-MICROSOFT WINDOWS
-=================
-
-I used to prohibit porting Remind to Microsoft Windows.  However, this
-may cause problems with the GPL, so I have removed that restriction.
-
-Although I cannot prevent you from porting Remind to Windows, I appeal
-to you not to do it.  I am trying to encourage the growth of free
-software, not proprietary software.
-
-If you port Remind to Windows, I will not provide support or answers to
-questions -- you're on your own.  On the other hand, I will feel no guilt
-in taking enhancements and merging them into the UNIX stream.
-
-APPLE
-=====
-
-I can't prevent you from using Remind on Apple's products, but I hope
-you don't.  Apple's corporate culture is the very antithesis of Free
-Software.  Rather than using Mac OS X, I encourage you to switch to
-Linux or FreeBSD, two Free Software operating systems that are every
-bit as capable as Mac OS X and which are unencumbered by Apple's
-arbitrary restrictions.
-
-And if you're looking to port Remind to other Apple products like the
-iPhone or iPad, please don't.  Those products enforce Apple's rigorous
-controls much more stringently than Mac OS X on an Apple PC.

+## How I use Remind and Google Calendar together
+
+  - My family has a Google Email domain, and our email addresses all end in the same domain. We all use Google Calendars and I want to mail reminders to each of the family members containing both Google Calendar and .reminder information.
+  - Under my ~/.rem/ directory each family member has a directory.  Each directory contains a standard remind file called 'reminders' that at the very least has the line "INCLUDE /home/jalcorn/.rem/<username>/ical2rem" and flag files indicating whether they want Daily or Weekly reminders.  My reminders files references my standard .reminders file, and I also have a flag so if I run a Test run I'll get it.  There's actually a lot more files (I have a big family).

+  - bin/getgooglecals.sh runs out of crontab and downloads whatever calendars I want. Note that we can also download organization calendars, I've included a public one here (Cleveland Heights Vocal Music Department calendar).
+  - dailyreminders.sh is linked to weeklyreminders.sh and testreminders.sh so I can run it in different modes. The concatenate the various calendar outputs as a single remind file then send the reminders via email.

+## Revision History
+### Version 0.7 2024-09-04
+  - ISSUE 8: New version of remind complains if _sfun isn't defined. Output a header
+	to define a function that does nothing if the function doesn't exist.
+### Version 0.6 2019-03-01
+  - Publish on GitHub and change license to MIT License
+  - Add supporting files and explanation of how I use it
+### version 0.5.2 2007-03-23
+      - BUG: leadtime for recurring events had a max of 4 instead of DEFAULT_LEAD_TIME
+      - remove project-lead-time, since Category was a non-standard attribute
+      - NOTE: There is a bug in iCal::Parser v1.14 that causes multiple calendars to
+              fail if a calendar with recurring events is followed by a calendar with no
+              recurring events.  This has been reported to the iCal::Parser author.
+### version 0.5.1 2007-03-21
+      - BUG: Handle multiple calendars on STDIN
+      - add --heading option for priority on section headers
+### version 0.5 2007-03-21
+      - Add more help options
+      - --project-lead-time option
+      - Supress printing of heading if there are no todos to print
+### version 0.4
+      - Version 0.4 changes all written or inspired by, and thanks to Mark Stosberg
+      - Change to GetOptions
+      - Change to pipe
+      - Add --label, --help options
+      - Add Help Text
+      - Change to subroutines
+      - Efficiency and Cleanup
+### version 0.3
+      - Convert to GPL (Thanks to Mark Stosberg)
+      - Add usage
+### version 0.2
+      - add command line switches
+      - add debug code
+      - add SCHED _sfun keyword
+      - fix typos
+### version 0.1 - ALPHA CODE.

