-Old generator API:
+> ### BREAKING CHANGES
+> 
+> #### NaN and Infinity
+> 
+> The JSON specification allows neither NaN not Infinity, but previous
+> versions of ArduinoJson supported it. Now, ArduinoJson behaves like most
+> other libraries: a NaN or and Infinity in the `JsonDocument`, becomes
+> a `null` in the output JSON. Also, `deserializeJson()` returns
+> `InvalidInput` if the JSON document contains NaN or Infinity.
+> 
+> This version still supports NaN and Infinity in JSON documents, but
+> it's disabled by default to be compatible with other JSON parsers.
+> If you need the old behavior back, define `ARDUINOJSON_ENABLE_NAN` and
+> `ARDUINOJSON_ENABLE_INFINITY` to `1`;:
+> 
+> ```c++
+> #define ARDUINOJSON_ENABLE_NAN 1
+> #define ARDUINOJSON_ENABLE_INFINITY 1
+> #include <ArduinoJson.h>
+> ```
+> 
+> #### The "or" operator
+> 
+> This version slightly changes the behavior of the | operator when the 
+> variant contains a float and the user requests an integer.
+>
+> Older versions returned the floating point value truncated.
+> Now, it returns the default value.
+> 
+> ```c++
+> // suppose variant contains 1.2
+> int value = variant | 3;
+> 
+> // old behavior:
+> value == 1
+> 
+> // new behavior
+> value == 3
+> ```
+> 
+> If you need the old behavior, you must add `if (variant.is<float>())`.

-    root.add("data", array);
+v6.10.1 (2019-04-23)
+-------
 
-New generator API:
+* Fixed error "attributes are not allowed on a function-definition"

+-------
 
-v3.0
-----
+* Fixed an integer overflow in the JSON deserializer
+* Added overflow handling in `JsonVariant::as<T>()` and `JsonVariant::is<T>()`.
+   - `as<T>()` returns `0` if the integer `T` overflows
+   - `is<T>()` returns `false` if the integer `T` overflows
+* Added `BasicJsonDocument` to support custom allocator (issue #876)
+* Added `JsonDocument::containsKey()` (issue #938)
+* Added `JsonVariant::containsKey()`
 
-* New parser API, see bellow
-* Renamed `JsonHashTable` into `JsonObject`
-* Added iterators for `JsonArray` and `JsonObject` (issue #4)
+v6.9.1 (2019-03-01)
+------
 
-Old parser API:
+* Fixed warning "unused variable" with GCC 4.4 (issue #912)
+* Fixed warning "cast  increases required alignment" (issue #914)
+* Fixed warning "conversion may alter value" (issue #914)
+* Fixed naming conflict with "CAPACITY" (issue #839)
+* Muted warning "will change in GCC 7.1" (issue #914)
+* Added a clear error message for `StaticJsonBuffer` and `DynamicJsonBuffer`
+* Marked ArduinoJson.h  as a "system header"
 
-    JsonHashTable root = parser.parseHashTable(json);
+v6.9.0 (2019-02-26)
+------
 
-	char*  sensor    = root.getString("sensor");
-	long   time      = root.getLong("time");
-	double latitude  = root.getArray("data").getDouble(0);
-    double longitude = root.getArray("data").getDouble(1);
+* Decode escaped Unicode characters like \u00DE (issue #304, PR #791)
+  Many thanks to Daniel Schulte (aka @trilader) who implemented this feature.

+* Converted `JsonArray::copyFrom()/copyTo()` to free functions `copyArray()`
+* Renamed `JsonArray::copyFrom()` and `JsonObject::copyFrom()` to `set()`
+* Renamed `JsonArray::get()` to `getElement()`
+* Renamed `JsonArray::add()` (without arg) to `addElement()`

+* Added `JsonDocument::size()`
+* Added `JsonDocument::remove()`
+* Added `JsonVariant::clear()`
+* Added `JsonVariant::remove()`
 
