CHANGES:

• Support Sys.opaque_identity to turn off optimizations
  (#1276)
• Upgrade the Melange JS parser to Flow
  v0.266.0
  (#1380)
• Add [@mel.spread] in externals to spread polymorphic variants with
  payloads (#1404)
• melange.ppx: improve the inference of @mel.as in polymorphic variant
  arguments to externals, allow to mix ints and strings in the different
  variant branches (#1418)
• Fix code generation bug when assigning functions to variables
  (#1429)
• Allow @mel.int polymorphic variants in externals to carry payload
  (#1419)
• support null variants @mel.as in mixed @mel.unwrap
  (#1442)
• melc: exit when --modules is passed instead of proceeding to compile
  (#1478)
• Optimize file reading / writing in Melange
  (#1457,
  #1459)
• add -cmi-file for flag compatibility with upstream OCaml
  (#1488)
• code generation: inline more binary operations
  (#1526)
• code generation: fix wrong optimization related to option unnesting
  (#1530)
• code generation: omit undefined argument on foo () unit application
  (#1538)
• code generation: omit undefined trailing arguments when generating
  JavaScript, e.g. those that are optionally labeled don't become explicitly
  undefined in the JavaScript output
  (#1564)
• BREAKING(runtime): consolidate functions in Js.Date to account for the recent
  improvement in code generation related to omitting trailing undefined
  arguments (#1597)
• BREAKING(ppx): Remove [@@deriving abstract] in favor of:
  • [@@deriving jsProperties] derives a JS object creation function that
    can generate a JS object with optional keys (when using [@mel.optiona])
  • [@@deriving getSet] derives getter / setter functions for the JS object
    derived by the underlying record.
  • [@@deriving abstract] had been deprecated since Melange 5 (in
    #979), and has now been
    removed in #1624
• runtime: support more functions in Stdlib.Float
  (#1625)
• Upgrade the Melange JS parser to Flow
  v0.288.0
  (#1627)
• runtime: add more functions to Js.Array module
  (#1635)
• core: update reserved keywords list to account for new browser additions
  (#1644)
• ppx: disallow empty %raw expressions, which would cause syntax errors in
  code generation (#1651)
• ppx: support all valid Longidents in string interpolation
  (#1653)
