 CHANGES TO REMIND
 
+* Version 3.1 Patch 7 - 2009-05-31
+
+- ENHANCEMENT: Wherever you could write "day Mon year", the parser now
+  accepts "YYYY-MM-DD".  This applies on the command-line and to the
+  REM and OMIT keywords.  You can avoid wrapping date calculations in
+  the trigger() function in many cases.
+
+- ENHANCEMENT: New slide() built-in function eases some complicated reminders.
+
+* Version 3.1 Patch 6 - 2008-11-16
+
+- MAJOR ENHANCEMENT: A new OMITFUNC clause gives you additional
+  control and flexibility over "omitted days" calculations.  This is
+  useful when holidays influence the timing of events several days
+  later.  See "COMPUTED LOCAL OMITS" in the man page.
+
+- ENHANCEMENT: The new evaltrig() built-in function lets you evaluate triggers
+  from within an expression.
+
+- ENHANCEMENT: The new weekno() built-in function returns the ISO 8601
+  week number of a date.
+
+- ENHANCEMENT: The "WEEK" special lets you annotate calendar output with the
+  week number.  The TkRemind, rem2ps and rem2html back-ends support WEEK.
+
+- MINOR ENHANCEMENT: You can control whether timed reminders come before or
+  after non-timed reminders with the "-g" flag.
+
+- BUG FIX: TkRemind did not work correctly if ~/.reminders was a directory.
+
+- BUG FIX: TkRemind incorrectly invoked Remind with the "-a" flag when
+  showing today's reminders.
+
+- BUG FIX: In certain cases, a trigger containing a day, month and
+  weekday would fail if it needed to cross a year boundary.  This has
+  been fixed.
+
 * Version 3.1 Patch 5 - 2008-04-15
 
 - MAJOR ENHANCEMENT: If you supply a directory name on the command line

+.B COMPUTED LOCAL OMITS
+.PP
+The \fBOMITFUNC\fR phrase of the \fBREM\fR command allows you to
+supply a function that determines whether or not a date is omitted.
+The function is passed a single parameter of type \fBDATE\fR, and must
+return a non-zero integer if the date is considered "omitted" and 0
+otherwise.  Here's an example:
+.PP

+In the example above, the reminder is triggered every Monday to Friday whose
+day-of-month number is divisible by three.  Here's how it works:
+.TP
+.B o
+The \fBOMITFUNC _third\fR portion causes all days for which \fB_third(x)\fR
+returns non-zero to be considered "omitted".  This causes all days whose
+day-of-month number is \fInot\fR a multiple of three to be omitted.  Note
+that _third also returns non-zero if the weekday is Sunday or Saturday.
+.TP
+.B o
+The \fBAFTER\fR keyword causes the reminder to be moved after a block of
+omitted days.
+.PP
+The combination of OMITFUNC and AFTER keyword causes the reminder to
+be issued on all days whose day-of-month number is divisible by three,
+but not on Saturday or Sunday.
+.PP
+Note that if you use \fBOMITFUNC\fR, then a local \fBOMIT\fR is
+\fIignored\fR as are \fIall global OMITs\fR.  If you want to omit specific
+weekdays, your omit function will need to test for them specifically.  If
+you want to take into account the global \fBOMIT\fR context, then your omit
+function will need to test for that explicitly (using the \fBisomitted()\fR
+function.)
+.PP
+Note that an incorrect \fBOMITFUNC\fR might cause all days to be considered
+omitted.  For that reason, when \fBRemind\fR searches through omitted days,
