Abstract: \({\tt SphericalNR}\) is a new dynamical spacetime and general relativistic MHD evolution framework in spherical coordinates for the \({\tt Einstein Toolkit}\). This talk will present the framework, highlighting algorithmic developments to solve hyperbolic PDEs in spherical coordinates within the Cartesian code base of the \({\tt Einstein Toolkit}\) as well as recent developments, including higher order reconstruction methods and an improved atmosphere treatment.
