The version 1.3.2 of jQuery is finally out. It solves several bugs and improves the performance in some parts of the code.
The list of most important changes are:
- Elements are now returned in document order.
- .live() can now prevent bubbling.
- :visible/:hidden are now significantly faster.
- As are all the width/height methods.
- Selectors are much faster in Internet Explorer.
- appendTo/etc. have had a slight API tweak.
