Added support for the event object properties relatedTarget, metaKey, which, and charCode. Fixes bug #1204.

Added fixes for bug #1052. Fixes the problems with animation chaining (and problems with toggling). Also, removed toggling from jQuery.fx (it's now handled in .animate() instead).

Added some improvements to how the browser version is determined, based upon the suggestions of 'hobbit' in [1101].

We're not adding new selector features in until a new full release. Please discuss features like this in the dev mailing list, and in the bug tracker, before committing code.

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.
