Changes in Version 41

Although the main work has been on consolidation some new patterns have been added, see below.

A significant problem has always been to name places and buildings in a consistent manner (arising from the different sources used). For those in Iran, Saied Khaghani has checked a large list of places for consistency with corrections made in many cases. Only one of the various spellings is now used for Madrasah.

Internal documentation is available on the system design. Please contact Brian Wichmann if you are interested.
