-Arduino JSON: change log
-========================
+ArduinoJson: change log
+=======================
+
+v5.1.1
+------
+
+* Removed `String` duplication when one replaces a value in a `JsonObject` (PR #232 by @ulion)
+
+v5.1.0
+------
+
+* Added support of `long long` (issue #171)
+* Moved all build settings to `ArduinoJson/Configuration.hpp`
+
+**BREAKING CHANGE**:
+If you defined `ARDUINOJSON_ENABLE_STD_STREAM`, you now need to define it to `1`.
+
+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
+------
+
+* Fixed compilation with Arduino 1.0.6 (issue #99)
+
+v5.0.0
+------
+
+* Added support of `String` class (issues #55, #56, #70, #77)
+* Added `JsonBuffer::strdup()` to make a copy of a string (issues #10, #57)
+* Implicitly call `strdup()` for `String` but not for `char*` (issues #84, #87)
+* Added support of non standard JSON input (issue #44)
+* Added support of comments in JSON input (issue #88)
+* Added implicit cast between numerical types (issues #64, #69, #93)
+* Added ability to read number values as string (issue #90)
+* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators (issue #66)
+* Switched to new the library layout (requires Arduino 1.0.6 or above)
+
+**BREAKING CHANGES**:
+- `JsonObject::add()` was renamed to `set()`
+- `JsonArray::at()` and `JsonObject::at()` were renamed to `get()`
+- Number of digits of floating point value are now set with `double_with_n_digits()`
+
+**Personal note about the `String` class**:
+Support of the `String` class has been added to the library because many people use it in their programs.
+However, you should not see this as an invitation to use the `String` class.
+The `String` class is **bad** because it uses dynamic memory allocation.
+Compared to static allocation, it compiles to a bigger, slower program, and is less predictable.
+You certainly don't want that in an embedded environment!
+
+v4.6
+----
+
+* Fixed segmentation fault in `DynamicJsonBuffer` when memory allocation fails (issue #92)
+
+v4.5
+----
+
+* Fixed buffer overflow when input contains a backslash followed by a terminator (issue #81)
+
+**Upgrading is recommended** since previous versions contain a potential security risk.
+
+Special thanks to [Giancarlo Canales Barreto](https://github.com/gcanalesb) for finding this nasty bug.
+
+v4.4
+----
+
+* Added `JsonArray::measureLength()` and `JsonObject::measureLength()` (issue #75)
