As you may know, Wine (Wine Is Not An Emulator) is an open-source compatibility layer software app that enables the Linux and Unix users to run Windows software on their systems, via the Winelib software library.
At first, Wine was an acronym for WINdows Emulator, but later, the name developers have shifted to the recursive backronym, “Wine is not an emulator”, to highlight that no emulation occurs when running Windows software.
The latest version available is Wine 1.8, being under development of 17 months and receiving around 13.000 changes. For more information, see the release notes.
Recently, it has been added to the default Wine Stable PPA, for an easier installation. For installation instructions, for Ubuntu 15.10 Wily Werewolf, Ubuntu 14.04 Trusty Tahr, Linux Mint 17.x, Elementary OS 0.3 Freya and derivative systems, see the instructions in this article.
