BREAKING CHANGES ⚠️

Non quoted strings

Non quoted strings are now forbidden in values, but they are still allowed in keys.
For example, {key:"value"} is accepted, but {key:value} is not.

Preformatted values

Old code:

object["values"] = RawJson("[1,2,3,4]");

New code:

object["values"] = serialized("[1,2,3,4]");

How to install

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

1. Use the Arduino Library Manager
2. Download ArduinoJson-v6.2.0-beta.h put it in your project folder
3. Download ArduinoJson-v6.2.0-beta.zip and extract it in you libraries folder

Note: ArduinoJson-v6.2.0-beta.h are ArduinoJson-v6.2.0-beta.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.
