Catalyst::Upgrading - Instructions for upgrading to the latest Catalyst
+=head1 Upgrading to Catalyst 5.90100
+
+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 disappear 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:
+
+ $c->uri_for($action, 'foo#fragment');
+
+This behavior was never documented and would break if using the Unicode plugin, or when
+adding a query to the arguments:
+
+ $c->uri_for($action, 'foo#fragment', +{ a=>1, b=>2});
+
+would define a fragment like "#fragment?a=1&b=2".
+
+When we introduced UTF-8 encoding by default in Catalyst 5.9008x this side effect behavior
+was broken since we started encoding the '#' when it was part of the URI path.
+
+In version 5.90095 and 5.90096 we attempted to fix this, but all we managed to do was break
+people with URIs that included '#' as part of the path data, when it was not expected to
+be a fragment delimiter.
+
+In general L<Catalyst> prefers an explicit specification rather than relying on side effects
+or domain specific mini languages. As a result we are now defining how to set a fragment
+for a URI via ->uri_for:
+
+ $c->uri_for($action_or_path, \@captures_or_args, @args, \$query, \$fragment);
+
+If you are relying on the previous side effect behavior your URLs will now encode the '#'
+delimiter, which is going to be a breaking change for you. You need to alter your code
+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.
+
+B<NOTE> If you are using the string form of the first argument:
+
+ $c->uri_for('/foo/bar#baz')
+
+construction, we do not attempt to encode this and it will make a URL with a
+fragment of 'baz'.

+
+The method C<last_error> in L</Catalyst> was actually returning the first error. This has
+been fixed but there is a small chance it could be a breaking issue for you. If this gives
+you trouble changing to C<shift_errors> is the easiest workaround (although that does
+modify the error stack so if you are relying on that not being changed you should try something
+like @{$c->errors}[-1] instead. Since this method is relatively new and the cases when the
+error stack actually has more than one error in it, we feel the exposure is very low, but bug
+reports are very welcomed.

L<Catalyst::Utils> has a new method 'inject_component' which works the same as the method of
the same name in L<CatalystX::InjectComponent>. You should start converting any

+In order to give better backwards compatibility with the 5.90080+ UTF-8 changes
we've added several configuration options around control of how we try to decode
your URL keywords / query parameters.

the UTF-8 decoding globally using this configuration.

you are doing a lot of custom encoding of your URLs and not using UTF-8.
