* Changes in Specialized Modes and Packages in Emacs 24.4
+** Calc
+
+*** Calc by default now uses the Gregorian calendar for all dates, and
+uses January 1, 1 AD as its day number 1. Previously Calc used the
+Julian calendar for dates before September 14, 1752, and it used
+December 31, 1 BC as its day number 1; the new scheme is more
+consistent with Calendar's calendrical system and day numbering.
+
+*** The new variable `calc-gregorian-switch' lets you configure the
+date when Calc switches from the Julian to the Gregorian calendar.
+Nil, the default value, means to always use the Gregorian calendar.
+The value (YEAR MONTH DAY) means to start using the Gregorian calendar
+on the given date.

** New function `ses-rename-cell' to give SES cells arbitrary names.
