+=head2 VERSION 5.90100
+
+Support for type constraints in Args and CaptureArgs has been improved.  You may
+now inherit from a base controller that declares type constraints and use roles
+that declare type constraints.  See L<Catalyst::RouteMatching> for more.
+
+You may now. also use a full type constraint namespace instead of inporting type
+constraints into your package namespace.
+
+We changed the way the middleware stash works so that it no longer localizes
+the PSGI env hashref.  This was done to fix bugs where people set PSGI ENV hash
+keys and found them to dissappear in certain cases.  It also means that now if
+a sub applications sets stash variables, that stash will now bubble up to the
+parent application.  This may be a breaking change for you since previous
+versions of this code did not allow that.  A workaround is to explicitly delete
+stash keys in your sub application before returning control to the parent
+application.
