Nginx 1.13.4

tarball: http://nginx.org/download/nginx-1.13.4.tar.gz (or wait for it to show up in your package manager)

The most notable change is the (new) mirror module which allows you to more transparently pass requests to your backends. Previously, this required modifying headers and potentially request body.
