 ArduinoJson: change log
 =======================
 
+v5.8.2
+------
+
+* Fixed parsing of comments (issue #421)
+* Fixed ignored `Stream` timeout (issue #422)
+* Made sure we don't read more that necessary (issue #422)
+* Fixed error when the key of a `JsonObject` is a `char[]` (issue #423)
+* Reduced code size when using `const` references
+* Fixed error with string of type `unsigned char*` (issue #428)
+* Added `deprecated` attribute on `asArray()`, `asObject()` and `asString()` (issue #420)
+
+v5.8.1
+------
+
+* Fixed error when assigning a `volatile int` to a `JsonVariant` (issue #415)
+* Fixed errors with Variable Length Arrays (issue #416)
+* Fixed error when both `ARDUINOJSON_ENABLE_STD_STREAM` and `ARDUINOJSON_ENABLE_ARDUINO_STREAM` are set to `1`
+* Fixed error "Stream does not name a type" (issue #412)
+
+v5.8.0
+------
+
+* Added operator `==` to compare `JsonVariant` and strings (issue #402)
+* Added support for `Stream` (issue #300)
+* Reduced memory consumption by not duplicating spaces and comments
+
+**BREAKING CHANGES**:
+
+`JsonBuffer::parseObject()` and  `JsonBuffer::parseArray()` have been pulled down to the derived classes `DynamicJsonBuffer` and `StaticJsonBufferBase`.
+
+This means that if you have code like:
+
+```c++
+void myFunction(JsonBuffer& jsonBuffer);
+```
+
+you need to replace it with one of the following:
+
+```c++
+void myFunction(DynamicJsonBuffer& jsonBuffer);
+void myFunction(StaticJsonBufferBase& jsonBuffer);
+template<typename TJsonBuffer> void myFunction(TJsonBuffer& jsonBuffer);
+```
+
+v5.7.3
+------
+
+* Added an `printTo(char[N])` and `prettyPrintTo(char[N])` (issue #292)
+* Added ability to set a nested value like this: `root["A"]["B"] = "C"` (issue #352)
+* Renamed `*.ipp` to `*Impl.hpp` because they were ignored by Arduino IDE (issue #396)
+
+v5.7.2
+------
+
+* Made PROGMEM available on more platforms (issue #381)
+* Fixed PROGMEM causing an exception on ESP8266 (issue #383)
+
+v5.7.1
+------
+
+* Added support for PROGMEM (issue #76)
+* Fixed compilation error when index is not an `int` (issue #381)
+
+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)

+* 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)

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

+* 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 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

+It's designed to have the most intuitive API, the smallest footprint and is able to work without any allocation on the heap (no malloc).
 
 It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
+For instance, it supports Aduino's `String` and `Stream`, but also `std::string`, `std::istream` and `std::ostream`.

 #### Decoding / Parsing
-   
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    StaticJsonBuffer<200> jsonBuffer;
+```c++
+char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    JsonObject& root = jsonBuffer.parseObject(json);
+StaticJsonBuffer<200> jsonBuffer;
 
-    const char* sensor = root["sensor"];
-    long time          = root["time"];
-    double latitude    = root["data"][0];
-    double longitude   = root["data"][1];
+JsonObject& root = jsonBuffer.parseObject(json);
+
+const char* sensor = root["sensor"];
+long time          = root["time"];
+double latitude    = root["data"][0];
+double longitude   = root["data"][1];
+```

-    StaticJsonBuffer<200> jsonBuffer;
 
-    JsonObject& root = jsonBuffer.createObject();
-    root["sensor"] = "gps";
-    root["time"] = 1351824120;
+```c++
+StaticJsonBuffer<200> jsonBuffer;
 
-    JsonArray& data = root.createNestedArray("data");
-    data.add(48.756080, 6);  // 6 is the number of decimals to print
-    data.add(2.302038, 6);   // if not specified, 2 digits are printed
+JsonObject& root = jsonBuffer.createObject();

 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):
