Features/Changes

• Misc: update testsuite to OCaml 5.2
• Misc: CI uses opam.2.2 and no longer use sunset repo
• Misc: yojson is no longer optional
• Misc: reduce the diff with the wasm_of_ocaml fork
• Misc: finalize support for OCaml 5.3
• Compiler: speedup global_flow/global_deadcode pass on large bytecode
• Compiler: improved global dead code elimination (ocsigen/js_of_ocaml#2206)
• Compiler: speedup json parsing, relying on Yojson.Raw (extracted from #1617 ocsigen/js_of_ocaml#1640)
• Compiler: Decode sourcemap mappings only when necessary (Decode sourcemap mappings only when necessary ocsigen/js_of_ocaml#1664)
• Compiler: mark [TextEncoder] as reserved
• Compiler: add support for the Wasm backend in parts of the pipeline, in
  prevision for the merge of wasm_of_ocaml
• Compiler: introduce a Targetint module
  that follows the semantic of the backend (js or wasm)
• Compiler: warn on joo_global_object
• Compiler: revisit static env handling (Compiler: revisit static env handling ocsigen/js_of_ocaml#1708)
• Compiler: Emit index source_map to avoid changing mappings (Handle composite sourcemaps ocsigen/js_of_ocaml#1714, Compiler: refactor sourcemap generation, use Index sourcemap ocsigen/js_of_ocaml#1715)
• Compiler: improved source map generation (Source map improvements ocsigen/js_of_ocaml#1716)
• Runtime: change Sys.os_type on windows (Cygwin -> Win32)
• Runtime: backtraces are really expensive, they need to be explicitly
  requested at compile time (--enable with-js-error) or at startup (OCAMLRUNPARAM=b=1)
• Runtime: allow dynlink of precompiled js with separate compilation (Runtime: allow dynlink of precompiled js with separate compilation ocsigen/js_of_ocaml#1676)
• Runtime: reimplement the runtime of weak and ephemeron (Runtime: reimplement weak/ephemeron ocsigen/js_of_ocaml#1707)
• Lib: Modify Typed_array API for compatibility with WebAssembly
• Lib: add details element and toggle event (Add detailsElement and toggleEvent objects. ocsigen/js_of_ocaml#1728)
• Toplevel: no longer set globals for toplevel initialization
• Runtime: precompute constants used in caml_lxm_next (precompute prng lxm constants ocsigen/js_of_ocaml#1730)
• Runtime: cleanup runtime

Bug fixes

• Runtime: fix parsing of unsigned integers (0u2147483648) (Runtime: fix #1630 ocsigen/js_of_ocaml#1633, Runtime: fix parsing of unsigned int64 ocsigen/js_of_ocaml#1666)
• Runtime: fix incorrect pos_in after unmarshalling
• Runtime: make float_of_string stricter (Add Typed_array.Bytes module ocsigen/js_of_ocaml#1609)
• Toplevel: fix missing primitives with separate compilation
• Compiler: fix link of packed modules with separate compilation
• Compiler: Fixed the static evaluation of some equalities (Document non-trivial function Code.constant_equal, and fix related bugs ocsigen/js_of_ocaml#1659)
• Compiler: fix global analysis bug (subsumes Compiler: fix toplevel with globaldeacode ocsigen/js_of_ocaml#1556)
