Update PropTypes

[uzer-ua]

Is this library still maintained?

You want to upgrade PropTypes in the dependencies list. At least make non-strict version (e.g. ^15.6.0)
15.6.0 have known vulnerabilities (prop-types - fb.js - ... - node-fetch) and automatic scanning tools like WhiteSource are failing.

Using 3.0.0.alpha7

I haven't needed this library for years, so I've not contributed anything, and it appears most people just fork it and don't contribute.

Feel free to open a PR, but I can't promise I'll get it merged any time soon.

In the meantime you can use one of:
