4.0 stabilization

[avtrujillo]

Hi,

What contributions or actions are needed in order to stabilize version 4.0 of this crate?

Hey @avtrujillo, I'll probably stabilize 4.0 soon after stabilizing oauth2 5.0.

Since both of these versions had major breaking changes, I'd like to wait another couple of months to see if additional issues get filed that might require further breaking changes to fix. In the meantime, the latest alpha releases should be safe to use in production; they're just not guaranteed to be API stable.
