You'll notice
Duplicating a config/session directory now also copies .config.json and additional .claude*.json profile files
What
When Claude Code duplicates a config or session directory, it now also copies .config.json and, for each suffix in a new list, a .claude${suffix}.json file, in addition to the existing .claude.json, settings.json, and cowork_settings.json files it already copied.
Why
This brings more of a user's profile-related settings files along when a config directory is duplicated, so a copied session or config more fully reflects the original setup.