+=head1 SYNOPSIS
+
+ cat /path/to/file*.ics | ical2rem.pl > ~/.ical2rem
+
+ All options have reasonable defaults:
+ --label           Calendar name (Default: Calendar)
+ --start               Start of time period to parse (parsed by str2time)
+ --end                 End of time period to parse
+ --lead-time           Advance days to start reminders (Default: 3)
+ --todos, --no-todos   Process Todos? (Default: Yes)
+ --iso8601             Use YYYY-MM-DD date format
+ --locations, --no-locations  Include location? (Default: Yes)
+ --end-times, --no-end-times  Include event end times in reminder text
+                              (Default: No)
+ --heading             Define a priority for static entries
+ --help            Usage
+ --debug           Enable debug output
+ --man             Complete man page
+
+Expects an ICAL stream on STDIN. Converts it to the format
+used by the C<remind> script and prints it to STDOUT. 
+
+=head2 --label
+
+  ical2rem.pl --label "Bob's Calendar"
+
+The syntax generated includes a label for the calendar parsed.
+By default this is "Calendar". You can customize this with 
+the "--label" option.
+
+=head2 --iso8601
+
+Use YYYY-MM-DD date format in output instead of Mmm DD YYYY
+
+=head2 --locations, --no-locations
+
+Whether or not to include locations in events
+
+=head2 --lead-time 
+
+  ical2rem.pl --lead-time 3
+ 
+How may days in advance to start getting reminders about the events. Defaults to 3. 
+
+=head2 --no-todos
+
+  ical2rem.pl --no-todos
+
+If you don't care about the ToDos the calendar, this will surpress
+printing of the ToDo heading, as well as skipping ToDo processing. 
+
+=head2 --heading
+
+  ical2rem.pl --heading "PRIORITY 9999"
+
+Set an option on static messages output.  Using priorities can made the static messages look different from
+the calendar entries.  See the file defs.rem from the remind distribution for more information.

-=head1 SYNOPSIS
-
- cat /path/to/file*.ics | ical2rem.pl > ~/.ical2rem
-
- All options have reasonable defaults:
- --label		       Calendar name (Default: Calendar)
- --lead-time	       Advance days to start reminders (Default: 3)
- --todos, --no-todos   Process Todos? (Default: Yes)
- --heading			   Define a priority for static entries
- --help				   Usage
- --man				   Complete man page
-
-Expects an ICAL stream on STDIN. Converts it to the format
-used by the C<remind> script and prints it to STDOUT. 
-
-=head2 --label
-
-  ical2rem.pl --label "Bob's Calendar"
-
-The syntax generated includes a label for the calendar parsed.
-By default this is "Calendar". You can customize this with 
-the "--label" option.
-
-=head2 --lead-time 
-
-  ical2rem.pl --lead-time 3
- 
-How may days in advance to start getting reminders about the events. Defaults to 3. 
-
-=head2 --no-todos
-
-  ical2rem.pl --no-todos
-
-If you don't care about the ToDos the calendar, this will suppress
-printing of the ToDo heading, as well as skipping ToDo processing. 
-
-=head2 --heading
-
-  ical2rem.pl --heading "PRIORITY 9999"
-
-Set an option on static messages output.  Using priorities can made the static messages look different from
-the calendar entries.  See the file defs.rem from the remind distribution for more information.

 CHANGES TO REMIND
 
+* VERSION 5.0 Patch 7 - 2024-10-16
+
+- NEW FEATURE: tkremind: Add option to create a desktop notification when
+  a queued reminder is triggered.  For Tcl/Tk 9.0 or later, uses the native
+  "tk sysnotify" facility.  For earlier versions of Tcl/Tk, executes the
+  "notify-send" program if possible.
+
+- NEW FEATURE: remind: Add --print-config-cmd option which prints the
+  exact ./configure command used to build Remind.  This will let you
+  configure future Remind releases exactly the same way an installed
+  version was configured.
+
+- UPDATE: include/holidays/ca.rem: Add National Day for Truth and
+  Reconciliation to Canadian holiday list.
+
+- MINOR IMPROVEMENTS: Update examples/ansitext and examples/astro
+
+- MINOR IMPROVEMENT: remind: Use HashPJW to hash variable and function
+  names; make the hash table size a prime rather than a power of two.
+  This seems to improve hash performance ever so slightly in most cases.
