Release v0.73.0

Acknowledgements

A special thanks to our contributor @sanyo0714 (#412), as well as to everyone who helped us with this release!

Added

• The --hosts-file-enabled and the --hosts-files options, which control the preliminary resolving A, AAAA and PTR requests from hosts (5) files before using the upstream servers.

Note

The functionality is enabled and uses the OS-specific hosts files by default. To disable it, use --hosts-file-enabled=false option.

Changed

• The upstream.AddressToUpstream now validates the host as a domain name, as opposed to the hostname validation used before (#411). The same also applies to the proxy.ParseUpstreamConfig function.
• The proxy.MessageConstructor interface has been changed to include one additional method NewMsgNODATA.

Removed

• proxy.CheckDisabledAAAARequest function, use proxy.RequestHandler to halt AAAA requests.
• proxy.GenEmptyMessage function.
