If your tool does not read user information from Wiki Replicas, feel free to ignore this email.
Temporary accounts [0] are starting to be rolled out, and since yesterday they are enabled on a few smaller wikis: Czech Wikiversity, Igbo Wikipedia, Italian Wikiquote, Swahili Wikipedia, and Serbo-Croatian Wikipedia. [1]
Temporary Accounts modify the ways MediaWiki stores anonymous users in database tables. If you manage a tool that reads user information for anonymous users, you should check the page "How should I update my code?" [2] to find out if you need to make changes to your tool. You can use the wikis listed above to test that your tool is working correctly.
If you have questions or if you want to report an issue, you can file a Phabricator task as a subtask of [3].
