We have recently added several new microphysics tools and routines. The first is EOSmaker, this set of routines is what we use to construct our .h5 tables from the data tables provided from nuclear theorists. Along with this we have updated the H. Shen et al. table, which now uses the updated table from Shen, H. et al. (2011). The second tool is NuLib, a preliminary set of open-source neutrino interaction routines.
