In case you haven’t run around the web recently you may or may not have noticed jQuery 1.4 has just hit the web. The new release has a large list of improvements on features, speed increases as well as is highly backwards compatible which means most people can upgrade without any real hassles.

Instead of re-writing all the new features and speed improvements jump on the official release site for more details:

Be sure to read the backwards incompatibilities at the bottom just to make sure nothing will break when you upgrade.

I’ll post a review once I’ve had a chance to put it through it’s paces properly.
