+  - Support for Model and OS in image names (#121 thanks to @esttorhe)
+
+## 2.0.4
+
+  - Support loading reference images from the test bundle (#104) (Thanks to @yiding)
+  - Fix for retina tolerance comparisons (#107)
+
+## 2.0.3
+
+  - New property added `usesDrawViewHierarchyInRect` to handle cases like `UIVisualEffect` (#70), `UIAppearance` (#91) and Size Classes (#92) (#100)
+
+## 2.0.2
+
+  - Fix for retina comparisons (#96) 
+
+## 2.0.1
+
+  - Allow usage of Objective-C subspec only, for projects supporting iOS 7 (#93) (Thanks to @x2on)
+
+## 2.0.0
+
+  - Approximate comparison (#88) (Thanks to @nap-sam-dean)

+
+## 1.8.1
+
+### Fixed
+
+  - Prevent mangling of C function names when compiled with a C++ compiler. (#79)
+
+## 1.8.0
+
+### Changed
+
+  - The default directories for snapshots images are now **ReferenceImages_32** (32bit) and **ReferenceImages_64** (64bit) and the suffix depends on the architecture when the test is running. (#77) 
+  	- If a test fails for a given suffix, it will try to load and compare all other suffixes before failing.
+  - Added assertion on setRecordMode. (#76)
