Hello Linux Geeksters. As you may know, Wine is a popular emulator for Linux, allowing users to install Windows programs on Unix systems. The latest version available is Wine 1.7.2, which has been released a while ago. For a full list of improvements, see the official changelog.

It will be available soon in the official Wine Ubuntu PPA, so for a successful installation just do:
