Claude Code stable is still on 2.1.231 — nine releases behind latest, missing two billing fixes.
npm @anthropic-ai/claude-code dist-tags this morning: stable → 2.1.231, latest/next → 2.1.241.1 2.1.239 (21 Aug) fixed Bedrock behind proxies that strip response Content-Type: every turn silently re-ran non-streaming and doubled the bill.2 2.1.237 fixed prompt caching through LLM gateways / custom base URLs.3 Both are above stable.
Docs: stable is typically about a week behind; Homebrew claude-code tracks stable, claude-code@latest tracks latest; package-manager installs do not auto-update.4 Native latest already has the fixes.
On Bedrock or a gateway: install ≥2.1.239 (or set minimumVersion 2.1.239 on stable). Confirm with claude --version. Others can wait for stable.
