The latest version of this document is on GitHub. Changelog for servant package contains significant entries for all core packages.

0.15

• Streaming refactoring. #991 #1076 #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 servant-pipes and 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

  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.

  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 #1009

• servant-client-core Add NFData (GenResponse a) and NFData ServantError instances. #1076

servant-client-core Add aeson and Lift BaseUrl instances #1037

0.14

• Stream takes a status code argument

  -Stream method        framing ctype a
  +Stream method status framing ctype a
  

  (#966 #972)

• ToStreamGenerator definition changed, so it's possible to write an instance for conduits.

  -class ToStreamGenerator f a where
  -   toStreamGenerator :: f a -> StreamGenerator a
  +class ToStreamGenerator a b | a -> b where
  +   toStreamGenerator :: a -> StreamGenerator b
  

  (#959)

• Added NoFraming streaming strategy (#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 in, we also have hoistClient for changing the monad in which client functions live. Read tutorial section for more information. (#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)

0.13.0.1

• Support base-compat-0.10

0.13

• Streaming endpoint support. (#836)
• servant Add Servant.API.Modifiers (#873)
• servant-client Support http-client’s CookieJar (#897 #883)

0.12.0.1

• Send Accept header. (#858)

0.12

• Factored out into servant-client-core all the functionality that was independent of the http-client backend.

0.11

Other changes

• Path components are escaped (#696)
• Req reqPath field changed from String to BS.Builder (#696)
• Include Req in failure errors (#740)

0.10

Breaking changes

There shouldn't be breaking changes. Released as a part of servant suite.

Other changes

• Add MonadBase and MonadBaseControl instances for ClientM (#663)

• client asks for any content-type in Accept contentTypes non-empty list (#615)

• Add ClientLike class that matches client functions generated using client with client data structure. (#640)

• Allow direct use of 'RequestBody' (#661)

0.9.1.1

• Add MonadThrow and MonadCatch instances for ClientM

0.9

• BACKWARDS INCOMPATIBLE: client now returns a ClientM which is a Reader for BasicEnv. BasicEnv comprises the HttpManager and BaseUrl that have had to be passed to each method returned by client.

0.7.1

• Support GHC 8.0
• ServantError has an Eq instance now.

0.6

• client no longer takes BaseUrl and Manager arguments. Instead, each function returned by client requires these two arguments.

0.5

• Use the text package instead of String.
• Support for the HttpVersion, IsSecure, RemoteHost and Vault combinators
• Added support for path on BaseUrl.
• client now takes an explicit Manager argument.
• Use http-api-data instead of Servant.Common.Text
• Client functions now consider any 2xx successful.
• Remove matrix params.
• Added support for Basic authentication
• Add generalized authentication support via the AuthClientData type family and AuthenticateReq data type

0.4.1

• The HasClient instance for Delete cts () now does not care at all about content types provided.

0.4

• Delete now is like Get, Post, Put, and Patch and returns a response body
• Support content-type aware combinators and Accept/Content-type headers
• Added a lot of tests
• Support multiple concurrent threads
• Use ServantError to report Errors instead of String
• Make the clients for Raw endpoints return the whole Response value (to be able to access response headers for example)
• Support for PATCH
• Make () instances expect No Content status code, and not try to decode body.
• Add support for response headers

0.2.2

• Add TLS support
• Add matrix parameter support
