+------
+
+* Fixed compilation error with Intel Galileo (issue #299)
+
+v5.5.0
+------
+
+* Added `JsonVariant::success()` (issue #279)
+* Renamed `JsonVariant::invalid<T>()` to `JsonVariant::defaultValue<T>()`
+
+v5.4.0
+------
+
+* Changed `::String` to `ArduinoJson::String` (issue #275)
+* Changed `::Print` to `ArduinoJson::Print` too

+* Added `JsonVariant JsonBuffer::parse()` (issue #265)
+* Fixed `unsigned long` printed as `signed long` (issue #170)
+
+v5.2.0

+* Added example `JsonHttpClient` (issue #256)
+* Added `JsonArray::copyTo()` and `JsonArray::copyFrom()` (issue #254)
+* Added `RawJson()` to insert pregenerated JSON portions (issue #259)
+
+v5.1.1
+------

+
+v5.1.0
+------
+
+* Added support of `long long` (issue #171)
+* Moved all build settings to `ArduinoJson/Configuration.hpp`

+v5.0.8
+------
+
+* Made the library compatible with [PlatformIO](http://platformio.org/) (issue #181)
+* Fixed `JsonVariant::is<bool>()` that was incorrectly returning false (issue #214)
+
+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
+------
+
+* Added overload `JsonObjectSuscript::set(value, decimals)` (issue #143)
+* Use `float` instead of `double` to reduce the size of `JsonVariant` (issue #134)

+v5.0.4
+------
+
+* Fixed ambiguous overload with `JsonArraySubscript` and `JsonObjectSubscript` (issue #122)
+
+v5.0.3
+------
+
+* Fixed `printTo(String)` which wrote numbers instead of strings (issue #120)
+* Fixed return type of `JsonArray::is<T>()` and some others (issue #121)
+
+v5.0.2
+------
+
+* Fixed segmentation fault in `parseObject(String)` and `parseArray(String)`, when the 
+  `StaticJsonBuffer` is too small to hold a copy of the string
+* Fixed Clang warning "register specifier is deprecated" (issue #102)
+* Fixed GCC warning "declaration shadows a member" (issue #103)
+* Fixed memory alignment, which made ESP8266 crash (issue #104)
+* Fixed compilation on Visual Studio 2010 and 2012 (issue #107)
+
 v5.0.1
 ------
