 ArduinoJson: change log
 =======================
 
+v5.7.0
+------
+
+* Templatized all functions using `String` or `std::string`
+* Removed `ArduinoJson::String`
+* Removed `JsonVariant::defaultValue<T>()`
+* Removed non-template `JsonObject::get()` and `JsonArray.get()`
+* Fixed support for `StringSumHelper` (issue #184)
+* Replaced `ARDUINOJSON_USE_ARDUINO_STRING` by `ARDUINOJSON_ENABLE_STD_STRING` and `ARDUINOJSON_ENABLE_ARDUINO_STRING` (issue #378)
+* Added example `StringExample.ino` to show where `String` can be used
+* Increased default nesting limit to 50 when compiled for a computer (issue #349)
+
+**BREAKING CHANGES**:
+
+The non-template functions `JsonObject::get()` and `JsonArray.get()` have been removed. This means that you need to explicitely tell the type you expect in return.
+
+Old code:
+
+```c++
+#define ARDUINOJSON_USE_ARDUINO_STRING 0
+JsonVariant value1 = myObject.get("myKey");
+JsonVariant value2 = myArray.get(0);
+```
+
+New code:
+
+```c++
+#define ARDUINOJSON_ENABLE_ARDUINO_STRING 0
+#define ARDUINOJSON_ENABLE_STD_STRING 1
+JsonVariant value1 = myObject.get<JsonVariant>("myKey");
+JsonVariant value2 = myArray.get<JsonVariant>(0);
+```
+
+
+v5.6.7
+------
+
+* Fixed `array[idx].as<JsonVariant>()` and `object[key].as<JsonVariant>()`
+* Fixed return value of `JsonObject::set()` (issue #350)
+* Fixed undefined behavior in `Prettyfier` and `Print` (issue #354)
+* Fixed parser that incorrectly rejected floats containing a `+` (issue #349)
+
+v5.6.6
+------
+
+* Fixed `-Wparentheses` warning introduced in v5.6.5 (PR #335 by @nuket)
+* Added `.mbedignore` for ARM mbdeb (PR #334 by @nuket)
+* Fixed  `JsonVariant::success()` which didn't propagate `JsonArray::success()` nor `JsonObject::success()` (issue #342).
+
+v5.6.5
+------
+
+* `as<char*>()` now returns `true` when input is `null` (issue #330)
+
+v5.6.4
+------
+
+* Fixed error in float serialization (issue #324)
+
+v5.6.3
+------
+
+* Improved speed of float serialization (about twice faster)
+* Added `as<JsonArray>()` as a synonym for `as<JsonArray&>()`... (issue #291)
+* Fixed `call of overloaded isinf(double&) is ambiguous` (issue #284)
+
+v5.6.2
+------
+
+* Fixed build when another lib does `#undef isnan` (issue #284)
+
+v5.6.1
+------
+
+* Added missing `#pragma once` (issue #310)
+
+v5.6.0
+------
+
+* ArduinoJson is now a header-only library (issue #199)
+
+v5.5.1
+------
+
+* 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
+
+v5.3.0
+------
+
+* Added custom implementation of `ftoa` (issues #266, #267, #269 and #270)
+* Added `JsonVariant JsonBuffer::parse()` (issue #265)
+* Fixed `unsigned long` printed as `signed long` (issue #170)
+
+v5.2.0
+------
+
+* Added `JsonVariant::as<char*>()` as a synonym for `JsonVariant::as<const char*>()` (issue #257)
+* 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
+------
+
+* 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)
+

+> I tried aJson json-arduino before trying your library. I always ran into memory problem after a while.
 > I have no such problem so far with your library. It is working perfectly with my web services.
 
-From Arduino's Forum user `gbathree`:
-> Thanks so much - this is an awesome library!  If you want to see what we're doing with it - the project is located at www.photosynq.org.
-
 From StackOverflow user `thegreendroid`:
 > It has a really elegant, simple API and it works like a charm on embedded and Windows/Linux platforms. We recently started using this on an embedded project and I can vouch for its quality.
 
 From GitHub user `zacsketches`:
-
 > Thanks for a great library!!!
 > I've been watching you consistently develop this library over the past six months, and I used it today for a publish and subscribe architecture designed to help hobbyists move into more advanced robotics. Your library allowed me to implement remote subscription in order to facilitate multi-processor robots.
 > ArduinoJson saved me a week's worth of time!!
 
+[From Reddit user `erm_what_`](https://www.reddit.com/r/arduino/comments/3jj6ep/announcing_arduinojson_50/cusjk8c):
+> This is a great library and I wouldn't be able to do the project I'm doing without it. I completely recommend it.
+
+[From Reddit user `makerhacks`](https://www.reddit.com/r/arduino/comments/3jj6ep/announcing_arduinojson_50/cusqg7b):
+> I am just starting an ESP8266 clock project and now I can output JSON from my server script and interpret it painlessly.
+
+[From Twitter user `@hemalchevli`](https://twitter.com/hemalchevli/status/715788439397011456):
+> ArduinoJson library should be used as a benchmark/reference for making libraries. Truly elegant.