-New parser API:
+v6.8.0-beta (2019-01-30)
+-----------
 
-	JsonObject root = parser.parse(json);
+* Import functions in the ArduinoJson namespace to get clearer errors
+* Improved syntax highlighting in Arduino IDE
+* Removed default capacity of `DynamicJsonDocument`
+* `JsonArray::copyFrom()` accepts `JsonArrayConst`
+* `JsonVariant::set()` accepts `JsonArrayConst` and `JsonObjectConst`
+* `JsonDocument` was missing in the ArduinoJson namespace
+* Added `memoryUsage()` to `JsonArray`, `JsonObject`, and `JsonVariant`
+* Added `nesting()` to `JsonArray`, `JsonDocument`, `JsonObject`, and `JsonVariant`
+* Replaced `JsonDocument::nestingLimit` with an additional parameter
+  to `deserializeJson()` and `deserializeMsgPack()`
+* Fixed uninitialized variant in `JsonDocument`
+* Fixed `StaticJsonDocument` copy constructor and copy assignment
+* The copy constructor of `DynamicJsonDocument` chooses the capacity according to the memory usage of the source, not from the capacity of the source.
+* Added the ability to create/assign a `StaticJsonDocument`/`DynamicJsonDocument` from a `JsonArray`/`JsonObject`/`JsonVariant`
+* Added `JsonDocument::isNull()`
+* Added `JsonDocument::operator[]`

+* `JsonVariant` automatically promotes to `JsonObject` or `JsonArray` on write.
+  Calling `JsonVariant::to<T>()` is not required anymore.
+* `JsonDocument` now support the same operations as `JsonVariant`.
+  Calling `JsonDocument::as<T>()` is not required anymore.
+* Fixed example `JsonHttpClient.ino`
+* User can now use a `JsonString` as a key or a value
 
-	char*  sensor    = root["sensor"];
-    long   time      = root["time"];
-    double latitude  = root["data"][0];
-    double longitude = root["data"][1];
+> ### BREAKING CHANGES
+> 
+> #### `DynamicJsonDocument`'s constructor
+> 
+> The parameter to the constructor of `DynamicJsonDocument` is now mandatory
+>
+> Old code:
+>
+> ```c++
+> DynamicJsonDocument doc;
+> ```
+>
+> New code:
+>
+> ```c++
+> DynamicJsonDocument doc(1024);
+> ```
+> 
+> #### Nesting limit
+> 
+> `JsonDocument::nestingLimit` was replaced with a new parameter to `deserializeJson()` and `deserializeMsgPack()`.
+> 
+> Old code:
+> 
+> ```c++
+> doc.nestingLimit = 15;
+> deserializeJson(doc, input);
+> ```
+> 
+> New code: 
+> 
+> ```c++
+> deserializeJson(doc, input, DeserializationOption::NestingLimit(15));
+> ```

-v1.2
-----
+v6.4.0-beta (2018-09-11)
+-----------
 
-* Fixed error in JSON parser example (issue #1)
+* Copy `JsonArray` and `JsonObject`, instead of storing pointers (issue #780)
+* Added `JsonVariant::to<JsonArray>()` and `JsonVariant::to<JsonObject>()`
 
-v1.1
-----
+v6.3.0-beta (2018-08-31)
+-----------
 
-* Example: changed `char* json` into `char[] json` so that the bytes are not write protected
-* Fixed parsing bug when the JSON contains multi-dimensional arrays
+* Implemented reference semantics for `JsonVariant`
+* Replaced `JsonPair`'s `key` and `value` with `key()` and `value()`

-v1.0 
-----
+> ### BREAKING CHANGES
+>
+> #### JsonVariant
+> 
+> `JsonVariant` now has a semantic similar to `JsonObject` and `JsonArray`.
+> It's a reference to a value stored in the `JsonDocument`.
+> As a consequence, a `JsonVariant` cannot be used as a standalone variable anymore.
+>
+> Old code:
+>
+> ```c++
+> JsonVariant myValue = 42;
+> ```
+>
+> New code:
+>
+> ```c++
+> DynamicJsonDocument doc;
+> JsonVariant myValue = doc.to<JsonVariant>();
+> myValue.set(42);
+> ```
+>
+> #### JsonPair
+>
+> Old code:
+>
+> ```c++
+> for(JsonPair p : myObject) {
+>   Serial.println(p.key);
+>   Serial.println(p.value.as<int>());
+> }
+> ```
+>
+> New code:
+>
+> ```c++
+> for(JsonPair p : myObject) {
+>   Serial.println(p.key());
+>   Serial.println(p.value().as<int>());
+> }
+> ```
+>
+> CAUTION: the key is now read only!

