I made a mistake in the version history there. The point was that the
default wrapper didn't expose the Map methods in 2.3.x either, so most
users are not affected. Only I forgot about this SimpleMapModel VS
SimpleHash mess, which is AFAIK just a historical heritage, but fixing
it would break too much code... I guess. Anyway, thanks for reporting
this, I will fix it.
