 CHANGES TO REMIND
 
+* VERSION 06.02.04 - 2026-02-15
+
+- IMPROVEMENT: remind: Add the mblower and mbupper functions, which are
+  multibyte counterparts to lower and upper.
+
+- MINOR NEW FEATURE: remind: Add the $Shaded system variable that counts
+  how many times a "SPECIAL SHADE" reminder has triggered.  See the
+  man page for an example of how this can be useful.
+
+- MINOR IMPROVEMENT: Make all programs that ship with Remind (remind,
+  rem2ps, rem2pdf, rem2html and tkremind) accept a --version long option.
+
+- CHANGE: remind: Remind used to warn if the POP-OMIT-CONTEXT, POP-VARS
+  or POP-FUNCS command corresponding to the relevant PUSH command was
+  in a different file than the PUSH command.  But there are valid use
+  cases for this, so Remind no longer emits the warning unless you use
+  the "-dp" debugging flag.
+
+* VERSION 06.02.03 - 2026-02-05
+
+- NEW FEATURE: rem2html: Add a new --yaag option to produce a calendar
+  in the "year-at-a-glance" format.  This format features a table with
+  an entire month in each row.  Thanks to Robert Black for suggesting
+  this and for helping out with the CSS.
+
+- CHANGE: remind: If standard output is a TTY, then default
+  $TerminalHyperlinks to 1
+
+- CHANGE: remind: Increase the default value of $MaxSatIter from 1000
+  to 10000, reflecting the higher speed of the new expression
+  evaluation engine as well as the speed of modern CPUs.
+
+- UPDATE: examples/remind.vim: Update the URL to point to maintained
+  version.
+
+- IMPROVEMENT: include/sun.rem: Add Wikipedia links for sunrise/sunset
+
+- IMPROVEMENT: Add MOON, SHADE, WEEK, COLOR and COLOUR to the Emacs
+  syntax highlighting keyword list.
+
+- IMPROVEMENT: If an invalid value is assigned to a system variable,
+  issue the error "Invalid value for system variable" rather than
+  "Type mismatch"
+
+- DOC FIX: Fix typo in man page
+
+- BUG FIX: rem2html: Eliminate "use of uninitialized variable"
+  warning.
+
+- BUG FIX: remind: The "trigbase" JSON key in "remind -pp" output had
+  an incorrectly-formatted value.  This has been fixed; thanks to
+  Georg Simon for reporting this bug.
