Most members concern the TUI raising UnicodeEncodeError when surrogate characters are written to the transport stream, with a bug report and fixes that sanitize or escape them. One member adds errno.EINVAL to PEER_GONE_ERRNOS for Windows detached stdout, which is a related but distinct transport error-handling change.
