+- Issue #28253: Fixed calendar functions for extreme months: 0001-01
+  and 9999-12.
+
+  Methods itermonthdays() and itermonthdays2() are reimplemented so
+  that they don't call itermonthdates() which can cause datetime.date
+  under/overflow.
+
 - Issue #28275: Fixed possible use adter free in LZMADecompressor.decompress().
   Original patch by John Leitch.
