Claude Code

2.1.136

  • Added CLAUDE_CODE_ENABLE_FEEDBACK_SURVEY_FOR_OTEL to re-enable the session quality survey for enterprises capturing responses through OpenTelemetry

  • Added settings.autoMode.hard_deny for auto mode classifier rules that block unconditionally regardless of user intent or allow exceptions

  • Fixed MCP servers configured in .mcp.json, plugins, and claude.ai connectors silently disappearing after /clear in the VS Code extension, JetBrains plugin, and Agent SDK

  • Fixed a rare login loop where a concurrent credential write could overwrite a freshly-rotated OAuth token and force re-login

  • Fixed MCP OAuth refresh tokens being lost when multiple servers refresh concurrently — users with several remote MCP servers should no longer need daily re-authentication

  • Fixed --resume / --continue not finding sessions when the project path contains underscores

  • Fixed plan mode not blocking file writes when a matching Edit(...) allow rule exists

  • Fixed plugin Stop/UserPromptSubmit hooks failing when cache cleanup deletes a version still in use by a running session

  • Improved visual consistency across slash command dialogs: standardized footer hints, dialog spacing, and arrow-key styling, and the dialog frame now appears immediately during loading instead of popping in after

  • Fixed colors appearing at wrong positions in bash command output and markdown code blocks

  • Fixed ReasonML diffs rendering corrupted "undefined" text artifacts at word-diff boundaries

  • Fixed worktree exit dialog warning about uncommitted files in the wrong directory after worktree removal

  • Fixed @ file picker not matching files created mid-session in small non-git directories

  • Fixed @-mention file picker not finding files in directories with more than 100 entries

  • Fixed failed tool calls not being click-to-expand in fullscreen mode when their output was truncated

  • Fixed Backspace and Ctrl+Backspace getting swapped after using Ctrl+G to open an external editor on terminals with persistent extended-key modes

  • Fixed /usage weekly reset showing time of day instead of the calendar date

  • Fixed welcome banner ellipsis causing column overflow on CJK terminals

  • Fixed /insights crash when session history contains tool calls with malformed input fields

  • Fixed a renderer crash when a tool's collapsibility classification changes mid-session

  • Fixed trailing whitespace in copied terminal output during streaming

  • Fixed plugin uninstall and enable/disable not matching slugs case-insensitively

  • Fixed tool error truncation marker showing a negative count for surrogate-pair strings

  • Fixed env vars from CLAUDE_ENV_FILE SessionStart hooks going stale after /resume or /clear

  • Fixed /branch saving a multi-line session title when given a pasted multi-line name

  • Fixed a stray leading space on the second line of wrapped text at the column boundary

  • Fixed AskUserQuestion discarding multi-select answers when supplied as an array

  • Fixed /clear not labeling the cleared session for /resume

  • Fixed CronList output missing qualifiers and the scheduled prompt

  • Fixed "Jump to bottom" overlay leaving color artifacts on CJK characters in fullscreen mode

  • Fixed mid-input slash command autocomplete not working after an initial slash command

  • Fixed scrolling to bottom re-engaging auto-follow with autoScrollEnabled: false

  • Fixed prompt suggestions being auto-submitted by Enter on an empty input instead of requiring Tab or arrow to accept

  • Fixed keyboard shortcut hints not reflecting rebound keys from keybindings.json

  • Fixed /settings language change being reverted on Escape after confirming

  • Fixed /terminal-setup only appearing in autocomplete on exact name match instead of partial prefixes

  • Fixed "Chat about this" on an AskUserQuestion dialog erasing the question text

  • Fixed MCP tool results being invisible when the server returns content blocks

  • Improved error message when --worktree collides with an existing or stale worktree

  • Changed plugin marketplace removal key to d (matching delete elsewhere) instead of r which collided with retry

Claude Code

2.1.133

  • Added worktree.baseRef setting (fresh | head) to choose whether --worktree, EnterWorktree, and agent-isolation worktrees branch from origin/ or local HEAD. Note: the default fresh changes EnterWorktree's base back to origin/ (it has been local HEAD since 2.1.128) — set worktree.baseRef: "head" to keep unpushed commits in new worktrees

