What
Two separate additions:
Overload waits: Claude Code's list of named API operations gained one for waiting while the API is overloaded.
Error codes: when a program driving Claude Code through the SDK (the toolkit for controlling Claude Code from code) sends a control request and gets an error back, that reply now includes an error_code field for one particular kind of error.
Why
The overload label points to Claude Code handling overloaded-API waits as their own step. Programs built on the SDK can read error_code to tell that kind of error apart from others.
