What

Claude Code can compress the body of a request to the API with gzip (a common compression format). Previously an extra step after the response was attached whenever the request planner asked for it. Now, when a request was sent with a gzip body and comes from one of a particular set of request types, that step is skipped.

Why

This is a small change to how compressed API requests are handled.
