    From NEWS for release 2014b:

         Changes affecting code

        'zic' and 'localtime' no longer reject locations needing four 
transitions
         per year for the foreseeable future.  (Thanks to Andrew Main 
(Zefram).)

         Changes affecting near-future time stamps

         New entry for Troll station, Antarctica.  (Thanks to Paul-Inge 
Flakstad and
         Bengt-Inge Larsson.)  This is currently an approximation; a 
better version
         will require the zic and localtime fixes mentioned below, and 
the plan is
         to wait for a while until at least the zic fixes propagate.

    From Antarctica/Troll in 2023d;

       # The CET-switching Troll rules require zic from tz 2014b or 
later, so as
       # suggested by Bengt-Inge Larsson comment them out for now, and 
approximate
       # with only UTC and CEST.  Uncomment them when 2014b is more 
prevalent.