  • Added sandbox.bwrapPath and sandbox.socatPath managed settings (Linux/WSL) to specify custom bubblewrap and socat binary locations

  • Added parentSettingsBehavior admin-tier key ('first-wins' | 'merge') to let admins opt SDK managedSettings (parent tier) into the policy merge

  • Hooks now receive the active effort level via the effort.level JSON input field and the $CLAUDE_EFFORT environment variable, and Bash tool commands can read $CLAUDE_EFFORT

  • Improved focus mode behavior

  • Improved memory usage by releasing warm-spare background workers under memory pressure

  • Fixed parallel sessions all dead-ending at 401 after a refresh-token race wiped shared credentials

  • Fixed Edit/Write allow rules scoped to a drive root (C:\) or POSIX / matching incorrectly and always prompting

  • Fixed an unhandled rejection (ECOMPROMISED) when a history or session-log file lock is compromised by clock skew or slow disk

  • Fixed pressing Esc during conversation compaction showing a spurious "Error compacting conversation" notification

  • Fixed HTTP(S)_PROXY / NO_PROXY / mTLS not being respected for the full MCP OAuth flow including discovery, dynamic client registration, token exchange, and token refresh

  • Fixed Read/Write/Edit being denied on mapped network drives passed via --add-dir / SDK additionalDirectories

  • Fixed Remote Control stop/interrupt from claude.ai not fully canceling the CLI session the same way local Esc does, causing queued messages to never advance after interrupting a stuck tool or prompt

  • Fixed /effort in one session unexpectedly changing the effort level of other concurrent sessions, and a related issue where an IDE effort change could be silently dropped

  • Fixed subagents not discovering project, user, or plugin skills via the Skill tool

  • claude --help now lists --remote-control alongside --remote-control-session-name-prefix

  • [VSCode] Fixed claudeCode.claudeProcessWrapper failing with "Unsupported platform" when the extension build doesn't bundle a Claude binary

Codex CLI Release: 0.129.0

New Features

  • The TUI now supports modal Vim editing in the composer, including /vim, default-mode config, and Vim-specific keymap contexts. (#18595)

  • TUI workflows are easier to resume and copy from with a redesigned resume/fork picker, raw scrollback mode, /ide context injection, and workspace-aware /diff. (#20065, #20819, #20294, #21001)

  • The status line can show theme-aware colors plus optional PR and branch-change summaries, and /keymap debug helps inspect terminal key events. (#19631, #20892, #20794)

  • Plugin management now supports workspace sharing, share access controls, source filtering, local share path tracking, marketplace removal/upgrades, remote bundle sync, and admin-disabled status handling. (#20278, #21124, #21419, #20560, #19843, #20478, #20268, #20298)

  • Hooks can be browsed and toggled from /hooks, can run before/after compaction, and can add PreToolUse context; Codex Apps auth and eligible MCP elicitations now surface through TUI/Guardian flows. (#19882, #19905, #20692, #19193, #19431)

  • Experimental goals are now discoverable, stay paused across resume unless the user opts back in, and show clearer validation and multi-day duration output. (#20083, #20790, #20746, #20558)

Bug Fixes

  • /copy works better in tmux, Alt+Enter and modified Delete/Backspace keys behave correctly, and Windows typing/paste latency was reduced. (#20207, #20535, #21058, #18914)

  • Large paste placeholders and Ctrl+C-stashed drafts now survive clear/editor workflows without corrupting draft history. (#21091, #21190, #21351, #21397)

  • TUI startup and accessibility were tightened by bounding terminal probes, clearing the first inline viewport render, and honoring animations = false for live rows. (#20654, #21450, #20564)

  • Linux sandbox startup is more reliable across older bwrap, slow mount probes, symlink-protected paths, and shared /tmp setups. (#20628, #20111, #21127, #21234)

  • Windows sandbox and exec policy now handle named pipes, ConPTY teardown, PowerShell-wrapped allow rules, worktree safe.directory, and unsafe Git options more reliably. (#20270, #20685, #20336, #21409, #21275)

  • Fixed custom CA login behind TLS-inspecting proxies, Bedrock runtime endpoint reporting, dangerous project config keys, heredoc redirect approval matching, and unbounded MCP/hook output growth. (#20676, #20275, #20098, #20113, #20260, #21069)

