+* Mon Mar 14 2016 Patsy Franklin <pfrankli@redhat.com> - 2016b-1
+- Rebase to 2016b
+  - New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
+    Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04 on
+    2016-03-27 at 02:00 local time.  They need distinct zones since their
+    post-1970 histories disagree.  New zone Asia/Barnaul for Altai Krai and
+    Altai Republic, Russia, which will switch from +06 to +07 on the same date
+    and local time.  The Astrakhan change is already official; the others have
+    passed the first reading in the State Duma and are extremely likely.
+    Also, Asia/Sakhalin moves from +10 to +11 on 2016-03-27 at 02:00.
+  - As a trial of a new system that needs less information to be made up,
+    the new zones use numeric time zone abbreviations like "+04"
+    instead of invented abbreviations like "ASTT".
+  - Haiti will not observe DST in 2016.
+  - Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00.
+    Guess future transitions will be March's last
+    Saturday at 01:00, not March's last Friday at 24:00.
+
 * Thu Jan 28 2016 Patsy Franklin <pfrankli@redhat.com> - 2016a-1
 - Rebase to 2016a
   - America/Cayman will not observe daylight saving this year after all.
