  • Add X-Content-Type-Options: nosniff headers to responses (fixes #102)
  • Add a request.current_service attribute (fixes #105)

Bug fixes

  • Fix cornice.cors.get_cors_preflight_view to make it parse Access-Control-Request-Headers header correctly event if its value contains zero number of white spaces between commas (#422)
