Exclusively for browsers from Microsoft : Iternet Explorer versions 8 through 11 and Edge . For the first time, IE8 was recognized by the browser, when all versions of the engine were included in the package, starting from 5. Different sets of available engines were delivered in different IE releases. This meta tag dictates to the browsers of this nice family which version of the engine to use to display the page. Browsers Edge today do not have the ability to switch to Internet Explorer modes, only emulate their behavior, as well as IE perceives the Edge instruction, as an order to use the latest available engine.
