Hello all,

We have [written previously][0] about upcoming changes to how media is structured in the HTML output of MediaWiki's wikitext parser. You can read more about it in [the FAQ][1].

Over the past many months, we have been [gradually rolling out these changes][2], first to test wikis, then to a number of early adopter wikis that opted-in to help us identify and resolve issues (thank you for that), and finally to all group1 wikis.

In the coming weeks, we plan on enabling the changes on group2 wikis. This will be included in Tech News.

We have identified a number of gadgets, user scripts, and MediaWiki:Common.(css|js) pages that required forward compatible changes, and have worked with interface administrators to get those [changes applied beforehand][3][4][5].

However, should you notice any visual differences in how media is displayed or scripts that are no longer working, please file tasks in Phabricator with the [Parsoid-Read-Views (Phase 0 - Parsoid-Media-Structure)][6] project tag.

Thanks, The Content Transform Team
