Claude Code v2.1.132: Enhanced Terminal Experience and Improved Stability

Claude Code v2.1.132 has arrived with a comprehensive set of improvements focused on enhancing the terminal experience and resolving critical stability issues. This release introduces new environment variables for better session control and addresses numerous edge cases that have been affecting power users.

What’s New

New Environment Variables

Session ID Access: The new CLAUDE_CODE_SESSION_ID environment variable is now available in the Bash tool subprocess environment, providing consistency with the session_id passed to hooks. This enables better session tracking and custom integrations.

Alternate Screen Control: Users can now set CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1 to opt out of the fullscreen alternate-screen renderer, keeping conversations in the terminal’s native scrollback. This is particularly useful for users who prefer traditional terminal behavior.

Enhanced User Experience

Visual Feedback: A new “Pasting…” footer hint appears during Ctrl+V image paste operations, providing clear feedback when clipboard operations are in progress.

Improved Signal Handling: External SIGINT signals (from IDE stop buttons or kill -INT commands) now trigger graceful shutdowns instead of abrupt exits, properly restoring terminal modes and displaying the --resume hint.

Critical Bug Fixes

Unicode and Text Handling: This release resolves several Unicode-related issues, including:

Fixed emoji corruption during tool error truncation that could break --resume functionality
Improved cursor positioning with Indic conjuncts and ZWJ emojis
Resolved vim operators corrupting decomposed (NFD) accented characters

Terminal Compatibility: Enhanced compatibility across different terminal environments:

Fixed scroll wheel speed issues in Cursor and VS Code terminals
Improved JetBrains IDE 2025.2 terminal support
Resolved Windows Terminal contradictory error messages

Session Management: Several session-related improvements including:

Fixed --permission-mode flag handling during session resumption
Resolved fullscreen mode display issues after system sleep/wake
Improved paste handling for commands starting with /

MCP Server Improvements: Better error handling and memory management for MCP servers, including fixes for unbounded memory growth and improved connection retry logic.
