💣 Incompatible Changes
=======================
-#. N/A
+#. `@rcomer`_ and `@bjlittle`_ (reviewer) updated Iris's calendar handling to be
+ consistent with ``cf-units`` version 3.1. In line with the `Calendar`_
+ section in version 1.9 of the CF Conventions, we now use "standard" rather
+ than the deprecated "gregorian" label for the default calendar. Units may
+ still be instantiated with ``calendar="gregorian"`` but their calendar
+ attribute will be silently changed to "standard". This may cause failures in
+ code that explicitly checks the calendar attribute. (:pull:`4847`)
