What
Three small changes:
Scheduled times: a time is now rounded up to the next whole minute.
Settings copies: when copying settings, Claude Code skips a key named __proto__, a special name in JavaScript that can cause unexpected behaviour if copied.
Error output: an error on the error output stream (stderr, where programs print problems) now makes Claude Code give up on output that has not been written out yet, instead of waiting for it.
Why
These are small hardening fixes that make Claude Code behave more predictably in edge cases.
