Is this necessary? I'd like to use the package in enzyme to avoid having to recopy/paste the symbols for better debugging names, but at hard dep in enzyme proper on a version of react isn't gonna work. This seems safe since nothing explicitly depends on React in here?
* Support ForwardRef type of work in TestRenderer and ShallowRenderer.
* Release script now updates inter-package dependencies too (e.g. react-test-renderer depends on react-is).
