Changes Introduced in V3.1

The following describes the most significant changes which have occurred in the AST library between versions V3.0 and V3.1 (the current version):

  1. Addition of a new class called XmlChanXmlChan - a ChannelChannel which reads and writes AST objects in the form of XML.
  2. A bug has been fixed in the PlotPlot class which could cause incorrect graphical attributes to be used for various parts of the plot if either axis has no tick marks (i.e. if both major and minor tick marks have zero length).

Programs which are statically linked will need to be re-linked in order to take advantage of these new facilities.
