I am really excited with the fact that, after many weeks of discussions, Me, Paul and all jQuery UI team decided to announce that the unreleased jQuery effects suite “Enchant”, earlier introduced as sister library to jQuery UI, is now a part of jQuery UI. With the 1.5b4 release, you’ll see a bunch of new files in the project’s folder!

The jQuery UI effects can be used standalone or together with UI and have a separate core, which extend the jQuery core to introduce easing, class transitions (morphing) and color animations. All further effects are tighly integrated into the main API and can be used as standalone ( $(..).effect() ) or directly from within jQuery methods you already know (hide()/show()).

There’s no documentation for the rich effect API at this point, but we’ll make sure it’s released before the final release of jQuery UI 1.5. In the meantime, feel free to start digging through the code - and watch more more blog posts discussing the new effects!

Overall, we have more than 15 ready-to-use effects for you to use in your projects, not only including everything you know from script.aculo.us (blind,bounce,drop,fold,slide …), but also fresh new effects (transfer, explode. clip, scale) for you to enjoy!
