jQuery 1.5 Released: AJAX Rewrite, Deferred Objects, jquery.sub(), and Performance

Monday, February 7th, 2011 | Business | by

I’ve been snowed in and busy working, but in the last week jQuery 1.5 was released (on January 31, 2011).

You can see the announcement here:

Right on schedule jQuery 1.5 is ready for consumption!

This release has been a long time coming and has been a real team effort. Please take this opportunity to thank members of the jQuery Team and the jQuery bug triage team for their help in getting this release out the door.

Lots of nice shiny features:

  • Complete AJAX Rewrite – more extensible and consistent code on AJAX queries (.get, .post, etc)
  • Deferred Objects – Allows handling of return values asynchronously.  Multiple event handlers will make life a bit easier.
  • jQuery.Sub – Allows a protected instancing of jQuery, while keeping the method access consistent for other objects that may be using your overridden methods
  • Adjacent Traversal Performance – If you use .children(), .prev(), and .next() you will see performance gains (especially if you are focusing on chrome) – speed increases from 1.4.4 are significant to say the least.

You can get the code from the official jQuery site of course.  Or you can use the following CDN links:
