 CHANGES TO REMIND
 
+* VERSION 4.3 Patch 4 - 2024-03-25
+
+* NEW FEATURE: remind: Add the new "multitrig" function, which is how "trig"
+  should have worked in the first place.  See man page for details.
+
+* IMPROVEMENT: tkremind: Make errors in your reminders file stand out more
+  prominently.
+
+* IMPROVEMENT: tkremind: If you click on an error in the "Errors..." popup,
+  tkremind will open a text editor on the offending file and line.
+
+* IMPROVEMENT: tkremind: Format the "Queue..." output better and make queue
+  items clickable; clicking on a queue item opens a text editor on the
+  corresponding file and line.
+
+* IMPROVEMENT: Add a standard [$SysInclude]/moonphases.rem file to display
+  moon phases on your calendar.
+
+* IMPROVEMENT: Clean up the demo code in www/ and add PDF output.
+
+* BUG FIX: tkremind: Correctly handle filenames containing spaces and other
+  characters that tend to confuse the shell.
+
+* BUG FIX: tkremind: Raise dialog boxes after errors so that they
+  remain visible.
+
+* CLEANUP: tkremind: Remove some dead code.
+
+* VERSION 4.3 Patch 3 - 2024-03-18
+
+* IMPROVEMENT: tkremind: Update icon to include a white border so it shows
+  up better on dark backgrounds.
+
+* IMPROVEMENT: C code: Fix a number of cppcheck static-analysis warnings.
+
+* IMPROVEMENT: remind: Update the "-zj" protocol to include a queue-id for
+  each queued reminder and add the DEL client command to delete a specific
+  item from the queue.  Used by tkremind to implement "don't remind me about
+  this again today."
+
+* MINOR NEW FEATURE: Add a "-ds" debugging flag to print out expression-parsing
+  stack high-water marks on exit.  This esoteric feature is of no use to
+  anyone but the Remind author.
+
+* IMPROVEMENT: tkremind: Stop using the deprecated tk_dialog command in favor
+  of the newer tk_messageBox command.
+
+* IMPROVEMENT: remind: In server mode, try to minimize redraws by
+  consuming inotify events until at least 0.2s elapses without an
+  event appearing.
+
+* BUG FIX: tkremind:  The "Don't remind me about this again today" feature
+  was unreliable and only worked for reminders created with TkRemind itself.
+  It has been made more reliable and works with any reminder.
+
+* BUG FIX: remind: Make it a syntax error if a local OMIT in a REM statement
+  is not followed by at least one weekday name.
+
+* VERSION 4.3 Patch 2 - 2024-03-01
+
+- BUG FIX: remind: Fix a logic error when implementing the RUN command in
+  server mode.  As it turns out, the error is harmless, but it's best to do
+  things correctly.
+
+- BUG FIX: The Makefile would install the tkremind.png and tkremind.desktop
+  files in the wrong location.  This has been fixed.
+
+* VERSION 4.3 Patch 1 - 2024-02-29
+
+- BUG FIX: tests:  "make test" could fail because of a bad test.  This
+  has been fixed.  There are no actual code changes to any of the programs
+  in Remind compared to 04.03.00.
+
+* VERSION 4.3 Patch 0 - 2024-02-29
+
+- IMPROVEMENT: remind: If Remind is compiled on a system that supports
+  inotify, then in server mode (-z0 or -zj) it monitors the reminders file
+  and restarts itself if it detects a change, and also notifies the client.
+  Moving inotify support directly into Remind means that tkremind no longer
+  has to invoke a separate inotifywait process.
+
+- IMPROVEMENT: remind: Set the CLOEXEC flag on files we open so we
+  don't leak file descriptors to programs that we run.  While I don't
+  think there's a security issue here (any program you run can do
+  anything as your userid anyway) it's best to be clean and tidy.
+
+- IMPROVEMENT: remind: Add localization for the Catalan language, courtesy
+  of Eloi Torrents.
+
+- IMPROVEMENT: tkremind: Add a .desktop file and icon so TkRemind can be
+  integrated into the desktop menu system, courtesy of Eloi Torrents.
+
+- CHANGE: Add a new server mode with the "-zj" flag.  This is just
+  like "-z0" except it uses JSON messages to communicate with the
+  client rather than an ad-hoc protocol.  The "-z0" mode is still
+  supported, but is deprecated.
+
+- CHANGE: In server mode (-z0 or -zj) any RUN-type reminders, or message
+  commands of the "-kcommand" type are run with standard input and standard
+  output connected to /dev/null.  NOTE INCOMPATIBILITY: If you previously
+  relied on RUN-type reminders to pop up reminders in TkRemind, they no
+  longer do.  If you want this, you'll have to get the command that you
+  run to pop up its own window with "xmessage" or something similar.
+
+- IMPROVEMENT: tkremind: Make the "Go to date..." dialog non-modal.
+
+- CHANGE: remind: Allow the argument to easterdate() and
+  orthodoxeaster() to be omitted, in which case it defaults to
+  today().
+
+- BUG FIX: Miscellaneous man page fixes.
+
+- BUG FIX: Fix a leap-year edge-case.  The reminder: REM 29 MSG whatever
+  was not triggered on Feb 29 of leap years.
+
+- BUG FIX: rem2html: Make the version of rem2html track the version of
+  Remind.  Noted by Ian! D. Allen.
+
+* VERSION 4.2 Patch 9 - 2024-02-04
+
+- CHANGE: remind: Do not attempt to guess terminal background color on
+  startup.  Only obtain it as needed.  This can prevent mojibake from
+  appearing on terminals that don't support the color query escape
+  sequence.
+
+- IMPROVEMENT: remind: Add new system variables $NumFullOmits,
+  $MaxFullOmits, $NumPartialOmits and $MaxPartialOmits.
+
+- IMPROVEMENT: remind: Issue a warning if someone OMITs every possible date.
+
+- IMPROVEMENT: remind: In several error messages complaining about limits
+  being exceeded, include the actual limit in the error message.  Clarify
+  the man page regarding limits on the number of OMITs.
+
+- MINOR NEW FEATURE: remind:  The expression STRING * INT or INT * STRING
+  is now accepted and yields a string that is INT concatenations of the
+  original STRING.  In this case, INT must be non-negative and the total
+  string length can't exceed $MaxStringLen.
+
+- DOCUMENTATION: Add "Astronomical Algorithms" by Jean Meeus to bibliography.
+
+- DOCUMENTATION FIX: Update address of the Free Software Foundation in the
+  license file.
+
+- DOCUMENTATION: Note that rem2ps is deprecated and will not received any
+  new features.  Further development will happen on rem2pdf.
+
+- BUG FIX: Preserve the filename() and priority context for queued reminders.
+  Previously, the filename information was lost and the priority was
+  coming from uninitialized memory (yikes!).  bug found by Alexander
+  Möller.
+
+- BUG FIX: build.tk: Various minor improvements.
+
+- BUG FIX: remind: In server mode, if we de-queue a reminder without
+  triggering it, issue a "NOTE queued %d" message to update the
+  client's notion of the queue size.
+
+- BUG FIX: tkremind: Fix typo found by Lorenzo Bazzanini.
+
+* VERSION 4.2 Patch 8 - 2023-12-14
+
+- NEW FEATURE: Add the $MaxLateMinutes system variable.  This suppresses
+  a queued time reminder if the current time is more than $MaxLateMinutes
+  past the trigger time.  (This typically only occurs if the computer
+  has been suspended/hibernated and then resumed.)
+
+- IMPROVEMENT: tkremind: If an error occurs during printing, catch it
+  and change the Queue... button to Errors... (the same way errors in
+  reminder files are handled.)
+
+- IMPROVEMENT: rem2html: add the --utf8 flag to set the HTML charset to
+  UTF-8.
+
+- MINOR IMPROVEMENTS: Refactor some of the C code; use symbolic exit
+  statuses and file descriptors for stdin/stdout/stderr where possible.
+
+- BUG FIX: configure.in: Use better option detection so we don't use the
+  unsupported option -ffat-lto-objects if compiling with clang instead of gcc.
