2.1.132 — Claude code - Product release notes & changelog tool

Added CLAUDE_CODE_SESSION_ID environment variable to the Bash tool subprocess environment, matching the session_id passed to hooks
Added CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1 env var to opt out of the fullscreen alternate-screen renderer and keep the conversation in the terminal’s native scrollback
Added a “Pasting…” footer hint while a Ctrl+V image paste is being read from the clipboard
Fixed external SIGINT (e.g. IDE stop button, kill -INT) not running graceful shutdown — terminal modes are now restored and the --resume hint is printed instead of an abrupt exit
Fixed an uncaught exception when the terminal is closed or SSH disconnects mid-session under the native build
Fixed --resume failing with no low surrogate in string when a tool error truncation split an emoji; pre-corrupted sessions are sanitized on load
Fixed --permission-mode flag being ignored when resuming a plan-mode session with -p --continue/--resume, and plan mode not being re-applied after ExitPlanMode within the same session
Fixed fullscreen mode showing a blank screen after laptop sleep/wake or Ctrl+Z/fg until the next keystroke or stream output
Fixed cursor landing mid-grapheme on Ctrl+E/A/K/U/arrow keys when an Indic conjunct or ZWJ emoji wraps across lines
Fixed vim operators corrupting text containing decomposed (NFD) accented characters
Fixed pasting text starting with / silently swallowing the input or triggering an unknown-command reply
Fixed pasting dumping stray escape sequences into the prompt when focus events or mouse-tracking reports interleave with the bracketed paste
Fixed mouse wheel scrolling being too fast in Cursor and VS Code 1.92–1.104 due to an upstream xterm.js bug
Fixed scroll-wheel handling in JetBrains IDE 2025.2 terminals (spurious arrow keys, wrong-direction events, runaway acceleration)
Fixed /usage Ctrl+S hanging when copying the stats screenshot to the clipboard on Linux/X11
Fixed /terminal-setup showing a contradictory error in Windows Terminal — Shift+Enter is natively supported there
Fixed /effort picker not reflecting the CLAUDE_CODE_EFFORT_LEVEL env var override
Fixed /status showing the wrong default model for some users
Fixed slash command autocomplete popup being capped at ~3–5 visible commands instead of scaling with terminal height
Fixed statusline context_window token counts reflecting cumulative session totals instead of current context usage
Fixed Alt+T (thinking toggle) not working on macOS terminals without “Option as Meta” enabled (iTerm2, Terminal.app defaults)
Fixed dead keyboard input on Windows after re-opening a background session from claude agents
Fixed unbounded memory growth (10GB+ RSS) when a stdio MCP server writes non-protocol data to stdout
Fixed MCP servers that connect but fail tools/list silently showing 0 tools — they now retry once and show “connected · tools fetch failed” in /mcp
Fixed unauthorized claude.ai MCP connectors showing as “failed” instead of “needs auth”, and headless -p mode retrying non-transient 4xx connection failures
Improved visual consistency in slash command dialogs and /login, /upgrade, /extra-usage dialog spacing
Updated the /tui fullscreen startup banner to describe additional renderer benefits (lower memory usage, mouse support, auto-copy on select)
Fixed Bedrock and Vertex 400 errors when ENABLE_PROMPT_CACHING_1H is set
