Neither "Commons Math" nor "Commons Geometry" are abandoned.

Version 4 aimed at modularization, while several components were spun off (with improved design and for better maintenance): * Commons Geometry * Commons RNG * Commons Numbers * Commons Statistics The overhaul of the remaining "legacy" packages of "Math" is work-in-progress, but has stalled... > - commons-geometry1 is from 2021 It has been stable since then. > > Are those replaced ?
