+TurboGears-1.1.x is supposed to be compatible with TurboGears-1.0.x but we've
+run into several problems in the apps we've written in Fedora.  This file lists
+the known incompatibilities and how to fix them.
+
+IdentityWrapper has moved
+=========================
+
+turbogears.identity has been reorganized.  In particular,
+turbogears.identity.IdentityWrapper has been moved to
+turbogears.identity.base.IdentityWrapper

+Widget Change
+=============
+
+There's been changes to how widgets render.  In particular, when rendering a
+widget written in kid in a genshi template, the following code no longer

+
+You can use this instead::
+    ${ET(widget.display())}
