What

Claude Code used to show a Bash command that edited a file with sed, a command-line tool that changes text in files, under a file-edit style label with an edit preview. It no longer does. The label is now:

The simulated edit data that used to travel with such commands is no longer stripped when commands are checked.

Why

The imitation file-edit preview for sed commands is gone, so these commands appear as ordinary Bash commands.
