As detailed in Jacob Rossi’s article for Smashing Magazine, the new engine began as a fork of MSHTML.dll but has since diverged very quickly. By making this split, we were able to keep the major subsystem investments made over the last several years, while allowing us to remove document modes and other legacy IE behaviors from the new engine. On the other hand, our legacy engine (MSHTML.dll) can remain largely unchanged (outside of security and other high priority fixes) to help guarantee legacy compatibility for our enterprise customers.For users that upgrade to Windows 10, the engine will be evergreen, meaning that it will be kept current
Sorry for asking if I've missed public knowledge here, but I can't recall having read about this: will Edge be available to Windows 8.1? or is it Windows 10 only?Upgrading from, say, Firefox 37 to 38 is easy and very transparent to the user. That is the magic wand. Requiring users to upgrade their OS in order to upgrade the browser is what makes the magic wand go away :( If users need to do that (no matter if the OS upgrade is free or not), then migration will be much slower.Since graphics and audio needs often go hand in hand, especially for games, I wonder, if Edge won't be available in Win8.1, will IE11 have Web Audio support? Or is development on new features for IE11 effectively frozen at this point of time?2015-06-19 22:54 GMT+03:00 Florian Bösch <email@example.com>:I should also perhaps point out this feedback here: https://wpdev.uservoice.com/forums/257854-microsoft-edge-developer/suggestions/6509607-auto-update-older-ie-versionsAuto Update Older IE Versions
Force older versions of Internet Explorer to automatically update.Which is the top-rated feedback on the Edge feedback site. And this didn't mean that updating "the latest supported version of Internet Explorer for that platform". That's an interpretation of update that's not shared by neither users nor developers. Update means you'll magicwand zap all those older versions with Edge.