+
+- UPDATE: Update contrib/ical2rem to upstream version 0.7.1
+
+- FIX: tkremind: Make tkremind work with Tcl/Tk 8.5 or higher, including
+  Tcl/Tk 9.0
+
+- MINOR CHANGE: remind: Add hash table statistics to "-ds" debugging
+  output.  This is probably of no use to anyone except the author of
+  Remind.
+
+* VERSION 5.0 Patch 6 - 2024-09-16
+
+- NEW FEATURE: remind: Include a file containing the dates of Chinese
+  New Year through 2050.
+
+- NEW FEATURE: remind: Add $SuppressImplicitWarnings system variable.
+  Setting this to 1 suppresses the warnings "Unrecognized command;
+  interpreting as REM" and "Missing REM type; assuming MSG"
+
+- NEW FEATURE: remind: Add --print-tokens command-line argument.  This
+  simply prints all of Remind's built-in tokens, functions, and system
+  variables.  It's designed to help people who are writing editor
+  add-ons for syntax highlighting.
+
+- CHANGE: remind: allow '12:34' to be parsed as a TIME constant.  This
+  matches DATEs and DATETIMEs which are enclosed in single-quotes.
+  (The quotes are optional for TIME constants, however.)
+
+- IMPROVEMENT: Improve many error messages and warnings.
+
+- UPDATE: contrib/ical2rem: Update to upstream version 0.7
+
+- IMPROVEMENT: contrib/remind-conf-mode: Improve the Emacs
+  remind-conf-mode package.  Add new keywords and make comment
+  highlighting correct.
+
+- FIX: remind man page: Remove note saying REM can be omitted.
+
+* VERSION 5.0 Patch 5 - 2024-09-02
+
+- CHANGE: remind: When using the "-c" option and with the SHADE special
+  enabled, shade the entire calendar box including the line containing the
+  day number.
+
+- IMPROVEMENT: remind: Better error messages when diagnosing certain
+  errors in expressions.
+
+- IMPROVEMENT: include/holidays/jewish.rem: Remove unnecessary _h()
+  function definition.
+
+- BUG FIX: remind: In a couple of spots when we parsed a character, we did
+  not check for an error return.  This has been fixed.
+
+- BUG FIX: remind: Fix edge-case bugs in "remind -c" output formatting.
+
+- BUG FIX: make test: Fix a test that was broken for all of September 2024.
+
+- BUG FIX: remind: Fix a couple of potential file-descriptor leaks.
+
+- BUG FIX: contrib/ical2rem.pl: Replace "SCHED _sfun" with "+15" to
+  hard-code 15-minutes advance warning rather than using an undefined
+  scheduling function.  If this is not what you want, you should edit
+  ical2rem.pl to suit your taste; it's not officially part of Remind and
+  is meant more as a starting point for you to customize than a finished
+  product.
+
+- DOCUMENTATION FIX: Remove obsolete info from Remind man page.
+
+* VERSION 5.0 Patch 4 - 2024-08-29
+
+- IMPROVEMENT: remind: When checking if a SATISFY expression refers to the
+  trigger date, look recursively at any user-defined functions it calls.
+  This reduces spurious warnings.
+
+- CHANGE: remind: Allow any type to be used as the test argument for IIF.
+
+- IMPROVEMENT: remind man page: Clarify how various types are treated
+  in boolean context.
+
+* VERSION 5.0 Patch 3 - 2024-08-28
+
+- IMPROVEMENT: remind: Preserve newlines ("%_" sequences) in calendar
+  mode in most cases.  See the remind man page for details.
+
+- IMPROVEMENT: rem2pdf: rem2pdf can now produce PostScript and
+  Encapsulated PostScript output in addition to PDF and SVG.
+
+- IMPROVEMENT: remind: Emit warnings if a subst_XXX function takes the
+  wrong number of arguments, or for custom sequences, if the function
+  is not defined.
+
+- IMPROVEMENT: remind: Emit warnings if WARN/SCHED/OMITFUNC functions
+  do not reference their argument.
+
+- IMPROVEMENT: remind: Allow strings to be used with logical
+  operators.  The empty string "" is considered false and all other
+  strings are considered true.
+
+- IMPROVEMENT: remind: Emit warnings for lines that are implicitly
+  treated as REM commands; add warnings for REM commands that are
+  implicitly treated as MSG-type reminders.
