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:

#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.

// 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>()).

How to install

There are several ways to install ArduinoJson, from simpler to more complex:

  1. Use the Arduino Library Manager
  2. Download ArduinoJson-v6.11.0.h put it in your project folder
  3. Download ArduinoJson-v6.11.0.zip and extract it in you libraries folder

Note: ArduinoJson-v6.11.0.h and ArduinoJson-v6.11.0.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.
