Changes Introduced in V8.3

The following describes the most significant changes which occurred in the AST library between versions V8.2.0 and V8.3.0:

  1. A new method called astAxNormastAxNorm has been added to the FrameFrame class that normalises an array of axis values. When used with SkyFrames, it allows longitude values to be normalised into the shortest range.

  2. A bug has been fixed in the astGetRegionBoundsastGetRegionBounds method that could cause the wrong bounds to be returned for regions spanning a longitude = zero singularity.
