 # Changelog
 
+## 2.1.132
+
+- 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
