Bootstrap Go implementation of Authelia.

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.

 Since Authelia is still under active development, it is subject to breaking changes. We then recommend you don't blindly use the latest
 Docker image but pick a version instead and check this file before upgrading. This is where you will get information about breaking changes and about what you should do to overcome those changes.

+## Breaking in v4.0.0
+
+Authelia has been rewritten in Go for better performance and reliability.
+
+### Model of U2F devices in MongoDB
+
+The model of U2F devices stored in MongoDB has been updated to better fit with the Go library handling U2F keys.
+
+### Removal of flag secure for SMTP notifier
+
+The go library for sending e-mails automatically switch to TLS if possible according to https://golang.org/pkg/net/smtp/#SendMail.
+
 ## Breaking in v3.14.0

 ### Headers in nginx configuration
