## Changes Introduced in V7.0.3

The following describes the most significant changes which occurred in the AST library between versions V7.0.2 and V7.0.3:

1. A bug has been fixed which could cause an incorrect axis to be used when accessing axis attributes within CmpFrames. This could happen if axes within the CmpFrameCmpFrame have been permuted.

2. A bug has been fixed in the SkyFrameSkyFrame class that could cause the two values of the SkyRef and/or SkyRefP attributes to be reversed.

3. Bugs have been fixed in the CmpRegionCmpRegion class that should allow the border around a compound RegionRegion to be plotted more quickly, and more accurately. Previously, component Regions nested deeply inside a CmpRegion may have been completely or partially ignored.

4. A bug has been fixed in the Plot3DPlot3D class that caused a segmentation violation if the MinTick attribute was set to zero.

5. The astResampleX set of methods now includes astResampleK and astResampleUK that handles 64 bit integer data.
