50−This change is achieved by the introduction of a CaptureHint type, which is passed as an extra argument to the CaptureRouter and CaptureAllRouter constructors for the Router' type.
51−CaptureHint values are then used in routerLayout, to display the name and type of captured values, instead of just `<capture>` previously.
52−
53−N.B.:
54−Because the choice smart constructor for routers can aggregate Capture combinators with different capture hints, the Capture*Router constructors actually take a list of CaptureHint, instead of a single one.
55−
56−This PR also introduces Spec tests for the routerLayout function.
57−
58−Warning:
59−This change is potentially breaking, because it adds the constraint `Typeable a` to all types that are to be captured. Because all types are typeable since GHC 7.10, this is not as bad as it sounds ; it only break expressions where `a` is quantified in an expression with `Capture a`.
60−In those cases, the fix is easy: it suffices to add `Typeable a` to the left-hand side of the quantification constraint.
61−
62−For instance, the following code will no longer compile:
63−```haskell
64−type MyAPI a = Capture "foo" a :> Get '[JSON] ()
65−
66−myServer :: forall a. Server (MyAPI a)

77−## Error formatters
78−
79−`servant-server` provides an `ErrorFormatter` type to specify how the error message will be
80−formatted. A formatter is just a function accepting three parameters:
81−
82−- `TypeRep` from `Data.Typeable`: this is a runtime representation of the type of the combinator
83− (like `Capture` or `ReqBody`) that generated the error. It can be used to display its name (with
84− `show`) or even dynamically dispatch on the combinator type. See the docs for `Data.Typeable` and
85− `Type.Reflection` modules.
86−- `Request`: full information for the request that led to the error.
87−- `String`: specific error message from the combinator.
88−
89−The formatter is expected to produce a `ServerError` which will be returned from the handler.
90−
91−Additionally, there is `NotFoundErrorFormatter`, which accepts only `Request` and can customize the
92−error in case when no route can be matched (HTTP 404).
93−
94−Let's make two formatters. First one will wrap our error in a JSON:
95−
96−```json
97−{
98− "error": "ERROR MESSAGE",
99− "combinator": "NAME OF THE COMBINATOR"
100−}
101−```
102−
103−Additionally, this formatter will examine the `Accept` header of the request and generate JSON
104−message only if client can accept it.
105−
106−```haskell
107−customFormatter :: ErrorFormatter
108−customFormatter tr req err =
109− let
110− -- aeson Value which will be sent to the client
111− value = object ["combinator" .= show tr, "error" .= err]
112− -- Accept header of the request
113− accH = getAcceptHeader req
114− in
115− -- handleAcceptH is Servant's function that checks whether the client can accept a
116− -- certain message type.
117− -- In this case we call it with "Proxy '[JSON]" argument, meaning that we want to return a JSON.
118− case handleAcceptH (Proxy :: Proxy '[JSON]) accH value of
119− -- If client can't handle JSON, we just return the body the old way
120− Nothing -> err400 { errBody = cs err }
121− -- Otherwise, we return the JSON formatted body and set the "Content-Type" header.
122− Just (ctypeH, body) -> err400
123− { errBody = body
124− , errHeaders = [("Content-Type", cs ctypeH)]
125− }
126−
127−notFoundFormatter :: NotFoundErrorFormatter
128−notFoundFormatter req =
129− err404 { errBody = cs $ "Not found path: " <> rawPathInfo req }
130−```
131−
132−If you don't need to react to the `Accept` header, you can just unconditionally return the JSON like
133−this (with `encode` from `Data.Aeson`):
134−
135−```
136−err400
137− { errBody = encode body
138− , errHeaders = [("Content-Type", "application/json")]
139− }
140−```
141−
142−## Passing formatters to Servant
143−
144−Servant uses the Context to configure formatters. You only need to add a value of type
145−`ErrorFormatters` to your context. This is a record with the following fields:
146−
147−- `bodyParserErrorFormatter :: ErrorFormatter`
148−- `urlParseErrorFormatter :: ErrorFormatter`
149−- `headerParseErrorFormatter :: ErrorFormatter`
150−- `notFoundErrorFormatter :: NotFoundErrorFormatter`
151−
152−Default formatters are exported as `defaultErrorFormatters`, so you can use record update syntax to
153−set the only ones you need:
154−
155−```haskell
156−customFormatters :: ErrorFormatters
157−customFormatters = defaultErrorFormatters
158− { bodyParserErrorFormatter = customFormatter
159− , notFoundErrorFormatter = notFoundFormatter
160− }
161−```
162−
163−And at last, use `serveWithContext` to run your server as usual:
164−
165−```haskell
166−app :: Application
167−app = serveWithContext testApi (customFormatters :. EmptyContext) server
168−
169−main :: IO ()
170−main = run 8000 app
171−```
172−
173−Now if we try to request something with a wrong body, we will get a nice error:
174−
175−```
176−$ http -j POST localhost:8000/greet 'foo=bar'
177−HTTP/1.1 400 Bad Request

