Microsoft presented the Windows 8.1 Preview version of the operating system but also the new features of the Internet Explorer 11 web browser.
Just like the next version of the Windows 8 operating system, Internet Explorer 11 is available as a Preview only for those who install the Windows 8.1 Preview version, however IE 11 will also arrive for Windows 7 at a later date.
From a technology point of view, the most important new features are support for WebGL adn SPDy. The WebGL software interface, used for hardware acceleration when displaying 2D and 3D content was ignored by Microsoft until now because the company said it has serious security problems.
However, the standard has evolved, it’s security was improved and WebGL will come with the Internet Explorer 11 web browser and you can use it for displaying graphic content.
A pleasant surprise is also the implementation of SPDY, the compression protocol built by Google. Implemented in Chrome, Firefox and Opera web browser, SPDY is an open network protocol that provides faster transfer speeds than the HTTP protocol by using data compression.
Along with these two new technologies, Microsoft also improved support for HTML5 Video, and Internet Explorer 11 promises a better experience without the need of additional extensions and full support for MPEG-DASH, however, WebRTC will have to wait a little bit longer.
Functionality wise, Internet Explorer 11 comes with many interesting chances. The large dimensions tabs from the Modern UI version have been replaced with standard tabs. Furthermore, the Modern UI version allows you to open more than 10 tabs at the same time.
You can also create dynamic Live Tiles for your favorite websites, Snap View with two windows or with the window of another application, integrating phone numbers with Skype and the possibility of editing your favorite websites list directly from the Modern UI.
Internet Explorer 11 final will arrive at the same time with the release of the Windows 8.1, however the precise release date is not known at this time.
