IE 11 UserAgent match for detecting the browser name and the versions

Hi All, 

I am using IE browser and i see that the latest IE 11 version, has the userAgent string without MSIE!!!

And most of the time, i used to detect IE browser name and version using this string, using  regular expression string to match. 

Can anyone tel me , why this(MSIE) has been removed from the useragent? and also BrowserDetect.IE will return as false!!

I need help in detecting the IE version of the browser....
