Pharo 6 was shipped with Renraku — the single quality model to rule them all. While being an advanced piece of software, Renraku alone provided no immediate benefits to end users. In this talk, we are going to present the upcoming development changes that utilize Renraku and range from advanced bug fixing guidance to the five times speed up in quality rules; as well as a few more usability features.
