jQuery 1.4.3 Release Candidate 1 Released

jQuery 1.4.3 Release Candidate 1 is released! This is the first release candidate of jQuery 1.4.3. The code is stable (passing all tests in all browsers we support), feature-complete (we’re no longer accepting new features for the release), and needs to be tested in live applications.
Grab the code:

NOTE: If you’re using jQuery 1.4.3rc1 and you run into an error please make sure that you’re using the regular version of the code, it’ll make it easier to spot where the error is occurring.
How can I help?
To start, try dropping the above un-minified version of jQuery 1.4.3rc1 into a live application that you’re running. If you hit an exception or some weirdness occurs immediately login to the bug tracker and file a bug. Be sure to mention that you hit the bug in jQuery 1.4.3rc1!
We’ll be closely monitoring the bug reports that come in and will work hard to fix any inconsistencies between jQuery 1.4.2 and jQuery 1.4.3.
What to Watch For
There are a few areas in jQuery that have seen extensive changes since 1.4.2 was released:

  • .css() and related css-handling methods were all overhauled.
  • Logic for determining element visibility and toggling of display in animation code.
  • Much of the traversing logic has been improved and changed (is, filter, closest, find).

Full details concerning the release are forthcoming – for now we just need your help in catch regressions.
With your input we should be able to produce a solid release. Right now we’re looking to get the final 1.4.3 release out in time for the jQuery Conference in Boston this next weekend. Thanks for your help in reviewing jQuery 1.4.3rc1!
