Version 2.1.56

Version 2.1.56 is a maintenance release with internal refactoring only. The bundler output was updated to use named/destructured imports for Node.js core modules instead of default imports, simplifying several lazy initialization wrappers. There are no user-facing changes in this release.

Notes

2 items

This release contains no new features, improvements, or bug fixes that affect users. The 99.9% structural similarity between v2.1.55 and v2.1.56 reflects purely internal changes:

  • Import modernization: Default imports like import X from "child_process" were replaced with named imports like import { execFile, spawn } from "child_process" across 12 Node.js core modules (child_process, crypto, https, node:child_process, node:fs, node:os, node:path, node:process, node:util, path, stream, url).
  • Initialization simplification: Several lazy initialization wrappers (e.g., for promisify(execFile)) were simplified or removed since named imports no longer require runtime extraction from default import objects.
