v2.0.0

Command output now uses a StreamName enum, making the choice of input, output or error stream explicit. Repeated-line output also behaves more consistently when you write a line in several parts. When upgrading, replace Stream::IN, Stream::OUT and Stream::ERROR with the corresponding StreamName cases, pass enum values instead of strings, and update your imports to GT\Cli; this major release no longer registers the Gt\Cli autoload prefix.
