CHANGES: ## 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 (ocsigen/js_of_ocaml#1640) * Compiler: 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 (ocsigen/js_of_ocaml#1708) * Compiler: Emit index source_map to avoid changing mappings (ocsigen/js_of_ocaml#1714, ocsigen/js_of_ocaml#1715) * Compiler: improved source map generation (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 (ocsigen/js_of_ocaml#1676) * Runtime: reimplement the runtime of weak and ephemeron (ocsigen/js_of_ocaml#1707) * Lib: Modify Typed_array API for compatibility with WebAssembly * Lib: add details element and toggle event (ocsigen/js_of_ocaml#1728) * Toplevel: no longer set globals for toplevel initialization * Runtime: precompute constants used in `caml_lxm_next` (ocsigen/js_of_ocaml#1730) * Runtime: cleanup runtime ## Bug fixes * Runtime: fix parsing of unsigned integers (0u2147483648) (ocsigen/js_of_ocaml#1633, ocsigen/js_of_ocaml#1666) * Runtime: fix incorrect pos_in after unmarshalling * Runtime: make float_of_string stricter (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 (ocsigen/js_of_ocaml#1659) * Compiler: fix global analysis bug (subsumes ocsigen/js_of_ocaml#1556)
