+Date: 14 Aug 88 Message No: 008
+
+To: TeX implementors and distributors
+
+From: Barbara Beeton
+
+Subject: TeX 2.93, again; LaTeX and AMS-TeX
+
+
+I received the following message from Don Knuth on July 13, as I was
+preparing to go to TeX88 in Exeter:
+
+ Subject: minor problem with TeX version 2.5
+
+ The variable cur_order should be initialized to something, because
+ there are Pascal compilers that don't allow you to say "a:=b" when
+ b hasn't been given a value (even if that value is never used).
+
+ I'll put that fix into version 2.93 so that the changes are confined
+ to TEX.WEB alone. The bug really won't hurt anybody except a brand
+ new implementor.
+
+So this change should be incorporated into TeX 2.93; there will be no
+change in the version number.
+
+Below you will find the new additions to TeX82.BUG, a comparison between
+the TeX.WEB files for versions "2.93a" and "2.93b", and additions to
+ERRATA.TeX. There were no changes to TRIP.*.
+
+All relevant files are now up to date at SCORE.
+
+TRIP.TeX and TRAP.MF were sent several weeks ago. I will be breaking
+the .LOG files into pieces and sending them soon, also the "auxiliary"
+files -- .TYP, .PL, etc.
+
+There have been some recent changes to LaTeX. The following items are
+included below: differences between the addenda file from 12 May 88
+through the latest, and differences in SliTeX.TeX from 10 November 86
+through 8 June 88. I have no earlier version of the addenda file to
+compare; if you would like the complete file sent, please let me know,
+and I will be happy to mail it. A file of differences between LaTeX.TeX
+of December 85 through the latest is being mailed separately; it is very
+large ( >52K bytes), and may have to be mailed in more than one section.
+I am sorry that I could not use a more convenient version of LaTeX, but
+the only ones I have available are from December 85 and April 88, and
+it seemed that using the older one would be helpful to more of you,
+since I have not previously distributed any LaTeX updates. There are
+some notes at the beginning of the LaTeX differences file that you
+should read before doing anything with the file.
+
+A small change has been made to the distribution version of AMSTeX.TeX,
+to fix a bug in \dots that shows up in some rather obscure circumstances.
+The details are described in the file AMSTeX.CHG. Both files are at
+Score in <TEX.AMSTEX> . AMSTeX is now at version 1.1d. If you are
+distributing AMSTeX and cannot retrieve the files from Score, please
+let me know, and I will mail you the up-to-date files; please include
+a list of all the AMSTeX-related files you now have, and their dates.
+Other files in the group have been changed within the past year, but
+the changes were not too well advertised.
+
+Finally, please acknowledge your receipt of this message. Several new
+names have been added to the list, and some addresses have changed. I'd
+like to make sure that they're all working.
