2026-03-16

  • +Added allowRead sandbox filesystem setting to re-allow read access within `denyRead` regions
  • ~Increased default maximum output token limits for Claude Opus 4.6 to 64k tokens, and the upper bound for Opus 4.6 and Sonnet 4.6 models to 128k tokens
  • ~/copy now accepts an optional index: `/copy N` copies the Nth-latest assistant response
+ 41 more− less
full release →
  • ~Background bash tasks are now killed if output exceeds 5GB, preventing runaway processes from filling disk
  • ~Sessions are now auto-named from plan content when you accept a plan
  • ~Show a notice when apiKeyHelper takes longer than 10s, preventing it from blocking the main loop
  • ~The Agent tool no longer accepts a `resume` parameter — use `SendMessage({to: agentId})` to continue a previously spawned agent
  • ~SendMessage now auto-resumes stopped agents in the background instead of returning an error
  • ~Renamed /fork to `/branch` (`/fork` still works as an alias)
  • ~VSCodeWhen option+click doesn't trigger native selection on macOS, the footer now points to the `macOptionClickForcesSelection` setting
  • ↑Faster startup on macOS (~60ms) by reading keychain credentials in parallel with module loading
  • ↑Faster --resume on fork-heavy and very large sessions — up to 45% faster loading and ~100-150MB less peak memory
  • ↑Improved Esc to abort in-flight non-streaming API requests
  • ↑Improved claude plugin validate to check skill, agent, and command frontmatter plus `hooks/hooks.json`, catching YAML parse errors and schema violations

  • ↑VSCodeImproved plan preview tab titles to use the plan's heading instead of "Claude's Plan"
  • ✓Fixed "Always Allow" on compound bash commands (e.g. `cd src && npm test`) saving a single rule for the full string instead of per-subcommand, leading to dead rules and repeated permission prompts
  • ✓Fixed auto-updater starting overlapping binary downloads when the slash-command overlay repeatedly opened and closed, accumulating tens of gigabytes of memory
  • ✓Fixed --resume silently truncating recent conversation history due to a race between memory-extraction writes and the main transcript
  • ✓Fixed PreToolUse hooks returning `"allow"` bypassing `deny` permission rules, including enterprise managed settings
  • ✓Fixed Write tool silently converting line endings when overwriting CRLF files or creating files in CRLF directories
  • ✓Fixed memory growth in long-running sessions from progress messages surviving compaction
  • ✓Fixed cost and token usage not being tracked when the API falls back to non-streaming mode
  • ✓Fixed CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS not stripping beta tool-schema fields, causing proxy gateways to reject requests

  • ↑Improved background agent behavior — killing a background agent now preserves its partial results in the conversation context
  • ↑Improved model fallback notifications — now always visible instead of hidden behind verbose mode, with human-friendly model names
  • ↑Improved blockquote readability on dark terminal themes — text is now italic with a left bar instead of dim
  • ↑Improved stale worktree cleanup — worktrees left behind after an interrupted parallel run are now automatically cleaned up
  • ↑Improved Remote Control session titles — now derived from your first prompt instead of showing "Interactive session"
  • ↑Improved /voice to show your dictation language on enable and warn when your `language` setting isn't supported for voice input
  • ✓Fixed deferred tools (loaded via `ToolSearch`) losing their input schemas after conversation compaction, causing array and number parameters to be rejected with type errors
  • ✓Fixed slash commands showing "Unknown skill"

  • +Added actionable suggestions to `/context` command — identifies context-heavy tools, memory bloat, and capacity warnings with specific optimization tips
  • +Added autoMemoryDirectory setting to configure a custom directory for auto-memory storage
  • ~Changed --plugin-dir so local dev copies now override installed marketplace plugins with the same name (unless that plugin is force-enabled by managed settings)
+ 14 more− less
full release →
  • ↑VSCodeImproved scroll wheel responsiveness in the integrated terminal with terminal-aware acceleration
  • ✓Fixed memory leak where streaming API response buffers were not released when the generator was terminated early, causing unbounded RSS growth on the Node.js/npm code path
  • ✓Fixed managed policy ask rules being bypassed by user `allow` rules or skill `allowed-tools`
  • ✓Fixed full model IDs (e.g., claude-opus-4-5) being silently ignored in agent frontmatter `model:` field and `--agents` JSON config — agents now accept the same model values as `--model`
  • ✓Fixed MCP OAuth authentication hanging when the callback port is already in use
  • ✓Fixed MCP OAuth refresh never prompting for re-auth after the refresh token expires, for OAuth servers that return errors with HTTP 200 (e.g. Slack)
  • ✓Fixed voice mode silently failing on the macOS native binary for users whose terminal had never been granted microphone permission — the binary now includes the `audio-input` entitlement so macOS prompts correctly
  • ✓Fixed SessionEnd hooks being killed after 1.5 s on exit regardless of `hook.timeout` — now configurable via `CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS`
  • ✓Fixed /plugin install failing inside the REPL for marketplace plugins with local sources
5 more fixed on the release page →
  • +Added modelOverrides setting to map model picker entries to custom provider model IDs (e.g. Bedrock inference profile ARNs)
  • +Added actionable guidance when OAuth login or connectivity checks fail due to SSL certificate errors (corporate proxies, `NODE_EXTRA_CA_CERTS`)
  • ~Changed default Opus model on Bedrock, Vertex, and Microsoft Foundry to Opus 4.6 (was Opus 4.1)
+ 23 more− less
full release →
  • −Deprecated /output-style command — use `/config` instead. Output style is now fixed at session start for better prompt caching

