1) After about three years, I finally added copy constructors:

Of course, now I stress that postblit is discouraged.
2) The other noteworthy change in the book is my now-different stance on
variables: Now I recommend 'const' over 'immutable' for variables. And I
favor 'in' for parameters over 'const'. (Unfortunately, not all code in
the book follow those guidelines.)
And I recommend the -preview=in command line switch:

3) I've updated all electronic formats: PDF, EPUB, AZW3, and MOBI:

I had some trouble with ebooks in the past: The fonts would not work and
table of contents would not be generated. Please let me know if you see
something wrong.
WARNING: The paper book publishers are not updated yet. If you order a
paper book now, you will get the old book. (I think from December 2020.)
