## Changes Introduced in V1.8-3

The following describes the most significant changes which occurred in the AST library between versions V1.8-2 and V1.8-3:

1. 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.

2. 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.
