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

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
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
