 ArduinoJson: change log
 =======================
 
+v5.0.7
+------
+
+* Made library easier to use from a CMake project: simply `add_subdirectory(ArduinoJson/src)`
+* Changed `String` to be a `typedef` of `std::string` (issues #142 and #161)
+
+**BREAKING CHANGES**:
+- `JsonVariant(true).as<String>()` now returns `"true"` instead of `"1"`
+- `JsonVariant(false).as<String>()` now returns `"false"` instead of `"0"`
+
+v5.0.6
+------
+
+* Added parameter to `DynamicJsonBuffer` constructor to set initial size (issue #152)
+* Fixed warning about library category in Arduino 1.6.6 (issue #147)
+* Examples: Added a loop to wait for serial port to be ready (issue #156)
+
 v5.0.5
 ------
 
-* Add overload `JsonObjectSuscript::set(value, decimals)` (issue #143)
+* Added overload `JsonObjectSuscript::set(value, decimals)` (issue #143)
 * Use `float` instead of `double` to reduce the size of `JsonVariant` (issue #134)
 
 v5.0.4
