Hello @Graham87, we are starting work around improving wikidiff2 and we are starting the conversations around accessibility in better diffs. Do you have any feedback regarding accessibility improvements and screen reading users when using better diffs? Thank you.

At the moment I mostly check diffs by going in to the HTML source and searching for "diffch" ... which I've been doing for many years now. I'm generally alright with that, but of course it does fail horribly when line breaks are removed, etc. Recently more screen readers have better support for deletion/insertion annotation; when it comes to Windows screen readers, both JAWS and NVDA support reading them while NVDA supports moving between annotations. It could be nice to have some mode (enabled/disabled on the fly) that *only* shows the text that's changed and not the surrounding text.

Notes

• We should attempt to use ARIA annotations where appropriate to provide hints to screen readers
  • role="insertion" (W3C) and role="deletion" (W3C) — semantically denote HTML elements whose contents represent an insertion to or deletion from the overall document.

ARIA roles are necessary only when the semantic of the element with the role differs from the role assigned e.g. <div role="insertion"> is a change in semantic from "none" to "insertion", versus <ins>, which already carries the "insertion" semantic.