188−2017](https://github.com/haskell-servant/servant/issues/841) that was
189−resolved by the introduction of `UVerb`, with a long discussion on

192−[servant-checked-exceptions](https://hackage.haskell.org/package/servant-checked-exceptions)
193−is a good solution to the problem, but it restricts the user to JSON
194−and a very specific envelop encoding for the union type, which is
195−often not acceptable. (One good reason for this design choice is that
196−it makes writing clients easier, where you need to get to the union
197−type from one representative, and you don't want to run several
198−parsers in the hope that the ones that should will always error out so
199−you can try until the right one returns a value.)

201−[servant-exceptions](https://github.com/ch1bo/servant-exceptions) is
202−another shot at at the problem. It is inspired by
203−servant-checked-exceptions, so it may be worth taking a closer look.
204−The README claims that
205−[cardano-sl](https://github.com/input-output-hk/cardano-sl) also has
206−some code for generalized error handling.

209−code from
210−[world-peace](https://hackage.haskell.org/package/world-peace), but

55**servant** however has a way to inspect APIs, because APIs are just Haskell types and (GHC) Haskell lets us do quite a few things with types. In the same way that we look at an API type to deduce the types the handlers should have, we can inspect the structure of the API to *derive* Haskell functions that take one argument for each occurrence of `Capture`, `ReqBody`, `QueryParam`

238−### XSRF and the frontend
239−
240−XSRF protection works by requiring that there be a header of the same value as
241−a distinguished cookie that is set by the server on each request. What the
242−cookie and header name are can be configured (see `xsrfCookieName` and
243−`xsrfHeaderName` in `CookieSettings`), but by default they are "XSRF-TOKEN" and
244−"X-XSRF-TOKEN". This means that, if your client is a browser and you're using
245−cookies, Javascript on the client must set the header of each request by
246−reading the cookie. For jQuery, and with the default values, that might be:
247−
248−~~~ javascript
249−
250−var token = (function() {
251− r = document.cookie.match(new RegExp('XSRF-TOKEN=([^;]+)'))
252− if (r) return r[1];
253−})();
254−
255−
256−$.ajaxPrefilter(function(opts, origOpts, xhr) {
257− xhr.setRequestHeader('X-XSRF-TOKEN', token);
258− }
259−
260−~~~
261−
262−I *believe* nothing at all needs to be done if you're using Angular's `$http`
263−directive, but I haven't tested this.
264−
265−XSRF protection can be disabled just for `GET` requests by setting
266−`xsrfExcludeGet = False`. You might want this if you're relying on the browser
267−to navigate between pages that require cookie authentication.
268−
269−XSRF protection can be completely disabled by setting `cookieXsrfSetting =
270−Nothing` in `CookieSettings`. This is not recommended! If your cookie
271−authenticated web application runs any javascript, it's recommended to send the
272−XSRF header. However, if your web application runs no javascript, disabling
273−XSRF entirely may be required.

1+# `servant-client-jsaddle`
2+
3+This is a an implementation of the `servant-client-core` API on top of `jsaddle`, a framework that lets you write Haskell programs that compile to javascript to run in a browser or compile to native code that connects to a browser.
4+
5+It is similar to `servant-client-ghcjs`, except it supports native compilation and native GHCi. It even reuses some of the logic from `servant-client-ghcjs`.
6+
7+# Build
8+
9+This package comes with a test suite that depends on `jsaddle-webkit2gtk`. You may want to skip that because of the heavy dependency footprint.
10+
11+ cabal new-build --allow-newer=aeson,http-types --disable-tests
12+
13+# Usage
14+
15+TBD. Similar to `servant-client` and `servant-client-ghcjs`.

