 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.
+
+* VERSION 4.1 Patch 0 - 2022-09-25
+
+- NEW FEATURE: remind: "remind -c" now supports the MOON special, printing
+  the moon phases in the calendar if the locale supports UTF-8 encoding.
+
+- NEW FEATURE: remind: "remind -c" now supports the SHADE special.  Works
+  best with the 256-color extended XTerm palette or 24-bit true-color
+  terminal escape sequences.
+
+- NEW FEATURE: remind: "remind -c" now supports the WEEK special.
+
+- NEW FEATURE: remind: The new "stdout()" function returns a string describing
+  where stdout is going.  Examples of return values are "TTY" if remind's
+  output is going to terminal, "FILE" if it's redirected to a plain file,
+  or "PIPE" if it's going to a pipe.  See the man page for all the details.
+
+- NEW FEATURE: Add the "-wt" option to set the calendar width to the terminal
+  width even if standard output is a pipe.  Useful for situations like this:
+
+      remind -wt -c .reminders | less -R
+
+- CHANGE: "make install" now no longer strips debugging symbols from the
+  remind and rem2ps executables.  Use "make install-stripped" if you want
+  them stripped.
+
+- CHANGE: remind: "remind -c" highlights today's date in bold, if
+  colors are enabled.
+
+- CHANGE: Dump string values with control characters escaped.
+
+- DOCUMENTATION FIX: Document behavior of DO and filedir() with respect
+  to symbolic links.
+
+- DOCUMENTATION FIX: Add home page link to man pages.  Suggested by Ian! D.
+  Allen.
+
+- DOCUMENTATION FIX: Make date in man pages actually be the release date.
+  Include Remind version in man pages.  Also suggested by Ian! D. Allen.
+
+- DOCUMENTATION FIX: Fix inaccuracy in how string constants were documented.
+
+- BUG FIX: Makefiles: Pass CFLAGS at link-time so link-time optimization
+  actually happens.  Pointed out by Zoltan Puskas.
+
+- BUG FIX: If the first REM command to trigger was a RUN command, the banner
+  would not print.  This has been fixed.
+
+- BUG FIX: replace deprecated 'fgrep' with 'grep -F' (Jochen Sprickerhof)
+
+- BUG FIX: make "make test" depend on "make all" (Jochen Sprickerhof)
+
+- BUG FIX: make "REM ... SATISFY ... MSG foo" respect $DefaultColor.  Bug
+  reported by Gunther Reißig.
+
+- BUG FIX: Don't consider IFTRIG true if we could not compute a trigger date.
+  Bug noted by Gunther Reißig.
+
+* VERSION 4.0 Patch 3 - 2022-08-16
+
+- IMPROVEMENT: remind: add plain_body and calendar_body JSON keys in -pp...
+  output.
+
+- BUG FIX: tkremind: Don't create empty files called '&1' when creating
+  a new reminder.
+
+- BUG FIX: remind: Don't call signal-unsafe functions from signal handler
+
+* VERSION 4.0 Patch 2 - 2022-08-02
+
+- IMPROVEMENT: remind: Allow more forms of OMIT as per Ian! D. Allen's request:
+
+               OMIT Month [THROUGH Month]
+               OMIT Day Month [THROUGH Day Month]
+               OMIT Day Month Year [THROUGH Day Month Year]
+
+- BUG FIX: Make $T behave as documented, exactly like trigdate().  $T would
+  return '1989-12-31' rather than 0 if the trigger date was not valid.
+
+- BUG FIX: TkRemind: Fix resizing bug for a calendar with 6 rows.
+
+- DOCUMENTATION IMPROVEMENT: Improve TkRemind documentation; document use
+  of inotifywait if available.
+
+* VERSION 4.0 Patch 1 - 2022-06-03
+
+- IMPROVEMENT: Add $SuppressLRM system variable to suppress the UTF-8
+  Left-to-Right mark in "remind -c" output.
+
+- DOCUMENTATION FIX: Document the "q" sub-option to the "-p" option.
