The book Quantum Computing and Quantum Information by Nielsen and Chuang is a well-known and celebrated text book that can act as a resource in a wide variety of topics. Of course, in such a vast textbook there might arise small errors.
Its own preface (at least in the $10$th anniversary edition) addresses this as well, and links to the website
http://www.squint.org/qci/ for a list of errata and requests any newly found errors to be send to
firstname.lastname@example.org. Neither links are still functional, let alone maintained.
There is also the list of errata to be found on the website of Dr. Nielsen, although this doesn't seem to be maintained anymore either: there is a time-stamp from back in $2014$ and the list refers to the first until the fifth print of the book, which is not the last print of the book.
A google search provides some other resources, sometimes PDF documents, which all seem to be one version or another of the list of errata linked above.
My question is: Is there (still) an 'official' or 'semi-official' list of errata, preferably for the $10$th anniversary edition, and also preferably still being maintained?
As a follow up question, is there also a way to notify the maintainers about any as of yet unnoticed errors?