20− which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
21− related to hash collisions.
22−- Add `NamedRoutes` combinator, making support for records first-class in Servant
23− ([#1388](https://github.com/haskell-servant/servant/pull/1388)).

90−
91− ```haskell
92− :<|> "capture-lenient" :> Capture' '[Lenient] "foo" Int :> GET
93− ```
94−
95− which will make the capture always succeed. Handlers will be of the
96− type `Either String CapturedType`, where `Left err` represents
97− the possible parse failure.

100−
101− Some APIs need query parameters rewriting, e.g. in order to support
102− for multiple casing (camel, snake, etc) or something to that effect.
103−
104− This could be easily achieved by using WAI Middleware and modifying
105− request's `Query`. But QueryParam, QueryParams and QueryFlag use
106− `rawQueryString`. By using `queryString` rather then `rawQueryString`
107− we can enable such rewritings.

109−- *servant* *servant-server* Make packages `build-type: Simple` [#1263](https://github.com/haskell-servant/servant/pull/1263)
110−
111− We used `build-type: Custom`, but it's problematic e.g.
112− for cross-compiling. The benefit is small, as the doctests
113− can be run other ways too (though not so conveniently).

8−
9−![servant-swagger robot](http://s16.postimg.org/rndz1wbyt/servant.png)
10−
11−### Motivation
12−
13−Swagger is a project used to describe and document RESTful APIs.
14−Unlike Servant it is language-agnostic and thus is quite popular among developers
15−in different languages. It also exists for a longer time and has more tools to work with.
16−
17−This package provides means to generate Swagger specification for a Servant API
18−and also to partially test whether API conforms with its specification.
19−
20−Generated Swagger specification then can be used for many things such as
21−- displaying interactive documentation using [Swagger UI](http://swagger.io/swagger-ui/);
22−- generating clients and servers in many languages using [Swagger Codegen](http://swagger.io/swagger-codegen/);
23−- and [many others](http://swagger.io/open-source-integrations/).
24−
25−### Usage
26−
27−Please refer to [haddock documentation](http://hackage.haskell.org/package/servant/servant-swagger).
28−
29−Some examples can be found in [`example/` directory](/example).
30−
31−### Try it out
32−
33−All generated swagger specifications can be interactively viewed on [Swagger Editor](http://editor.swagger.io/).
34−
35−Ready-to-use specification can be served as JSON and interactive API documentation
36−can be displayed using [Swagger UI](https://github.com/swagger-api/swagger-ui).
37−
38−Many Swagger tools, including server and client code generation for many languages, can be found on
39−[Swagger's Tools and Integrations page](http://swagger.io/open-source-integrations/).
40−
41−### Contributing

7−-- This module provides means to generate and manipulate
8−-- Swagger specification for servant APIs.
9−--
10−-- Swagger is a project used to describe and document RESTful APIs.
11−--
12−-- The Swagger specification defines a set of files required to describe such an API.
13−-- These files can then be used by the Swagger-UI project to display the API
14−-- and Swagger-Codegen to generate clients in various languages.
15−-- Additional utilities can also take advantage of the resulting files, such as testing tools.

