misc: * maintainers please look at (large number) of tickets up for review * Kristen Boydstun at Caltech has written a Con2Prim routine using OpenCL which runs on a GPU and finds a 2x speedup (incl. data transfer) for about 10,000 zones and more for larger grids * will include Christian Reisswig's SphericalSlice in ET * propose to include GT's Outflow thorn in ET
MHD: * Roland implemented unigrid, cell-centered constraint transport in GRHydro (which is what WhiskyMHD uses, with help from Bruno Giacomazzo) * Tanja mostly implemented the algebraic gauge vector potential method with vector potential at the centre (also what WhiskyMHD uses), held up by EOS_Omni fixes
Yours, Roland
