=head2 Upgrading the HTTP Engine
If you were using L<Catalyst::Engine::HTTP::Prefork> then L<Starman>
is automatically loaded.
-XXX FIXME - note how to run Starman with different options.
+If you were customising your server script to pass opttions to the prefork engine,
+then this is no longer supported. The recommended route to implement this functionality

=head2 Upgrading the PSGI Engine
However, if you have an C<app.psgi> script, then you no longer
need to specify the PSGI engine. Instead, the L<Catalyst> application class

+now has a new method C<psgi_app> which returns a L<PSGI> compatible coderef
which you can wrap in middleware of your choice.
Catalyst will use the .psgi for your application if it is located in the C<home>
builder {
enable ... #enable your desired middleware
- MyCatalystApp->raw_psgi_app;
+ MyCatalystApp->psgi_app;
};
-And also rename C<< script/myapp.psgi >> to C<< myapp.psgi >>.
+In the simplest case:
-If you rename your .psgi file without these modifications, then any tests run via
+ MyCatalystApp->setup_engine('PSGI');
+ my $app = sub { MyCatalystApp->run(@_) }
+
+becomes
+
+ MyCatalystApp->setup_engine('PSGI');
+ my $app = MyCatalystApp->psgi_app(@_);
+
+B<NOT>:
+
+ my $app = sub { MyCatalystApp->psgi_app(@_) };
+ # If you make ^^ this mistake, your app won't work, and will confuse the hell out of you!
+
+You can now rename C<< script/myapp.psgi >> to C<< myapp.psgi >>, and the built-in
+Catalyst scripts, and your test suite will start using your .psgi file.
+
+B<NOTE:> If you rename your .psgi file without these modifications, then any tests run via
L<Catalyst::Test> will not be compatible with the new release, and will result in
the development server starting, rather than the expected test running.

=head2 Engines with unknown status
The following engines have untested or unknown compatibility. Reports are
highly welcomed:
- Catalyst::Engine::Embeddable - needs testing, should work?
- Catalyst::Engine::XMPP2
- Catalyst::Engine::SCGI
- Catalyst::Engine::Mojo
- Catalyst::Engine::Zeus - broken for ages
- Catalyst::Engine::JobQueue::POE - broken for ages
- Catalyst::Engine::Stomp - fixed

-XXX Should this be here or elsewhere?
+Tests should generally work the same in Catalyst 5.89, however there are some differences.
-=head2 Making an app.psgi file
+Previously, if using L<Catalyst::Test> and doing local requests (against a local server),

-=head2 Running with plackup?
+This behaviour has been removed, and now a 500 response will be returned to the test.

=head1 Upgrading to Catalyst 5.80
To be able to generate a linear @ISA, the list of superclasses for each
class must be resolvable using the C3 algorithm. Unfortunately, when
superclasses are being used as mixins (to add functionality used in your class),
