“Microsoft Edge (codenamed “Project Spartan”) is the new default browser built for Windows 10. It provides WebNote for native page annotation and sharing capabilities, reading view and reading list support, and Cortana integration that delivers more info and task support throughout the browsing experience.
For web developers, Microsoft Edge brings an all new rendering engine, built to be interoperable with the modern web. Microsoft Edge is a clean break from the past focusing on interoperability with modern web standards and browsers so you can write modern markup once for all browsers. Microsoft Edge and its new engine will be updated as a service with Windows 10, so you be sure that everyone browsing your site or using your web app with Microsoft Edge is always on the same page.”
