\noindent This is a list of all substantial corrections made to {\sl Computers
\& Typesetting\/} from the mid-1990s until the first ``Millennium edition'' was
published at the end of the year 2000.
Corrections made to the softcover version of {\sl The \TeX book\/} are
the same as corrections to Volume~A\null. Corrections to the softcover
version of {\sl The \slMF\kern1ptbook\/} are the same as corrections
to Volume~C\null. Changes to the mini-indexes
and master indexes of Volumes B, D, and~E are not shown here unless they are
not obviously derivable from what has been shown.

Point $(1.53745,9.05345)$, where there was a vertical tangent, has been
rounded to $(2,9.05348)$; point $(10.85147,-.00049)$, where there was
\vadjust{\goodbreak}%
a horizontal tangent, has been rounded to $(10.85873,0)$; the intermediate
control points have been adjusted accordingly. \ (Rounding of $x$~coordinates
has been done separately from $y$~coordinates.) \ Finally, with
$\\{autorounding}=2$, additional adjustments are made so that the
$45^\circ$ transition point will occur at what \MF\ thinks is a good spot:
