I think it involved a planet called …

… Sky’s Edge, if I recall correctly. Except the “new tech” was not FTL (not a thing in Revelation Space canon) but the practice of ejecting a significant fraction of hibernating colonists and their supplies to buff their deceleration ability in order to hold higher interstellar velocity for longer so as to get a few years “edge” in lead time over other generation ships. All to enable the traitorous ship of the generation ship fleet to raid planetary resources sooner to build up military forces to raid the slower latecomers.
