Which package to download?

If you are running the official Arduino IDE, download ArduinoJson-v5.5.1.zip.
You can also use the library manager from the IDE; it will download the library for you.

If you are running an alternative IDE (like Energia or Stino), download ArduinoJson-v5.5.1-old-layout.zip.
This package has the legacy library layout that was supported by older versions of the Arduino IDE.

ArduinoJson 5.5.0

Changes since v5.4.0

• Added JsonVariant::success() (issue #279)
• Renamed JsonVariant::invalid<T>() to JsonVariant::defaultValue<T>()
