The following describes the most significant changes which
occurred in the AST library between versions V9.2.6 and V9.2.7:
- The FitsChanFitsChan class has a new attribute called FitsRoundingFitsRounding, which
controls rounding applied when floating point values are formatted as
FITS keyword values. Note, this changes the default rounding behaviour.
Previously, sequences of four or more 9's or 0's were always rounded.
Now, such sequences are only rounded if they extend beyond the tenth
significant digit (the default value for FitsRounding being 10). To
restore the original behaviour, set FitsRounding to 1.
