  • new switch [RoutedMode] MatchH239SessionsByIDOnly= to never attempt to match a H.239 reverse channel by type for improved interoperability with EdgeProtect
  • new switches to set the HTTP Content-Type header in HttpAcct, HttpPasswordAuth and Routing::Http

  • better endpointIDs on Windows when compiling without OpenSSL
