Thread:Extension talk:Collection/Interest in or objection to option disabling use of PediaPress/reply (8)

I don't think this is related to this change. I don't know anything about the title page generation to check this out. Maybe you should open a new bug for this in bugzilla (https://bugzilla.wikimedia.org) or open a new discussion thread.

Maybe this got changed in the rendering software (mw-render) and not in the actual extension.
