We've reached the point in deployment of the Multi-Content Revisions changes where we're turning off the writing of data to deprecated fields. In particular, rev_text_id and ar_text_id will be 0 in all revisions, and rev_content_model, rev_content_format, and corresponding fields in the archive table will always be null. This has been the case on testwiki since October 29, and on the remaining group 0 wikis since a few minutes ago. Assuming no issues turn up, we plan to roll it out to group 1 on Thursday and group 2 early next week. If you find any MediaWiki bugs that seem as if they might be related to this change, please file them in Phabricator and tag #Core-Platform-Team.
