## Changes Introduced in V8.0.1

The following describes the most significant changes which occurred in the AST library between versions V8.0.0 and V8.0.1:

1. The BaseBase and CurrentCurrent attributes of a FrameSetFrameSet may now be set using the DomainDomain name or the index of the required FrameFrame.
2. The order of WCS axes within new FITS-WCS headers created by astWriteastWrite can now be controlled using a new attribute called FitsAxisOrderFitsAxisOrder.
3. Supported added for FITS XPH (polar HEALPIX) projection.
4. The macro used to invoke the astAppendStringastAppendString utility function has changed to allow printf-style converstions to be included in the supplied text. Any code that uses this macro must be re-compiled.
5. The astRebin and astRebinSeq family of functions now include support for arrays with char (byte) and unsigned char (unsigned byte) data types.
