Work on the cosmic-ray propagation/gamma-ray code GALPROP  has been continued with very significant enhancements, including full 3D and time-dependence, and improved cross-sections for CR secondary calculations. Gamma-ray skymaps as a function of energy are produced in FITS format using the computed CR distribution and gas survey data.  GALPROP is implemented in C++.  In addition an effort to provide a visualization tool has been started, using the plotting classes of the CERN "root" package. This allows images, profiles and spectra from the GALPROP models to be compared to data. It shares classes and many routines with GALPROP, to provide an integrated research tool for the study of diffuse gamma-rays.
