Hi all!

I have just released the first (and probably final) Release Candidate for Gophernicus version 3.1. This brings a host of improvements to gophernicus, notably including:

- OpenBSD pledge and unveil support. - A new filetypes system. - `-nH` to disable HTTP responses. - A new build system. - A manual page. - An official Debian package coming in the next stable release for 3.1! - A wide variety of bug fixes.

I would really appreciate testing, especially of the new build system. You can get sources and binaries here: https://github.com/gophernicus/gophernicus/releases/tag/3.1rc1.

Please read INSTALL.md, the process has changed (you now need to run `./configure` first).

If you are a deb package user, please either:

1. wait for the official Debian package to come into your repositories and apt will handle the rest. 2. if you want the new releases sooner, please compile and install manually, preferably to `/usr/local` or `/opt` as not to mess with the system package. Then, when the new Debian package comes, you can easily remove the manual install.

Along with this release we are now distributing binaries. There are currently two binaries, and there will be more added for the final release. The current two are:

1. An x86_64 glibc binary, linked against glibc 2.30, without libwrap. 2. An x86_64 static binary, which will work on any system, even running alternative libcs or older versions of glibc, without libwrap.
