Claude Code v2.1.202 Changelog

This update is all about making Claude Code smoother, more reliable, and easier to control. Whether you are managing complex multi-step tasks, using the mobile remote control, or just trying to log in over a remote connection, this release fixes annoying bugs and cleans up the interface so you can code without interruptions.

What's new

• Control your workflow size: A new "Dynamic workflow size" setting in /config lets you suggest how many AI "agents" (sub-tasks or mini-helpers) Claude should use for big tasks (small, medium, or large). It is a helpful guideline for Claude, not a strict limit.
• Better tracking for developers: Added tracking labels (workflow.run_id and workflow.name) to the data Claude sends to monitoring tools (called OpenTelemetry). This helps developers look back and see exactly what their AI agents did during a specific run.

Improvements

• Cleaner workflow screen: The /workflows list layout is now much easier to read. It features wider titles, a dedicated column showing how long tasks took, shorter AI model names, and less clutter.
• Faster code reviews: The /review command is back to being a super-fast, single-pass check. If you want a deep, thorough review using multiple AI agents, you can now use the /code-review command instead.
• Friendlier error messages: If you make a mistake setting up an MCP server (a tool that connects Claude to external data) by forgetting to specify the connection "type," Claude will now politely suggest adding "type": "http" instead of showing a confusing computer-speak error.

Fixes

• No more history search crashes: Fixed a crash that happened if you searched your command history (using Ctrl+R) and tried to accept or cancel the search while it was still loading.
• Sticky session names: Fixed a bug where renaming a background task (using /rename) would accidentally reset back to the old name if the task restarted.
• Smoother security updates: Fixed temporary connection errors (mTLS handshake failures) that happened when security certificates (digital ID cards for servers) were being updated in the background.
• Remote control fixes: Fixed issues where sending commands from the mobile or web Remote Control app would fail with an "Unknown command" error, and fixed a bug where files or images sent without a caption would silently disappear. Also fixed the remote session showing the wrong security permission settings.
• Clickable login links: Fixed login links breaking when using SSH (connecting to another computer remotely). If the link wrapped to a new line, you couldn't click it; now it is formatted as a single, clickable link.
• No more agent crash loops: Fixed a crash loop that happened when trying to open a chat from the claude agents list, which would get stuck thinking the agent was already busy in the background.
• Better script error reporting: Fixed a bug where special characters (like fancy unicode quotes) in workflow scripts would break the code. Also, if there is an error, Claude now points to the exact line that broke instead of giving a generic error.
• Smart microphone pausing: Fixed voice typing getting stuck in an endless loop of trying to record when your microphone isn't working. Now, it will just pause and wait.
• Faster loading in huge projects: Fixed massive slowdowns and high memory usage when opening or resuming saved sessions in very large code projects (specifically those using many Git "worktrees" or project branches).
• Resilient downloads: Fixed the installer giving up immediately if your internet flickered for a second during an update. It will now automatically retry the download.
• Memory saving: Fixed a bug where using a "skill" (a custom tool you taught Claude) multiple times would accidentally paste duplicate instructions into Claude's memory, wasting space.