+
+- IMPROVEMENT: remind: Add an optional fourth argument to the built-in
+  ampm() function that specifies not to suppress a leading zero in the
+  hour component.
+
+- IMPROVEMENT: remind: If a SATISFY expression is not constant and
+  doesn't reference the trigger date somehow, issue a warning.
+
+- IMPROVEMENT: remind: Add a warning if a user-defined function is
+  redefined.  If you do have a use-case that requires you to redefine
+  a function, simply FUNSET it first before FSETting it for the second
+  time.
+
+- DOCUMENTATION FIX: Clarify man pages and remove some information that
+  has become incorrect as Remind has evolved.
+
+- BUG FIX: Fix typos in man pages
+
+* VERSION 5.0 Patch 2 - 2024-07-26
+
+- IMPROVEMENT: Remind: Revamp how ONCE works.  You can now set a
+  special variable $OnceFile to be the path to a timestamp file.  The
+  ONCE directive uses this timestamp file to track when it was last
+  run rather than the access date of the main reminder script.  This
+  is more reliable because it doesn't rely on the atime of a file
+  (which might not be maintained accurately) and is not affected if
+  you edit your reminder script.
+
+- CHANGE: Taking input from stdin no longer implies the "-o" option; ONCE can
+  work if you set $OnceFile
+
+- CHANGE: Any of the -c, -n, -p and -s options implicitly enable the
+  -o option.  As before, specifying a repeat factor *N or a date that
+  is not today on the command-line also implies -o.
+
+- MINOR NEW FEATURE: Rem2PDF: Add the "--svg" command-line option to produce
+  SVG output rather than PDF.
+
+- MINOR IMPROVEMENT: Remind: Improve the storage efficiency of short
+  string constants in compiled expression trees.
+
+- MINOR IMPROVEMENT: Remind: Remove some obsolete macro definitions
+
+* VERSION 5.0 Patch 1 - 2024-06-08
+
+- MINOR IMPROVEMENT: Add short-circuit evaluation to the isany() function,
+  which now only evaluates those arguments absolutely necessary to determine
+  the result.
+
+- BUG FIX: Mark weekno() as a non-constant function (the zero-argument form
+  depends on external conditions.)
+
+- BUG FIX: Fix a couple of memory leaks.
+
+- BUG FIX: Don't rely on support for unnamed function parameters; this caused
+  compilation failures with older versions of gcc.
+
+* VERSION 5.0 Patch 0 - 2024-06-06
+
+- MAJOR CHANGE: The expression evaluation engine has been completely replaced
+  with a new one that splits parsing and evaluating into two separate steps.
+  It also features short-circuit evaluation of &&, ||, iif() and choose().
+  This should speed up expression-heavy reminder files.
+
+  NOTE INCOMPATIBILITY: In expressions with side-effects, the short-circuit
+  evaluation might change the result you get.  For example, consider
+  running the following file through: remind file.rem 2024-06-04
+
+    SET a trig("Mon +7") || trig("Thu +7")
+    MSG trig = [trig()]
+
+  Older Remind versions will output:
+
+    trig = 2024-06-06
+
+  whereas this version outputs:
+
+    trig = 2024-06-10
+
+  because the second part of the "||" expression is not evaluated.  The vast
+  majority of Remind expressions do not have side-effects and should yield
+  the same results as before.
+
+  The newer expression engine also permits recursive functions, but
+  these are not recommended.  Still, if you want to, you can do:
+
+    fset factorial(n) iif(n <= 1, 1, n*factorial(n-1))
+
+  and it will work for values of n that don't cause integer overflow.
+
+- IMPROVEMENT: If there's an unmatched PUSH-OMIT-CONTEXT, print the
+  filename and line number containing it.
+
+- IMPROVEMENT: If there's an IF with a missing ENDIF, print the filename
+  and line number of the IF statement.
+
+- NEW FEATURE: Add EXPR OFF command to completely disable expression
+  evaluation.  Useful if you INCLUDE files that you don't expect to
+  contain expressions and may come from slightly untrustworthy sources.
