Wine stands for "Wine is not an emulator" and it is an open source command-line software that's capable of translating Windows API calls into POSIX calls on-the-fly for integrating Windows applications into your Linux/UNIX desktop. For regular Linux users, the above means that the Wine software will allow them to run applications which are designed to be installed only on Microsoft Windows operating systems.

It's not a virtual machine or an emulator
However, Wine should not be confused with a virtual machine or an emulator. It provides binary compatibility, support for graphics, sound interaction, as well as support for modems, networks, scanners, tablets, keyboards, and other devices. The software’s API allows developers to integrate Wine in their projects, and as a result, numerous graphical user interfaces, both free and commercial, appeared on the Internet over the years.

The Wine development release 1.7.43 is now available.
What's new in this release:

• Improved support for Shell Browser windows.
• Some more API Sets libraries.
• Read/write operations support with built-in devices.
• Major Catalan translation update.
• Support for WoW64 mode on ARM64.
• Various bug fixes.

The source is available now. Binary packages are in the process of being built, and will appear soon at their respective download locations.
