The following describes the most significant changes which
occurred in the AST library between versions V9.0.0 and V9.0.2:
- The AST sharable libraries now use a non-zero version number.
- The FitsChanFitsChan class has a new attribute called ForceTabForceTab, which is used
in conjunction with the TabOKTabOK attribute to force the use of the
“-TAB” algorithm when writing a FrameSetFrameSet out using the FITS-WCS encoding.
