script.aculo.us 1.6.4

script.aculo.us 1.6.4, which marks the inclusion of the new release candidate of Prototype 1.5, is out now.

(For those of you missing the 1.6.3 version: that version was out yesterday but had a issue with IE that is now fixed in 1.6.4)

This release comes with the brand-new Prototype V1.5.0_rc1 version, adds several new features and options to drag and drop, features a whole new (experimental) way of doing testing, and adds some other goodies here and there. Also, thanks to the contributors for identifying and squishing bugs!

So—what’s new & cool?

• Update Prototype to V1.5.0_rc1 (read more on Justin Palmer’s blog)

• Add experimental alternate syntax for unit tests (Behaviour Driven
  Development-style)

• Merge assertElementsMatch and assertElementMatches from Prototype’s
  [4986] unittest.js [Sam Stephenson]

• Add assertRespondsTo and shouldRespondTo assertions

      // object
      var testObj = {
        isNice: function() { }
      }

      // test
      assertRespondsTo('isNice', testObj);

• Make Sortable.serialize handle DOM IDs like “some_element_1” correctly, fixes #5324

• Add support for onStart, onDrag and onEnd events directly on Draggables (invoked from the Draggables.notify), fixes #4747 [thx scriptkitchen]

      new Draggable('some_id',{
        onStart:function(){ /* ... */ },
        onDrag:function(){ /* ... */ },
        onEnd:function(){ /* ... */ }
      });

• Add autoSelect option to Autocompleters to auto select an entry if only one is returned, fixes #5183 [thx cassiano dandrea]

• Added delay option to Draggables and Sortables, see test/functional/dragdrop_delay_test.html for usage, implements #3325 [thx lsimon, tomg]

• Add version and timestamp to indvidual library files for easier identification (the files are preprocessed by the Rake fresh_scriptaculous task), fixes #3015 [thx Tobie]

• Add assertIndentical and assertNotIdentical unit test assertions, which test for equality and common type, fixes #5822 [thx glazedginger]

• Add integration test for Ajax autocompleter for results with no linebreaks, #4149

• Added a custom exception to all base effects when used on non-
  existing DOM elements, added a assertRaise method to unit tests

• Add element shortcuts to Builder that can be activated by calling Builder.dump() (see the unit test), fixes #4260 [thx napalm]

      Builder.dump();
      var element = DIV({id:'ghosttrain'},[
         DIV({style:'font-size: 11px; font-weight: bold;'},[
           H1('Ghost Train'),
           "testtext", 2, 3, 4,
           UL([
             LI({onclick:'alert(\'test\')'},'click me')
           ]),
         ]),
       ]);

• Make Effect.Puff work correctly for floating elements, fixes #3777
  [thx michael hartl]

• Fix selection of correct option in SELECT element generated by
  InPlaceCollectionEditor for indexed option arrays, fixes #4789 [thx
  steve]

• Fix an issue with redrawing ghosted draggables that are inside a
  scrolled container, fixes #3860 [thx gkupps, tsukue]

• Fix autoscrolling inside scrollable containers when window is
  scrolled too, fixes #5200 [thx wseitz]

• Fix autoscrolling when dragging an element unto a scrollable
  container, fixes #5017 [thx tomg]

• Fix a condition where overriding the endeffect on Draggables without
  overriding the starteffect too leads to a Javascript error [thx
  Javier Martinez]

• Fix a possible error with the drag/drop logic (affects the solution
  to #4706)

• Fix various issues with IE detection and Opera, and setOpacity, fixes
  #3886, #5973

• Remove revert cache code obsoleted by #4706, fixes #3436 (again) [thx
  tomg]

As always, the required 1.5.0_rc1 version of Prototype is included with the download.

Big thanks to the contributors!
