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).
2022-02-01 12:22:41 +01:00
- 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.
2022-01-31 15:13:47 +01:00
- 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 )).
2021-06-23 23:38:46 +02:00
0.18.3
------
### Significant changes
- Add response header support to UVerb (#1420)
### Other changes
- Support GHC-9.0.1.
- Bump `bytestring` , `hspec` and `base64-bytestring` dependencies.
2020-11-22 15:51:32 +01:00
0.18.2
------
### Significant changes
- Support `Fragment` combinator.
2020-11-04 13:28:20 +01:00
0.18.1
------
### Significant changes
- Union verbs
### Other changes
- Bump "tested-with" ghc versions
- Allow newer dependencies
2020-07-31 20:19:07 +02:00
0.18
----
### Significant changes
- Support for ghc8.8 (#1318, #1326 , #1327 )
- Configurable error messages for automatic errors thrown by servant,
like "no route" or "could not parse json body" (#1312, #1326 , #1327 )
2020-01-23 12:43:19 +01:00
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-server* use queryString to parse QueryParam, QueryParams and QueryFlag [#1249 ](https://github.com/haskell-servant/servant/pull/1249 ) [#1262 ](https://github.com/haskell-servant/servant/pull/1262 )
Some APIs need query parameters rewriting, e.g. in order to support
for multiple casing (camel, snake, etc) or something to that effect.
2020-06-06 06:43:51 +02:00
This could be easily achieved by using WAI Middleware and modifying
2020-01-23 12:43:19 +01:00
request's `Query` . But QueryParam, QueryParams and QueryFlag use
`rawQueryString` . By using `queryString` rather then `rawQueryString`
we can enable such rewritings.
- *servant* *servant-server* Make packages `build-type: Simple` [#1263 ](https://github.com/haskell-servant/servant/pull/1263 )
We used `build-type: Custom` , but it's problematic e.g.
for cross-compiling. The benefit is small, as the doctests
2020-06-06 06:43:51 +02:00
can be run other ways too (though not so conveniently).
2020-01-23 12:43:19 +01:00
2019-08-03 15:19:37 +02:00
0.16.2
------
* `singleton-bool-0.1.5` (`SBool` is re-exported)
- Add `discreteBool :: Dec (a :~: b)` (GHC-7.8+)
- Add `Show` , `Eq` , `Ord` `SBool b` instances.
* dependencies update
0.16.1
------
* Use `http-api-data-0.4.1` (a part of its API is re-exported)
[#1181 ](https://github.com/haskell-servant/servant/pull/1181 )
2019-02-21 09:59:45 +01:00
0.16
----
- Rename `ServantError` to `ClientError` , `ServantErr` to `ServerError`
2019-03-06 18:30:41 +01:00
[#1131 ](https://github.com/haskell-servant/servant/pull/1131 )
2019-02-21 09:59:45 +01:00
- *servant-server* Reorder HTTP failure code priorities
[#1103 ](https://github.com/haskell-servant/servant/pull/1103 )
2019-02-27 12:04:33 +01:00
- *servant-server* Re-organise internal modules
[#1139 ](https://github.com/haskell-servant/servant/pull/1139 )
2019-02-21 09:59:45 +01:00
- Allow `network-3.0`
2019-03-06 18:30:41 +01:00
[#1107 ](https://github.com/haskell-servant/servant/pull/1107 )
2019-02-21 09:59:45 +01:00
2018-11-12 21:04:29 +01:00
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.
- 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* NewlineFraming encodes newline after each element (i.e last)
[#1079 ](https://github.com/haskell-servant/servant/pull/1079 )
[#1011 ](https://github.com/haskell-servant/servant/issues/1011 )
- *servant* Add `lookupResponseHeader :: ... => Headers headers r -> ResponseHeader h a`
[#1064 ](https://github.com/haskell-servant/servant/pull/1064 )
- *servant-server* Add `MonadMask Handler`
[#1068 ](https://github.com/haskell-servant/servant/pull/1068 )
- *servant* Export `GetHeaders'`
[#1052 ](https://github.com/haskell-servant/servant/pull/1052 )
- *servant* Add `Bitraversable` and other `Bi-` instances for `:<|>`
[#1032 ](https://github.com/haskell-servant/servant/pull/1032 )
- *servant* Add `PutCreated` method type alias
[#1024 ](https://github.com/haskell-servant/servant/pull/1024 )
- *servant* Add `ToSourceIO (NonEmpty a)` instance
[#988 ](https://github.com/haskell-servant/servant/pull/988 )
2018-07-04 21:59:43 +02:00
0.14.1
------
- Merge in `servant-generic` (by [Patrick Chilton ](https://github.com/chpatrick ))
into `servant` (`Servant.API.Generic`),
`servant-client-code` (`Servant.Client.Generic`)
and `servant-server` (`Servant.Server.Generic`).
- *servant-server* Deprecate `Servant.Utils.StaticUtils` , use `Servant.Server.StaticUtils` .
2018-06-18 16:12:35 +02:00
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-server* File serving in polymorphic monad.
i.e. Generalised types of `serveDirectoryFileServer` etc functions in
`Servant.Utils.StaticFiles`
([#953](https://github.com/haskell-servant/servant/pull/953))
- *servant-server* `ReqBody` content type check is recoverable.
This allows writing APIs like:
```haskell
ReqBody '[JSON] Int :> Post '[PlainText] Int
:< |> ReqBody '[PlainText] Int :> Post '[PlainText] Int
```
which is useful when handlers are subtly different,
for example may do less work.

