+Release 2016i - 2016-11-01 23:19:52 -0700
+
+ Briefly: Cyprus split into two time zones on 2016-10-30, and Tonga
+ reintroduces DST on 2016-11-06.
+
+ Changes to future time stamps
+
+ Pacific/Tongatapu begins DST on 2016-11-06 at 02:00, ending on
+ 2017-01-15 at 03:00. Assume future observances in Tonga will be
+ from the first Sunday in November through the third Sunday in
+ January, like Fiji. (Thanks to Pulu ʻAnau.) Switch to numeric
+ time zone abbreviations for this zone.
+
+ Changes to past and future time stamps
+
+ Northern Cyprus is now +03 year round, causing a split in Cyprus
+ time zones starting 2016-10-30 at 04:00. This creates a zone
+ Asia/Famagusta. (Thanks to Even Scharning and Matt Johnson.)
+
+ Antarctica/Casey switched from +08 to +11 on 2016-10-22.
+ (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Several corrections were made for pre-1975 time stamps in Italy.
+ These affect Europe/Malta, Europe/Rome, Europe/San_Marino, and
+ Europe/Vatican.
+
+ First, the 1893-11-01 00:00 transition in Italy used the new UT
+ offset (+01), not the old (+00:49:56). (Thanks to Michael
+ Deckers.)
+
+ Second, rules for daylight saving in Italy were changed to agree
+ with Italy's National Institute of Metrological Research (INRiM)
+ except for 1944, as follows (thanks to Pierpaolo Bernardi, Brian
+ Inglis, and Michael Deckers):
+
+ The 1916-06-03 transition was at 24:00, not 00:00.
+
+ The 1916-10-01, 1919-10-05, and 1920-09-19 transitions were at
+ 00:00, not 01:00.
+
+ The 1917-09-30 and 1918-10-06 transitions were at 24:00, not
+ 01:00.
+
+ The 1944-09-17 transition was at 03:00, not 01:00. This
+ particular change is taken from Italian law as INRiM's table,
+ (which says 02:00) appears to have a typo here. Also, keep the
+ 1944-04-03 transition for Europe/Rome, as Rome was controlled by
+ Germany then.
+
+ The 1967-1970 and 1972-1974 fallback transitions were at 01:00,
+ not 00:00.
+
+ Changes to code
+
+ The code should now be buildable on AmigaOS merely by setting the
+ appropriate Makefile variables. (From a patch by Carsten Larsen.)
+
+
