DiffPDF 2.1.3 finds only two tiny (if weird) differences in the appearance of the two versions of the books (https://yurichev.com/writings/AL4B-EN.pdf https://yurichev.com/writings/AL4B-EN.pdf and https://beginners.re/RE4B-EN.pdf https://beginners.re/RE4B-EN.pdf) besides the title, author and build date: two page references at pages 1075 and 1078. Since both sites appear to be owned by the book's author this is most likely just a change that has not yet been pushed to github (or mentioned in the author's sites), but it would be better if the author clarified it (would that be you, dennis714?)
