Query now throws no warnings under strict mode in Firefox (ticket #922). In fixing this, revision [1771] was discovered and reverted (no API changes are being added in at this time), and a couple un-functioning test cases were fixed (array comparisions were being done for objects).

Removed support for the XPath [n] - we weren't doing it right, and it would actually require a lot of code to "do it right" (much more than what the feature is immediately worth). See ticket #995.

Added support for finding elements that have underscores in their name (along with other allowed characters). Fix for ticket #1084.

Add hook for modifying the merge behavior of $.extend. Specifically, and time there is a collision between the target and mergee this function is called to resolve it.

Remove XMLHttpRequest shadowing, instead decide at runtime whether to create an ActiveXObject or the XMLHttpRequest, potentially fixing #963

Added a number of additional speed gains (we now hold our own against Dojo and DOMQuery), touched up some of the selector code, fixed some minor bugs, fixed a bug with triggerEvent in Opera, fixed some more test case bugs.

Opera is also vulnerable to the getElementById-returning-name issue, fixed it there as well. Also had to tweak the UTF8 regexps to work in Safari (Safari doesn't support \uXXXX in RegExps, lame.)

Cleaned up a lot of the test suite - reorganized and renamed tests. Added a new triggerEvent() method to the test runner to help us better test actual event interactions.
