+Hi, all,
+
+As you know, Remind has been around for a long time---over 36 years.
+It's written in C, and I think it's high time to rewrite it in a
+memory-safe language.  After all, one CVE in 36 years is simply
+unacceptable.
+
+I was looking at writing it in Rust, but decided that Rust isn't quite
+mature enough yet.  So I decided to do it in FORTAN-77.  I chose
+FORTRAN-77 over the more obvious choice of COBOL because I studied
+engineering and not business.
+
+The rewrite will have the following implications:
+
+o Remind will henceforth be known as REMIND.
+
+o Sadly, I have to drop UTF-8 support.  Your choices are ASCII or
+  EBCDIC.
+
+o All statements must begin in column 7.  That means you might need to
+  edit your existing scripts to add 6 spaces at the beginning of the
+  line.
+
+o Variables whose names begin with "I" through "N" can only hold INTs.
+
+o I will be setting up a store on my web site to sell punched cards.
+  (Yes; those will be needed to run REMIND.)
+
+Now, I confess I haven't programmed in FORTRAN-77 in several decades,
+so I plan on using AI to assist me.  After all, it has been trained on
+the mountains of open-source FORTRAN-77 code on the Internet.
+
+I anticipate the rewrite will take about 9 years.  You can use this
+reminder to alert yourself to when it's ready:
+
+      REM 1 APRIL 2035 MSG REMIND IN FORTRAN-77 READY. STOP.
+
+Regards,
+
+Dianne.

 CHANGES TO REMIND

+* VERSION 06.02.06 - 2026-05-15
+
+- NEW FEATURE: remind: Add $Repeat read-only system variable which is
+  set to N if a command-line repeat of '*N' is supplied.
+
+- NEW FEATURE: remind: You can use a command-line argument of the form
+  '@trigger' to set the current date.  Remind evaluates the trigger
+  and sets today() to the result.  For example, the following command
+  runs Remind in Agenda Mode on the next upcoming Friday the 13th:
+
+      remind filename.rem '@13 SATISFY [$Tw == 5]'
+
+  and the next command runs it on 2026-11-13, the first Friday the 13th
+  on or after 2026-08-01:
+
+      remind filename.rem 2026-08-01 '@13 SATISFY [$Tw == 5]'
+
+- MINOR CHANGE: remind: When you supply the date on the command-line,
+  you can leave out the year, which defaults to the current year in
+  that case.
+
+- MINOR CHANGE: remind: When dumping variables, indicate preserved
+  variables with a <preserved> tag.
+
+- MINOR CHANGE: remind: Issue warnings if we try to FUNSET or
+  PUSH-FUNCS a built-in function.
+
+- BUG FIX: include/holidays/jewish.rem: Rearrange code to improve ICS
+  export.
+
+- BUG FIX: "make install": Remove old holidays files to avoid installation
+  failure because of change in symlink setup.
+
