I am happy to announce that we now support a newer version of NGINX for new servers running Ubuntu 18.04. This is the culmination of a lot of work to include various modules, so we're pretty pleased about this one! In fact, the compilation process was such a challenge, we decided to open source our work here!
Any new servers created from now will benefit from this NGINX update immediately; you can also use an application update to upgrade existing servers (although this is of course a less desirable approach). See the list of the modules we now support by default in our help documentation.
Note: Although we have some NGINX configuration changes coming, your existing configurations should still work with the new NGINX version; please contact support if you encounter any issues around that!
