changeslist_of_most_recent_changesChanges Introduced in V8.0.0

The following describes the most significant changes which have occurred in the AST library between versions V7.3.4 and V8.0.0 (the current version):

  1. The PolyMapPolyMap class now uses files copied from the C/C++ Minpack package (see http://devernay.free.fr/hacks/cminpack/index.html) to perform least squares fitting of N-dimensional polynomials.

  2. Use of the IAU SOFA library has been replaced by ERFA library, which is a re-badged copy of SOFA distributed under a less restrictive license. A copy of ERFA is included within AST.

Programs which are statically linked will need to be re-linked in order to take advantage of these new facilities.
