Well, many descriptions in the TeXbook are outdated, for example
the name confusion with the Text EXecutive processor in Chapter 1,
and the statement that "videotapes of these courses are available
for rental" from TUG in Appendix J :)

If this counts as a bug, the name "letterformat.tex" in Appendix E
will also count, since the file is distributed as "letter.tex" in
Knuth's local distribution.

If this doesn't count as a bug, it may be better to drop my earlier
report on A299 and C226 at
because it was possible that back in the 80s version differences were
the major cause of "fatal format file errors" and file corruptions
were so rare/trivial as to be not worth mentioning.
