+## [4.2.0](https://github.com/AliSoftware/OHHTTPStubs/releases/tag/4.2.0)
+
+* Added support for stubs written in the [Mocktail](https://github.com/square/objc-mocktail) format ([@JinlianWang](https://github.com/JinlianWang), [#108](https://github.com/AliSoftware/OHHTTPStubs/pull/108))
+* The `OHHTTPStubs` spec has been splitted into **multiple subspecs**:
+  * The default subspec (used when you simply use `pod 'OHHTTPStubs'` in your `Podfile`) contains the subspecs `Core`, `NSURLSession`, `JSON` & `OHPathHelpers` (so that it matches the features that most people use).
+  * Other optional subspecs are `HTTPMessage` and `Mocktail` (which are opt-in because used by much less people). If you want to use them, you'll need to request them explicitly in your `Podfile` using `pod 'OHHTTPStubs/Mocktail` for example.
+* The iOS Unit Tests are now also run for the framework as well as for the static library, to ensure the tests pass in both contexts _(because frameworks sometimes introduce subtleties like when using `NSBundle`, so it's worth testing in that context too)_
+
 ## [4.1.0](https://github.com/AliSoftware/OHHTTPStubs/releases/tag/4.1.0)
 
 * Added support for using `OHHTTPStubs` in watchOS 2.0 targets.
