# Primary Change In order to conform to the cmake overhaul, occurrences of ENABLE_XXX options in the nczarr code have been changed to NETCDF_ENABLE_XXX. # Misc. Other changes * Fix use of rand_s in libdispatch/ncrandom.c * Fix some bugs in the mingw gitub action. * Fix signature bug in libncpoco/cp_win32.c * Make some NCZarr fixes to config.h.cmake.in
