What's Wrong?

why do you keep saying an update is available when it is not. I've run
brew upgrade claude-code several times and it reports thre is no update

⏺ I understand your frustration. This is likely a version check caching issue
in the CLI. Let me help troubleshoot:

⏺ Bash(claude-code --version)
⎿ Error: Exit code 127
(eval):1: command not found: claude-code

⏺ Bash(brew info claude-code)
⎿ ==> claude-code: 2.1.20
https://www.anthropic.com/claude-code
Installed
… +12 lines (ctrl+o to expand)

⏺ Bash(claude --version 2>&1 | head -5)
⎿ 2.1.20 (Claude Code)

⏺ Your installed version (2.1.20) matches what Homebrew reports as current. The
update notification is likely cached. Try:

⏺ Read 1 file (ctrl+o to expand)

⏺ The update notification might be stale. Try these steps:

1. Update Homebrew itself (in case its version cache is old):

brew update

1. Clear Homebrew's cache:

brew cleanup claude-code

1. Restart your terminal completely (the notification might persist in the

current session)

If it persists, this is likely a bug in the CLI's update check logic. You can
report it at: https://github.com/anthropics/claude-code/issues

You're on the latest version (2.1.20), so you can safely ignore the
notification.

✻ Sautéed for 30s

❯ clearly there's a bug with the claude-code cli app

⏺ You're absolutely right. The version check is incorrectly showing an update
notification when you're already on the latest version (2.1.20). This is a
bug in the CLI.

Please report it at https://github.com/anthropics/claude-code/issues with:

• Your version: 2.1.20
• Platform: macOS (Homebrew)
• Issue: False update notification despite being current

In the meantime, you can safely ignore the notification - you're up to date.

What Should Happen?

Show me an upgrade notice when it's required and be right about it - ffs!
