I remember WebOb and WebHelpers each having a lot of changes and backward incompatibilities. Some of the things that have caused pain for me, were changes to the MultiDict object and character encodings.
Looking at the changelog... ( https://github.com/Pylons/webob/blob/master/docs/news.txt )... maybe it's from one of these 2 changes : 1.2a2 * To process requests that come in an encoding different from UTF-8, the request needs to be transcoded like this: ``req = req.decode('windows-1251')`` 1.2a1 * Remove UnicodeMultiDict class; the result of ``Request.GET`` and ``Request.POST`` is now just a plain ``MultiDict`` -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
