<commit_before>New features:
* Now, the Equals() method of the ICheck&lt;T&gt; instances is a real fluent check method.
* New extensible syntax for Check.That(IEnumerable xxx).Contains(...) that permits to add suffixes narrowing the conditions (e.g.: Check.That(IEnumerable xxx).Contains(...).InThatOrder()). Possible suffixes are (Only, Once or InThatOrder)
--------------
Changes:
* New error message structure that clearly states what is wrong.
* Renames the ContainsOnly() method to IsOnlyMadeOf()
* Replaces IFluentAssertion by ICheck; and IChainableFluentAssertion by ICheckLink so that it improves the IntelliSense experience.<commit_msg>Updates the Release note.<commit_after>New features:
* Now, the Equals() method of the ICheck&lt;T&gt; instances is a real fluent check method (instead of the default object.Equals() one).

* Adds check methods for IDictionary
* Adds more check methods to the IEnumerable (e.g. IsNullOrEmpty)
