+* VERSION 6.1 Patch 4 - 2025-10-08
 
 - BUG FIX: remind: In calendar mode, reminders that specify a TZ zone
   that is *behind* the system time zone could sometimes not show up.
   The bug has been fixed; thanks to Jin Chen for reporting it.
 
+- CHANGE: remind: Any time Remind runs another program (for example,
+  in response to REM ... RUN, the shell() command, the -k option, or
+  INCLUDECMD) it connects that command's standard input to /dev/null
+  so that it cannot interfere with the main Remind process's standard
+  input.
+
 - BUG FIX: remind: Don't set up an inotify file descriptor if we are
   not running in Daemon Mode.
 
+- MINOR IMPROVEMENT: remind: When using readline to read from a
+  terminal, include the line number in the Remind> prompt.
+
 - IMPROVEMENT: lang/*.rem: Suppress redefined function warnings if you
   include one language file and then later on a different one.
 
+- IMPROVEMENT: remind: Make the output of "make test" slightly more
+  verbose; color-code the PASS and FAIL results if standard output
+  refers to a terminal.
+
 - CHANGE: include/holidays/*.rem: Add %"..%" markers and %! %b
   suffixes to all reminders.  This prevents you from having to use the
-  msgsuffix() hack if you want advance warning of holidays.  See
