 CHANGES TO REMIND
 
+* 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
