NotesSection of the release

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.
Evidence

Import changes visible across the diff header; verified via counts of tengu_ flags (933 each), CLAUDE_CODE_ env vars (399 each), .describe( settings (385 each), slash commands (1,128 each), and CLI flags (129 unique each) — all identical between v2.1.55 and v2.1.56.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
