Improving opening theory (update of my chess book)

 A few years ago i wrote a book about opening theory specifically aimed

at beginner and intermediate levels; this is/was the paper version of the book:

Better-Chess-Openings (Amazon)

There also is an E-book version (and some other review) with various outlets (eg lulu.com/kobo), but the above  is key. The book was based on chess programs (engines) at that time, which already analyzed positions better  than  human chess grandmasters. However in recent years the chess engines were again considerably improved  due to the use of neural networks (the NNUE approach). As a result I had to check the content  of the book, and the recommended 'repertoire' (main  variations for Black and White). For this purpose in  last two  months I have analyzed two million of the most important opening positions added  the improved results to my computer chess 'opening book' did 'backsolving' some checks and finetuning on the final results. 

Luckily I found that  the  older 'main' opening choices ('repertoire')  still basically are correct (as result  of earlier deep/thorough analysis it appears I  was  ahead of my time) but many variations now do need an update in specific  moves,  and  sometimes  the order  of importance  for specific variations (recommended top choices) will be  changed.  This means it now is time for a  second, completely NEW, improved Edition, based on the latest  ('NNUE')  engines and a systematic analysis of  ALL relevant opening positions starting from scratch. 

Thereby many variations will get an update wrt the specific moves usually from move 3 or 4 onwards, and sometimes  the order of importance for specific variations (recommended top choices) will be changed. An example of a variation  which  has become almost obsolete as result of the engine analysis , is the French Winawer for Black. While I already  not recommended it for Black, I know can list the best moves for White to refute the variation,  in case  Black would play such the -erroneous/outdated- ...Bb4?!.  Also in the chapter with gambits,  and the more advanced 'positional' chapter (with 1.d4) there will be changes in the recommended moves, usually after move 3 or 4 or so, while maintaining the main structure  of the (sub)chapters.
