Claude Code Latest Version and Changelog

How to check the latest Claude Code version, update the CLI, read changelog notes, and troubleshoot version mismatches.

Use this page to check the current Claude Code version safely. Claude Code changes quickly, so this page focuses on reliable verification steps instead of copying a long static changelog that can become stale.

Check Your Installed Version

claude --version

If the command is not found, return to the installation guide and confirm the CLI is installed in the same terminal environment where you work.

Check the Latest Published Version

npm view @anthropic-ai/claude-code version

You can also open the Claude Code npm package and compare the published version with your local claude --version output.

Update Claude Code

npm install -g @anthropic-ai/claude-code@latest
claude --version

If your installation method is different, follow the official setup instructions for that method rather than mixing installers.

When to Update

Update when you need a recently documented feature.
Update when troubleshooting suggests a bug was fixed in a newer version.
Update a team gradually if Claude Code is part of a shared workflow.
Avoid updating in the middle of a release unless the current version is blocking you.

Version Troubleshooting

`claude --version` still shows the old version

Your shell may be resolving a different binary. Check which executable is being used:

which claude
npm list -g @anthropic-ai/claude-code --depth=0

Windows or WSL shows different versions

PowerShell, WSL, and IDE terminals can each use a different Node/npm environment. Install and update Claude Code inside the terminal environment where the project actually runs.

Update succeeds but behavior looks different

Read the official documentation and test on a small repository first. For risky project changes, use Plan Mode before editing files.
