+
+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.
