CHANGES:

• BREAKING: remove Belt as a dependency of Stdlib
  (#796,
  #797)
  • Melange no longer includes the melange.belt library by default; after
    this release, you need to add (libraries melange.belt) to your melange
    stanzas.
• Melange Runtime / Stdlib: remove deprecated modules and functions
  (#817):
  • Js.List: use Stdlib.List or Belt.List instead;
  • Js.Null_undefined: use Js.Nullable instead;
  • Js.Option: use Stdlib.Option or Belt.Option instead;
  • Js.Result: use Stdlib.Result or Belt.Result instead;
  • Js.Cast.
• BREAKING:
  • remove support for @bs / @bs.* attributes; Melange users should now
    use [@u] for uncurried application and [@mel.*] as the prefix for the
    FFI attributes (#818)
  • remove [@@mel.val], which was redundant in the Melange FFI
    (#818)
• BREAKING(runtime): rename a few keys with legacy names
  (#819):
  1. Exception ID RE_EXN_ID to MEL_EXN_ID
  2. BS_PRIVATE_NESTED_SOME_NONE option marker to
     MEL_PRIVATE_NESTED_SOME_NONE

  (#731,
  #893,
  #895,
  #899,

  • Modules ending with 2 (e.g. Js.String2, Js.Array2,
    Js.TypedArray2) are no longer available in Melange
  • The functions in their corresponding modules now take labeled arguments
    and one positional argument, prioritizing the usage of |> but still
    allowing |. (-> in Reason) when optionally labeled arguments aren't
    omitted.

  (#897)

  • [@@deriving jsProperties] derives a JS object creation function that
    can generate a JS object with optional keys (when using [@mel.optiona])

    derived by the underlying record.
• ppx: Deprecate [@@deriving abstract]