2017-01-16 10:44:25 +01:00
2017-01-09 11:04:08 +01:00
* Deprecate `serveDirectory` and introduce `serveDirectoryFileServer` ,
`serveDirectoryWebApp` , `serveDirectoryWebAppLookup` , `serveDirectoryEmbedded`
and `serveDirectoryWith` which offer 4 default options and a more flexible
one for serving static files.
2017-01-30 07:45:58 +01:00
([#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 ))
2016-05-10 16:16:37 +02:00
0.7.1
------
* Remove module `Servant.Server.Internal.Enter` (https://github.com/haskell-servant/servant/pull/478)
2016-05-10 22:45:06 +02:00
* Support GHC 8.0
2016-05-10 16:16:37 +02:00

0.7
---
2016-04-09 15:42:57 +02:00
* 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
2016-04-07 13:45:15 +02:00
cases for expected router layouts have been added.
2016-04-12 10:35:07 +02:00
* 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.
2016-04-11 20:19:18 +02:00
* Export `throwError` from module `Servant`
2016-04-12 07:58:00 +02:00
* Add `Handler` type synonym
2016-04-07 13:45:15 +02:00
2016-04-08 08:49:51 +02:00
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.

2016-03-27 11:05:59 +02:00

2015-06-23 10:34:20 +02:00
2016-01-18 22:34:56 +01:00
* Add `Config` machinery (https://github.com/haskell-servant/servant/pull/327).
2016-01-21 18:04:00 +01:00
This is a breaking change, as the signatures of both `route` , `serve` and the
typeclass `HasServer` now take an additional parameter.
2015-06-23 10:34:20 +02:00
* Support for the `HttpVersion` , `IsSecure` , `RemoteHost` and `Vault` combinators
2015-09-12 14:11:24 +02:00
* Drop `EitherT` in favor of `ExceptT`

* Remove `RouteMismatch` .
* Redefined constructors of `RouteResult` .
2015-10-13 20:29:14 +02:00
* Added `Delayed` and related functions (`addMethodCheck`, `addAcceptCheck` , `addBodyCheck` , `runDelayed` )
2016-02-17 20:25:34 +01:00
* Added support for Basic Authentication
2016-02-17 21:57:04 +01:00
