Hi everybody!

A couple of weeks ago we started switching the backend used by the ORES extension which is used by the Recent Changes filters.

After fixing the issue that was caused in some wikis (https://phabricator.wikimedia.org/T343308) the Machine Learning team started rolling out the change again.

We have already deployed the changes to fiwiki and itwiki and will continue with the rest of the wikis starting from next week.

This change is using Lift Wing (https://wikitech.wikimedia.org/wiki/Machine_Learning/LiftWing) to get revision scores instead of ORES, and is a necessary step in the process of deprecating ORES (for more info please refer to the "ORES to Lift Wing Migration" email).

The purpose of this change is to use exactly the same models which are also deployed on Lift Wing so there shouldn't be anything different for our users.

If however you see anything out of the ordinary, feel free to contact

Thank you!
