I've released version 1.37 of GeographicLib. See
http://geographiclib.sf.net/html/changes.html
A couple of items might be of interest to the readers of this list.
(1) Classes and a utility for computing rhumb lines. For details, see
http://geographiclib.sf.net/html/rhumb.html
(2) Support for high precision arithmetic. A compilation option is
provided to allow linking against Boost (for quad precision) or MPFR
(for arbitrary precision). Thanks to C++'s operator overloading this
entailed minimal changes to the code itself. For details, see
http://geographiclib.sf.net/html/highprec.html
