0.19
----
### Significant changes
- Drop support for GHC < 8.6.
- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
related to hash collisions.
- Add `NamedRoutes` combinator, making support for records first-class in Servant
([#1388](https://github.com/haskell-servant/servant/pull/1388)).
- Add custom type errors for partially applied combinators
([#1289](https://github.com/haskell-servant/servant/pull/1289),
[#1486](https://github.com/haskell-servant/servant/pull/1486)).
- *servant-client* / *servant-client-core* / *servant-http-streams*: Fix
erroneous behavior, where only 2XX status codes would be considered
successful, irrelevant of the status parameter specified by the verb
combinator. ([#1469](https://github.com/haskell-servant/servant/pull/1469))
- *servant-client* / *servant-client-core*: Fix `Show` instance for
`Servant.Client.Core.Request`.
- *servant-client* / *servant-client-core*: Allow passing arbitrary binary data
in Query parameters.
([#1432](https://github.com/haskell-servant/servant/pull/1432)).

- Bump `bytestring`, `hspec`, `http-client` and `QuickCheck` dependencies.
0.18.2
------

0.18
----
### Significant changes
- Support for ghc8.8 (#1318, #1326, #1327)
0.17
----
### Significant changes
- Add NoContentVerb [#1028](https://github.com/haskell-servant/servant/issues/1028) [#1219](https://github.com/haskell-servant/servant/pull/1219) [#1228](https://github.com/haskell-servant/servant/pull/1228)
The `NoContent` API endpoints should now use `NoContentVerb` combinator.
The API type changes are usually of the kind
```diff
- :<|> PostNoContent '[JSON] NoContent
+ :<|> PostNoContent
```
i.e. one doesn't need to specify the content-type anymore. There is no content.
- `Capture` can be `Lenient` [#1155](https://github.com/haskell-servant/servant/issues/1155) [#1156](https://github.com/haskell-servant/servant/pull/1156)
You can specify a lenient capture as
```haskell
:<|> "capture-lenient" :> Capture' '[Lenient] "foo" Int :> GET
```
which will make the capture always succeed. Handlers will be of the
type `Either String CapturedType`, where `Left err` represents
the possible parse failure.
- *servant-client* Added a function to create Client.Request in ClientEnv [#1213](https://github.com/haskell-servant/servant/pull/1213) [#1255](https://github.com/haskell-servant/servant/pull/1255)
The new member `makeClientRequest` of `ClientEnv` is used to create
`http-client` `Request` from `servant-client-core` `Request`.
This functionality can be used for example to set
dynamic timeouts for each request.
### Other changes
- *servant-client* *servant-client-core* *servant-http-streams* Fix Verb with headers checking content type differently [#1200](https://github.com/haskell-servant/servant/issues/1200) [#1204](https://github.com/haskell-servant/servant/pull/1204)
For `Verb`s with response `Headers`, the implementation didn't check
for the content-type of the response. Now it does.
- *servant-client* *servant-http-streams* `HasClient` instance for `Stream` with `Headers` [#1170](https://github.com/haskell-servant/servant/issues/1170) [#1197](https://github.com/haskell-servant/servant/pull/1197)
- *servant-client* Redact the authorization header in Show and exceptions [#1238](https://github.com/haskell-servant/servant/pull/1238)
0.16.0.1
--------
- Allow `base-compat-0.11`
0.16
----
- Rename `ServantError` to `ClientError`, `ServantErr` to `ServerError`
[#1131](https://github.com/haskell-servant/servant/pull/1131)
- *servant-client-core* Rearrange modules. No more `Internal` modules, whole
API is versioned.
[#1130](https://github.com/haskell-servant/servant/pull/1130)
- *servant-client-core* `RequestBody` is now
```haskell
= RequestBodyLBS LBS.ByteString
| RequestBodyBS BS.ByteString
| RequestBodySource (SourceIO LBS.ByteString)
```
i.e. no more replicates `http-client`s API.
[#1117](https://github.com/haskell-servant/servant/pull/1117)
- *servant-client-core* Keep structured exceptions in `ConnectionError`
constructor of `ClientError`
[#1115](https://github.com/haskell-servant/servant/pull/1115)
```diff
-| ConnectionError Text
+| ConnectionError SomeException
```
- *servant-client-core* Preserve failing request in `FailureResponse`
constructor of `ClientError`
[#1114](https://github.com/haskell-servant/servant/pull/1114)
```diff
-FailureResponse Response
+-- | The server returned an error response including the
+-- failing request. 'requestPath' includes the 'BaseUrl' and the
+-- path of the request.
+FailureResponse (RequestF () (BaseUrl, BS.ByteString)) Response
```
