Similar to the earlier removal of text fields from the wiki replicas for comment storage refactors in Mediawiki, we are going to remove “user text” columns from the views that are deprecated in the Mediawiki schema to prepare for when they will actually be removed upstream.  The column drops are tracked and explained here  The tables with names such as <tablename>_compat will not see a difference in structure.  The change is scheduled for Monday, May 27th.

The fields that are dropping from the views are:
Ideally, tools that connect to the replicas should gather the information from the appropriate entries in the actor table instead, again, this is similar to the change for the comment table. The data is already there for you to start using.  The alternative is to try using the related <tablename>_compat table, which won’t be changing in a user-visible way at this time.
