September 6th, 2006 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?

  • 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]

      var element = DIV({id:'ghosttrain'},[
         DIV({style:'font-size: 11px; font-weight: bold;'},[
           H1('Ghost Train'),
           "testtext", 2, 3, 4,
             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
  • 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

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

Big thanks to the contributors!
