2+prs: #1556
3+
4+description: {
5+
6+This PR enhances the `Servant.Server.layout` function, which produces a textual description of the routing layout of an API. More precisely, it changes `<capture>` blocks, so that they display the name and type of the variable being captured instead.
7+
8+Example:
9+
10+For the following API
11+```haskell
12+type API =
13+ "a" :> "d" :> Get '[JSON] NoContent
14+ :<|> "b" :> Capture "x" Int :> Get '[JSON] Bool
15+ :<|> "a" :> "e" :> Get '[JSON] Int
16+```
17+
18+we previously got the following output:
19+
20+```
21+/
22+├─ a/
23+│ ├─ d/
24+│ │ └─•
25+│ └─ e/
26+│ └─•
27+└─ b/
28+ └─ <capture>/
29+ ├─•
30+ ┆
31+ └─•
32+```
33+
34+now we get:
35+
36+```
37+/
38+├─ a/
39+│ ├─ d/
40+│ │ └─•
41+│ └─ e/

43+└─ b/
44+ └─ <x::Int>/
45+ ├─•
46+ ┆
47+ └─•
48+```
49+
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)
67+myServer = const $ return ()
68+
69+myApi :: forall a. Proxy (MyAPI a)
70+myApi = Proxy
71+
72+app :: forall a. (FromHttpApiData a) => Application
73+app = serve (myApi @a) (myServer @a)
74+```
75+
76+Indeed, `app` should be replaced with:
77+```haskell
78+app :: forall a. (FromHttpApiData a, Typeable a) => Application
79+app = serve (myApi @a) (myServer @a)

1+# Request-lifetime Managed Resources
2+
3+Let's see how we can write a handle that uses a resource managed by Servant. The resource is created automatically by Servant when the server recieves a request, and the resource is automatically destroyed when the server is finished handling a request.
4+
5+As usual, we start with a little bit of throat clearing.
6+
7+

21+```
22+
23+Here we define an API type that uses the `WithResource` combinator. The server handler for an endpoint with a `WithResource res` component will receive a value of that type as an argument.
24+
25+``` haskell
26+type API = WithResource Handle :> ReqBody '[PlainText] String :> Post '[JSON] NoContent
27+
28+api :: Proxy API
29+api = Proxy
30+```
31+
32+But this resource value has to come from somewhere. Servant obtains the value using an Acquire provided in the context. The Acquire knows how to both create and destroy resources of a particular type.
33+
34+``` haskell
35+appContext :: Context '[Acquire Handle]
36+appContext = acquireHandle :. EmptyContext

41+newHandle :: IO Handle
42+newHandle = do

44+ h <- openFile "test.txt" AppendMode

46+ return h
47+
48+closeHandle :: Handle -> IO ()
49+closeHandle h = do
50+ putStrLn "closing file"
51+ hClose h
52+ putStrLn "closed file"
53+```
54+
55+Now we create the handler which will use this resource. This handler will write the request message to the System.IO.Handle which was provided to us. In some situations the handler will succeed, but in some in will fail. In either case, Servant will clean up the resource for us.
56+
57+``` haskell
58+server :: Server API
59+server = writeToFile

64+ legalMsg -> liftIO $ do
65+ putStrLn "writing file"
66+ hPutStrLn h legalMsg
67+ putStrLn "wrote file"
68+ return NoContent
69+```
70+
71+Finally we run the server in the background while we post messages to it.
72+
73+``` haskell
74+runApp :: IO ()
75+runApp = run 8080 (serveWithContext api appContext $ server)

114+and appends to a file called `test.txt`. We can see from the output that when a legal message is sent, the file is opened, written to, and closed. We can also see that when an illegal message is sent, the file is opened but not written to. Crucially, it is still closed even though the handler threw an exception.

44+Note for Ubuntu users
45+--------
46+
47+Ubuntu's packages for `ghc`, `cabal`, and `stack` are years out of date.
48+If the instructions above fail for you,
49+try replacing the Ubuntu packages with up-to-date versions.
50+First remove the installed versions:
51+
52+.. code-block:: bash
53+
54+ # remove the obsolete versions
55+ $ sudo apt remove ghc haskell-stack cabal-install
56+
57+Then install fresh versions of the Haskell toolchain
58+using the `ghcup <https://www.haskell.org/ghcup/install/>`_ installer.
59+
60+As of February 2022, one easy way to do this is by running a bootstrap script:
61+
62+.. code-block:: bash
63+
64+ $ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
65+
66+The script is interactive and will prompt you for details about what
67+you want installed and where. To install manually,
68+see `the detailed instructions <https://www.haskell.org/ghcup/install/#manual-install>`_.