+>
+> Old code:
+>
+> ```c++
+> object["values"] = RawJson("[1,2,3,4]");

+>
+> ```c++
+> JsonObject& obj = doc.to<JsonObject>();
+> JsonArray& arr = obj.createNestedArray("key");
+> if (!arr.success()) {
+>   Serial.println("Not enough memory");

+
+> ### New rules for string duplication
+>
+> | type                       | duplication |
+> |:---------------------------|:------------|
+> | const char*                | no          |
+> | char*                      | ~~no~~ yes  |
+> | String                     | yes         |
+> | std::string                | yes         |

+>
+> These new rules make `JsonBuffer::strdup()` useless.

+>
+> If you have a block like this:
+>
+> ```c++
+> const char* ssid = root["ssid"];
+> if (!ssid)
+>   ssid = "default ssid";
+> ```
+>
+> You can simplify like that:
+>
+> ```c++
+> const char* ssid = root["ssid"] | "default ssid";
+> ```

+* Reduced memory consumption by not duplicating spaces and comments
+
+> ### BREAKING CHANGES :warning:
+>
+> `JsonBuffer::parseObject()` and  `JsonBuffer::parseArray()` have been pulled down to the derived classes `DynamicJsonBuffer` and `StaticJsonBufferBase`.
+>
+> This means that if you have code like:

+> - `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!

-Arduino JSON library
-====================
-
-[![Build Status](https://travis-ci.org/bblanchon/ArduinoJson.svg?branch=master)](https://travis-ci.org/bblanchon/ArduinoJson) [![Coverage Status](https://img.shields.io/coveralls/bblanchon/ArduinoJson.svg)](https://coveralls.io/r/bblanchon/ArduinoJson?branch=master)
-
-*An elegant and efficient JSON library for embedded systems.*
-
-It's design to have the most intuitive API, the smallest footprint and works 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.
-
-Features
---------
-
-* JSON decoding
-* JSON encoding (with optional indentation)
-* Elegant API, very easy to use 
-* Fixed memory allocation (no malloc)
-* Small footprint
-* MIT License
-
-Quick start
------------
-
-#### Decoding / Parsing
-   
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
-
-    StaticJsonBuffer<200> jsonBuffer;
-
-    JsonObject& root = jsonBuffer.parseObject(json);
-
-    const char* sensor = root["sensor"];
-    long time          = root["time"];
-    double latitude    = root["data"][0];
-    double longitude   = root["data"][1];
-
-#### Encoding / Generating
-   
-    StaticJsonBuffer<200> jsonBuffer;
-
-    JsonObject& root = jsonBuffer.createObject();
-    root["sensor"] = "gps";
-    root["time"] = 1351824120;
-
-    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
-
-    root.printTo(Serial);
-    // This prints:
-    // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
-

-Documentation
--------------
-
-The documentation is available online in the [Arduino JSON wiki](https://github.com/bblanchon/ArduinoJson/wiki) 
-
-Testimonials
-------------
-
-From Arduino's Forum user `jflaplante`:
-> 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!!

+## Quickstart
+
+### Deserialization
+
+Here is a program that parses a JSON document with ArduinoJson.
+
+```c++
+char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
+
+DynamicJsonDocument doc(1024);
+deserializeJson(doc, json);
+
+const char* sensor = doc["sensor"];
+long time          = doc["time"];
+double latitude    = doc["data"][0];
+double longitude   = doc["data"][1];
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/doc/decoding/?utm_source=github&utm_medium=readme)
+
+### Serialization
+
+Here is a program that generates a JSON document with ArduinoJson:
+
+```c++
+DynamicJsonDocument doc(1024);
+
+doc["sensor"] = "gps";
+doc["time"]   = 1351824120;
+
+JsonArray data = doc.createNestedArray("data");
+data.add(48.756080);
+data.add(2.302038);
+
+serializeJson(doc, Serial);
+// This prints:
+// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+```

+// Use String objects sparingly, because ArduinoJson duplicates them in the

+  // sensor = obj["sensor"]; // <-  error "ambiguous overload for 'operator='"
+  // As a workaround, you need to replace by:
+  sensor = obj["sensor"].as<String>();
+
+  // You can set a String to a JsonObject or JsonArray:
+  // WARNING: the content of the String will be duplicated in the JsonDocument.

+
+  // You can also concatenate strings
+  // WARNING: the content of the String will be duplicated in the JsonDocument.

+
+  // You can compare the content of a JsonObject with a String
