The 2020c release of the tz code and data is available. It reflects the 
following changes, which were either circulated on the tz mailing list or are 
relatively minor technical or administrative changes:

   Briefly:
     Fiji starts DST later than usual, on 2020-12-20.

   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.
     (Problem reported by Mike Cullinan.)
