How to use the new feature?

If you have a block like this:

const char* ssid = root["ssid"];
if (!ssid)
  ssid = "default ssid";

You can simplify like that:

const char* ssid = root["ssid"] | "default ssid";

How to install

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

  1. Use the Arduino Library Manager
  2. Download ArduinoJson-v5.12.0.h put it in your project folder
  3. Download ArduinoJson-v5.12.0.zip and extract it in you libraries folder

Note: ArduinoJson-v5.12.0.h are ArduinoJson-v5.12.0.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.
