Mono Relicensed MIT
At the Mono Project blog, Miguel de Icaza announced that the Mono runtime has been relicensed, moving from a dual-license slate (with LGPLv2 and proprietary optiona) to the MIT license. The Mono compiler and class libraries were already under the MIT license and will remain so. "Moving the Mono runtime to the MIT license removes barriers to the adoption of C# and .NET in a large number of scenarios, embedded applications, including embedding Mono as a scripting engine in game engines or other applications." De Icaza notes that Xamarin (which was recently acquired by Microsoft) had developed several proprietary Mono modules in recent years; these will also now be released under the MIT license.
