Introduced in branch:
8.x
Description:
We now send the X-UA-Compatible HTTP header to force IE to use the most recent rendering engine.
This also prevents the IE compatibility mode button to appear if certain markup makes IE think it is dealing with legacy pages (such as when using IE conditional classes on the html tag.)
This is the HTTP header that now appears in Drupal 8:
X-UA-Compatible: IE=edge
Impacts:
Site builders, administrators, editors
