-#### Nginx configuration
-
-GitLab 8.3 introduced major changes in the NGINX configuration. Ensure you're
-still up-to-date with the latest changes:
-
-```sh
-# For HTTPS configurations
-git diff origin/8-3-stable:lib/support/nginx/gitlab-ssl origin/8-4-stable:lib/support/nginx/gitlab-ssl
-
-# For HTTP configurations
-git diff origin/8-3-stable:lib/support/nginx/gitlab origin/8-4-stable:lib/support/nginx/gitlab
-```
-
-If you are using Apache instead of NGINX please see the updated [Apache templates].
-Also note that because Apache does not support upstreams behind Unix sockets you
-will need to let gitlab-workhorse listen on a TCP port. You can do this
-via [/etc/default/gitlab].

 #### Init script
 
 We updated the init script for GitLab in order to set a specific PATH for gitlab-workhorse.