81−-- $howto
82−--
83−-- This section explains how to use this library to generate Swagger specification,
84−-- modify it and run automatic tests for a servant API.
85−--
86−-- For the purposes of this section we will use this servant API:
87−--
88−-- >>> data User = User { name :: String, age :: Int } deriving (Show, Generic, Typeable)
89−-- >>> newtype UserId = UserId Integer deriving (Show, Generic, Typeable, ToJSON)
90−-- >>> instance ToJSON User
91−-- >>> instance ToSchema User
92−-- >>> instance ToSchema UserId
93−-- >>> instance ToParamSchema UserId
94−-- >>> type GetUsers = Get '[JSON] [User]
95−-- >>> type GetUser = Capture "user_id" UserId :> Get '[JSON] User
96−-- >>> type PostUser = ReqBody '[JSON] User :> Post '[JSON] UserId
97−-- >>> type UserAPI = GetUsers :<|> GetUser :<|> PostUser
98−--
99−-- Here we define a user API with three endpoints. @GetUsers@ endpoint returns a list of all users.
100−-- @GetUser@ returns a user given his\/her ID. @PostUser@ creates a new user and returns his\/her ID.
101−
102−-- $generate
103−-- In order to generate @'Swagger'@ specification for a servant API, just use @'toSwagger'@:
104−--
105−-- >>> BSL8.putStrLn . orderedKeys $ toSwagger (Proxy :: Proxy UserAPI)
106−-- {"definitions":{"User":{"properties":{"age":{"maximum":9223372036854775807,"minimum":-9223372036854775808,"type":"integer"},"name":{"type":"string"}},"required":["name","age"],"type":"object"},"UserId":{"type":"integer"}},"info":{"title":"","version":""},"paths":{"/":{"get":{"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"items":{"$ref":"#/definitions/User"},"type":"array"}}}},"post":{"consumes":["application/json;charset=utf-8"],"parameters":[{"in":"body","name":"body","required":true,"schema":{"$ref":"#/definitions/User"}}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/UserId"}},"400":{"description":"Invalid `body`"}}}},"/{user_id}":{"get":{"parameters":[{"in":"path","name":"user_id","required":true,"type":"integer"}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/User"}},"400":{"description":"Invalid `user_id`"}}}}},"swagger":"2.0"}
107−--
108−-- By default @'toSwagger'@ will generate specification for all API routes, parameters, headers, responses and data schemas.
109−--
110−-- For some parameters it will also add 400 responses with a description mentioning parameter name.
111−--
112−-- Data schemas come from @'ToParamSchema'@ and @'ToSchema'@ classes.
113−
114−-- $annotate
115−-- While initially generated @'Swagger'@ looks good, it lacks some information it can't get from a servant API.
116−--
117−-- We can add this information using field lenses from @"Data.Swagger"@:
118−--
119−-- >>> :{
120−-- BSL8.putStrLn $ orderedKeys $ toSwagger (Proxy :: Proxy UserAPI)

