This new version contains a number of minor improvements and a few bug fixes.

The changes in detail are (see also the CHANGES file in the distribution):

• 1-D AMR extended to cylindrical and spherical coordinates.
• Entropy switch is available again for the MHD module.
• improved efficiency and accuracy of the GLM-MHD module.
• improved characteristic interpolation.
• CTU integrator is less memory consuming.
• Improved pload function (for IDL users) for large data sets.
• Bug fix in 3-D polar coordinates: the centrifugal term is now correctly included.
• Bug fix in 3-D Cartesian/MHD/FLUX_CT + UCT_CONTACT: the dEy_dxm derivative was added to Ez instead of Ey.
• Bug fix in time step computation for viscous term: a division by density was missing.
• Bug fix in the vector potential in 2D Cylindrical coordinates: the \phi component of the EMF must flip sign before updating A_\phi.
