RemovedSection of the release
Unclear The sed edit preview may now be shown somewhere else instead of being removed outright.
What
When Claude wanted to run a sed -i style command, which edits a file in place, Claude Code used to show a special permission prompt with a preview of the file edit. That prompt is gone, along with its messages for when a hook rewrote the command. All Bash commands now use the standard Bash permission prompt.
Why
