Wagtail now has official accessibility support targets: we are aiming for compliance with `WCAG2.1 <https://www.w3.org/TR/WCAG21/>`_, AA level. WCAG 2.1 is the international standard which underpins many national accessibility laws.
Wagtail isn't fully compliant just yet, but we have made many changes to the admin interface to get there. We thank the UK Government (in particular the CMS team at the Department for International Trade), who commissioned many of these improvements.
Again, this is still a work in progress –if you are aware of other existing accessibility issues, please do `open an issue <https://github.com/wagtail/wagtail/issues?q=is%3Aopen+is%3Aissue+label%3AAccessibility>`_ if there isn't one already.

The icon font implementation has been changed to be invisible for screen-reader users, by switching to using `Private Use Areas <https://en.wikipedia.org/wiki/Private_Use_Areas>`_ Unicode code points. All of the icon classes (``icon-user``, ``icon-search``, etc) should still work the same, except for two which have been removed because they were duplicates:
