 ### Internet Explorer
 
 Internet Explorer has a compatibility view mode that allows newer versions (IE8+) to run as an older version. Browser will always return the navigator version, ignoring the compatibility view version, when defined. If you need to get the engine's version, you have to use `Browser#msie_version` and `Browser#msie_full_version`.
