+        - Saving or discarding versions failed if a transaction that
+          added a new object in the version was undone.

+        - There was circumstantial evidence that a failure of an OS to
+          correctly delay writing to data to disk after Zope had
+          written it led to a corrupted database.  Zope now makes an
+          'fsync' system call (where available on Unix systems) to
+          force data to be written to phusical storage when
+          transactions are committed.
+
+        - Some applicataions were writing empty transactions. The
+          FileStorage now checks for and avoids writing empty
+          transactions in this case.
