The final release of jQuery UI 1.8 with 5 new plugins, 1 new effect, and hundreds of bug fixes and improvements.
We’ve worked extremely hard to make jQuery UI lighter and more modular with an even more flexible and extensible core. Now it’s even easier to build your own widgets or extend ours, whether you use the jQuery UI Widget Factory, the jQuery UI CSS Framework, or both. This release is a collective effort spanning more than 9 months with contributions from hundreds of developers, designers, testers and users. We thank you for all your help and support. And we even get personal (we’ll name names!) at the end of this post.
Note: There are significant (and in some cases breaking) changes in this release. If you currently use or develop jQuery UI plugins be sure to consult both the Changelog andUpgrade Guide for full details on these changes and their impact.
