-Arduino JSON: change log
-========================
+ArduinoJson: change log
+=======================
 
-v4.1
-----
+v6.6.0-beta (2018-11-13)
+-----------
 
-* Added DynamicJsonBuffer (issue #19)
+* Removed `JsonArray::is<T>(i)` and `JsonArray::set(i,v)`
+* Removed `JsonObject::is<T>(k)` and `JsonObject::set(k,v)`
+* Replaced `T JsonArray::get<T>(i)` with `JsonVariant JsonArray::get(i)`
+* Replaced `T JsonObject::get<T>(k)` with `JsonVariant JsonObject::get(k)`
+* Added `JSON_STRING_SIZE()`
+* Replacing or removing a value now releases the memory
+* Added `DeserializationError::code()` to be used in switch statements (issue #846)
 
-v4.0
-----
+v6.5.0-beta (2018-10-13)
+-----------
 
-* Unified parser and generator API (issue #23)
-* Updated library layout, now requires Arduino 1.0.6 or newer
+* Added implicit conversion from `JsonArray` and `JsonObject` to `JsonVariant`
+* Allow mixed configuration in compilation units (issue #809)
+* Fixed object keys not being duplicated
+* `JsonPair::key()` now returns a `JsonKey`
+* Increased the default capacity of `DynamicJsonDocument`
+* Fixed `JsonVariant::is<String>()` (closes #763)
+* Added `JsonArrayConst`, `JsonObjectConst`, and `JsonVariantConst`
+* Added copy-constructor and copy-assignment-operator for `JsonDocument` (issue #827)
 
-**BREAKING CHANGE**: API changed significantly, see [Migrating code to the new API](https://github.com/bblanchon/ArduinoJson/wiki/Migrating-code-to-the-new-API).
+v6.4.0-beta (2018-09-11)
+-----------
 
+* Copy `JsonArray` and `JsonObject`, instead of storing pointers (issue #780)
+* Added `JsonVariant::to<JsonArray>()` and `JsonVariant::to<JsonObject>()`
 
-v3.4
-----
+v6.3.0-beta (2018-08-31)
+-----------
 
-* Fixed escaped char parsing (issue #16)
+* Implemented reference semantics for `JsonVariant`
+* Replaced `JsonPair`'s `key` and `value` with `key()` and `value()`
+* Fixed `serializeJson(obj[key], dst)` (issue #794)
 
+> ### 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!
 
-v3.3
-----
+v6.2.3-beta (2018-07-19)
+-----------
 
-* Added indented output for the JSON generator (issue #11), see example bellow.
-* Added `IndentedPrint`, a decorator for `Print` to allow indented output
+* Fixed exception when using Flash strings as object keys (issue #784)
 
-Example:
+v6.2.2-beta (2018-07-18)
+-----------
 
-    JsonOject<2> json;
-    json["key"] = "value";
-    json.prettyPrintTo(Serial);
+* Fixed `invalid application of 'sizeof' to incomplete type '__FlashStringHelper'` (issue #783)
+* Fixed `char[]` not duplicated when passed to `JsonVariant::operator[]`
 
-v3.2
-----
+v6.2.1-beta (2018-07-17)
+-----------
 
-* Fixed a bug when adding nested object in `JsonArray` (bug introduced in v3.1).

-v3.1
-----
+v6.2.0-beta (2018-07-12)

-Old generator API:
+> ### BREAKING CHANGES
+>
+> #### Non quoted strings
+>
+> Non quoted strings are now forbidden in values, but they are still allowed in keys.
+> For example, `{key:"value"}` is accepted, but `{key:value}` is not.
+>
+> #### Preformatted values
+>
+> Old code:
+>
+> ```c++
+> object["values"] = RawJson("[1,2,3,4]");
+> ```
+> 
+> New code:
+> 
+> ```c++
+> object["values"] = serialized("[1,2,3,4]");
+> ```

+> 
+> #### Deserialization
+>

+> 
+> ```c++
+> DynamicJsonBuffer jb;
+> JsonObject& obj = jb.parseObject(json);
+> if (obj.success()) {
+> 
+> }
+> ```
+> 
+> New code:

+> DeserializationError error = deserializeJson(doc, json);
+> if (error) {
+> 
+> }
+> JsonObject& obj = doc.as<JsonObject>();
+> ```
+> 
+> #### Serialization
+> 
+> Old code:

-    double longitude = root["data"][1];
+v5.13.1
+-------
 
-v2.1
-----
+* Fixed `JsonVariant::operator|(int)` that returned the default value if the variant contained a double (issue #675)
+* Allowed non-quoted key to contain underscores (issue #665)
 
-* Fixed case `#include "jsmn.cpp"` which caused an error in Linux (issue #6)
-* Fixed a buffer overrun in JSON Parser (issue #5)
+v5.13.0
+-------
 
-v2.0
-----
+* Changed the rules of string duplication (issue #658)
+* `RawJson()` accepts any kind of string and obeys to the same rules for duplication
+* Changed the return type of `strdup()` to `const char*` to prevent double duplication

-* Added JSON encoding (issue #2)
-* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
+> ### New rules for string duplication
+>
+> | type                       | duplication |
+> |:---------------------------|:------------|
+> | const char*                | no          |
+> | char*                      | ~~no~~ yes  |
+> | String                     | yes         |
+> | std::string                | yes         |
+> | const __FlashStringHelper* | yes         |
+>
+> These new rules make `JsonBuffer::strdup()` useless.
 
-**Breaking change**: you need to add the following line at the top of your program.
+v5.12.0

-v1.2
-----
+> ### How to use the new feature?
+>
+> 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";
+> ```
 
-* Fixed error in JSON parser example (issue #1)

+> ### 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:
+>
+> ```c++
+> void myFunction(JsonBuffer& jsonBuffer);
+> ```
+>
+> you need to replace it with one of the following:
+>
+> ```c++
+> void myFunction(DynamicJsonBuffer& jsonBuffer);

+> - `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]}

-
-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;
+deserializeJson(doc, json);
+
+JsonObjectRef root = doc.as<JsonObject>();
+const char* sensor = root["sensor"];
+long time          = root["time"];
+double latitude    = root["data"][0];
+double longitude   = root["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;
+
+JsonObject root = doc.to<JsonObject>();
+root["sensor"] = "gps";
+root["time"] = 1351824120;
+
+JsonArray data = root.createNestedArray("data");
+data.add(48.756080);
+data.add(2.302038);
+
+serializeJson(doc, Serial);
+// This prints:
+// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/doc/encoding/?utm_source=github&utm_medium=readme)
