Despite some initial fears, this transfer of ownership hasn’t negatively impacted users, and SuperSU is yet chugging together. On the other hand, Chainfire’s two-year contract with CCMT is operating out, Therefore it’s period for him to move on. To which? A lot of stuff, probably.
According to Chainfire, part of the deal was that he’d remain involved with SuperSU for two years as CCMT took over development. During that time, typical updates have continued, and Chainfire has completed a full code review.

Chainfire intends to shift his focus a bit, but that doesn’t mean it’s likely to leave mobile development behind. He did just release firmware.mobi announced this month as an excuse to mess about with Python. He’d apparently such as to use some of his newfound freedom to experiment with Swift and Kotlin as effectively. Whatever Chainfire does, I’m sure the Android community wishes him effectively.
