JDK-8260677 :  
TZ: 2020f - Closed
Description
The 2020f release of the tz code and data is available, reflecting the 
following change to the build procedure:

     'make rearguard_tarballs' no longer generates a bad rearguard.zi,
     fixing a 2020e bug.  (Problem reported by Deborah Goldsmith.)

There are no changes to the data since 2020e.

The build-procedure change was circulated on the tz mailing list and is 
intended for downstream consumers that can process only rearguard 
format. Please see the PS at the end of this email for more info about 
rearguard format.