  • +Added ExitWorktree tool to leave an `EnterWorktree` session
+ 48 more− less
full release →
  • +Added CLAUDE_CODE_DISABLE_CRON environment variable to immediately stop scheduled cron jobs mid-session

  • +Added support for marketplace git URLs without `.git` suffix (Azure DevOps, AWS CodeCommit)
  • +VSCodeAdded effort level indicator on the input border
  • +VSCodeAdded vscode://anthropic.claude-code/open URI handler to open a new Claude Code tab programmatically, with optional `prompt` and `session` query parameters
  • ~Restored the model parameter on the Agent tool for per-invocation model overrides
  • ~Simplified effort levels to low/medium/high (removed max) with new symbols (○ ◐ ●) and a brief notification instead of a persistent icon. Use `/effort auto` to reset to default
  • ~Changed CLAUDE.md HTML comments (`<!-- ... -->`) to be hidden from Claude when auto-injected. Comments remain visible when read with the Read tool
  • ↑Improved /config — Escape now cancels changes, Enter saves and closes, Space toggles settings
  • ↑Improved up-arrow history to show current session's messages first when running multiple concurrent sessions
  • ↑Improved voice input transcription accuracy for repo names and common dev terms (regex, OAuth, JSON)
  • ↑Improved bash command parsing by switching to a native module — faster initialization and no memory leak
  • ↑Reduced bundle size by ~510 KB
  • ↑Improved marketplace clone failure messages to show diagnostic info even when git produces no stderr

2026-03-06

  • +Added /loop command to run a prompt or slash command on a recurring interval (e.g. `/loop 5m check the deploy`)
  • +Added cron scheduling tools for recurring prompts within a session
  • +Added voice:pushToTalk keybinding to make the voice activation key rebindable in `keybindings.json` (default: space) — modifier+letter combos like `meta+k` have zero typing interference
+ 25 more− less
full release →
  • +Added fmt, `comm`, `cmp`, `numfmt`, `expr`, `test`, `printf`, `getconf`, `seq`, `tsort`, and `pr` to the bash auto-approval allowlist
  • ~Updated /debug to toggle debug logging on mid-session, since debug logs are no longer written by default
  • −Removed startup notification noise for unauthenticated org-registered claude.ai connectors
  • ↑Improved startup time by deferring native image processor loading to first use
  • ↑Improved bridge session reconnection to complete within seconds after laptop wake from sleep, instead of waiting up to 10 minutes
  • ↑Improved /plugin uninstall to disable project-scoped plugins in `.claude/settings.local.json` instead of modifying `.claude/settings.json`, so changes don't affect teammates
  • ↑Improved plugin-provided MCP server deduplication — servers that duplicate a manually-configured server (same command/URL) are now skipped, preventing duplicate connections and tool sets. Suppressions are shown in the `/plugin` menu.
  • ✓Fixed stdin freeze in long-running sessions where keystrokes stop being processed but the process stays alive
  • ✓Fixed a 5–8 second startup freeze for users with voice mode enabled, caused by CoreAudio initialization blocking the main thread after system wake
  • ✓Fixed startup UI freeze when many claude.ai proxy connectors refresh an expired OAuth token simultaneously
  • ✓Fixed forked conversations (/fork) sharing the same plan file, which caused plan edits in one fork to overwrite the other
  • ✓Fixed the Read tool putting oversized images into context when image processing failed, breaking subsequent turns in long image-heavy sessions
  • ✓Fixed false-positive permission prompts for compound bash commands containing heredoc commit messages
  • ✓Fixed plugin installations being lost when running multiple Claude Code instances
  • ✓Fixed claude.ai connectors failing to reconnect after OAuth token refresh

+ 26 more− less
full release →
  • ↑Improved error message when microphone captures silence to distinguish from "no speech detected"
  • ↑Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction
  • ↑Improved /rename to work while Claude is processing, instead of being silently queued
  • ↑Reduced prompt input re-renders during turns by ~74%
  • ↑Reduced startup memory by ~426KB for users without custom CA certificates
  • ↑Reduced Remote Control /poll rate to once per 10 minutes while connected (was 1–2s), cutting server load ~300×. Reconnection is unaffected — transport loss immediately wakes fast polling.
  • ✓Fixed API 400 errors when using `ANTHROPIC_BASE_URL` with a third-party gateway — tool search now correctly detects proxy endpoints and disables `tool_reference` blocks
  • ✓Fixed API Error: 400 This model does not support the effort parameter when using custom Bedrock inference profiles or other model identifiers not matching standard Claude naming patterns
  • ✓Fixed empty model responses immediately after `ToolSearch` — the server renders tool schemas with system-prompt-style tags at the prompt tail, which could confuse models into stopping early
  • ✓Fixed prompt-cache bust when an MCP server with `instructions` connects after the first turn
  • ✓Fixed Enter inserting a newline instead of submitting when typing over a slow SSH connection
  • ✓Fixed clipboard corrupting non-ASCII text (CJK, emoji) on Windows/WSL by using PowerShell `Set-Clipboard`
  • ✓Fixed extra VS Code windows opening at startup on Windows when running from the VS Code integrated terminal
  • ✓Fixed voice mode failing on Windows native binary with "native audio module could not be loaded"

