0.19.0

• added destructuring for :headers, thanks to tchagnon!
• :path-param allows any keywords, needed for the partial parameter matching with context*
• BREAKING: parameters are collected in (Ring-)Swagger 2.0 format, might break client-side compojure.api.meta/restructure-param dispatch functions - for the swagger documentation part. See https://github.com/metosin/ring-swagger/blob/master/test/ring/swagger/swagger2_test.clj & https://github.com/metosin/compojure-api/blob/master/src/compojure/api/meta.clj for examples of the new schemas.
• context* to allow setting meta-data to mid-routes. Mid-route meta-data are deep-merged into endpoint swagger-definitions at compile-time. At runtime, code is executed in place.

(context* "/api/:kikka" []
  :summary "summary inherited from context"
  :path-params [kikka :- s/Str] ; enforced here at runtime
  :query-params [kukka :- s/Str] ; enforced here at runtime
  (GET* "/:kakka" []
    :path-params [kakka :- s/Str] ; enforced here at runtime
    (ok {:kikka kikka
         :kukka kukka
         :kakka kakka})))