- *servant-client* Fix (implement) `StreamBody` instance
[#1110](https://github.com/haskell-servant/servant/pull/1110)
- *servant-client* Update CookieJar with intermediate request/responses (redirects)
[#1104](https://github.com/haskell-servant/servant/pull/1104)
0.15
----
- Streaming refactoring.
[#991](https://github.com/haskell-servant/servant/pull/991)
[#1076](https://github.com/haskell-servant/servant/pull/1076)
[#1077](https://github.com/haskell-servant/servant/pull/1077)
The streaming functionality (`Servant.API.Stream`) is refactored to use
`servant`'s own `SourceIO` type (see `Servant.Types.SourceT` documentation),
which replaces both `StreamGenerator` and `ResultStream` types.
New conversion type-classes are `ToSourceIO` and `FromSourceIO`
(replacing `ToStreamGenerator` and `BuildFromStream`).
There are instances for *conduit*, *pipes* and *machines* in new packages:
[servant-conduit](https://hackage.haskell.org/package/servant-conduit)
[servant-pipes](https://hackage.haskell.org/package/servant-pipes) and
[servant-machines](https://hackage.haskell.org/package/servant-machines)
respectively.
Writing new framing strategies is simpler. Check existing strategies for examples.
This change shouldn't affect you, if you don't use streaming endpoints.
- *servant-client* Separate streaming client.
[#1066](https://github.com/haskell-servant/servant/pull/1066)
We now have two `http-client` based clients,
in `Servant.Client` and `Servant.Client.Streaming`.
Their API is the same, except for
- `Servant.Client` **cannot** request `Stream` endpoints.
- `Servant.Client` is *run* by direct
`runClientM :: ClientM a -> ClientEnv -> IO (Either ServantError a)`
- `Servant.Client.Streaming` **can** request `Stream` endpoints.
- `Servant.Client.Streaming` is *used* by CPSised
`withClientM :: ClientM a -> ClientEnv -> (Either ServantError a -> IO b) -> IO b`
To access `Stream` endpoints use `Servant.Client.Streaming` with
`withClientM`; otherwise you can continue using `Servant.Client` with `runClientM`.
You can use both too, `ClientEnv` and `BaseUrl` types are same for both.
**Note:** `Servant.Client.Streaming` doesn't *stream* non-`Stream` endpoints.
Requesting ordinary `Verb` endpoints (e.g. `Get`) will block until
the whole response is received.
There is `Servant.Client.Streaming.runClientM` function, but it has
restricted type. `NFData a` constraint prevents using it with
`SourceT`, `Conduit` etc. response types.
```haskell
runClientM :: NFData a => ClientM a -> ClientEnv -> IO (Either ServantError a)
```
This change shouldn't affect you, if you don't use streaming endpoints.
- Drop support for GHC older than 8.0
[#1008](https://github.com/haskell-servant/servant/pull/1008)
[#1009](https://github.com/haskell-servant/servant/pull/1009)
- *servant-client-core* Add `NFData (GenResponse a)` and `NFData ServantError` instances.
[#1076](https://github.com/haskell-servant/servant/pull/1076)
*servant-client-core* Add `aeson` and `Lift BaseUrl` instances
[#1037](https://github.com/haskell-servant/servant/pull/1037)
0.14
----
- `Stream` takes a status code argument
```diff
-Stream method framing ctype a
+Stream method status framing ctype a
```
([#966](https://github.com/haskell-servant/servant/pull/966)
[#972](https://github.com/haskell-servant/servant/pull/972))
- `ToStreamGenerator` definition changed, so it's possible to write an instance
for conduits.
```diff
-class ToStreamGenerator f a where
- toStreamGenerator :: f a -> StreamGenerator a
+class ToStreamGenerator a b | a -> b where
+ toStreamGenerator :: a -> StreamGenerator b
```
([#959](https://github.com/haskell-servant/servant/pull/959))
- Added `NoFraming` streaming strategy
([#959](https://github.com/haskell-servant/servant/pull/959))
- *servant-client-core* Add `hoistClient` to `HasClient`.
Just like `hoistServer` allows us to change the monad in which request handlers
of a web application live, we also have `hoistClient` for changing the monad
in which *client functions* live.
Read [tutorial section for more information](https://docs.servant.dev/en/release-0.14/tutorial/Client.html#changing-the-monad-the-client-functions-live-in).
([#936](https://github.com/haskell-servant/servant/pull/936))
- *servant-client* Add more constructors to `RequestBody`, including
`RequestBodyStream`.
*Note:* we are looking for http-library agnostic API,
so the might change again soon.
Tell us which constructors are useful for you!
([#913](https://github.com/haskell-servant/servant/pull/913))

0.9.1.1
-------
* Add MonadThrow and MonadCatch instances for ClientM
