 CHANGES TO REMIND

-* VERSION 6.0 Patch 0 - 2025-??-??
+* VERSION 6.1 Patch 2 - 2025-09-19
+
+- BUG FIX: remind: A reminder on a specific fixed date and time that
+  uses the TZ feature could erroneously issue a "Can't compute trigger"
+  error.  This has been fixed.
+
+- CHANGE: remind: The default for --max-expr-complexity is 10,000,000
+  (ten million) instead of unlimited.  This should not affect any
+  real-world Remind scripts.
+
+* VERSION 6.1 Patch 1 - 2025-09-12
+
+- NEW FEATURE: remind: Add the new --max-expr-complexity=n
+  command-line argument.  It is possible to write expressions that use
+  enormous amounts of CPU time, such as the following:
+
+          FSET fib(n) iif(n <= 2, 1, fib(n-1)+fib(n-2))
+          SET a fib(100)
+
+  That will take essentially forever to execute, but will not hit the
+  built-in recursion limit.  Using a command-line argument of
+  --max-expr-complexity=1000000 will terminate evaluation in a few
+  dozen milliseconds on modern hardware, and should not affect
+  realistic reminder scripts.  See the man page for details.
+
+- IMPROVEMENT: remind: Add UTF-8-aware functions to complement the
+  byte-aware functions that could give incorrect results by splitting
+  a UTF-8 character sequence.  The correspondence between old and new
+  functions is:
+
+     NON-UTF-8-AWARE   UTF-8-AWARE
+     ===============   ===========
+     strlen            mbstrlen
+     substr            mbsubstr
+     index             mbindex
+     char              mbchar
+     asc               codepoint
+
+  See the remind(1) man page for details.
+
+- MINOR NEW FEATURE: remind: You can use hexadecimal integer constants
+  like 0xFE12 in expressions.  This is mostly useful for using
+  codepoint() since Unicode code points are often expressed in
+  hexadecimal.
+
+- BUG FIX: remind: When truncating a string when executing DUMPVARS or
+  during debugging of expression evaluation, Remind could sometimes
+  cut the string in the middle of a UTF-8 sequence.  This has been
+  fixed.
+
+* VERSION 6.1 Patch 0 - 2025-09-08
+
+- MAJOR NEW FEATURE: remind: The TZ keyword lets you specify a time
+  zone for a REM command.  All trigger calculations are performed in
+  the named time zone.
+
+- DOCUMENTATION: Update README.md to document prerequisites for readline
+  support.
+
+- DOCUMENTATION: remind.1: Document system variables such as $T that can
+  have multiple types.
+
+- BUG FIX: remind: If Remind was run interactively ("remind -c -" with
+  readline support enabled) it would not properly cache the input
+  file, but would keep asking for interactive input.  This has been
+  fixed.
+
+* VERSION 6.0 Patch 2 - 2025-09-01
+
+- CHANGE: Default $ParseUntriggered to 0 instead of 1.  The default
+  could cause spurious warnings such as "type mismatch" warnings for
+  untriggered reminders.
+
+- TEST FIX: Explicitly set latitude and longitude in test files.
+
+- BUG FIX: remind: Don't add lines to "readline" history unless they
+  are actually being read from standard input.
+
+- BUG FIX: remind: On the command-line, make '-i$foo' behave the same
+  way as '-i$foo=0' as was documented in the man page.
+
+- BUG FIX: remind: Clamp the output of trigger() to "1 January 1990 AT
+  00:00" if the UTC flag is used, even if it would actually produce a
+  result in 1989.
+
+- MINOR FIX: remind: Avoid "unused result" compiler warning.
+
+* VERSION 6.0 Patch 1 - 2025-08-19
+
+- NEW FEATURE: remind: Add readline support if input is taken from stdin
+  (ie, "remind -").  This gives you full editing support if you run
+  Remind interactively.
+
+- BUG FIX: remind: Fix buffer overflow in DUMPVARS command.
+  Thanks to Jochen Sprickerhof for helping me find this bug.
