## Changes Introduced in V7.0.6

The following describes the most significant changes which occurred in the AST library between versions V7.0.5 and V7.0.6:

1. A bug has been fixed in astRebinSeq<X> which could result in incorrect normalisation of the final binned data and variance values.

2. When reading a FrameSetFrameSet from a FITS-DSS header, the keywords CNPIX1 and CNPIX2 now default to zero if absent. Previously an error was reported.
