Claude Code Changelog

Fixed local slash command output like /cost appearing as user-sent messages instead of system messages in the UI

Project configs & auto memory now shared across git worktrees of the same repository

Added `ENABLE_CLAUDEAI_MCP_SERVERS=false` env var to opt out from making claude.ai MCP servers available

Improved `/model` command to show the currently active model in the slash command menu

Added HTTP hooks, which can POST JSON to a URL and receive JSON instead of running a shell command

Fixed listener leak in bridge polling loop

Fixed listener leak in MCP OAuth flow cleanup

Added manual URL paste fallback during MCP OAuth authentication. If the automatic localhost redirect doesn't work, you can paste the callback URL to complete authentication.

Fixed memory leak when navigating hooks configuration menu

Fixed listener leak in interactive permission handler during auto-approvals

Fixed file count cache ignoring glob ignore patterns

Fixed memory leak in bash command prefix cache

Fixed MCP tool/resource cache leak on server reconnect

Fixed IDE host IP detection cache incorrectly sharing results across ports

Fixed WebSocket listener leak on transport reconnect

Fixed memory leak in git root detection cache that could cause unbounded growth in long-running sessions

Fixed memory leak in JSON parsing cache that grew unbounded over long sessions

VSCode: Fixed remote sessions not appearing in conversation history

Fixed a race condition in the REPL bridge where new messages could arrive at the server interleaved with historical messages during the initial connection flush, causing message ordering issues.

Fixed memory leak where long-running teammates retained all messages in AppState even after conversation compaction

Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently

Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction

Added "Always copy full response" option to the `/copy` picker. When selected, future `/copy` commands will skip the code block picker and copy the full response directly.

VSCode: Added session rename and remove actions to the sessions list

Fixed `/clear` not resetting cached skills, which could cause stale skill content to persist in the new conversation

Added `/copy` command to show an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response.

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

Improved ordering of short task lists

Improved memory usage in multi-agent sessions by releasing completed subagent task state

Fixed MCP OAuth token refresh race condition when running multiple Claude Code instances simultaneously

Fixed shell commands not showing a clear error message when the working directory has been deleted

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

The `/model` picker now shows human-readable labels (e.g., "Sonnet 4.5") instead of raw model IDs for pinned model versions, with an upgrade hint when a newer version is available.

Managed settings can now be set via macOS plist or Windows Registry. Learn more at https://code.claude.com/docs/en/settings#settings-files

Added `WorktreeCreate` and `WorktreeRemove` hook events, enabling custom VCS setup and teardown when agent worktree isolation creates or removes worktrees.

Subagents support `isolation: "worktree"` for working in a temporary git worktree

Added Ctrl+F keybinding to kill background agents (two-press confirmation)

Agent definitions support `background: true` to always run as a background task

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.

Improved startup performance by caching MCP auth failures to avoid redundant connection attempts

Improved startup performance by reducing HTTP calls for analytics token counting

Improved startup performance by batching MCP tool token counting into a single API call

Fixed `disableAllHooks` setting to respect managed settings hierarchy — non-managed settings can no longer disable managed hooks set by policy (#26637)

Improved permission prompts for path safety and working directory blocks to show the reason for the restriction instead of a bare prompt with no context

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

Improved memory usage during long agent sessions by eliminating O(n²) message accumulation in progress updates

Fixed the bash permission classifier to validate that returned match descriptions correspond to actual input rules, preventing hallucinated descriptions from incorrectly granting permissions

Fixed API 400 errors ("thinking blocks cannot be modified") that occurred in sessions with concurrent agents, caused by interleaved streaming content blocks preventing proper message merging.

Simplified teammate navigation to use only Shift+Down (with wrapping) instead of both Shift+Up and Shift+Down.

Fixed an issue where a single file write/edit error would abort all other parallel file write/edit operations. Independent file mutations now complete even when a sibling fails.

Added `last_assistant_message` field to Stop and SubagentStop hook inputs, providing the final assistant response text so hooks can access it without parsing transcript files.
