- Added methods for asserting that a collection of types matching a predicate have specific methods that are virtual or marked with a specific attribute.
     - Added methods for asserting XElements and Xattributes
     - Added support for recursively comparing the properties of nested (collection of objects ). By default it will compare all properties of the expected object graph, unless SharedProperties is used.
     - Added a fallback mechanism so that if FA cannot find any of the supported frameworks, it will fall back to using a custom AssertFailedException exception class rather than crashing.
     - Added support for ComparisonMode.StartWith and ComparisonMode.StartWithEquivalent when asserting the message of an exception.
     - For assertions that verify against a Type, the failure message will use the AssemblyQualifiedName rather than just the name of the type.
     - Fixed a bug so that collection.Should().OnlyContain(lamba) now throws if the collection is empty. See this discussion for more details.
     - Minor fix that ignores trailing blank characters when looking for the 'because' text in the reason of an assertion.
     - Added better and deeper detection of cyclic references when recursively comparing properties or generating a string representation of a complex object graph.
     - For long strings, the error message for string.Should().StartWith() places the actual and expected strings on seperate lines. This makes it easier to find the differences.
