# Changelog

## v0.4.0 (2014-08-30)

* Enhancements
  * Controllers are now Plugs and can be plugged as a "second layer" plug stack from the Router plug stack
  * Elixir Logger Integration - Improved request logger, durations, params, etc
  * Custom 404/500 page handling, [details](https://github.com/phoenixframework/phoenix/blob/0b6bdffab45fc46bc1455860f2d3971d0224eeb5/README.md#custom-not-found-and-error-pages)
  * Ability to halt Plug stacks with Plug 0.7.0 `halt/1`
  * Internationalization support
  * Flash messages for one-time message support across redirects
  * New `Template.Engine` behaviour for third-party template engines. See [PhoenixHaml](https://github.com/chrismccord/phoenix_haml) for haml support via Calliope.
  * `render/2` can be explicitly plugged for automatic rendering of actions based on action name
  * Add assign_layout/2 and assign_status/2
  * Assign API for Sockets allows ephemeral state to be stored on the multiplexed socket, similar to conn assigns
  * Add `proxy_port` Router config option for deployments where public facing port differs from local port
  * Add nested generated `Helpers` module to Routers for easy imports of named route helpers, ie `import MyApp.Router.Helpers`


* Bug fixes
  * Various bug fixes and improvements

* Backwards incompatible changes
  * ExConf Configuration has been replaced by Mix Config
  * Directory and naming conventions have changed. A `web/` directory now lives at root of the project and holds routers, controllers, channels, views & templates, where all `web/` files are recompiled by the code reloader during development. Modules that cannot be simply recompiled in process are placed in lib as normal and require a server restart to take effect. Follow [this guide](https://gist.github.com/dgoldie/2fdc90fe09ecdddb78f4) for upgrade steps from 0.3.x.
  * Naming conventions now use singular form for module names, directory names, and named route helpers
  * Named route helpers have been reworked to use single function name with pattern matched arguments. See the [readme  examples](https://github.com/phoenixframework/phoenix/blob/0b6bdffab45fc46bc1455860f2d3971d0224eeb5/README.md#resources)
  * `layout: nil` render option has been replaced by `assign_layout(conn, :none)`
  * `Plugs.JSON` now adds parsed params under "_json" key when the JSON object is an array
