Unclear It is not stated which file names or prefixes the extra list contains.
What
Claude Code periodically deletes old files it no longer needs. Before, this cleanup removed history.jsonl and one other kind of file. It now also removes a list of other file names, and files whose names start with certain prefixes. Those extra files are deleted through a separate step instead of being removed directly.
Why
More stale files are cleared away. If you keep files of your own next to Claude Code's history, note that the set of files removed is larger than before.