Documentation

  • Updated the embedded OpenAI Docs sample skill so API-key setup guidance stays aligned with other docs variants. (#21263)

  • Documented how generated git commit attribution is gated by codex_git_commit and configured in config.toml. (#21379)

  • Removed local-only planning/spec docs and redirected config docs toward the maintained external documentation surface. (#20896)

Chores

  • Linux releases now build, publish, bundle, and verify a standalone bwrap fallback for npm and DotSlash installs. (#21255, #21256, #21257, #21312, #21285)

  • Vendored Bubblewrap was updated to 0.11.2, including upstream security changes around setuid support. (#21389)

  • Windows Bazel CI now uses faster cross-compilation for tests, clippy, and release-build checks, and Bazel now runs sharded Rust integration tests. (#20585, #20701, #21057)

  • App-server and protocol internals were split and slimmed down, including transport extraction, protocol module decomposition, thread/message history moves, and tool-handler cleanup. (#20324, #20325, #20348, #20545, #21251, #21278, #21395)

  • Analytics and diagnostics coverage expanded for tool lifecycles, goals, plugin skills, thread sources, service tiers, and PR issue labeling. (#17089, #17090, #20799, #20923, #20949, #20969, #20893)

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

2.1.131

  • Fixed VS Code extension failing to activate on Windows due to a hardcoded build path in the bundled SDK (createRequire polyfill bug)

  • Fixed Mantle endpoint authentication failing with missing x-api-key header

Claude Code

2.1.129

  • Added --plugin-url flag to fetch a plugin .zip archive from a URL for the current session

  • Added CLAUDE_CODE_FORCE_SYNC_OUTPUT=1 env var to force-enable synchronized output on terminals that auto-detection misses (e.g. Emacs eat)

  • Added CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE: when set on Homebrew or WinGet installations, Claude Code runs the upgrade command in the background and prompts to restart

  • Plugin manifests: themes and monitors should now be declared under "experimental": { ... }. Top-level declarations still work but claude plugin validate will warn

  • Gateway /v1/models discovery for the /model picker is now opt-in via CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 (was automatic in 2.1.126–2.1.128)

  • Ctrl+R history picker now defaults to searching all prompts across all projects, matching pre-2.1.124 behavior. Press Ctrl+S to narrow to the current project or session

  • Third-party deployments (Bedrock, Vertex, Foundry, or ANTHROPIC_BASE_URL gateway) no longer see spinner tips pointing at first-party Anthropic surfaces

  • skillOverrides setting now works: off hides from model and /, user-invocable-only hides from model only, name-only collapses description

  • The claude_code.pull_request.count OTel metric now counts PRs/MRs created via MCP tools, not just shell commands

  • Policy refusal error messages now include the API Request ID for easier support debugging

  • Fixed API errors with unrecognized 400 status codes showing raw JSON instead of the underlying error message

  • Fixed /clear not resetting the terminal tab title after a conversation

  • Fixed session title chip from /rename disappearing while a permission or other dialog is active

  • Fixed agent panel below the prompt being hidden when subagents are running (regression in 2.1.122)

  • Fixed external-editor handoff (Ctrl+G) blanking the conversation history above the prompt

  • Fixed /context dumping its rendered ASCII visualization grid into the conversation, wasting ~1.6k tokens per call

  • Fixed /agents Library list arrow-key navigation: the highlighted agent now stays visible when the list exceeds the viewport

  • Fixed /branch success message not including the new branch's session id for /resume

  • Fixed bold headers with keycap/ZWJ/skin-tone emoji losing trailing characters in fullscreen mode

  • Fixed server-managed settings policy not applying for enterprise/team users whose stored OAuth credentials lacked the user:inference scope

  • Fixed OAuth refresh race after wake-from-sleep that could log out all running sessions

  • Fixed 1-hour prompt cache TTL being silently downgraded to 5 minutes

  • Fixed cache-miss warning appearing spuriously after /clear or compaction when changing /effort or /model

  • Fixed Bash(mkdir *), Bash(touch *) and similar allow rules not being honored for in-project paths

