Anthropic's agentic coding tool for developers.

Update Jun 4, 2026 tracked by Updatify

2.1.86

  • Added .jj and .sl to VCS directory exclusion lists so Grep and file autocomplete don’t descend into Jujutsu or Sapling metadata
  • Fixed --resume failing with “tool_use ids were found without tool_result blocks” on sessions created before v2.1.85
  • Fixed Write/Edit/Read failing on files outside the project root (e.g., ~/.claude/CLAUDE.md) when conditional skills or rules are configured
  • Fixed unnecessary config disk writes on every skill invocation that could cause performance issues and config corruption on Windows
  • Fixed potential out-of-memory crash when using /feedback on very long sessions with large transcript files
  • Fixed --bare mode dropping MCP tools in interactive sessions and silently discarding messages enqueued mid-turn
  • Fixed the c shortcut copying only ~20 characters of the OAuth login URL instead of the full URL
  • Fixed masked input (e.g., OAuth code paste) leaking the start of the token when wrapping across multiple lines on narrow terminals
  • Fixed official marketplace plugin scripts failing with “Permission denied” on macOS/Linux since v2.1.83

  • Plugins blocked by organization policy (managed-settings.json) can no longer be installed or enabled, and are hidden from marketplace views
  • PreToolUse hooks can now satisfy AskUserQuestion by returning updatedInput alongside permissionDecision: "allow", enabling headless integrations that collect answers via their own UI
  • tool_parameters in OpenTelemetry tool_result events are now gated behind OTEL_LOG_TOOL_DETAILS=1
  • Fixed /compact failing with “context exceeded” when the conversation has grown too large for the compact request itself to fit
  • Fixed /plugin enable and /plugin disable failing when a plugin’s install location differs from where it’s declared in settings

  • /copy now accepts an optional index: /copy N copies the Nth-latest assistant response
  • 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

Update Jun 4, 2026 tracked by Updatify

2.1.74

  • 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
  • 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

Update Jun 4, 2026 tracked by Updatify

2.1.72

  • Fixed tool search to activate even with ANTHROPIC_BASE_URL as long as ENABLE_TOOL_SEARCH is set.
  • Added w key in /copy to write the focused selection directly to a file, bypassing the clipboard (useful over SSH)
  • Added optional description argument to /plan (e.g., /plan fix the auth bug) that enters plan mode and immediately starts
  • Added ExitWorktree tool to leave an EnterWorktree session
  • Added CLAUDE_CODE_DISABLE_CRON environment variable to immediately stop scheduled cron jobs mid-session

Update Jun 4, 2026 tracked by Updatify

2.1.71

  • 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
  • Added fmt, comm, cmp, numfmt, expr, test, printf, getconf, seq, tsort, and pr to the bash auto-approval allowlist
  • Fixed stdin freeze in long-running sessions where keystrokes stop being processed but the process stays alive

  • 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

Update Jun 4, 2026 tracked by Updatify

2.1.70

  • 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

Update Jun 4, 2026 tracked by Updatify

2.1.68

  • 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

Update Jun 4, 2026 tracked by Updatify

2.1.53

  • Fixed a UI flicker where user input would briefly disappear after submission before the message rendered

  • Fixed graceful shutdown sometimes leaving stale sessions when using Remote Control by parallelizing teardown network calls
  • Fixed --worktree sometimes being ignored on first launch
  • Fixed a panic (“switch on corrupted value”) on Windows

Update Jun 4, 2026 tracked by Updatify

2.1.51

  • Added claude remote-control subcommand for external builds, enabling local environment serving for all users.
  • Updated plugin marketplace default git timeout from 30s to 120s and added CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS to configure.
  • Added support for custom npm registries and specific version pinning when installing plugins from npm sources
  • BashTool now skips login shell (-l flag) by default when a shell snapshot is available, improving command execution performance. Previously this required setting CLAUDE_BASH_NO_LOGIN=true.
  • Fixed a security issue where statusLine and fileSuggestion hook commands could execute without workspace trust acceptance in interactive mode.
  • Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity.
  • Fixed a bug where duplicate control_response messages (e.g. from WebSocket reconnects) could cause API 400 errors by pushing duplicate assistant messages into the conversation.
  • Added CLAUDE_CODE_ACCOUNT_UUID, CLAUDE_CODE_USER_EMAIL, and CLAUDE_CODE_ORGANIZATION_UUID environment variables for SDK callers to provide account info synchronously, eliminating a race condition where early telemetry events lacked account metadata.
  • Fixed slash command autocomplete crashing when a plugin’s SKILL.md description is a YAML array or other non-string type

