*V1.8.1* (January 3, 2008)

* Fix Element#getStyles in IE. Closes #10563. [Tobie Langel]

* Update to Prototype 1.6.0.1 as of 8551.

* Fix a regression with autocompleters not responding correctly to cursor keys on both Safari and IE.  Closes #10107.  [thx Zman771]

*V1.8.0* (November 6, 2007)

* Update to Prototype 1.6.0 final

* Ajax.InPlaceEditor now can deal with callbacks that return an object.  Closes #10064.  [tdd]

* Fix a potential problem with the loader and Firefox 2.0 on the Mac.  Closes #9951.  [awaters]

* Add duration and distance options to Effect.Shake.  Closes #8637.  [amiel, rmm5t]

* Update code to use new Hash implemention in Prototype 1.6. Update InPlaceEditor to use new Class.create syntax.  [tdd]

*V1.8.0 preview 0* (October 12, 2007)

* Update to new Class.create syntax in Prototype 1.6; update to latest Prototype 1.6 trunk.

* Fix bottom CSS property reassignment and initialization in queues for Effect#SlideUp.  Closes #7412, #7761.

* Fix an issue with String#parseStyle that could sometimes cause errors on Safari 2.

* Refactoring to use Prototype 1.6. Remove dependency of Effect.tagifyText from builder. Use Prototype code style rules more consistently.

* Remove the deprecated Effect2 namespace.

* Update to Prototype 1.6.0_rc0.

* Some effect code refactoring to take advantage of new Prototype 1.6 features.

* Effect.ScrollTo is now no longer a core effect (returns a Effect.Tween instance now).

* Add Effect.Tween, a new core effect. This effect tweens between two values and sets a property or calls a method on an object (including DOM elements); or allows for a callback method, which will be automatically bound to the object.
  Examples:
    var whatever = { blech: 0 };
    new Effect.Tween(whatever, 5, 0, 'blech'); // sets property on the object
    new Effect.Tween('foo', 10, 20, 'innerHTML'); // sets property on the 'foo' DOM element
    new Effect.Tween('foo', 10, 20, 'update');    // method call on 'foo' DOM element
    new Effect.Tween('foo', 50, 0, { duration: 2.0 }, function(p){
      this.setStyle({border:p.toFixed(3)+'px solid red'});
    });
    new Effect.Tween(null, 0, 100, function(p){ scrollTo(0,p) }); // scrolls the window

* Revert the workaround for the Firefox issue that makes autocompleter input field values be remembered correctly when the back button is hit to return to a page that contains autocompleted values, as this can cause "Are you sure you want to navigate away?" popups.  Closes #8411.  [okada]

* Improve the way deactivating the active droppable is handled.  Closes #9072.  [Karsten Sperling]

* Next version will be 1.8.0. Update to Prototype 1.6.0_pre1.

* Make draggable initialization faster.  Closes #8697.  [ssinghi]

* Make BDD-style testing compatible with IE6 and IE7.  Closes #8972.  [steveluscher]

* Add BDD methods to booleans.  Closes #9147.  [steveluscher]

* Add support for full CSS inheritance in Effect.Morph.  Closes #9054.  [Tobie]
  IMPORTANT: Note that this could potentially change the outcome of classname-based morphs, so be sure to check your morph effects if you use this feature. 
  For this feature, the new method Element#getStyles is introduced, which returns an objects which properties correspond to the CSS properties found in Element.CSS_PROPERTIES. Note that this method doesn't work seemlessly across browsers for certain non-measurable CSS properties, such as float.  

* Add the externalControlOnly option to the in-place editors to allow for external controls to exclusively trigger the in-place editing.  Closes #9024.  [tdd]

* Complete rewrite of Ajax.InPlaceEditor and Ajax.InPlaceCollectionEditor.  [tdd]
  THIS UPDATE MIGHT AFFECT BACKWARDS COMPATIBILITY.
  Be sure to properly test, especially if you're using multi-line editing and/or monkeypatching.
  Read more about all the added goodness in this article:
  http://mir.aculo.us/2007/7/17/in-place-editing-the-summer-2007-rewrite

* Update to Prototype 1.5.2_rc0 r7076:
  - Works around bugs in Safari 1 and Safari 2 Regexp engines that could cause crashes
  - Fixes a rendering issue with opacity-based effects and floating elements on Safari

* Mild refactoring of sound.js to take advantage of new Prototype features.

* Add highlight element method as a shortcut to Effect.Highlight.
    Example:
      $('message').highlight({startcolor:'#ff0000'}).update('KTHXBYE');

* Improve performance of String.prototype.parseStyle by caching the dummy element used.

