-ArduinoJson - C++ JSON library for IoT
-====================
-
-*An elegant and efficient JSON library for embedded systems.*
-
-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`.
-
-Features
---------
-
-* JSON decoding (comments are supported)
-* JSON encoding (with optional indentation)
-* Elegant API, very easy to use
-* Fixed memory allocation (zero malloc)
-* No data duplication (zero copy)
-* Portable (written in C++98)
-* Self-contained (no external dependency)
-* Small footprint
-* Header-only library
-* MIT License
-
-Works on
---------
-
-* Arduino boards: Uno, Due, Mini, Micro, Yun...
-* ESP8266, ESP32
-* Teensy
-* RedBearLab boards (BLE Nano...)
-* Intel Edison and Galileo
-* WeMos boards: D1...
-* Computers: Windows, Linux, OSX...
-* PlatformIO
-* Particle
-* Energia
-
-Quick start
------------
-
-#### Decoding / Parsing
-
-```c++
-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];
-```
-
-[See JsonParserExample.ino](examples/JsonParserExample/JsonParserExample.ino)
-
-Use [ArduinoJson Assistant](https://bblanchon.github.io/ArduinoJson/assistant/) to compute the buffer size.
-
-#### Encoding / Generating
-
-```c++
-StaticJsonBuffer<200> jsonBuffer;
-
-JsonObject& root = jsonBuffer.createObject();
-root["sensor"] = "gps";
-root["time"] = 1351824120;
-
-JsonArray& data = root.createNestedArray("data");
-data.add(48.756080);
-data.add(2.302038);
-
-root.printTo(Serial);
-// This prints:
-// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
-```
-
-[See JsonGeneratorExample.ino](examples/JsonGeneratorExample/JsonGeneratorExample.ino)
-
-Use [ArduinoJson Assistant](https://bblanchon.github.io/ArduinoJson/assistant/) to compute the buffer size.
-
-
-Documentation
--------------
-
-The documentation is available online in the [ArduinoJson Website](https://bblanchon.github.io/ArduinoJson/).
-
-The [ArduinoJson Assistant](https://bblanchon.github.io/ArduinoJson/assistant/) helps you get started with the library.

 ArduinoJson: change log
 =======================
 
+v5.13.4
+-------
+
+* Removed spurious files in the Particle library
+
+v5.13.3
+-------
+
+* Improved float serialization when `-fsingle-precision-constant` is used
+* Fixed `JsonVariant::is<int>()` that returned true for empty strings
+* Fixed `JsonVariant::is<String>()` (closes #763)
+
+v5.13.2
+-------
+
+* Fixed `JsonBuffer::parse()` not respecting nesting limit correctly (issue #693)
+* Fixed inconsistencies in nesting level counting (PR #695 from Zhenyu Wu)
+* Fixed null values that could be pass to `strcmp()` (PR #745 from Mike Karlesky)
+* Added macros `ARDUINOJSON_VERSION`, `ARDUINOJSON_VERSION_MAJOR`...
+
+v5.13.1
+-------
+
+* 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)
+
+v5.13.0
+-------
+
+* 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
+* Marked `strdup()` as deprecated
+
+> ### New rules for string duplication
+>
+> | type                       | duplication |
+> |:---------------------------|:------------|
+> | const char*                | no          |
+> | char*                      | ~~no~~ yes  |

+> | std::string                | yes         |
+> | const __FlashStringHelper* | yes         |
+>
+> These new rules make `JsonBuffer::strdup()` useless.
+
+v5.12.0
+-------
+
+* Added `JsonVariant::operator|` to return a default value (see below)
+* Added a clear error message when compiled as C instead of C++ (issue #629)
+* Added detection of MPLAB XC compiler (issue #629)
+* Added detection of Keil ARM Compiler (issue #629)
+* Added an example that shows how to save and load a configuration file
+* Reworked all other examples
+
+> ### How to use the new feature?
+>
+> If you have a block like this:
+>
+> ```c++
+> const char* ssid = root["ssid"];
+> if (!ssid)
+>   ssid = "default ssid";

+## 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]}";
+
+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];
+```
+
+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++
+StaticJsonBuffer<200> jsonBuffer;
+
+JsonObject& root = jsonBuffer.createObject();
+root["sensor"] = "gps";
+root["time"] = 1351824120;
+
+JsonArray& data = root.createNestedArray("data");
+data.add(48.756080);
+data.add(2.302038);
+
+root.printTo(Serial);
+// This prints:

+## Documentation
+
+The documentation is available on [arduinojson.org](https://arduinojson.org/?utm_source=github&utm_medium=readme), here are some shortcuts:
+
+* The [Examples](https://arduinojson.org/example/?utm_source=github&utm_medium=readme) show how to use the library in various situations.
+* The [API Reference](https://arduinojson.org/api/?utm_source=github&utm_medium=readme) contains the description of each class and function.
+* The [FAQ](https://arduinojson.org/faq/?utm_source=github&utm_medium=readme) has the answer to virtually every question.
+* The [ArduinoJson Assistant](https://arduinojson.org/assistant/?utm_source=github&utm_medium=readme) writes programs for you!
