The following describes the most significant changes which
occurred in the AST library between versions V1.8-2 and V1.8-3:
- A new method called astDecomposeastDecompose has been added to the MappingMapping class
which enables pointers to be obtained to the component parts of CmpMapCmpMap and
CmpFrameCmpFrame objects.
- Functions within proj.c and wcstrig.c have been renamed to avoid name
clashes with functions in more recent versions of Mark Calabretta's wcslib
library.
