Dear TeXers,

It is sad for me to open yet another letter with the news about the war
in Europe. As I write this, the estimate for the number of Ukrainian
refugees who fled their country is at 5.5 million, with another 7.7
million of internally displaced people. 90% of these 5.5 million are
women and children. Some organizations, like the Canadian parliament,
call the acts of Russia a genocide, and even more organizations
recognize them as war crimes. The danger of the use of weapons of mass
destruction is very high. Many scientific and technology societies do
what they can to help. For example, the American Physical Society held a
plenary session at their Annual Meeting to explore the history and
background of the Russian invasion of Ukraine, and created a support
Our society is much smaller, but we also try to help. Recently the Board
approved free membership for people in war zones and refugees, with full
confidentiality. We are thinking about other ways to help.

In other unhappy news, I am very sad to report the passing of a great
friend and TeX enthusiast, Dave Walden.  Dave was a living history of
computers and computer typesetting, who knew everything and everybody.
He was one of the most generous people I ever knew, always here to
help and support.  He was a TUG director and treasurer for many years.
I learned a lot from Dave and his advice.  He will be missed.  (A longer
memoriam will appear in the next TUGboat.)
