Great news from the jQuery Team with a release of the new jQuery 1.3 Javascript Library. Per the team:
“First, we have an excellent new release of jQuery ready for you to enjoy. The big features of this release 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. “
I like the graphs that show the improvements in performance. This being just one:
