New jQuery release version 1.3

Yesterday jQuery released their new version, number 1.3. They did a lot af changes / bugfixing, performance improvements.

The big features are:

  • Sizzle: A sizzlin’ hot CSS selector engine.
  • Live Events: Event delegation with a jQuery twist.
  • jQuery Event Overhaul: Completely rewired to simplify event handling.
  • HTML Injection Rewrite: Lightning-fast HTML appending.
  • Offset Rewrite: Super-quick position calculation.
  • No More Browser Sniffing: Using feature detection to help jQuery last for many more years to come.

They did a pretty good job on the performance:

Selector performance, 49% faster:

Delegation filtering performance, 30x times faster:


Element insertion performance, 6x faster:
 

Offset rewrite, 3x times faster:


There is also a new API browser released with the following features:

  • All the latest jQuery and jQuery UI documentation.
  • The ability to mark pages as favorites for those pages you keep wanting to return to.
  • Syntax highlighting in the code examples
  • Live running of examples within the browser
  • Links to edit and experiment with the code examples

Thanks for posting this, But this is a duplication of the official release notes - so i ask why?

i really don't like to to get 100 post every day on the same subject.

I even think we need a way to know that there us a duplicate note that we can ignore / specifically read
