First version of yiisoft/json standalone package was released.

The package provides methods to encode and decode JSON.

• It always throws \JsonException instead of returning false on error.
• It has sensible defaults, so you don't have to specify flags all the time.
• It has handy method to encode for HTML safely.
• It handles \JsonSerializable, \DateTimeInterface, and \SimpleXMLElement well.

Usage example is available in readme.
