## v0.6.0 (2014-11-22)

See the [`0.5.x` to `0.6.0` upgrade instructions](https://gist.github.com/chrismccord/e774e6ab5220e6505a03) for upgrading your
existing applications.

* Enhancements
  * [Controller] Support `put_view/2` to configure which view to use
when rendering in the controller
  * [Controller] Support templates as an atom in
`Phoenix.Controller.render/3` as a way to explicitly render templates
based on the request format
  * [Controller] Split paths from external urls in `redirect/2`
  * [Controller] `json/2` automatically encodes the data to JSON by
using the registered `:format_encoders`
  * [Controller] `html/2`, `json/2`, `text/2`, `redirect/2` and
`render/3` now halt automatically
  * [Controller] Add `accepts/2` for content negotiation
  * [Controller] Add `put_layout_formats/2` and `layout_formats/1` to
configure and read which formats have a layout when rendering
  * [View] Assigns are always guaranteed to be maps
  * [View] Add support to `format_encoders` that automatically encodes
rendered templates. This means a "user.json" template only needs to
return a map (or any structure encodable to JSON) and it will be
automatically encoded to JSON by Phoenix
  * [View] Add a .exs template engine
  * [Channel] Add a `Transport` contract for custom Channel backends
  * [Channel] Add a `LongPoller` transport with automatic LP fallback
in `phoenix.js`
  * [phoenix.js] Add long-polling support with automatic LP fallback
for older browsers

* Deprecations
  * [Controller] `html/3`, `json/3`, `text/3` and `redirect/3` were
deprecated in favor of using `put_status/2`
  * [Controller] `redirect(conn, url)` was deprecated in favor of
`redirect(conn, to: url)`

* Backwards incompatible changes
  * [Controller] Passing a string to render without format in the
controller, as in `render(conn, "show")` no longer works. You should
either make the format explicit `render(conn, "show.html")` or use an
atom `render(conn, :show)` to dynamically render based on the format
  * [View] Using `:within` was renamed in favor of `:layout` for
rendering with layouts
  * [View] Your application should now directly use Phoenix.View in
its main view and specify further configuration in the `using(...)`
section
  * [View] Template engines now should implement compile and simply
return the quoted expression of the function body instead of the
quoted expression of the render function
  * [Router] `PUT` route generation for the `:update` action has been
dropped in favor of `PATCH`, but `PUT` still matches requests to maintain compatibility with proxies.
  * [Router] Router no longer defines default :browser and :api
pipelines

* Bug fixes
  * [Router] Generate correct route for helper path on root

## v0.5.0

* Enhancements
  * [Router] Named helpers are now automatically generated for every
route based on the controller name
  * [Router] Named helpers have been optimized to do as little work as
possible at runtime
  * [Router] Support multiple pipelines at the router level
  * [Channels] The `phoenix.js` channel client now sends a
configurable heartbeat every 30s to maintain connections

* Deprecations
  * [Controller] `assign_private` is deprecated in favor of
`put_private`
  * [Controller] `assign_status` is deprecated in favor of
`put_status`

* Backwards incompatible changes
  * [Controller] Remove default, injected aliases: `Flash`, `JSON`
  * [Controller] Controllers now require `plug :action` to be
explicitly invoked
  * [Router] `*path` identifiers in routers are now returned as a list
  * [Router] Named helpers are now defined in a explicit module nested
to your router. For example, if your router is named `MyApp.Router`,
the named helpers will be available at `MyApp.Router.Helpers`
  * [Router] `session_secret` configuration is deprecated in favor of
`secret_key_base`
  * [Router] Plugs can now only be defined inside pipelines. All
routers now need to explicitly declare which pipeline they want to use
  * [Router] Router configuration was revamped, static configuration
has been moved into `:static`, session configuration into `:session`,
parsers configuration into `:parsers`, the http server configuration
has been moved into `:http`, the https configuration into `:https` and
the URI information for generating URIs into `:uri`
  * [CodeReloaer] Code reloading now requires the `:phoenix` compiler
to be added to the list of compilers in your `mix.exs` project config,
ie: `compilers: [:phoenix] ++ Mix.compilers`. Additionally, the
`Phoenix.CodeReloader.reload!` invocation should be removed from your
`test_helper.exs` for applications generated on `0.4.x`.
  * [Topic] `Phoenix.Topic` has been renamed to `Phoenix.PubSub`. If you were calling into the topic layer directly, update your module references.

"second layer" plug stack from the Router plug stack
  * [Controller] Elixir Logger Integration - Improved request logger,
durations, params, etc
  * [Controller] Custom 404/500 page handling,
[details](https://github.com/phoenixframework/phoenix/blob/0b6bdffab45fc46bc1455860f2d3971d0224eeb5/README.md#custom-not-found-and-error-pages)

support via Calliope.
  * `render/2` can be explicitly plugged for automatic rendering of
actions based on action name
  * [Channel] Assign API for Sockets allows ephemeral state to be
stored on the multiplexed socket, similar to conn assigns
  * [Config] Add `proxy_port` Router config option for deployments
where public facing port differs from local port
  * [Router] 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
  * [Config] 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
  * [Router] 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)
  * [Controller] `layout: nil` render option has been replaced by
`assign_layout(conn, :none)`
  * [Plugs] `Plugs.JSON` now adds parsed params under "_json" key when
the JSON object is an array

## v0.3.0 (2014-06-30)

* Enhancements
  * Add Precompiled EEx Templating Engine and View layer
  * Add JSON Plug parser

query string params

* Bug fixes
  * Auto template compilation has been fixed for Elixir 0.14.2
`@external_resource` changes

* Backwards incompatible changes
  * Controller action arity has changed. All actions now receive the
Plug conn and params as arguments, ie `def show(conn, %{"id" => id})`
  * Channel and Topic `reply` and `broadcast` functions now require a
map instead of an arbitrary dict
