This is going to be the v4.
Expected improvements:
- More reliable due to static typing.
- Bump of performance.
- Improvement of logging.
- Authelia can be shipped as a single binary.
- Will likely work on ARM architecture.
* Removal of the Redirect header sent by Authelia /api/verify endpoint.
* Authelia does not consume Host header anymore but X-Forwarded-Proto and X-Forwarded-Host
to compute the link sent in identity verification emails.
* Authelia used Host header as the application name for U2F authentication but it's now using
X-Forwarded-* headers.
