[Release] anthropics/claude-code v2.1.234: v2.1.234

Claude Code v2.1.234 introduces environment variable configuration for project directories, GitLab merge request integration, automatic session continuation at usage limits, and significant security hardening against Windows NT-namespace path exploits. The release includes numerous bug fixes for session management, permission handling, markdown rendering, and Remote Control functionality, plus UX improvements for fullscreen mode and mid-turn command execution.

Key Points

• •Added `CLAUDE_CODE_PROJECT_DIR_NAME` environment variable for custom per-project transcript directory naming
• •Implemented `selection:clear` keybinding action to clear in-app text selections across views
• •Added GitLab merge request badge showing MR status (draft/pending/green) in footer and statusline
• •Automatic session continuation when Claude.ai usage limits reset (configurable in `/config`)
• •Security hardening: reject Windows NT-namespace (`\?\`) paths in file reads, session restore, CLAUDE.md includes, workflow scripts, and uploads to prevent NTLM credential-leak exploits
• •Fixed auto mode network access re-checking in long sessions after conversation compaction
• •Fixed session-scoped permission answers being dropped during background subagent tool prompts
• •Improved `/permissions` dialog to open mid-turn with rule changes applying to current turn
• •Fixed Remote Control sessions to properly sync permission mode and effort level across devices
• •Reduced context cost of built-in `claude-api` skill from ~200k to ~25k tokens via on-demand reference loading
