What is the latest version and how do I get it?:

For the latest patch check the Blizzard Entertainment FTP site at ftp://ftp.blizzard.com/pub/*
Or log on to Battle.net through the multiplayer option. If there is a newer version then the one you are using the patch(s) will be downloaded and installed.

*You need to be connected to the internet to access the Blizzard FTP site.
