- Installer adds ispconfig user to Apache group on Fedora/CentOS so that nginx/PHP-FPM can access /etc/squirrelmail and serve SquirrelMail for the ISPConfig vhost.
- Added session.save_path and upload_tmp_dir settings to the PHP-FPM pool definitions.

- Added support for the /etc/nginx/sites-available and /etc/nginx/sites-enabled directories on Fedora/CentOS to the installer.

Changed PHP-FPM socket directory from /var/run/php5-fpm to /var/lib/php5-fpm because /var/run is cleand up on reboot.

- Added UFW firewall support.

- Added support for new default named.conf views layout.