+
+- BUG FIXES: Many fixes to man pages, some by Jochen Sprickerhof
+
+- MINOR BUG FIX: If Remind puts itself in the background, only close
+  stdout/stderr if they are not associated with a terminal.  If
+  we close a descriptor, dup /dev/null onto it.
+
+- MINOR BUG FIX: Catch SIGCONT when running in daemon/background mode.
+  This forces the select() call to be interrupted so we can update the
+  sleep time.  This really only matters if the computer or the background
+  Remind process is suspended and then resumed.
+
+* VERSION 4.2 Patch 7 - 2023-10-09
+
+- IMPROVEMENT: remind: On 32-bit systems, attempt to use a 64-bit time_t
+  if the C library supports that.  This lets Remind work properly with
+  dates after 2038 in the few cases it has to call mktime() internally.
+
+- MINOR NEW FEATURE: remind: Attempt to obtain the terminal background
+  color using an OSC sequence.  This normally only happens if standard
+  output is a terminal, but can be forced with the '-@..,t' option.
+
+- MINOR NEW FEATURE: remind: Add "--version" long option to print out
+  Remind's version and exit.
+
+- MINOR IMPROVEMENT: tkremind: Use a higher-resolution PNG image for
+  the icon.
+
+- MINOR IMPROVEMENT: remind-conf-mode.el: Update highlighting rules
+  courtesy of Bill Benedetto
+
+- MINOR CHANGE: Make AT optional.  If we encounter a TIME in a REM
+  command, implicitly begin an AT clause.
+
+- DOCUMENTATION: Many minor fixes and improvements courtesy of Dan Jacobson.
+
+- BUG FIX: Make "-w0" set the calendar width based on standard output
+  rather than setting it to zero and causing an infinite loop.
+
+* VERSION 4.2 Patch 6 - 2023-09-12
+
+- NEW FEATURE: remind: The "nonomitted()" function takes an optional
+  extra INT argument called "step".  See man page for details.  Also
+  allows the "start" argument to be greater than the "end" argument,
+  in which case they are effectively swapped.
+
+- NEW FEATURE: remind: The "slide()" function takes an optional extra
+  INT argument called "step", similar to "nonomitted()".  See man page
+  for details.
+
+- NEW FEATURE: remind: Added the $ParseUntriggered system variable;
+  see the man page for details.  You almost certainly will never need
+  to use this.
+
+- NEW FILE: holidays/ie.rem: Added Irish holidays, courtesy of
+  Amy de Buitléir.
+
+- CHANGE: remind: The "-tn" option sets all REM statement deltas to
+  ++n rather than adding n to any existing REM statement's delta.
+  Additionally, the corresponding system variable $DeltaOffset has
+  been renamed to $DeltaOverride.
+
+- NEW OPTION: remind: Add the "-tz" option to explicitly set all
+  REM statement deltas to zero.
+
+- DOCUMENTATION FIX: remind: various documentation improvements.
+
+- BUG FIX: Correct some errors in Italian localization, courtesy of
+  Emanuele Torre
+
+* VERSION 4.2 Patch 5 - 2023-04-11
+
+- MINOR IMPROVEMENT: remind: If someone uses OMIT yyyy-mm-dd UNTIL yyyy-mm-dd
+  give a better error message suggesting THROUGH instead of UNTIL.
+
+- BUG FIX: remind: The fix for the combination of ADDOMIT and SATISFY that
+  appeared in version 04.02.00 was not complete; the bug has finally been
+  properly fixed.
+
+- BUG FIX: remind: Remove an unnecessary #include <sys/file.h>.
+  Nothing needed that and it broke compilation on FreeBSD.
+
+* VERSION 4.2 Patch 4 - 2023-03-15
+
+- NEW FEATURE: Remind: Add "htmlescape" and "htmlstriptags" built-in
+  functions.
+
+- NEW FEATURE: Rem2PDF: Add the "--wrap, -y" option to ensure that no
+  printed calendar takes up more than 5 rows.  If a calendar would normally
+  require 6 rows, wrap it so the last day or two appear on the first
+  row instead of on a sixth row.
