Looks brill. Noticed a fair few of them in: Just mentioning #3164 too as it'll need the new ie8.test.js test adjusting Note: Not necessarily related, but all the Sass "tooling" tests spin up the Review app as they're named to match the "JavaScript behaviour tests" project. Annoying you could use |

@claireashworth I've added a changelog entry for this, but it feels a little clunky (especially the title) – would you like to take a look now or happy to take a look when we come to do the release? |

or
Stop using the mixins and breakpoint settings for generating IE8 stylesheets
or
Stop using the deprecated IE8 mixins and settings.
It depends how much detail you want in the header.

@36degrees I've made some suggestions, but the rest looks fine to me.

We'll be removing IE8 support in v5.0. Following our guidance for deprecating and removing features, deprecate the Sass settings and mixins used for building IE8 specific stylesheets:
$govuk-is-ie8setting$govuk-ie8-breakpointsettinggovuk-if-ie8mixingovuk-not-ie8mixinUpdate references to the mixins within GOV.UK Frontend so that they do not generate warnings – we only want warnings to be generated where service teams are using the
govuk-if-ie8andgovuk-not-ie8mixins in their own code.Suppress IE8 related warnings when generating the IE8 stylesheets for the review app or for the
distversion of GOV.UK Frontend.Deprecating these features communicates this intent to service teams and allows them to make changes ahead of time, reducing the effort involved in upgrading to the next major version.
Closes #3163
