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

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

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.