+ 100 more− less
full release →
  • +Added optional name argument to `/remote-control` and `claude remote-control` (`/remote-control My Project` or `--name "My Project"`) to set a custom session title visible in claude.ai/code
  • +Added Voice STT support for 10 new languages (20 total) — Russian, Polish, Turkish, Dutch, Ukrainian, Greek, Czech, Danish, Swedish, Norwegian
  • +Added effort level display (e.g., "with low effort") to the logo and spinner, making it easier to see which effort setting is active
  • +Added agent name display in terminal title when using `claude --agent`
  • +Added sandbox.enableWeakerNetworkIsolation setting (macOS only) to allow Go programs like `gh`, `gcloud`, and `terraform` to verify TLS certificates when using a custom MITM proxy with `httpProxyPort`

  • +Added /reload-plugins command to activate pending plugin changes without restarting
  • +Added a one-time startup prompt suggesting Claude Code Desktop on macOS and Windows (max 3 showings, dismissible)
10 more new on the release page →
  • ~Changed Sonnet 4.5 users on Pro/Max/Team Premium to be automatically migrated to Sonnet 4.6
  • ~Changed the /resume picker to show your most recent prompt instead of the first one. This also resolves some titles appearing as `(session)`.
  • ~Changed claude.ai MCP connector failures to show a notification instead of silently disappearing from the tool list
  • ~Changed example command suggestions to be generated deterministically instead of calling Haiku
  • ~Changed resuming after compaction to no longer produce a preamble recap before continuing
  • ~SDKChanged task creation to no longer require the `activeForm` field — the spinner falls back to the task subject
  • ~VSCodeThe permission mode picker now respects `permissions.disableBypassPermissionsMode` from your effective Claude Code settings (including managed/policy settings) — when set to `disable`, bypass permissions mode is hidden from the picker
  • ↑Improved spinner performance by isolating the 50ms animation loop from the surrounding shell, reducing render and CPU overhead during turns
  • ↑Improved UI rendering performance in native binaries with React Compiler
  • ↑Improved --worktree startup by eliminating a git subprocess on the startup path
  • ↑Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve
  • ↑Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup
  • ↑Improved MCP -p startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching
  • ↑Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter
  • ↑Improved MCP binary content handling: tools returning PDFs, Office documents, or audio now save decoded bytes to disk with the correct file extension instead of dumping raw base64 into the conversation context. WebFetch also saves binary responses alongside its summary.

  • ✓Fixed a security issue where nested skill discovery could load skills from gitignored directories like `node_modules`
  • ✓Fixed trust dialog silently enabling all `.mcp.json` servers on first run. You'll now see the per-server approval dialog as expected
  • ✓Fixed claude remote-control crashing immediately on npm installs with "bad option: --sdk-url" (anthropics/claude-code#28334)
  • ✓Fixed --model claude-opus-4-0 and `--model claude-opus-4-1` resolving to deprecated Opus versions instead of current
  • ✓Fixed macOS keychain corruption when using multiple OAuth MCP servers. Large OAuth metadata blobs could overflow the `security -i` stdin buffer, silently leaving stale credentials behind and causing repeated `/login` prompts.
  • ✓Fixed .credentials.json losing `subscriptionType` (showing "Claude API" instead of "Claude Pro"/"Claude Max") when the profile endpoint transiently fails during token refresh (anthropics/claude-code#30185)
  • ✓Fixed ghost dotfiles (.bashrc, `HEAD`, etc.) appearing as untracked files in the working directory after sandboxed Bash commands on Linux
  • ✓Fixed Shift+Enter printing [27;2;13~ instead of inserting a newline in Ghostty over SSH
50 more fixed on the release page →
  • ~Opus 4.6 now defaults to medium effort for Max and Team subscribers. Medium effort works well for most tasks — it's the sweet spot between speed and thoroughness. You can change this anytime with `/model`
  • ~Re-introduced the "ultrathink" keyword to enable high effort for the next turn
  • −Removed Opus 4 and 4.1 from Claude Code on the first-party API — users with these models pinned are automatically moved to Opus 4.6

  • +Added /copy command to show an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response.
  • ~Claude automatically saves useful context to auto-memory. Manage with /memory
  • ↑Improved "always allow" prefix suggestions for compound bash commands (e.g. `cd /tmp && git fetch && git push`) to compute smarter per-subcommand prefixes instead of treating the whole command as one
