a note on some improvements

[dr.mt...@gmail.com]

The recent interest in Shen (thousands of views in a day) has prompted mt to look at the first chapter and make some changes.  I've tightened up the narrative of the history of Shen.  

In regards to the complaints about reading the 4th edition online; I've dealt with that.  But its worth noting that the technology in that site is roughty 2020.  There has been some improvement and a raising of expectation wrt resolution since the site was built.  It's OK for a fast reference and for a feel of the book ('Is this worth buying, I'll look') and I've read large chunks wo effort - and I have poor vision.    It can be redone to a higher resolution but it is not a priority for me being a lot of work if the new edition is used.   epub however is not a lot of work, and the new hardcopy is £30.  ChatGPT suggests £18 for epub which I think is about right.  

However wrt tigtening the history of Shen, I've done that and I'l post it on this site for anybody who is interested in a story spanning 30+ years of development.