128−--
129−-- It is also useful to annotate or modify certain endpoints.
130−-- @'subOperations'@ provides a convenient way to zoom into a part of an API.
131−--
132−-- @'subOperations' sub api@ traverses all operations of the @api@ which are also present in @sub@.
133−-- Furthermore, @sub@ is required to be an exact sub API of @api. Otherwise it will not typecheck.
134−--
135−-- @"Data.Swagger.Operation"@ provides some useful helpers that can be used with @'subOperations'@.
136−-- One example is applying tags to certain endpoints:
137−--
138−-- >>> let getOps = subOperations (Proxy :: Proxy (GetUsers :<|> GetUser)) (Proxy :: Proxy UserAPI)
139−-- >>> let postOps = subOperations (Proxy :: Proxy PostUser) (Proxy :: Proxy UserAPI)
140−-- >>> :{
141−-- BSL8.putStrLn $ orderedKeys $ toSwagger (Proxy :: Proxy UserAPI)
142−-- & applyTagsFor getOps ["get" & description ?~ "GET operations"]
143−-- & applyTagsFor postOps ["post" & description ?~ "POST operations"]
144−-- :}
145−-- {"definitions":{"User":{"properties":{"age":{"maximum":9223372036854775807,"minimum":-9223372036854775808,"type":"integer"},"name":{"type":"string"}},"required":["name","age"],"type":"object"},"UserId":{"type":"integer"}},"info":{"title":"","version":""},"paths":{"/":{"get":{"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"items":{"$ref":"#/definitions/User"},"type":"array"}}},"tags":["get"]},"post":{"consumes":["application/json;charset=utf-8"],"parameters":[{"in":"body","name":"body","required":true,"schema":{"$ref":"#/definitions/User"}}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/UserId"}},"400":{"description":"Invalid `body`"}},"tags":["post"]}},"/{user_id}":{"get":{"parameters":[{"in":"path","name":"user_id","required":true,"type":"integer"}],"produces":["application/json;charset=utf-8"],"responses":{"200":{"description":"","schema":{"$ref":"#/definitions/User"}},"400":{"description":"Invalid `user_id`"}},"tags":["get"]}}},"swagger":"2.0","tags":[{"description":"GET operations","name":"get"},{"description":"POST operations","name":"post"}]}
146−--
147−-- This applies @\"get\"@ tag to the @GET@ endpoints and @\"post\"@ tag to the @POST@ endpoint of the User API.
148−
149−-- $test
150−-- Automatic generation of data schemas uses @'ToSchema'@ instances for the types
151−-- used in a servant API. But to encode/decode actual data servant uses different classes.
152−-- For instance in @UserAPI@ @User@ is always encoded/decoded using @'ToJSON'@ and @'FromJSON'@ instances.
153−--
154−-- To be sure your Haskell server/client handles data properly you need to check
155−-- that @'ToJSON'@ instance always generates values that satisfy schema produced
156−-- by @'ToSchema'@ instance.
157−--
158−-- With @'validateEveryToJSON'@ it is possible to test all those instances automatically,
159−-- without having to write down every type:
160−--
161−-- >>> instance Arbitrary User where arbitrary = User <$> arbitrary <*> arbitrary
162−-- >>> instance Arbitrary UserId where arbitrary = UserId <$> arbitrary
163−-- >>> hspec $ validateEveryToJSON (Proxy :: Proxy UserAPI)
164−-- <BLANKLINE>
165−-- [User]...
166−-- ...
167−-- User...
168−-- ...
169−-- UserId...
170−-- ...
171−-- Finished in ... seconds
172−-- 3 examples, 0 failures
173−--
174−-- Although servant is great, chances are that your API clients don't use Haskell.
175−-- In many cases @swagger.json@ serves as a specification, not a Haskell type.
176−--
177−-- In this cases it is a good idea to store generated and annotated @'Swagger'@ in a @swagger.json@ file
178−-- under a version control system (such as Git, Subversion, Mercurial, etc.).
179−--
180−-- It is also recommended to version API based on changes to the @swagger.json@ rather than changes
181−-- to the Haskell API.
182−--
183−-- See <example/test/TodoSpec.hs TodoSpec.hs> for an example of a complete test suite for a swagger specification.
184−
185−-- $serve
186−-- If you're implementing a server for an API, you might also want to serve its @'Swagger'@ specification.
187−--
188−-- See <example/src/Todo.hs Todo.hs> for an example of a server.

8−### Significant changes
9−
10−- Drop support for GHC < 8.6.
11−- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
12−- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
13− which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
14− related to hash collisions.
15−- Add `NamedRoutes` combinator, making support for records first-class in Servant
16− ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
17−
18− Users can now directly mark part as an API as defined by a record, instead of
19− using `(:<|>)` to combine routes. Concretely, the anonymous:
20−
21− ```haskell
22− type API =
23− "version" :> Get '[JSON] String :<|>
24− "products" :> Get '[JSON] [Product]
25− ```
26−
27− can be replaced with the explicitly-named:
28−
29− ```haskell
30− type API = NamedRoutes NamedAPI
31− data NamedAPI mode = NamedAPI
32− { version :: mode :- "version" :> Get '[JSON] String
33− , products :: mode :- "products" :> Get '[JSON] [Product]
34− }
35− ```
36−
37− `NamedRoutes` builds upon `servant-generic`, but improves usability by freeing
38− users from the need to perform `toServant` / `fromServant` conversions
39− manually. Serving `NamedRoutes NamedAPI` is now done directly by providing a
40− record of handlers, and servant generates clients directly as records as well.
41− In particular, it makes it much more practical to work with nested hierarchies
42− of named routes.
43−
44− Two convenience functions, `(//)` and `(/:)`, have been added to make the
45− usage of named route hierarchies more pleasant:
46−
47− ```haskell
48− rootClient :: RootApi (AsClientT ClientM)
49− rootClient = client (Proxy @API)
50−
51− helloClient :: String -> ClientM String
52− helloClient name = rootClient // hello /: name
53−
54− endpointClient :: ClientM Person
55− endpointClient = rootClient // subApi /: "foobar123" // endpoint
56−
57− type Api = NamedRoutes RootApi
58−
59− data RootApi mode = RootApi
60− { subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
61− , hello :: mode :- Capture "name" String :> Get '[JSON] String
62− , …
63− } deriving Generic
64−
65− data SubApi mode = SubApi
66− { endpoint :: mode :- Get '[JSON] Person
67− , …
68− } deriving Generic
69− ```
70−
71−- Add custom type errors for partially applied combinators
72− ([#1289](https://github.com/haskell-servant/servant/pull/1289),
73− [#1486](https://github.com/haskell-servant/servant/pull/1486)).
74−
75− For example, forgetting to document the expected type for a query parameter,
76− as in:
77−
78− ``` haskell
79− type API = QueryParam "param" :> Get '[JSON] NoContent
80− ```
81−
82− will raise to the following error when trying to serve the API:
83−
84− ```
85− • There is no instance for HasServer (QueryParam'
86− '[Optional, Strict] "param" :> ...)
87− QueryParam' '[Optional, Strict] "1" expects 1 more arguments
88− ```
89−
90− As a consequence of this change, unsaturated types are now forbidden before `(:>)`.
91−
92−- Add a `HeadNoContent` verb ([#1502](https://github.com/haskell-servant/servant/pull/1502)).
93−
94−- *servant-client* / *servant-client-core* / *servant-http-streams*:
95− Fix erroneous behavior, where only 2XX status codes would be considered
96− successful, irrelevant of the status parameter specified by the verb
97− combinator. ([#1469](https://github.com/haskell-servant/servant/pull/1469))
98−

