Breaking changes

JsonBuffer::parseObject() and JsonBuffer::parseArray() have been pulled down to the derived classes DynamicJsonBuffer and StaticJsonBufferBase.

This means that if you have code like:

void myFunction(JsonBuffer& jsonBuffer);

you need to replace it by one of the following:

void myFunction(DynamicJsonBuffer& jsonBuffer);
void myFunction(StaticJsonBufferBase& jsonBuffer);
template<typename TJsonBuffer> void myFunction(TJsonBuffer& jsonBuffer);

How to use the new Stream feature?

If you have something like:

char json[256];
size_t n= stream.readBytes(json, sizeof(json));     
json[n] = 0;

JsonObject& root = jsonBuffer.parseObject(json);

then you can replace by:

JsonObject& root = jsonBuffer.parseObject(stream);

but don't forget to increase the size of the JsonBuffer because it now has to hold a copy of the input.

ArduinoJson 5.7.3

Changes since 5.7.2

• Added an printTo(char[N]) and prettyPrintTo(char[N]) (issue #292)
• Added ability to set a nested value like this: root["A"]["B"] = "C" (issue #352)
• Renamed *.ipp to *Impl.hpp because they were ignored by Arduino IDE (issue #396)

ArduinoJson 5.7.2

Changes since 5.7.1

• Made PROGMEM available on more platforms (issue #381)
• Fixed PROGMEM causing an exception on ESP8266 (issue #383)

ArduinoJson 5.7.1

Changes since 5.7.0

• Added support for PROGMEM (issue #76)
• Fixed compilation error when index is not an int (issue #381)

ArduinoJson 5.7.0

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);
