+\begin{itemize}
+\item Bad Dates: Christian Boesch alerted me to some date-formatting
+  errors produced when using the styles with the \texttt{german}
+  option to \textsf{babel}.  A little further investigation revealed
+  similar problems with \texttt{french}, and before long it became
+  clear that date handling in \textsf{biblatex-chicago} was generally,
+  and significantly, sub-optimal.  The whole system should now be more
+  robust and more accurate.
+\item The new date-handling code shouldn't require any changes to your
+  .bib files, but users of the author-date style may want to have a
+  look at the documentation of the \textsf{letter} and \textsf{misc}
+  entry types, and of the four date fields, for some information about
+  how the changes could simplify the creation of their databases.
+\item Various other minor improvements.
