2.3.0 (2019-01-31)

The new feature in this release is to automatically install printers marked with [@@ocaml.toplevel_printer] (#269 @diml). Adding this annotation to your libraries will remove the need to have a separate top package to install the printers.

For example, in the uri library, the old printing function for Uri.t was:

val pp_hum : Format.formatter -> t -> unit

Just adding this annotation results in Uri.t values being automatically pretty printed in this version of utop.

val pp_hum : Format.formatter -> t -> unit [@@ocaml.toplevel_printer]
