Claude Code v2.1.43: Three Fixes, Recorded but Never Published

Not installable. v2.1.43 is recorded in the official changelog, but @anthropic-ai/claude-code has no 2.1.43 on npm and the repository has no v2.1.43 tag. v2.1.42 shipped on 2026-02-13 and v2.1.44 on 2026-02-16. The three entries below are what the changelog records; they reached users in a later release.

Claude Code v2.1.43 has three changelog entries, all fixes.

What’s New

  • AWS auth refresh no longer hangs indefinitely — a three-minute timeout was added.
  • Spurious warnings are gone for non-agent markdown files in the .claude/agents/ directory.
  • The structured-outputs beta header is no longer sent unconditionally on Vertex and Bedrock.

How to Update

  1. Check your installed version: claude --version
  2. Update in place: claude update

There is no 2.1.43 to install; claude update moves you to the current release.
