On our Kibana browser report, a lot of IE11 reported as IE7 which is very confusing to our whole engineering team. for example, given below user agent string
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3) , which is actually IE11, but it shows as IE7.0 on Kibana report.
We should use a similar algorithm to ie-truth to calculate real IE version.
Just logged a bug on github
