Apple’s open-source roadmap suggests that lays the groundwork for:

Massive reductions in read-latency, leading to stutter-free transitions on complex, high-speed geometries.

While current versions of the Notre Dame CCTools have surpassed version 7.0, the number often appears in toolchain contexts:

It is important to distinguish the Apple toolchain from other similarly named software:
