Significant changes

• Add NoContentVerb #1028 #1219 #1228

  The NoContent API endpoints should now use NoContentVerb combinator. The API type changes are usually of the kind

  - :<|> 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 #1156

  You can specify a lenient capture as

  :<|> "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.
