Date: 22 October 90 Message No: 027
To: TeX implementors and distributors
From: Barbara Beeton
Subject: AMSFonts bug; TeX 3.1; MF 2.7
This will be a short message. I am constrained by a TUGboat printer
deadlne, but it's been so long since anything has been reported, I
wanted to let you know I'm still alive.
A bug was reported in the AMSSYM.DEF file in the AMSFonts package. The
fix has not yet been posted to the file on e-Math, but is listed below.
The symptom is "unidentified control sequence" for \setboxz@h when
trying to use \widetilde or \widehat. If you have not yet heard about
e-Math (most of you should have received a message from Regina Girouard
describing what is available there and how to retrieve it), please let
me know, and I will send information.
Chris Thompson has suggested that, similar to the occasional reports
of files changed at labrea, I include in these messages a report of
files changed at e-Math. I will try to get a baseline listing of the
e-Math holdings for later comparison, and make reports as suggested.
As of August 15, I had completed my scan of old mail files and double
checked that all bug reports and questions forwarded to me had been
delivered to Don Knuth. (Actually, the last of the pending reports had
been delivered earlier, but I can say with a clear conscience that I
think i found all messages that had arrived electronically and passed
them on. A few have arrived since then, and I will forward them as
soon as TUGboat has been delivered.) I have received from Don (on paper)
a pile of annotated reports and several checks; I will forward those to
the proper people as soon as TUGboat, ...
In the meantime, TeX is now at version 3.1, MF is at version 2.7, and
at least some of you may have seen Don's announcement that the numbers
will converge to $\pi$ for TeX and $e$ for MF. (It will be published
in TUGboat 11#4, but I will forward it to this list if I have time
before that appears.) There was a massive update of files at labrea
on September 21. On some (e.g. cm85.bug) only the dates have changed;
too bad the Unix file system isn't better about keeping meaningful
dates. In any case, the new errata and bug additions for TeX and MF
are attached below.

New errata in ERRATA.TEX as of 21 September 90
\bugonpage A124, lines 18--21 (9/5/90)
\ninepoint\noindent
Floating insertions can be accommodated
as a special case of split insertions, by making each floating topinsert
start with a small penalty, and by having
zero as the associated |\floatingpenalty|; non-floating insertions
like footnotes are accommodated by associating larger penalties with
split insertions (see Appendix~B).
\bugonpage A165, lines 2--3 (8/13/90)
\ninepoint
Type the formula $\bf\bar x^{\rm T}Mx={\rm0}\iff x=0$,
using as few keystrokes as possible.
\ (The first `0' is roman, the second is bold. The superscript `T' is roman.)
