What gives you that impression?

Or, more, what do you think the difference between http://0:3000/ and http://localhost:3000/ is?

As http://0:3000/ explicitly means 'port 3000 on any interface on this machine', whereas 'http://localhost:3000/' could be taken to mean 'port 3000 on'.

The Catalyst dev server has _always_ bound to any interface (unless you specifically tell it not to), and so there is no actual behaviour change here - saying 'http://localhost:3000/' was somewhat misleading, as the server _didn't_ only bind to localhost...

I would think the difference (to print a more correct statement of what the server is listening on) comes from 5.9 now using HTTP::Server::PSGI, rather than the traditional Catalyst specific test server..
