Changes in version 2.0

New

• Based on xUnit.net 2.0 and supporting all new xUnit.net 2.0 features.
• Official support for Mono.*
• Support for all platforms supported by xUnit.net 2.0 (Desktop .NET 4.5+, Windows 8.1+ (Universal)*, Windows Phone 8+ (Silverlight)*, Windows Phone 8.1+ (Universal)*, MonoTouch*, MonoAndroid*, Xamarin.iOS*).
• x(), an alternative to f() and _().*

Changed

• Object disposal and Teardown are no longer represented as a separate test unless an exception is thrown during their execution. This aligns with the behaviour of most xUnit.net 2.0 runners which show an extra failed test when test clean up fails.
• The Before() and After() methods of a BeforeAfterTestAttribute are now called before and after each scenario is run. In xBehave.net 1.x, these methods were called before and after each step within a scenario was run.

Removed

• Given(), When(), Then(), And() and But(). Use f(), _() or x()* instead.
• Timeouts have been removed under the same rationale used for xUnit.net 2.0.
• Isolated steps have been removed as this is a rarely (if ever) used feature that adds considerable implementation overhead.
• Object disposal without passing a context object to Using() (already deprecated in 1.x).
• An undocumented feature which allows global continuation of step execution when certain types of step fail.
• An undocumented feature which allows omission of arguments from scenario names in test output.

* Work in progress - not yet provided in the current pre-release package.