9+### Significant changes
10+
11+- Drop support for GHC < 8.6.
12+- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
13+- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
14+ which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
15+ related to hash collisions.
16+- Add `NamedRoutes` combinator, making support for records first-class in Servant
17+ ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
18+- Add custom type errors for partially applied combinators
19+ ([#1289](https://github.com/haskell-servant/servant/pull/1289),
20+ [#1486](https://github.com/haskell-servant/servant/pull/1486)).
21+- *servant-client* / *servant-client-core* / *servant-http-streams*: Fix
22+ erroneous behavior, where only 2XX status codes would be considered
23+ successful, irrelevant of the status parameter specified by the verb
24+ combinator. ([#1469](https://github.com/haskell-servant/servant/pull/1469))
25+- *servant-client* / *servant-client-core*: Fix `Show` instance for
26+ `Servant.Client.Core.Request`.
27+- *servant-client* / *servant-client-core*: Allow passing arbitrary binary data
28+ in Query parameters.
29+ ([#1432](https://github.com/haskell-servant/servant/pull/1432)).

9+### Significant changes
10+
11+- Drop support for GHC < 8.6.
12+- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
13+- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
14+ which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
15+ related to hash collisions.
16+- Add `NamedRoutes` combinator, making support for records first-class in Servant
17+ ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
18+- Add custom type errors for partially applied combinators
19+ ([#1289](https://github.com/haskell-servant/servant/pull/1289),
20+ [#1486](https://github.com/haskell-servant/servant/pull/1486)).
21+- *servant-client* / *servant-client-core* / *servant-http-streams*: Fix
22+ erroneous behavior, where only 2XX status codes would be considered
23+ successful, irrelevant of the status parameter specified by the verb
24+ combinator. ([#1469](https://github.com/haskell-servant/servant/pull/1469))
25+- *servant-client* / *servant-client-core*: Fix `Show` instance for
26+ `Servant.Client.Core.Request`.
27+- *servant-client* / *servant-client-core*: Allow passing arbitrary binary data
28+ in Query parameters.
29+ ([#1432](https://github.com/haskell-servant/servant/pull/1432)).

5+
6+0.19.2
7+------
8+
9+Compatibility with GHC 9.4, see [PR #1592](https://github.com/haskell-servant/servant/pull/1592).
10+
11+0.19.1
12+------
13+
14+- Add `MonadFail` instance for `Handler` wrt [#1545](https://github.com/haskell-servant/servant/issues/1545)
15+- Support GHC 9.2 [#1525](https://github.com/haskell-servant/servant/issues/1525)
16+- Add capture hints in `Router` type for debug and display purposes [PR #1556] (https://github.com/haskell-servant/servant/pull/1556)
17+
18+0.19
19+----
20+
21+### Significant changes
22+
23+- Drop support for GHC < 8.6.
24+- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
25+- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
26+ which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
27+ related to hash collisions.
28+- Add `NamedRoutes` combinator, making support for records first-class in Servant
29+ ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
30+- Add custom type errors for partially applied combinators
31+ ([#1289](https://github.com/haskell-servant/servant/pull/1289),
32+ [#1486](https://github.com/haskell-servant/servant/pull/1486)).

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
42+
43+We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.
44+
45+Please report bugs via the [github issue tracker](https://github.com/haskell-servant/servant/issues).

4+synopsis: Generate a Swagger/OpenAPI/OAS 2.0 specification for your servant API.
5+description:
6+ Swagger is a project used to describe and document RESTful APIs. The core of the
7+ project is the [OpenAPI Specification (OAS)](https://swagger.io/docs/specification/about/).
8+ This library implements v2.0 of the spec. Unlike Servant it is language-agnostic and thus is
9+ quite popular among developers in different languages. It has also existed for a longer time
10+ and has more helpful tooling.
11+ .
12+ This package provides means to generate a Swagger/OAS specification for a Servant API
13+ and also to partially test whether an API conforms with its specification.
14+ .
15+ Generated Swagger specification then can be used for many things such as
16+ .
17+ * displaying interactive documentation using [Swagger UI](http://swagger.io/swagger-ui/);
18+ .
19+ * generating clients and servers in many languages using [Swagger Codegen](http://swagger.io/swagger-codegen/);
20+ .
21+ * and [many others](http://swagger.io/open-source-integrations/).

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)
121+-- & info.title .~ "User API"
122+-- & info.version .~ "1.0"
123+-- & info.description ?~ "This is an API for the Users service"
124+-- & info.license ?~ "MIT"
125+-- & host ?~ "example.com"
126+-- :}
127+-- {"definitions":{"User":{"properties":{"age":{"maximum":9223372036854775807,"minimum":-9223372036854775808,"type":"integer"},"name":{"type":"string"}},"required":["name","age"],"type":"object"},"UserId":{"type":"integer"}},"host":"example.com","info":{"description":"This is an API for the Users service","license":{"name":"MIT"},"title":"User API","version":"1.0"},"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"}
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.