* Add combined effects as element methods.
    Examples:
      $('message').appear().update('Oh noes!');
      $('login').shake({ duration: 2 });

* Add Effect.Transitions.spring, which simulates a spring which oscillates while coming to rest. This transition is specifically targeted towards use with Effect.Move, for example as a reverteffect when using Draggables, as it will have return values >1 and cause temporary "overshooting" of the effect.  Closes #8474.  [edg2s]

* Fix effects initialization if no options are given.  Fixes #7809.  [thx Kroc Camen]

* Fix incorrect placement on drop for absolute ghosting elements. Update to Prototype 1.5.2_rc0 r6955 (required for #8581). Closes #8581.  [tdd]

* Make sure the autocompletion happens on the token where the cursor is, not the last token when using tokenized autocompleting text fields.  Closes #8588.  [tdd]

* Fix that non-Mozilla browsers would display messages with the autocompleter back-button fix introduced in 1.7.1 beta 2. Fixes #7752, #8411. [josh, stetz] 

*V1.7.1 beta 3* (May 19, 2007)

* Update to Prototype 1.5.1 final

* New elements and handles options for Sortable.create which take arrays of elements or element ids. These overrule the normal handle and elements finding options on initialization of the sortable, and can yield huge performance increases in situations where these elements or ids are known at call time. [Thomas Fuchs]

* Major performance improvement of Sortable.create when using the handle option. [Tobie Langel]

* Fix Builder.node double quote escaping in attributes, fixes #8125. [Aa!]

*V1.7.1 beta 2* (April 28, 2007)

* Update to Prototype 1.5.1_rc4
  - Various optimizations and fixes
  - http://dev.rubyonrails.org/browser/spinoffs/prototype/trunk/CHANGELOG?rev=6604

* Fix autocompleter indicator not appearing when calling activate() directly. Don't show indicator for local autocompleting. Fixes #7770. [pyro8019]

* Don't clear out autocompleting fields in Mozilla-based browsers when navigating back to a page with the Back button, fixes #7752. [seanc]

*V1.7.1 beta 1* (March 12, 2007)

* Update to Prototype 1.5.1 r6386
  - Fixes SlideUp/SlideDown on IE
  - Fixes an opacity problem with IE
  - Performance optimizations
  - See http://dev.rubyonrails.org/browser/spinoffs/prototype/trunk/CHANGELOG?rev=6381 for more information
    
* Make builder unit tests work on IE

* Fix id assignment for sounds on Firefox/Windows, fixes #7709 [Robert Wallis]

* Add Sound.enable() and Sound.disable() to globally turn off Sound.play()

* Added Sound.play(url,options) in new sound.js file. scriptaculous.js automatically includes this file.
  Based on code by Jules Gravinese, used with permission.
  
  The sound player uses native sound support on IE, and falls back to using <embed> on other browsers,
  which means it uses QuickTime for most cases. The recommended format to use is MP3.
  
    Examples:
      Sound.play('blah.mp3');   
      // --> plays sound immediately in 'global' track
      Sound.play('blah.mp3',{replace:true});  
      // --> stop playing all sounds in 'global' track, and play new sound
      Sound.play('blah.mp3',{track:'mytrack'});
      // --> places the sound in the 'mytrack' track
      Sound.play('blah.mp3',{track:'mytrack',replace:true});
      // --> stop playing all sounds in 'mytrack' track, and play new sound
      
  The sound effect used in the functional test is "Sword being drawn" by James Greever, released as freeware.

* Various effects engine optimizations [Tobie Langel, Thomas Fuchs]

* Make Ajax.InPlaceEditor more customizable: [thx godlie]

    * Fixes issue with Safari when using Prototype's Ajax helpers with HTTP authorization

* Add hash and CSS className support to Effect.Morph, fixes #6674 [Tobie]
    Examples:
      $(element).morph('myClass')
      // will morph to all the properties specified
      // in .className (in your external stylesheet).
      // All properties which cannot be morphed (such as font-style)
      // will be applied AfterFinish
      $(element).morph('font-size: 10px')  // or
      $(element).morph({fontSize: '10px'}) // will morph the font-size to 10px
      
*V1.7.0 beta 1* (November 21, 2006)

* Add Element.morph() and Element.Methods.morph() as a shortcut to Effect.Morph
    Example:
      // basic Effect.Morph
      $('error_message').morph('color:#f00;font-size:17px');
      // fade out after a while
      $('error_message').show().morph('font-size:17px').morph('opacity:0',{delay:4});

