+Catalyst::Delta - Overview of changes between versions of Catalyst
-This is an overview of the user visible changes in 5.8
+=head1 DESCRIPTION
+
+This is an overview of the user-visible changes to Catalyst in version 5.8.
=head2 Deprecations
-::[MVC]:: style naming scheme has been deprecated and will warn
+Please see L<Catalyst::Upgrading> for a full description of how changes in the
+framework may affect your application.
+
+Below is a brief list of features which have been deprecated in this release:
+
+=over
+
+=item ::[MVC]:: style naming scheme has been deprecated and will warn
+
+=item NEXT is deprecated for all applications and components, use MRO::Compat
+
+=item Dispatcher methods which are an implementation detail made private, public versions now warn.
+
+=item MyApp->plugin method is deprecated, use L<Catalyst::Model::Adaptor> instead.
+
+=item __PACKAGE__->mk_accessors() is supported for backward compatibility only, use Moose attributes instead in new code.
+
+=item Use of Catalyst::Base now warns
+
+=back
+
+=head2 New features
+
+=head3 Dispatcher
+
+=over
+
+=item Fix forwarding to Catalyst::Action objects.
+
+=item Add the dispatch_type method
+
+=back
+
+=head3 Restarter
+
+The development server restarter has been improved to be compatible with
+immutable Moose classes, and also to optionally use
+L<B::Hooks::OP::Check::StashChange> to handle more complex application layouts
+correctly.
+
+=head3 $c->uri_for_action method.
+
+Give a private path to the Catalyst action you want to create a URI for.
+
+=head3 Logging
+
+Log levels have been made additive.
+
+=head3 L<Catalyst::Test>
+
+=over
+
+=item Change to use L<Sub::Exporter>.
+
+=item Support mocking multiple virtual hosts
+
+=item New methods like action_ok and action_redirect to write more compact tests
+
+=back
+
+=head3 Catalyst::Response
+
+=over
+
+=item *
+
+New print method which prints @data to the output stream, separated by $,.
+This lets you pass the response object to functions that want to write to an
+L<IO::Handle>.
+
+=item *
+
+Added code method as an alias for C<< $res->status >>
+
+=back
+
+=head2 Consequences of the Moose back end
+
+=over
+
+=item *
+
+Components are fully compatible with Moose, and all Moose features, such as
+method modifiers, attributes, roles, BUILD and BUILDARGS methods are fully
+supported and may be used in components and applications.
+
+=item *
+
+Many reusable extensions which would previously have been plugins or base
+classes are better implemented as Moose roles.
+
+=item *
+L<MooseX::MethodAttributes::Inheritable> is used to contain action
+attributes. This means that attributes are represented in the MOP, and
+decouples action creation from attributes.
- - Use Class::C3::Adopt::NEXT (rafl)
+=item *
-Catalyst 5.80 uses L<Algorithm::C3> method dispatch order. This is built into
-perl 5.10 (new pragma mro), and comes via L<Class::C3> for perl 5.8. This
-replaces L<NEXT> with L<Class::C3::Adopt::NEXT>, forcing all components to
-resolve methods using C3, rather than the unpredictable dispatch order of
-L<NEXT>. Please "use MRO::Compat" in both perl 5.8 and perl 5.10 to activate
-this feature.
-- Disallow writing to config after setup and disallow calling setup more
-than once (rafl)
+There is a reasonable API in Catalyst::Controller for working with
+and registering actions, allowing a controller sub-class to replace
+subroutine attributes for action declarations with an alternate
+syntax.
-=head2 Dispatcher
+=item *
-- visit and go now takes CaptureArgs
+Refactored capturing of $app from L<Catalyst::Controller> into
+L<Catalyst::Component::ApplicationAttribute> for easier reuse in other
+components.
- - Change the $c->visit and $c->go methods to optionally take
- CaptureArgs, making them useful to call ActionChains with (t0m)
+=item *
- - Fix forwarding to Catalyst::Action objects (Rafael Kitover).
+Your application class is forced to become immutable at the end of compilation.
-=head2 restarter
+=back
-- Non-naive implementation of making mutable on restart using
- B::Hooks::OP::Check::StashChange if installed (t0m)
- For a restart the immutable Moose-objects need to turn back to mutable.
- With L<B::Hooks::OP::Check::StashChange> installed this will be done.
+=head2 Bug fixes
-= head2 $c->uri_for_action method. (hdp)
+=over
-A private path to the Catalyst action you want to create a URI for.
-This is a shortcut for calling C<< $c->dispatcher->get_action_by_path($path) >>
-and passing the resulting C<$action> and the remaining arguments to
-C<< $c->uri_for >>.
+=item *
+Don't ignore SIGCHLD while handling requests with the development server, so that
+system() and other ways of creating child processes work as expected.
-=head2 Logging
+=item *
- - Make log levels additive, and add documentation and tests
- for the setup_log method, which previously had none.
- Sewn together by t0m from two patches provided by David E. Wheeler
+Fixes for FastCGI when used with IIS 6.0
-=head2 Consequences of the Moose backend
+=item *
- - Use MooseX::MethodAttributes::Inheritable to contain action
- attributes. This means that attributes are now represented in the MOP,
- allowing method modifiers on actions to work as expected. (rafl)
- - Provide a reasonable API in Catalyst::Controller for working with
- and registering actions, allowing a controller sub-class to replace
- subroutine attributes for action declerations with an alternate
- syntax. (rafl/hdp)
- - Refactor capturing of $app from Catalyst::Controller into
- Catalyst::Component::ApplicationAttribute for easier reuse in other
- components (Florian Ragwitz)
- - Make MyApp immutable at the end of the scope after the setup
- method is called, fixing issues with plugins which have their
- own new methods by inlining a constructor on MyApp (t0m)
- - Instantiate correct sub-class of Moose::Meta::Class for non-Moose
- components where Catalyst forces the creation of a metaclass instance.
-
-=head2 Test Suite
+Fix a bug in uri_for which could cause it to generate paths with multiple
+slashes in them.
- - Change Catalyst::Test to use Sub::Exporter (Florian Ragwitz).
- - Port to Moose
- - Support mocking virtualhosts in test suite ()
- - Add methods like action_ok and action_redirect to write
- more compact tests
+=item *
-=head2 Catalyst::Response->print()
+Fix a bug in Catalyst::Stats, stopping garbage being inserted into
+the stats if a user calls begin => but no end
-Prints @data to the output stream, separated by $,. This lets you pass
-the response object to functions that want to write to an L<IO::Handle>.
