch of cool new stuff which has already been discussed to death elsewhere. To me, however, the most interesting aspect of jQuery 1.3 is the movement of former plugin functionality to the core library.
Live events are a new twist on the venerable, and indispensable, Live Query plugin, while the upgraded, more granular effects queues were previously tackled by add-on authors. IMHO, this kind of migration is A Good Thing, providing greater parity with other core JavaScript and effects libraries (such as Scriptaculous’s FX queue) while offering compelling feature differentiation (event binding throughout the full lifecycle of an Ajax page).


[...] I’m as geeked about jQuery’s 1.3 release as the next developer. But I’m even more excited about the new API browser developed by Remy Sharp and available here. [...]
Little bit of a correction,
.live() has a method name that is a nod to livequery and accomplishes a similar goal, but in a completely different fashion.
It’s actually more of a migration of the event delegation (delegate) plugin into the core, but not the true one. (Livequery, on the other hand, continually polls the dom for changes and reapplies event handlers)
Just FYI.
