 CHANGES TO REMIND
 
+* VERSION 4.2 Patch 1 - 2022-12-15
+
+- MINOR IMPROVEMENT: TkRemind: If "Extra Remind Options" contains -m, make
+  TkRemind start the calendar with Monday instead of Sunday.
+
+- MINOR IMPROVEMENT: Sample files: Add French holidays courtesy of
+  Clément Bœsch.
+
+- MINOR IMPROVEMENT: A few performance fixes, likely not even noticeable in
+  most cases.
+
+- MINOR FIXES: Fix misleading comments in the source code.
+
+- MINOR FIX: Remove a bunch of dead code in the moon-phase routines.
+
+- MINOR FIX: Remove unnecessary %"...%" markers in holidays/us.rem
+
+- MINOR FIX: Don't use the -ffat-lto-objects if we're compiling with Clang.
+
+- MINOR FIX: Remind: Fix a broken printf-format string (need to double up on %
+  to get a literal % in the output.)
+
+- BUG FIX: Make test suite pass regardless of the date on which it is run.
+  D'oh!!!
+
+- BUG FIX: Make sure the banner gets printed each time through a "*N"
+  command-line option loop.
+
+* VERSION 4.2 Patch 0 - 2022-10-14
+
+- NEW FEATURE: remind: Allow weekdays to be globally-omitted.  For example:
+
+       OMIT Saturday Sunday
+
+  globally-omits all Saturdays and Sundays.
+
+- NEW FEATURE: remind: Add ansicolor() built-in function to make it easier
+  to colorize reminders on the terminal.  Suggested by Tim Chase.
+
+- NEW FEATURE: remind: Add several special variables related to the color
+  mode: $UseVTColors, $UseBGVTColors, $Use256Colors, $UseTrueColors and
+  $TerminalBackground.  Based on a suggestion by Tim Chase.
+
+- NEW FEATURE: remind: Add utctolocal() and localtoutc() built-in functions.
+
+- NEW FEATURE: remind: Add timezone() built-in function.
+
+- NEW FEATURE: remind: Add trigtags() function per suggestion from Tim Chase.
+
+- NEW FEATURE: remind: The $AddBlankLines system variable controls whether or
+  not a blank line is added after each reminder.
+
+- NEW FEATURE: remind: The built-in functions columns() and rows() return the
+  width and height of the terminal (in character positions) respectively.
+
+- NEW FEATURE: remind: The built-in function columns("string") returns the
+  number of columns occupied by "string" on the terminal, taking into account
+  double-width Unicode characters and zero-width ANSI escape sequences.
+
+- NEW FEATURE: remind: You can add custom substitution sequences of the form
+  %{name} or %*{name} that end up calling the function subst_name and using
+  its return value as the replacement for the substitution sequence.
+
+- NEW FEATURE: remind: Add the FUNSET command to undefine a user-defined
+  function.
+
+- NEW FILES: Add standard include files holidays/jewish.rem and
+  ansitext.rem (the latter defines standard ANSI escape codes for
+  changing text attributes such as bold, underline, etc.)
+
+- NEW EXAMPLES: add examples/alignmemt.rem, examples/ansitext and
+  examples/astro
+
+- BUG FIX: remind: Make MSF correctly format UTF-8 text and text with
+  embedded ANSI color-changing codes.
+
+- BUG FIX: remind: Make ADDOMIT actually work correctly in a SATISFY-type
+  REM command.  Bug found by Gunther Reißig
+
+- BUG FIX: Convert documentation files and src/lang.h to UTF-8.  Patch
+  from Jochen Sprickerhof.
+
+- BUG FIX: Fix tests in non-UTF-8 locales.
+
+- BUG FIX: Fix a few problems with the include/holidays/us.rem file.
+
+- BUG FIX: remind: Fix an ancient logic error in DBufPutc that hurt
+  performance.
+
+- MINOR IMPROVEMENT: Clean up code and remove some dead code.
