hi inhom group,


       * SageMath 9.2 is released: https://sagemanifolds.obspm.fr/
         updates include:
          * orientation of manifolds and vector bundles
          * dot_product(), cross_product() and norm() can be now be
            used for vector fields defined along a curve in a
            pseudo-Riemannian manifold
          * action of a bundle connection on sections

       * ET new release: http://einsteintoolkit.org/about/releases/ET_2020_11_announcement.html
