If i am not wrong, this update is coming with new internet explorer?
Indeed. It will be delivered with IE11. So I suppose rendering and such will be faster/slightly better in some way, but the main attractions of IE11 for Windows Phone 8.1 are:
> Syncing of open tabs across all devices running Windows or Windows Phone 8.1
> Now can store and auto-complete user names and passwords, at your discretion
> Removed the stupid 6 tab limit
> Reading mode now available
> DataSense now more directly integrated into the browser, making it easier to manage your DataSense settings and making it more obvious to new users
> Refresh now on the address bar
> Now supports swipe right to go back, swipe left to go forward (just like on the desktop
> Now supports porn mo.... Erm, I mean, InPrivate Browsing >_>
