Features refer to the observed 0.7.0 (8) beta source and testing reports, not an unrestricted MATLAB or Mathematica replacement.
Build 8 is a beta with important limits: it is not an arbitrary-precision engine, a general Python runtime, an unrestricted computer algebra system, or a full symbolic MathTensor replacement. Covariant differentiation, multi-term curvature identities, and complete metric variations remain future work.
Some macOS 0.7.0 (8) resizing and Settings interactions were awaiting fresh distributed-build acceptance at documentation time. The website deliberately does not present earlier concept artwork as genuine captured screenshots.
