Some recent extensions to the GALPROP cosmic-ray propagation package are
described. The enhancements include: an accurate solution option, improved
convection formulation, alternative spatial boundary conditions, polarized
synchrotron emission, new magnetic field models, updated gamma-ray production
cross-sections, free-free radio emission and absorption, primary positrons,
additional injection spectral breaks, deuterium production by pp fusion,
hadronic energy losses, improved HEALPix skymap format, compatibility with
latest HEALPix release, and various bug fixes. The Explanatory Supplement has
been extensively updated, including details of these enhancements. A compatible
plot package GALPLOT for GALPROP output is also provided, as well as other
related software.Comment: Contribution to the 34th International Cosmic Ray Conference, July 30
