## ChangesIntroduced in V5.6-1

The following describes the most significant changes which occurred in the AST library between versions V5.6-0 and V5.6-1:

1. Tables can now have any number of parameters describing the global properties of the TableTable.

2. Frames now interpret the unit string “A” as meaning “Ampere” rather than “Angstrom”, as specified by FITS-WCS paper I.

3. A bug has been fixed in the astFindFrameastFindFrame method that allowed a template FrameFrame of a more specialised class to match a target frame of a less specialised class. For example, this bug would allow a template SkyFrameSkyFrame to match a target Frame. This no longer happens.