3+Package versions follow the [Package Versioning Policy](https://pvp.haskell.org/): in A.B.C, bumps to either A or B represent major versions.
4+
5+0.19.1
6+------
7+
8+Compatibility with GHC 9.4, see [PR #1592](https://github.com/haskell-servant/servant/pull/1592).
9+
10+0.19
11+----
12+
13+### Significant changes
14+
15+- Drop support for GHC < 8.6.
16+- Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
17+- Support Aeson 2 ([#1475](https://github.com/haskell-servant/servant/pull/1475)),
18+ which fixes a [DOS vulnerability](https://github.com/haskell/aeson/issues/864)
19+ related to hash collisions.
20+- Add `NamedRoutes` combinator, making support for records first-class in Servant
21+ ([#1388](https://github.com/haskell-servant/servant/pull/1388)).
22+
23+ Users can now directly mark part as an API as defined by a record, instead of
24+ using `(:<|>)` to combine routes. Concretely, the anonymous:
25+
26+ ```haskell
27+ type API =
28+ "version" :> Get '[JSON] String :<|>
29+ "products" :> Get '[JSON] [Product]
30+ ```
31+
32+ can be replaced with the explicitly-named:
33+
34+ ```haskell
35+ type API = NamedRoutes NamedAPI
36+ data NamedAPI mode = NamedAPI
37+ { version :: mode :- "version" :> Get '[JSON] String
38+ , products :: mode :- "products" :> Get '[JSON] [Product]
39+ }
40+ ```
41+
42+ `NamedRoutes` builds upon `servant-generic`, but improves usability by freeing
43+ users from the need to perform `toServant` / `fromServant` conversions
44+ manually. Serving `NamedRoutes NamedAPI` is now done directly by providing a
45+ record of handlers, and servant generates clients directly as records as well.
46+ In particular, it makes it much more practical to work with nested hierarchies
47+ of named routes.
48+
49+ Two convenience functions, `(//)` and `(/:)`, have been added to make the
50+ usage of named route hierarchies more pleasant:
51+
52+ ```haskell
53+ rootClient :: RootApi (AsClientT ClientM)
54+ rootClient = client (Proxy @API)
55+
56+ helloClient :: String -> ClientM String
57+ helloClient name = rootClient // hello /: name
58+
59+ endpointClient :: ClientM Person
60+ endpointClient = rootClient // subApi /: "foobar123" // endpoint
61+
62+ type Api = NamedRoutes RootApi
63+
64+ data RootApi mode = RootApi
65+ { subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
66+ , hello :: mode :- Capture "name" String :> Get '[JSON] String
67+ , …
68+ } deriving Generic
69+
70+ data SubApi mode = SubApi
71+ { endpoint :: mode :- Get '[JSON] Person
72+ , …
73+ } deriving Generic
74+ ```
75+
76+- Add custom type errors for partially applied combinators
77+ ([#1289](https://github.com/haskell-servant/servant/pull/1289),
78+ [#1486](https://github.com/haskell-servant/servant/pull/1486)).
79+
80+ For example, forgetting to document the expected type for a query parameter,
81+ as in:
82+
83+ ``` haskell
84+ type API = QueryParam "param" :> Get '[JSON] NoContent
85+ ```
86+
87+ will raise to the following error when trying to serve the API:
88+
89+ ```
90+ • There is no instance for HasServer (QueryParam'
91+ '[Optional, Strict] "param" :> ...)
92+ QueryParam' '[Optional, Strict] "1" expects 1 more arguments
93+ ```
94+
95+ As a consequence of this change, unsaturated types are now forbidden before `(:>)`.
96+
97+- Add a `HeadNoContent` verb ([#1502](https://github.com/haskell-servant/servant/pull/1502)).
98+
99+- *servant-client* / *servant-client-core* / *servant-http-streams*:
100+ Fix erroneous behavior, where only 2XX status codes would be considered
101+ successful, irrelevant of the status parameter specified by the verb
102+ combinator. ([#1469](https://github.com/haskell-servant/servant/pull/1469))
103+
104+- *servant-client* / *servant-client-core*: Fix `Show` instance for
105+ `Servant.Client.Core.Request`.
106+
107+
108+- *servant-client* / *servant-client-core*: Allow passing arbitrary binary data
109+ in Query parameters.
110+ ([#1432](https://github.com/haskell-servant/servant/pull/1432)).
111+
112+- *servant-docs*: Generate sample cURL requests
113+ ([#1401](https://github.com/haskell-servant/servant/pull/1401/files)).
114+
115+ Breaking change: requires sample header values to be supplied with `headers`.
116+
117+### Other changes
118+
119+- Various bit rotten cookbooks have been updated and re-introduced on
120+ [docs.servant.dev](https://docs.servant.dev).
121+
122+- Various version bumps.
