Subsections
all input FITS files can now be compressed (with a
.gz, .Z, .z, or .zip
extension) and/or remotely located (with a ftp:// or http:// prefix).
Version 3.14 (March 2009) or newer of CFITSIO is required for HEALPix 3.0.
introduction of process_mask
facility to compute the angular distance of valid
pixels to the closest invalid pixels for a input binary mask,
sky_ng_sim now allows the computation
of the spatial derivatives of the non Gaussian map being produced, and the
output of the alm coefficients of that map,
anafast now allows the
pro/down-grading of the input mask to match the resolution of the map(s) being
analyzed.

most facilities can handle maps with

In synfast facility, a numerical bug affecting the accuracy of the Stokes parameter derivatives

for X=Q,U has been corrected. See this appendix for details.
The anafast facility can now compute the cross-correlations of two different
maps.
The sky_ng_sim facility (Rocha et al, 2005), to produce non-Gaussian CMB temperature maps,
has been added.
faster implementation of alm related facilities, generalization of
OpenMP parallelization, and availability of MPI parallelized routines (see
mpi_* routines in Fortran90 Subroutines Overview document).
introduction of alteralm facility to modify and/or rotate the spherical
harmonics coefficients alm and greater flexibility for constraining
alm in synfast
