New message tells users their Claude Code version must be updated before continuing, with the exact update command
What
A new message tells the user that their current version of Claude Code is too old, states the minimum version now required, and tells them to run claude update.
Why
This makes clear why Claude Code has stopped working and gives the exact command to fix it, instead of leaving the user to guess what to do.
