Changes (by jonsurrell):

 * version:   => 4.8


Comment:

 I investigated a bit to ensure these browsers should not be supported.

 [https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
 According to this make post, IE8, IE9 and IE10 support was dropped in
 WordPress 4.8.]

 IE10 removed support for conditional comments. **No browsers supported by
 WordPress use conditional comments.**
