* 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)

Changes since v5.6.7

  • 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:

#define ARDUINOJSON_USE_ARDUINO_STRING 0
JsonVariant value1 = myObject.get("myKey");
JsonVariant value2 = myArray.get(0);

New code:

#define ARDUINOJSON_ENABLE_ARDUINO_STRING 0
#define ARDUINOJSON_ENABLE_STD_STRING 1
JsonVariant value1 = myObject.get<JsonVariant>("myKey");
JsonVariant value2 = myArray.get<JsonVariant>(0);
