jQuery – Version 1.4

Eine neue Version der jQuery Lib ist da mit über 200 Bugfixes!
Folgende Punkte freuen mich ganz besonders:

• .text() works on text and CDATA nodes
• Event Multi-binding
• New events: `focusin` and `focusout`
• jQuery.isEmptyObject()

ausprobiert habe ich es bis dato noch nicht, aber das kommt schon noch!

Attributes:

• The performance of .css() and .attr() has been improved.

Core:

• Quick Element Construction

Effects:

• Per-property Easing

Events:

• All Events Can Be Live Events
• live/die now work with context

• Performance of .remove() and .empty() has seen over a 4x speed increase.

Offset:

Traversing:

• .closest(filter, DOMElement)

Utilities:

• jQuery.unique()

Miscellaneous:

• jQuery.browser is now engine-centric
• Better support for applets
• No longer use arguments.callee
• Now use Closure Compiler instead of YUI Min

Internal Reorganization:

• The old ‘core.js’ file has been split apart into ‘attribute.js’, ‘css.js’, ‘data.js’, ‘manipulation.js’, ‘traversing.js’, and ‘queue.js’.
• The ready event has been moved into core.js (as it’s a fundamental part of jQuery itself).
• The majority of core matches the new jQuery Core Style Guidelines.
• The logic for CSS and attributes have been split and aren’t so intertwined anymore.
