Changelog for v1.5

See the upgrade guides to bring your Phoenix 1.4.x apps up to speed

Phoenix.PubSub 2.0 released

Phoenix.PubSub 2.0 has been released with a more flexible and powerful fastlane mechanism. We use this opportunity to also move Phoenix.PubSub out of the endpoint and explicitly into your supervision tree. To update, you will need to remove or update the {:phoenix_pubsub, "~> 1.x"} entry in your mix.exs to at least "2.0".

Then once you start an application, you will get a warning about the :pubsub key in your endpoint being deprecated. Follow the steps in the warning and you are good to go!

Guides revamped

Phoenix built-in guides have been restructured and revamped, providing a better navigation structure and more content.