Update Jun 4, 2026 tracked by Updatify

2.1.50

  • Added support for startupTimeout configuration for LSP servers
  • Added WorktreeCreate and WorktreeRemove hook events, enabling custom VCS setup and teardown when agent worktree isolation creates or removes worktrees.
  • Fixed a bug where resumed sessions could be invisible when the working directory involved symlinks, because the session storage path was resolved at different times during startup. Also fixed session data loss on SSH disconnect by flushing session data before hooks and analytics in the graceful shutdown sequence.
  • Linux: Fixed native modules not loading on systems with glibc older than 2.30 (e.g., RHEL 8)
  • Fixed memory leak in agent teams where completed teammate tasks were never garbage collected from session state
  • Fixed CLAUDE_CODE_SIMPLE to fully strip down skills, session memory, custom agents, and CLAUDE.md token counting
  • Fixed /mcp reconnect freezing the CLI when given a server name that doesn’t exist
  • Fixed memory leak where completed task state objects were never removed from AppState
  • Added support for isolation: worktree in agent definitions, allowing agents to declaratively run in isolated git worktrees.
  • CLAUDE_CODE_SIMPLE mode now also disables MCP tools, attachments, hooks, and CLAUDE.md file loading for a fully minimal experience.
  • Fixed bug where MCP tools were not discovered when tool search is enabled and a prompt is passed in as a launch argument

  • Plugins can ship settings.json for default configuration
  • Fixed file-not-found errors to suggest corrected paths when the model drops the repo folder
  • Fixed Ctrl+C and ESC being silently ignored when background agents are running and the main thread is idle. Pressing twice within 3 seconds now kills all background agents.
  • Fixed prompt suggestion cache regression that reduced cache hit rates.
  • Fixed plugin enable and plugin disable to auto-detect the correct scope when --scope is not specified, instead of always defaulting to user scope
  • Simple mode (CLAUDE_CODE_SIMPLE) now includes the file edit tool in addition to the Bash tool, allowing direct file editing in simple mode.
  • Permission suggestions are now populated when safety checks trigger an ask response, enabling SDK consumers to display permission options
  • Sonnet 4.5 with 1M context is being removed from the Max plan in favor of our frontier Sonnet 4.6 model, which now has 1M context. Please switch in /model.

Update Jun 4, 2026 tracked by Updatify

2.1.47

  • Fixed FileWriteTool line counting to preserve intentional trailing blank lines instead of stripping them with trimEnd().
  • Fixed Windows terminal rendering bugs caused by os.EOL (\r\n) in display code — line counts now show correct values instead of always showing 1 on Windows.
  • Improved VS Code plan preview: auto-updates as Claude iterates, enables commenting only when the plan is ready for review, and keeps the preview open when rejecting so Claude can revise.
  • Fixed a bug where bold and colored text in markdown output could shift to the wrong characters on Windows due to \r\n line endings.
  • Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (anthropics/claude-code#26188)
  • Improved memory usage in long-running sessions by releasing API stream buffers, agent context, and skill state after use
  • Improved startup performance by deferring SessionStart hook execution, reducing time-to-interactive by ~500ms.
  • Fixed an issue where bash tool output was silently discarded on Windows when using MSYS2 or Cygwin shells.
  • Improved performance of @ file mentions - file suggestions now appear faster by pre-warming the index on startup and using session-based caching with background refresh.
  • Improved memory usage by trimming agent task message history after tasks complete
