servant/servant-server/CHANGELOG.md

0.10
----

### Breaking changes

* `Handler` is now an abstract datatype. Migration hint: change `throwE` to `throwError`.
  ([#641](https://github.com/haskell-servant/servant/issues/641))

* Changed `HasServer` instances for `QueryParam` and `QueryParam` to throw 400
  when parsing fails
  ([#649](https://github.com/haskell-servant/servant/pull/649))

### Other changes

* Added `paramD` block to `Delayed`

* Add `err422` Unprocessable Entity
  ([#646](https://github.com/haskell-servant/servant/pull/646))

* Deprecate `serveDirectory` and introduce `serveDirectoryFileServer`,
  `serveDirectoryWebApp`, `serveDirectoryWebAppLookup`, `serveDirectoryEmbedded`
  and `serveDirectoryWith` which offer 4 default options and a more flexible
  one for serving static files.
  ([#658](https://github.com/haskell-servant/servant/pull/658))

* `DelayedIO` is an instance of `MonadResource`, allowing safe resource handling.
  ([#622](https://github.com/haskell-servant/servant/pull/622)
  , [#674](https://github.com/haskell-servant/servant/pull/674)
  , [#675](https://github.com/haskell-servant/servant/pull/675))

0.7.1
------

* Remove module `Servant.Server.Internal.Enter` (https://github.com/haskell-servant/servant/pull/478)
* Support GHC 8.0

0.7
---

* The `Router` type has been changed. Static router tables should now
  be properly shared between requests, drastically increasing the
  number of situations where servers will be able to route requests
  efficiently. Functions `layout` and `layoutWithContext` have been
  added to visualize the router layout for debugging purposes. Test
  cases for expected router layouts have been added.
* If an endpoint is discovered to have a non-matching "accept header",
  this is now a recoverable rather than a fatal failure, allowing
  different endpoints for the same route, but with different content
  types to be specified modularly.
* Export `throwError` from module `Servant`
* Add `Handler` type synonym

0.6.1
-----

* If servers use the `BasicAuth` combinator and receive requests with missing or
  invalid credentials, the resulting error responses (401 and 403) could be
  overwritten by subsequent alternative routes. Now `BasicAuth` uses `FailFatal`
  and the error responses can't be overwritten anymore.

0.6
---

* Query parameters that can't be parsed result in a `400` (was `404`).

0.5
---

* Add `Config` machinery (https://github.com/haskell-servant/servant/pull/327).
  This is a breaking change, as the signatures of both `route`, `serve` and the
  typeclass `HasServer` now take an additional parameter.
* Support for the `HttpVersion`, `IsSecure`, `RemoteHost` and `Vault` combinators
* Drop `EitherT` in favor of `ExceptT`
* Use `http-api-data` instead of `Servant.Common.Text`
* Remove matrix params.
* Remove `RouteMismatch`.
* Redefined constructors of `RouteResult`.
* Added `Delayed` and related functions (`addMethodCheck`, `addAcceptCheck`, `addBodyCheck`, `runDelayed`)
* Added support for Basic Authentication
* Add generalized authentication support via the `AuthServerData` type family and `AuthHandler` handler

0.4.1
-----
* Bump attoparsec upper bound to < 0.14
* Bump wai-app-static upper bound to < 3.2
* Bump either upper bound to < 4.5

0.4
---
* `Delete` now is like `Get`, `Post`, `Put`, and `Patch` and returns a response body
* Add a `RouteMismatch` constructor for arbitrary HTTP response codes (https://github.com/haskell-servant/servant-server/pull/22)
* Add support for the `Patch` combinator
* Support for `Accept`/`Content-type` headers and for the content-type aware combinators in *servant-0.4*
* Export `toApplication` from `Servant.Server` (https://github.com/haskell-servant/servant-server/pull/29)
* Support other Monads than just `EitherT (Int, String) IO` (https://github.com/haskell-servant/servant-server/pull/21)
* Make methods return status code 204 if they return () (https://github.com/haskell-servant/servant-server/issues/28)
* Add server support for response headers
* Use `ServantErr` instead of `(Int,String)` in `EitherT` handlers
* Add `errXXX` functions for HTTP errors with sensible default reason strings
* Add `enter` function for applying natural transformations to handlers

0.2.4
-----
* Added support for matrix parameters, see e.g. http://www.w3.org/DesignIssues/MatrixURIs.html
* Add support for serializing based on Accept header
  (https://github.com/haskell-servant/servant-server/issues/9)
* Ignore trailing slashes
  (https://github.com/haskell-servant/servant-server/issues/5)


0.2.3
-----

* Fix consuming request body issue
  (https://github.com/haskell-servant/servant/issues/3)
* Make code sample in Servant.Server complete
