### 2.14.3 / 2013-08-08
[full changelog](http://github.com/rspec/rspec-mocks/compare/v2.14.2...v2.14.3)
Bug Fixes:
* Fix stubbing some instance methods for classes whose hierarchy includes
a prepended Module (Bradley Schaefer)
### 2.14.2 / 2013-07-30
[full changelog](http://github.com/rspec/rspec-mocks/compare/v2.14.1...v2.14.2)
Bug Fixes:
* Fix `as_null_object` doubles so that they return `nil` from `to_ary`
(Jon Rowe).
* Fix regression in 2.14 that made `stub!` (with an implicit receiver)
return a test double rather than stub a method (Myron Marston).
### 2.14.1 / 2013-07-07
[full changelog](http://github.com/rspec/rspec-mocks/compare/v2.14.0...v2.14.1)
Bug Fixes:
* Restore `double.as_null_object` behavior from 2.13 and earlier: a
double's nullness persisted between examples in earlier examples.
While this is not an intended use case (test doubles are meant to live
for only one example), we don't want to break behavior users rely
on in a minor relase. This will be deprecated in 2.99 and removed
in 3.0. (Myron Marston)
### 2.14.0 / 2013-07-06
[full changelog](http://github.com/rspec/rspec-mocks/compare/v2.14.0.rc1...v2.14.0)
Enhancements:
* Document test spies in the readme. (Adarsh Pandit)
* Add an `array_including` matcher. (Sam Phippen)
* Add a syntax-agnostic API for mocking or stubbing a method. This is
intended for use by libraries such as rspec-rails that need to mock
or stub a method, and work regardless of the syntax the user has
configured (Paul Annesley, Myron Marston and Sam Phippen).
Bug Fixes:
* Fix `double` so that it sets up passed stubs correctly regardless of
the configured syntax (Paul Annesley).
* Allow a block implementation to be used in combination with
`and_yield`, `and_raise`, `and_return` or `and_throw`. This got fixed
in 2.13.1 but failed to get merged into master for the 2.14.0.rc1
release (Myron Marston).
* `Marshal.dump` does not unnecessarily duplicate objects when rspec-mocks has
not been fully initialized. This could cause errors when using `spork` or
similar preloading gems (Andy Lindeman).
### 2.14.0.rc1 / 2013-05-27
[full changelog](http://github.com/rspec/rspec-mocks/compare/v2.13.0...v2.14.0.rc1)
Enhancements:
* Refactor internals so that the mock proxy methods and state are held
outside of the mocked object rather than inside it. This paves the way
for future syntax enhancements and removes the need for some hacky
work arounds for `any_instance` dup'ing and `YAML` serialization,
among other things. Note that the code now relies upon `__id__`
returning a unique, consistent value for any object you want to
mock or stub (Myron Marston).
* Add support for test spies. This allows you to verify a message
was received afterwards using the `have_received` matcher.
Note that you must first stub the method or use a null double.
(Joe Ferris and Joël Quenneville)
* Make `at_least` and `at_most` style receive expectations print that they were
expecting at least or at most some number of calls, rather than just the
number of calls given in the expectation (Sam Phippen)
* Make `with` style receive expectations print the args they were expecting, and
the args that they got (Sam Phippen)
* Fix some warnings seen under ruby 2.0.0p0 (Sam Phippen).
* Add a new `:expect` syntax for message expectations
(Myron Marston and Sam Phippen).
Bug fixes
* Fix `any_instance` so that a frozen object can be `dup`'d when methods
have been stubbed on that type using `any_instance` (Jon Rowe).
* Fix `and_call_original` so that it properly raises an `ArgumentError`
when the wrong number of args are passed (Jon Rowe).
* Fix `double` on 1.9.2 so you can wrap them in an Array
using `Array(my_double)` (Jon Rowe).
* Fix `stub_const` and `hide_const` to handle constants that redefine `send`
(Sam Phippen).
* Fix `Marshal.dump` extension so that it correctly handles nil.
(Luke Imhoff, Jon Rowe)
* Fix isolation of `allow_message_expectations_on_nil` (Jon Rowe)
* Use inspect to format actual arguments on expectations in failure messages (#280, Ben Langfeld)
* Protect against improperly initialised test doubles (#293) (Joseph Shraibman and Jon Rowe)
Deprecations
* Deprecate `stub` and `mock` as aliases for `double`. `double` is the
best term for creating a test double, and it reduces confusion to
have only one term (Michi Huber).
* Deprecate `stub!` and `unstub!` in favor of `stub` and `unstub`
(Jon Rowe).
* Deprecate `at_least(0).times` and `any_number_of_times` (Michi Huber).
