How to Install Wine 2.21 Released via PPA on Ubuntu

   Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OSX, & BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.

• Still more metafile support in GdiPlus.
• Indirect draws support in Direct 3D.
• Calling convention fixes on ARM.
