4- **Addition of the 'Servant.Reflex.Multi' module** which allows the user

5to choose some '(Applicative f, Traversable f) => f' for collecting

6endpoint parameters. The traversable instance is used for passing

7multiple 'XhrRequest's in response to a single event trigger. The

8Applicative instance is used to combine parameters. For example,

9'Capture "id" Name :> QueryParam "greeting" Text :> Get '[JSON] Text'

10will generate a client function:

11`Dynamic t (f Name) -> Dynamic t (f greeting) -> Event t tag ->

12 m (Event t (f (ReqResult tag Text)))`

13Calling that function with 'f' chosen to be list ('[]'), this call

14`clientFun

15(constDyn ["Greg", "Bernie"])

16(constDyn ["Greetings", "Hey"])

17trigger`

18would produce four XhrRequests per 'trigger' event, one for each

19combination of possible parameters, and one response event

20would carry a list of the four responses.

21A 'zip-wise' combination of the parameters can be chosen with

22a different applicative wrapper: 'ZipList'

24- **Event tags**. A new type parameter lets users choose a payload

25value to attach to outgoing requests at the point of triggering,

26and which is embedded in the response, allowing individual

27request-response pairs to be followed. The response's tag has been

28added to each constructor `ReqResult tag a` type.

30- **Improved Unicode support** Thanks to Schell Scivally

31(https://github.com/schell) for identifying and fixing a UTF-8

32encoding bug!
