No, this is the difference between revisions page in namespace 4, canonical "Project", "Викисловарь".

Because 512126 has not been merged yet and the fix for 1.34.0-wmf.6 branch was not ported to master branch, resulting in 1.34.0-wmf.7 branch not including the fix, resulting in bug regressions.

This will affect all wikis using 1.34.0-wmf.7, for now affect group0 and group1. Will soon affect group2. (thursday train at 12:00–13:00 UTC)
