## Bugs Fixed

1. The pip installable ‘mod_wsgi’ package was failing to install on OpenShift and Heroku as `mod_wsgi-apxs` isn’t used for tarball based installs.

## Features Changed

1. For `mod_wsgi-express`, only the web server type is now shown in the server tokens sent back in the `Server` response header. This prevents users from knowing any specifics and thus using that to determine possible vulnerabilities.

## New Features

1. Set environment variables from `apachectl` for `mod_wsgi-express` about the server environment which can be used in additional Apache configuration included into the generated configuration. The environment variables are:

- MOD_WSGI_SERVER_ROOT - This is the directory where the generated configuration files, startup scripts, etc were placed.
- MOD_WSGI_WORKING_DIRECTORY - This is the directory which will be used as the current working directory of the process. Would default to being the same as `MOD_WSGI_SERVER_ROOT` if not overridden.
- MOD_WSGI_LISTENER_HOST - The host name or IP on which connections are being accepted. This should only be used if the Apache configuration variable `MOD_WSGI_WITH_LISTENER_HOST` is defined.
- MOD_WSGI_HTTP_PORT - The port on which HTTP connections are being accepted.
- MOD_WSGI_HTTPS_PORT - The port on which HTTPS connections are being accepted. This should only be used if the Apache configuration variable `MOD_WSGI_WITH_HTTPS` is defined.
- MOD_WSGI_MODULES_DIRECTORY - The directory where the Apache modules are installed.
- MOD_WSGI_RUN_USER - The user that the WSGI application will be run as.
- MOD_WSGI_RUN_GROUP - The group that the WSGI application will be run as.

2. Added `X-Client-IP` to list of possible trusted headers indicating the true remote address of client when passing through a proxy.