  • Fixed deniedMcpServers patterns with a *:// scheme wildcard not matching mixed-case hostnames

  • Fixed harmless WebSocket warning being logged as an error in --debug during voice mode

  • [VSCode] Fixed /clear not clearing the conversation context and displayed transcript

2.1.128

  • Bare /color (no args) now picks a random session color

  • /mcp now shows the tool count for connected servers and flags servers that connected with 0 tools

  • --plugin-dir now accepts .zip plugin archives in addition to directories

  • --channels now works with console (API key) authentication — console orgs with managed settings must set channelsEnabled: true to enable

  • Updated /model picker: collapsed duplicate Opus 4.7 entries, and current Opus now shows as "Opus" instead of "Opus 4.7"

  • Subprocesses (Bash, hooks, MCP, LSP) no longer inherit OTEL_* environment variables, so OTEL-instrumented apps run via the Bash tool no longer pick up the CLI's own OTLP endpoint

  • MCP: workspace is now a reserved server name — existing servers with that name will be skipped with a warning

  • Reconnecting MCP servers no longer flood the conversation with full tool-name lists on every reconnect — re-announced tools are summarized by server prefix

  • SDK hosts now receive a persistent localSettings suggestion for Bash permission prompts, so "Always allow" writes to .claude/settings.local.json

  • EnterWorktree now creates the new branch from local HEAD as documented, instead of origin/ — unpushed commits are no longer dropped

  • Auto mode: when the classifier can't evaluate an action, the error now includes a hint (retry, /compact, or run with --debug)

  • Fixed focus mode briefly dimming the previous response when submitting a new prompt

  • Fixed stray "4;0;" desktop notification on every /exit in Kitty and other terminals that interpret OSC 9 as a notification

  • Fixed Remote Control showing an empty "Opening your options…" message on rate limit instead of actionable upsell options

  • Fixed drag-and-drop image upload hanging on "Pasting text…" when the image read fails

  • Fixed crash loop when piping very large input (>10 MB) to claude -p via stdin

  • Fixed long URLs not being individually clickable on every wrapped row in fullscreen mode

  • Fixed /plugin Components panel showing "Marketplace 'inline' not found" for plugins loaded via --plugin-dir

  • Fixed MCP tool results dropping images when the server returns both structured content and content blocks

  • Fixed fenced code blocks inside list items carrying leading whitespace into the clipboard on copy-paste

  • Fixed tab navigation in /config stranding focus — the tab header now stays focused so arrows and Esc keep working

  • Fixed markdown link labels being lost on terminals without OSC 8 hyperlink support — links now render as label (url) instead of just the URL

  • Fixed sessions on 1M-context models with a smaller autocompact window being falsely blocked with "Prompt is too long" before reaching the actual API limit

  • Fixed parallel shell tool calls: a failing read-only command (grep, git diff, ls) no longer cancels sibling calls

  • Fixed banner showing "with X effort" on models that don't support effort

  • Fixed /fast on 3P providers fuzzy-matching to an unrelated skill instead of showing "not available"

  • Fixed Bedrock default model resolving to global.* instead of the region-appropriate prefix

  • Fixed vim mode: Space in NORMAL mode now moves the cursor right, matching standard vi/vim behavior

  • Fixed terminal progress indicator (OSC 9;4) flickering off between tool calls — stays visible across the full turn

  • Fixed /rename without args failing on resumed sessions whose last entry is a compact boundary

  • Fixed stale "remote-control is active" status lines from prior sessions appearing after --resume/--continue

  • Fixed stale installed_plugins.json entries pointing at deleted cache directories polluting PATH

  • Fixed MCP stdio servers receiving corrupted arguments when CLAUDE_CODE_SHELL_PREFIX is set and an argument contains spaces or shell metacharacters

  • Fixed sub-agent progress summaries missing the prompt cache (~3× cache_creation reduction)

  • Fixed /plugin update never detecting new versions of npm-sourced plugins

  • Fixed sub-agent summaries firing repeatedly while a sub-agent's transcript is static, capping worst-case token cost on idle sub-agents

  • Headless --output-format stream-json: init.plugin_errors now includes --plugin-dir load failures in addition to dependency demotions
