    [KNOWN ISSUES]

    [FEATURES / ENHANCEMENTS]
    - New 'instantUpdate' config on the Gnt.widget.DurationEditor class (defaults to true). When the spinners are activated, the underlying record is updated instantly.

    "OverrideEndDate". This fixes a lot of issues with calendars CRUD. Calendar still can be loaded with the data in old format,
    but you should not rely on this anymore.
    - BREAKING: The internals of advanced calendar widget were significantly refactored. This feature was not documented so hopefully this change
    will not affect anyone - the public API remains the same

    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.
