A new quick update of the GODUNOV code version 2.3 with just a few fixes:

• make the default host file work with the GNU Fortran compiler,
• add several variable checks in makefile and inform user if the compilation environment is incorrect,
• add parameter files for a few basic test problems,
• remove IDL subroutines for the HDF4 support, since this is not supported anymore.

A new update of the GODUNOV code version 2.2 with a few new features added and several fixes:

• add hyperbolic div(B) source terms to GLM-MHD (option HEGLM),
• store primitive variables in restart files too (this fixes problems in some situations with job restarting),
• improvements to reconstructions LimO3 and MP and rewrite of minmod(), minmod4() and median(),
• implementation of Jenkins & Traub rpoly() and Laguerre’s zroots() root finding subroutines in module ALGEBRA,
• divergence free open boundaries for GLM-MHD.

A small update of the GODUNOV code to version 2.1.

• optimization of the boundaries,
• current density is calculated in sources now.

The next version 2.0 of the GODUNOV code has been released. The changes with respect to the previous version are listed below.

• hyperbolic divergence cleaning using the GLM-MHD equations and EGLM-MHD equations,
• improved the code for shock detection,
• parameter file checker,
• the reduction of memory utilization,
• bug fixes.

Finally, after more that 5 years, I have prepared a version 1.0 of the GODUNOV code, a uniform mesh version of the AMUN code. The list below specifies what the current version of the code supports.

• rectangular (Cartesian) domain in 2D and 3D,
• hydrodynamical (HYDRO) and magnetohydrodynamical (MHD) equations,
• adiabatic (ADI) and isothermal (ISO) equation of state,
• viscosity and resistivity source terms,
• turbulence forcing,
• time integration using Euler and Runge-Kutta methods up to 4th order,
• spatial interpolation using 2nd order TVD methods, 3rd order CENO, WENO3, and LimO3 methods; 5th order WENO and WENO-Z methods, and from 3rd to 9th order monotonicity-preserving (MP) methods,
• the HLL-family of approximate Riemann solvers (HLL, HLLC, and HLLD),
• CD and CT schemes for the induction equation,
• MPI parallelization.
