Unclear It is not clear whether this changes the streamed output that people reading Claude Code's own output can see.
What
When Claude's reply arrives as a stream (sent piece by piece instead of all at once), Claude Code now removes a field called input_transformations from two kinds of event before passing them on:
the event that opens a new message
the events that update a message while it is being written
The field name was already known to Claude Code. What is different is that it is now stripped out.
Why
Anything further along that reads these streamed events will no longer see this field.
