From: Barbara Beeton
Subject: Details of TeX 2.96-2.98 changes; SYMBOL.MF
Message #13 informed you that TeX bug fixes had brought the version
up to 2.98. The details of these changes are below, in a single
difference list between the WEB files for 2.95 [sic] and 2.98.
The relevant addenda to TeX82.BUG and ERRATA.TeX follow.
The difference list was generated on a VAX under VMS, and the format
of the errata changes is also different from what I usually send.
I have been unable to establish a good enough connection to Score,
where the distribution versions of the files reside, to obtain full
copies of versions after 2.96, and have had to reconstruct the latest
version from partial difference lists. I have done this very carefully,
and believe the lists here to be true and complete, but will verify
that as soon as possible after contact with Score has been
re-established. I realize that some of the lines in the difference
list are longer than 80 characters; the conventions of the VMS file
comparison are different from those under TOPS-20. If any problems
occur in transmission, please let me know, and I will try to generate
a copy in the other format.
I know that it is impossible to validate these changes in your
implementations without a current set of TRIP files. I will try to make
obtaining and sending them my highest priority after meeting a couple
of deadlines that the Math Society finds important. Thank you for
your patience.
A small change has been made to the file SYMBOL.MF. It affects only the
labels on proof output; it should have no effect on .TFM or raster files.
Details are listed below.