100− `Servant.Client.Core.Request`.
101−

104− in Query parameters.

178−
179− The `NoContent` API endpoints should now use `NoContentVerb` combinator.
180− The API type changes are usually of the kind
181−

184− + :<|> PostNoContent
185− ```
186−
187− i.e. one doesn't need to specify the content-type anymore. There is no content.
188−
189−- `Capture` can be `Lenient` [#1155](https://github.com/haskell-servant/servant/issues/1155) [#1156](https://github.com/haskell-servant/servant/pull/1156)
190−

192−
193− ```haskell
194− :<|> "capture-lenient" :> Capture' '[Lenient] "foo" Int :> GET
195− ```
196−
197− which will make the capture always succeed. Handlers will be of the
198− type `Either String CapturedType`, where `Left err` represents
199− the possible parse failure.
200−
201−- *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)
202−
203− The new member `makeClientRequest` of `ClientEnv` is used to create
204− `http-client` `Request` from `servant-client-core` `Request`.
205− This functionality can be used for example to set
206− dynamic timeouts for each request.
207−
208−- *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)
209−
210− Some APIs need query parameters rewriting, e.g. in order to support
211− for multiple casing (camel, snake, etc) or something to that effect.
212−
213− This could be easily achieved by using WAI Middleware and modifying
214− request's `Query`. But QueryParam, QueryParams and QueryFlag use
215− `rawQueryString`. By using `queryString` rather then `rawQueryString`
216− we can enable such rewritings.
217−
218−- *servant* *servant-server* Make packages `build-type: Simple` [#1263](https://github.com/haskell-servant/servant/pull/1263)
219−
220− We used `build-type: Custom`, but it's problematic e.g.
221− for cross-compiling. The benefit is small, as the doctests
222− can be run other ways too (though not so conveniently).
223−
224−- *servant* Remove deprecated modules [1268#](https://github.com/haskell-servant/servant/pull/1268)
225−
226− - `Servant.Utils.Links` is `Servant.Links`
227− - `Servant.API.Internal.Test.ComprehensiveAPI` is `Servant.Test.ComprehensiveAPI`
228−
229−### Other changes
230−
231−- *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)
232−
233− For `Verb`s with response `Headers`, the implementation didn't check
234− for the content-type of the response. Now it does.
235−
236−- *servant-docs* Merge documentation from duplicate routes [#1240](https://github.com/haskell-servant/servant/issues/1240) [#1241](https://github.com/haskell-servant/servant/pull/1241)
237−
238− Servant supports defining the same route multiple times with different
239− content-types and result-types, but servant-docs was only documenting
240− the first of copy of such duplicated routes. It now combines the
241− documentation from all the copies.
242−
243− Unfortunately, it is not yet possible for the documentation to specify
244− multiple status codes.
