A large update to my history of Pascal and its standards, where it comes from, the early compilers, sources of first compilers, unique articles and rare books, originally scanned, written by Niklaus Wirth, Per Brinch Hansen, Tony Hoare, Dijkstra, Jim Welsh and many more. Come and see it at http://pascal.hansotten.com
Is there a summary of the changes somewhere?
This is a great collection! Thank you very much for the effort!
A summary would be as large as the site listing itself 
I rewrote and enhanced nearly all pages about ‘historical’ Pascal and added many.
