New release?

Using 0.6 from opam mu fails with dangling reference error, however using the latest git code from master works:

open Json_encoding
let reclist itemencoding =
  mu "list" @@ fun self ->
  union
    [ case (string_enum [ "nil", () ])
        (function [] -> Some () | _ :: _ -> None)
        (fun () -> []) ;
      case (obj2 (req "hd" itemencoding) (req "tl" self))
        (function hd :: tl -> Some (hd, tl) | [] -> None)
        (fun (hd, tl) -> hd :: tl) ];;

let () =
  try
    reclist (def "a" int) |> Json_encoding.schema |> Json_schema.to_json |> Ezjsonm.wrap |>
    Ezjsonm.to_string ~minify:false |> print_endline
  with e ->
    Format.eprintf "Error: %a@."
      (Json_encoding.print_error ?print_unknown:None)
      e

Error: Dangling reference #/definitions/a
Fatal error: exception Json_schema.Dangling_reference(_)

I think it'd be worth making a new release
