v2.1.238: subtle but impactful ops improvements—memory leak fix and Remote Control stability gains make production deployment smoother.
Claude Code v2.1.238 released with keybinding customization, proxy auth, and bug fixes
Original: v2.1.238
Importance: マイナーバージョン更新で既存ユーザーに実装影響は限定的だが、長時間運用のメモリリーク修正とRemote Control安定性向上は運用環境への部分的な改善。
Summary
Claude Code v2.1.238 is released with improvements including readline-style keybinding option (Ctrl+W deletes to previous whitespace), plugin marketplace headersHelper for dynamic HTTP headers, self-hosted-runner shutdown and proxy auth controls, and extensive bug fixes. Notable fixes: unbounded memory growth in long sessions, custom output styles drifting to defaults, Remote Control reconnection and model pick synchronization issues, MCP server initialization order, terminal rendering with emoji/tabs, and SSH/mosh keystroke buffering.
Key Points
- keybindingFlavor option enables readline-compatible Ctrl+W behavior
- Self-hosted runner gains shutdown control and proxy auth support
- Unbounded memory growth in long sessions resolved
- Remote Control reconnection, model sync, and crash recovery improved
- MCP initialization order and terminal rendering bugs fixed
View developer notes (APIs, breaking changes, migration)
v2.1.238 adds operational control: `--defer-shutdown-max-min <minutes>` for graceful self-hosted-runner shutdown handling SIGTERM with attached session preservation. Proxy auth support via `--proxy-authorization-command`/`--proxy-authorization-file` for egress proxies requiring fresh headers per connection. Memory leak fixed by releasing subagent tool results after display window. MCP fix: `server/discover` now sent after `initialize` to prevent lazy backend startup on every session. Remote Control improvements: process crash recovery without restart, model pick sync across web/desktop/phone, network hiccup resilience with retry logic, sign-out clarity. ListAgents/SendMessage now exclude idle worker pool exposure from Remote Control peers.
