Summary

Claude Code v2.1.132 shipped 26 fixes and 4 new features. The new additions include CLAUDE_CODE_SESSION_ID injected into Bash subprocess environments (enabling hooks to correlate with sessions), CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1 for opting out of the fullscreen renderer, and a clipboard paste hint. The bulk of the release addresses terminal compatibility — cursor handling, Indic/ZWJ emoji edge cases, JetBrains 2025.2 scroll bugs, and VS Code 1.92–1.104 mouse-wheel issues — plus a critical fix for unbounded memory growth (10GB+ RSS) when a stdio MCP server writes non-protocol data to stdout.

Implications

• Feeds the Claude Code reliability thread: the MCP memory leak fix is operationally significant for anyone running long sessions with stdio MCP servers; 10GB+ RSS is a session-killing regression.
• CLAUDE_CODE_SESSION_ID in subprocess env strengthens the hooks/automation integration surface — agents can now correlate Bash tool calls to parent sessions without parsing logs.
• Terminal compatibility breadth (JetBrains, VS Code, iTerm2, Windows Terminal) signals Claude Code is being hardened for enterprise developer environments, not just personal terminal setups.