* Update to Prototype 1.5.0_rc2 revision [5580]

        { 'div.morphing': 'font-size:20px;padding-left:40em' },
        { 'blah'        : 'width:480px;border-width:10px;border-right-width:20px;margin:200px;margin-bottom:-20px;font-size:30px' }
      ],{ duration: 0.5 });
      // play transformation (can be called more than once)
      transformation.play();

* Add Effect.Morph core effect that morphs to a given CSS style rule. Effect.Morph does take orginal styles given by CSS style rules or the style attribute into consideration when calculating the transforms. It works with all length and color based CSS properties, including margins, paddings, borders, opacity and text/background colors.
    Example:
      new Effect.Morph('mydiv',{
        style: 'font-size:3em;color:#f00;border-width:2em',
        duration: 2.0
      });

* Update to Prototype 1.4.0_pre4

*V1.5.0_pre4*

* Added a queue option to effects for easy stacking and simple timeline building. Valid values are "front", "end" and "parallel" (default), see for test/functional/effects_queue_test.html for usage

* Added a setup function to the core effects that gets called by Effect.Base when first entering into running state, which allows them to query the current state of an element or other page properties when queuing and/or delays are used

* Added a state instance variable to Effect.Base that indicates whether a effect that uses the queue is idle, running or finished

* Fixed a flicker with Effect.Puff

* General code cleaning to get rid of (legitimate) Mozilla strict javascript warnings

* Changes to assertVisible in unittest.js

* Made tagifyText work with IE. defaults to a style of "position: relative; zoom:1;" for the created SPAN wrappers. It also replaces spaces with non-breakable spaces. These sit-ups are required to work around problems with rendering elements with the proprietary IE "layout" and non-quirksmode documents.

* Add a break to scriptaculous.js when the includes are done [thx to Danilo Celic]

* Fixed a problem with the Autocompleter when hitting ESC would select the entry in IE and redisplay the entries box in Safari

* Changed version number in scriptaculous.js to 1.5_pre3

* Moved setting focus in Autocompleter to updateElement function to make it overridable [Brian Palmer]

* Added special handling for style attributes to Builder [Michael Schuerig]

* Changed opacity=1.0 check back to be inline with its original (pre 1.5) implementation to prevent flickering in Firefox < 1.1 on opacity-based effects (this also fixes flickering with drag-and-drop, sortable lists and autocompleting text fields). Note that this potentially breaks correct colors in some situations. [thx to David Zülke]

* Automatically deactivate browser built-in autocompletion on autocompleting textfields, fixes part of Rails #1824.

* Fixed a problem with Ajax.InPlaceEditor causing a JavaScript exception on Safari [thx to Patrick Lenz]

  <script src="path/to/prototype.js" type="text/javascript"></script>
  <script src="path/to/scriptaculous.js" type="text/javascript"></script>
  
  in the HEAD section of an HTML file is now all that's needed to include all of the script.aculo.us libraries, 
  given that they all can be accessed by the same path as scriptaculous.js is.

* Fixed possible problem with greedy Droppables when using the dropOnEmpty option on Sortable.create

* Added new CSS/background color features to Ajax.InPlaceEditor [Jon Tirsen]

* Added unit test for Autocompleter, first Version

* Added Event.simulateKey/s to unittest.js. Note that due to a bug in Firefox this will only work with Firefox up to v1.0.4 (see https://bugzilla.mozilla.org/show_bug.cgi?id=289940)

* Fixed a condition where standard a href=xxx links wouldn't work in autocomplete results. These do now, the onclick event is not cancelled. [thx to Jasper Slits]

* Fix showing ghosting marker only on ghosting Sortables

* Some more Builder stuff, expanded builder unit tests

* Moved stuff that didn't belong into specific libs into util.js; util.js is now required for all script.aculo.us libs

* Corrected weirdness in unittest.js

* Added dropOnEmpty option to Sortables to allow dropping on empty lists (see test/functional/sortable3_test.html)

* Renamed the clone option on Draggables to "ghosting".

* Added experimental "clone" option to Draggable to so that a "clone" stays in place while dragging a translucent version of the draggable element. Currently, this requires relatively positioned elements, and doesn't work with sortable lists (but should after some tweaking). See dragdrop_function_4.html test file for details.

* Added Element.getStyle to find computed CSS styles of an element. Note: doesn't work in all cases in Safari, see my bug report at http://bugzilla.opendarwin.org/show_bug.cgi?id=4125
