In early May there was the announcement that Attachmate was letting go of all Mono developers (Phoronix was, again, the first to break the story) following their acquisition of Novell/SUSE. Following that, Miguel de Icaza started a new company to foster future growth of the Mono platform. Last month there was then the hand-off of Mono to Xamarin (Miguel's new company) and this afternoon there is now the first official release of Xamarin Mono...
I almost feel sorry for Miguel as he is desperately hanging on the .NET/Mono branch. There might be one or two bucks left in profit but with win8 promoting html5/js on the application level and still mostly uses c++ on core level the platform starts falling apart.
