Microsoft's forthcoming Windows 10 OS brings many new changes in terms of architecture and design. One of those updates is in regards to MDL2 also known as Microsoft Design Language 2.0. This term refers to the change in controls, fonts, and iconography found in the desktop and mobile versions of Windows 10.
Martin Anderson, who's interested in general technology and Microsoft's platforms, has cobbled together a neat image graphic (original size). It compares and contrasts the design language found in Windows and Windows Phone 8.1 to the new framework found in Windows 10 for mobile and desktop.
The template explicitly compares controls e.g. switches, toggles, pickers, dialog windows and gives a visual overview of how the design language has evolved.
