add versioning

Software firewalls should list Second Life as a "trusted" program. We highly recommend turning on any notification for blocked network activity. You should frequently monitor your software firewall settings, as some versions change their own settings in an attempt to provide tighter security.

You need to consult the documentation for your software, or go to the manufacturer's website for details on how to configure your internet security software. Linden Lab cannot provide support for third-party software.

Don't forget the built-in Windows Firewall; certain system updates may cause the Windows Firewall to re-enable itself. You can find the Windows Firewall in the Control Panel, under Security Center.

Warning: If you're using wireless networking, it may not provide a stable and fast enough connection for Second Life.