+
+- NEW FEATURE: Remind: Improve the -k option to allow specification of
+  separate commands for immediately-issued vs. queued reminders.  For
+  example:
+
+     remind '-kcmd1 %s' '-k:cmd2 %s' ...
+
+  will use "cmd1" for immediately-issued reminders and "cmd2" for queued
+  ones.  If you only use '-k:cmd2 %s' then immediately-issued reminders
+  are simply printed as usual rather than being passed to a command.
+
+- IMPROVEMENT: Remind:  Make "SPECIAL MSG" the same as just "MSG" and
+  the same for MSF, RUN, PS and PSFILE.  This effectively lets you use
+  expression-pasting to determine the type of a REM command; see the
+  remind(1) man page for details.
+
+- MINOR IMPROVEMENT: If "make test" fails, output up to 200 lines of diff
+  so we can see immediately what failed.
+
+- DOCUMENTATION FIX: Fix some typos; fix TkRemind syntax description.
+
+- TEST FIX: Make tests run reliably regardless of local machine's time zone.
+
+- BUG FIX: TkRemind: Don't crash if local installation of Tk lacks the
+  -underlinefg configuration option.
+
+- BUG FIX: examples/defs.rem: Fix up US Thanksgiving example.
+
+- BUG FIX: include/holidays/us.rem: Add logic for US holidays that are
+  observed on a Friday if the holiday is a Saturday, or on a Monday if the
+  holiday is a Sunday.
+
+- BUG FIX: TkRemind: Don't cut off MOON text at the first white-space
+  character.
+
+- BUG FIX: Remind: prevent functions defined on the command-line (as in
+  remind '-if(x)=whatever') from segfaulting.
+
+* VERSION 4.2 Patch 3 - 2023-02-10
+
+- NEW FEATURE: Remind: add the orthodoxeaster() function to return the
+  date of Orthodox Easter.
+
+- IMPROVEMENT: Add Greek language support courtesy of JeiEl.
+
+- IMPROVEMENT: Add Greek holiday file courtesy of JeiEl.
+
+- IMPROVEMENT: Fix the Perl code (rem2pdf, rem2html) to silence Perl::Critic
+  warnings
+
+- IMPROVEMENT: Many internal code tweaks to eliminate many cppcheck
+  static analysis warnings.
+
+- DOCUMENTATION IMPROVEMENT: Clarify the distinction between a "time"
+  and a "duration" as suggested by Ian! D. Allen.
+
+- BUG FIX: Remind: Fix incorrect interaction between sortbanner() and
+  MSF-type reminders.  Bug found by Tim Chase.
+
+- BUG FIX: examples/defs.rem: Fix the calculation of US Tax Day as per
+  Tavis Ormandy and Tim Chase.  Also fixed in include/holidays/us.rem
+
+- BUG FIX: Remind: Add missing #include <fcntl.h> to funcs.c
+
+- BUG FIX: Remind: Fix undefined integer-overflow behavior in built-in abs()
+  function.  Pointed out on IRC by "ubitux".
+
+* VERSION 4.2 Patch 2 - 2023-01-01
+
+- NEW FEATURE: Remind: Add the NOQUEUE modifier to the REM statement for
+  explicitly telling Remind not to queue a timed reminder.
+
+- NEW FEATURE: Remind: Add soleq() function to return the DATETIME of
+  solstices and equinoxes.  See $SysInclude/seasons.rem for an example
+  of how to use the function.
+
+- MINOR IMPROVEMENT: Update examples/astro to include solstices and equinoxes.
+
+- BUG FIX: TkRemind: Provide better error indication if showing today's
+  reminders fails on startup.
+
+- BUG FIX: Remind: Refuse to read world-writable directories.
+
+- BUG FIX: Tests depended on the actual date of the test run.  This has
+  been fixed.
+
+- INTERNAL CHANGE: Remind: Change inappropriately-named "Julian" variables
+  to "DSE" (= Days Since Epoch) since they weren't really holding true
+  Julian dates.
+
+- INTERNAL CHANGE: Add "SPDX-License-Identifier" tags to most files.
+
+* 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 command-line option 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
