Claude Code version 2.1.238 introduces several new features and fixes, including a configurable keybinding flavor for the prompt interface and support for minting HTTP headers in plugin marketplaces.
- Added `keybindingFlavor` setting to allow "readline" style Ctrl+W behavior in the prompt.
- Plugin marketplaces can now use `headersHelper` to mint short-lived tokens for catalog fetches.
- New `--defer-shutdown-max-min` and proxy authorization options improve self-hosted runner control.
- Fixed unbounded memory growth by releasing subagent tool results outside the recent display window.
- Improved Remote Control resilience with retries for brief network hiccups and better session reuse.
- Cross-session messaging now reports refused or dropped messages instead of failing silently.
These changes enhance configuration flexibility, plugin security, and stability for long-running sessions and remote control workflows.
