  (#1135)
• support -H for hidden include dirs in OCaml 5.2
  (#1137)
• support [@mel.*] attributes in uncurried externals
  (#1140)
• add Worker types to melange.dom
  (#1147)
• Add support for dynamic import()
  (#1164)
• Fix code generation of custom true / false constructors
  (#1175)
• Fix code generation of OCaml objects that refers to an init variable in scope
  (#1183)
• Support [@mel.as "string"] in variant definitions
  (#884)
• BREAKING: remove [@@deriving jsConverter] for variant definitions
  (#884). Use [@mel.as "string here"] instead.

• Upgrade Stdlib to the OCaml 5.3 Stdlib
  (#1182)
• Support [@mel.tag "the_tag"] in variant definitions
  (#1189)
  • combined with [@mel.as ..] in variant definitions and inline record
    payloads, Melange can now express types for discriminated union object
    shapes.
• melange-ppx: don't silence warning 20 (ignored-extra-argument) for
  %mel.raw application
  (#1166).
  • This change reverts the behavior introduced in
    (#915).
  • The new recommendation is to annotate %mel.raw functions or disable
    warning 20 at the project level.
• ppx,core: propagate internal FFI information via attributes instead of adding
  marshalled data in the native primitive name
  (#1222)
• melange-ppx: allow @mel.unwrap polyvariants not to have a payload
  (#1239)

• melange.node: bind to all supported Node.js Buffer encodings in
  Node.Buffer (#1246)

  FormData API
  (#1153,

  Blob and
  File APIs

  (#1248)
• BREAKING: remove --mel-g
  (#1234)
• runtime(melange.js): port [@mel.send.pipe] functions to [@mel.send],
  taking advantage of the @mel.send + labeled argument improvement (see
  above) (#1260,
  #1264,
  #1265,
  #1266,
  #1280,
  #1278)
• core: fix a crash related to finding constructor names in pattern matching triggered by dune's earlier implementation of (implicit_transitive_deps false)
  (#1238,
  #1262)
• core: pre-compute the closure param map for functions inlined with
  --mel-cross-module-opt
  (#1219)
• BREAKING: ppx: print the deprecated alert for @@deriving abstract at the
  declaration site rather than at (all) usages
  (#1269)
• JS generation: prettify for loops
  (#1275)
• JS generation: improve formatting for throw and return statements, JS
  objects (#1286,
  #1289)
• JS generation: improve formatting for empty return and continue statements
  (#1288)
• JS generation: remove trailing spaces before commas in export
  (#1287)
• JS generation: remove redundant switch cases branches
  (#1295)
• JS generation: move space before comma inside for definition
  (#1296)
• JS generation: add space before while loop condition
  (#1297)
• JS generation: improve indentation of parenthesized blocks
  (#1293)
• JS generation: add space after constructor comments
  (#1294)
• JS generation: improve identation of switch cases
  (#1299)
• JS generation: don't generate empty default: cases in switch
  (#1300)
• JS generation: emit module.exports in CommonJS instead of exports.x
  (#1314)
• JS generation: remove trailing newline after switch
  (#1313)
• ffi: allow annotating @mel.send FFI with @mel.this to specify which
  parameter should represent the "self" argument.
  (#1303,
  #1310)
  • This improvement to the FFI allows expressing more FFI constructs via
    labeled and optionally labeled arguments, e.g. external foo: value:string -> (t [@mel.this]) -> unit = "foo" [@@mel.send] will now produce
    t.foo(value) instead of value.foo(t).
  • It also allows removing usages of [@mel.send.pipe: t] in favor of
    [@mel.send] with [@mel.this], including when used with @mel.variadic.
• ppx: deprecate [@mel.send.pipe]
  (#1321)
• core: fix missed optimization on OCaml versions 5.2 and above, caused by
  ocaml/ocaml#12236 generating
  multiple function nodes for fun a -> fun b -> ... in the Lambda IR.
