Major Changes

• bd2a46a: WyW-in-JS packages are now ESM-only and require Node.js >= 22.0.0.

  Breaking changes in v2:

  • CJS require() package entrypoints were removed; migrate configs/tooling to ESM (import() / .mjs).
  • Eval moved to the async ESM runner-based pipeline (vm.SourceTextModule + broker RPC), which is now the default path in v2.
  • Eval IPC and Babel preset config handling are stricter:
    • unsupported values in __wywPreval now fail explicitly instead of being silently coerced through JSON
    • function-valued preset/plugin options are supported when loaded from config files, while inline non-serializable options now error with migration guidance
    • eval.globals encoding and invalidation are more predictable and reject unsupported values earlier
  • require() inside eval now follows fallback semantics controlled by eval.require (warn-and-run / error / off).

  This release also updates the published bundler integrations, adapter coverage,
  and migration/docs around the v2 evaluator contract, and includes cache and
  warm-runner reuse fixes to keep the new evaluator on the expected performance
  path.

• d553b68: Complete the v2 Oxc migration across the core transform and evaluator pipeline.

  This cutover moves the runtime transform path to the Oxc-backed implementation, including module analysis, preeval rewrites, dangerous-code removal, processor application, template dependency extraction, shaker, collect, emit, and the async ESM evaluator flow.

  The public configuration contract is now Oxc-first, with oxcOptions, EvalRule.oxcOptions, and the hybrid resolver mode available across the updated packages. Processor integrations now rely on the engine-neutral AstService surface, and the migration includes cache, concurrency, and hot-path performance fixes needed to keep downstream behavior stable after the cutover. @wyw-in-js/babel-preset stays available only as a deprecated compatibility wrapper around the Oxc pipeline.
