   Changes to future timestamps
+
     Fiji will start DST on 2020-12-20, instead of 2020-11-08 as
     previously predicted.  DST will still end on 2021-01-17.
     (Thanks to Raymond Kumar and Alan Mintz.)  Assume for now that
     the later-than-usual start date is a one-time departure from the
     recent pattern.
 
+  Changes to build procedure

+    Rearguard tarballs now contain an empty file pacificnew.
+    Some older downstream software expects this file to exist.
