	- Bug #1873: authenticateNTLMFixErrorHeader: state 4.
	- Document the https_port vhost option, useful in combination with
	  a wildcard certificate
	- Document the existence of connection pinning / forwarding of NTLM
	  auth and a few other features overlooked in the release notes.

	  leak checking enabled
