2.2.0     2013-03-29
    This is the first official release supporting Ext JS 4.2. This is a quite major release with plenty of new features and refactorings.
    As of this release, we now support IE 10. We have added support for the new Neptune theme, as well as RTL support (see new samples).
    For an in-depth review of the changes in this release, please see our blog.

    We have increased our test coverage too, if you find any bugs please report them in our Assembla bug tracker.


    [FEATURES / ENHANCEMENTS]
    - IE 10 support added
    - The default row height synchronization mechanism in Ext JS was replaced with a much faster implementation, which does
      not require access to the DOM. As a result, very small row height values are now supported too.

    [API CHANGES]
    - Default value for "lockedGridDependsOnSchedule" config option is changed to true. This option was also made private,
      it is deprecated and subject for removal in any following release, please do not use it.
    - The "scheduleclick/scheduledblclick/schedulecontextmenu" events now include the resource model instance in the signature
      (for both in horizontal and vertical modes). The event object goes after it (Fixed #223).

    [BUG FIXES]

    - Fixed #667: Investigate Sch.util.Patch usage with CMD

    - Fixed #437:  Add support for improved hooks during drag drop. (See updated 'validation' example for demonstration)

2.2.0-beta-1    2013-02-08

   This is the first 2.2 beta release compatible with Ext JS 4.2 beta. A few tests are failing when running on 4.2.0.265
   but most of these tests pass (except buffering related ones) if you run against the latest Ext nightlies. You can read
   more about the details of the upgrade process on our blog: http://www.bryntum.com/blog/road-to-ext-scheduler-2-2-upgrade-guide .
   The blog post will be posted shortly. There are a few API changes that might be breaking depending on how you're using the component.

    - Basic RTL support, still in experimental stage (see new 'rtl' example)

      finalizing the operation. See the 'validation' sample for a demonstration.
    - New 'eventdrag' event fired while dragging an event

    [API CHANGES]
    - BREAKING: forceFit now defined on Panel, it was previously on the View. Compatibility patch installed.
    - BREAKING: Removed Sch.util.HeaderRenderers class (should no longer be required).
    - BREAKING: Removed Sch.view.Locking class.

     (normally a regular Ext.grid.Panel)

    - Removed 'useDragProxy' option of Sch.feature.DragDrop
    - Removed 'Sch.feature.DragZone' class

2.1.0-beta-1 2012-05-03

    This is a first beta release based on Ext JS 4.1-final. It will not work with any Ext 4.0.x version. The main feature of this release is performance,
    which is greatly improved with a new optimization mode (see "lightWeight" option)

    [FEATURES / ENHANCEMENTS]
    - added a new configuration option "lightWeight" (enabled by default). With this option, the scheduler does not create a separate
      table cell for each time interval in the bottom timeline row. Instead, it creates a single column, providing the most lightweight DOM footprint
      possible and much better performance. The downside of this optimization is that its not possible to customize every cell in the scheduler view.
      Because of that, this option is automatically disabled if a `timeCellRenderer` function is provided.

    [API CHANGES]

    [BUG FIXES]
    - Fixed #176: TreeView not refreshed after eventStore load, loadData
    - Fixed time header cell text overflow issue in IE

    - Loading XML into a Scheduler tree view should be avoided since it's not supported by Ext JS.

2.1.0-alpha-1     2012-03-09
    This is an alpha release based on Ext JS 4.1, tested only against Beta 3. It will not work with any Ext 4.0.x version.
    You can download Ext JS 4.1 B3 here: http://cdn.sencha.io/ext-4.1.0-beta-3.zip (extract it to the same folder containing Ext Scheduler 2.1):
    This release is not bug-free, and we would very much appreciate help in testing it and reporting anything you find.

    The main goal of this 2.0 release is to upgrade to Ext JS 4.1 which brings better performance. Our initial tests show a 2x speed increase for the initial rendering.
    We have also done some refactoring, and there is one breaking change: you must now use a new Sch.data.EventStore for your events.
    For guidance on using this very simple store, please see this forum thread: http://www.bryntum.com/forum/viewtopic.php?f=16&t=1737#p10365

    For more details about known issues and things relating to our products and Ext JS please see our wiki: http://www.assembla.com/spaces/bryntum/wiki
