 - Represent optional parameters with defaults structurally, removing downstream name-based detection and producing more consistent JavaScript parameter names. https://github.com/rescript-lang/rescript/pull/8580
 - Sync the platform npm package's compiler binaries (`packages/@rescript/<platform>/bin`) via dune promotion on every `dune build`, instead of Makefile/CI copy steps that only ran when make did: a plain `dune build` can no longer leave `cli/*.js` and the test harnesses running a stale compiler. https://github.com/rescript-lang/rescript/pull/8560
 - Remove unused compiler IR definitions, modules, helpers, error variants, and Typedtree fields. https://github.com/rescript-lang/rescript/pull/8551 https://github.com/rescript-lang/rescript/pull/8555
-- Make Lambda-to-Lam conversion structural for lets, switches, static exits, recursive binding groups, exception packing, and eliminated identity operations. Semantic rewrites now happen during Lambda production or in named Lam passes; obsolete conversion state and `Lam_scc` are removed.
-- Remove obsolete Lambda and Lam primitives and align their scalar constant representations. Lambda and Lam now use `int32` integers and matching char, string, float, and bigint cases; Lambda strings carry their parsed output delimiter, assert-false is distinct from integer zero, and dead typedtree integer variants are removed.

 - Make locally abstract value constraints (`let f: type a. t = value`) structural in the parsetree, remove the obsolete `Pexp_newtype` and `Texp_newtype` wrapper metadata, and keep the old encoding confined to the frozen external-PPX bridge. The CMT magic number is bumped to `Caml1999T024`. https://github.com/rescript-lang/rescript/pull/8575
 - Eliminate the `Pjs_fn_make`/`Pjs_fn_make_unit` arity-adjustment primitives and the `unsafe_adjust_to_arity` machinery: with structural arity, functions are constructed at their final arity, so the enforcement layer (and the active-pattern currying split it compensated for) is deleted. Generated code improves: no adapter closures for patterns on mutable fields, better constant propagation and name preservation, and recursive modules whose members are plain functions compile statically without the runtime bootstrap. https://github.com/rescript-lang/rescript/pull/8570
 - Cleanups enabled by structural arity: remove the unreachable `Too_many_arguments` error and the `?in_function` threading through the type checker that existed only to decorate it; remove the dead `function$`-vs-arrow unification bridge, `Ctype.arity`, and the unused parsetree arity helpers; deduplicate the analysis arrow-flattening helpers. https://github.com/rescript-lang/rescript/pull/8569