+
+- NEW FEATURE: Add $ExpressionTimeLimit system variable to enforce a
+  maximum limit on how long evaluating an expression is allowed to take.
+
+- NEW FEATURE: Add --max-execution-time=n command-line option to terminate
+  Remind if it runs for more than n seconds.
+
+- CHANGE: Make the command-line option "-ifoo" equivalent to "-ifoo=0"
+
+- CHANGE: Permit a literal [ in a reminder by using the sequence [[
+  The old ["["] still works.
+
+- BUG FIX: In "purge" mode, Remind would sometimes purge reminders with
+  a relative "SCANFROM" which haven't actually expired.  This has been fixed.
+
+- BUG FIX: Disallow something like: FSET func(x, x) expr
+  which shouldn't have been allowed in the first place.
+
+- BUG FIX: Replace leading spaces with tabs in Makefiles (per Emanuele Torre
+  and Tim Chase)
+
+* VERSION 4.3 Patch 7 - 2024-04-29
+
+- IMPROVEMENT: build.tk: Add a note if build.tk obtains default settings
+  from an existing Remind installation.
+
+- IMPROVEMENT: configure: Pass all args to AC_INIT including the Remind
+  home page.  Remove some unused autoconf cruft.
+
+- IMPROVEMENT: Use standard C library versions of strdup, strcasecmp and
+  strncasecmp where available, rather than using our own versions.
+
+- MINOR FEATURE: remind: Make $Tt a synonym for trigtime().
+
+- BUG FIX: remind: Make sure shellescape() doesn't mangle UTF-8 characters
+  with high-bits set.
+
+- BUG FIX: remind: Don't rely on undefined behavior of "%" operator in
+  the ord() built-in function.
+
+- BUG FIX: remind: Do not clear out trigtime() unnecessarily.  Before,
+  you could not write things like the following; now you can:
+
+      REM Tue AT 11:30 DURATION 0:30 MSG Thing 1
+      REM Tue AT [trigtime()+trigduration()] DURATION 1:00 MSG Thing 2
+      REM Tue AT [trigtime()+trigduration()] DURATION 0:45 MSG Thing 3
+
+  for successive reminders that should be moved as a block if the time of
+  the first one changes.
+
+- BUG FIX: Don't update trigdate() or trigtime() while parsing a REM
+  statement... only when actually computing the trigger.
+
+* VERSION 4.3 Patch 6 - 2024-04-02
+
+- NEW FILE: Add [$SysInclude]/holidays/pt.rem - Portuguese holidays, courtesy
+  of Joop Kiefte.
+
+- BUG FIX: remind: Fix compile error on systems that don't support inotify(7).
+
+- BUG FIX: remind: Fix test failures on FreeBSD.  On FreeBSD, you have to copy
+  the result of getenv() or else a subsequent setenv() can change the stored
+  value.
+
+* VERSION 4.3 Patch 5 - 2024-04-01
+
+- IMPROVEMENT: remind: Use inotify to detect reminder file changes
+  even in regular daemon mode (-zn where n>0).
+
+- INTERNAL IMPROVEMENTS: Rearrange and refactor some code.
+
+- FIXES: Various fixes and improvements to man pages.
+
+- BUG FIX: remind: Handle queued "SPECIAL COLOR" reminders correctly.
+
+- BUG FIX: remind: Preserve the value of $DefaultColor that was in effect
+  when a reminder was queued; restore it before issuing the queued reminder.
+
+* VERSION 4.3 Patch 4 - 2024-03-25
+
+- NEW FEATURE: remind: Add the new "multitrig" function, which is how "trig"
+  should have worked in the first place.  See man page for details.
+
+- IMPROVEMENT: tkremind: Make errors in your reminders file stand out more
+  prominently.
+
+- IMPROVEMENT: tkremind: If you click on an error in the "Errors..." popup,
+  tkremind will open a text editor on the offending file and line.
+
+- IMPROVEMENT: tkremind: Format the "Queue..." output better and make queue
+  items clickable; clicking on a queue item opens a text editor on the
+  corresponding file and line.
+
+- IMPROVEMENT: Add a standard [$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
