+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.

In older versions of Catalyst one could construct a L<URI> with a fragment (such as
https://localhost/foo/bar#fragment) by using a '#' in the path or final argument, for
example:
- $c->uri_for('/mypath#fragment');
-
-or:
-
$c->uri_for($action, 'foo#fragment');
This behavior was never documented and would break if using the Unicode plugin, or when
to match the new specification or modify uri_for for your local case. Patches to solve
this are very welcomed, as long as they don't break existing test cases.
