+  Changes affecting current and future time stamps
+
+    Turks & Caicos' switch from US eastern time to UTC-4 year-round
+    did not occur on 2014-11-02 at 02:00.  It's currently scheduled
+    for 2015-11-01 at 02:00.  (Thanks to Chris Walton.)
+
+  Changes affecting past time stamps
+
+    Many pre-1989 time stamps have been corrected for Asia/Seoul and
+    Asia/Pyongyang, based on sources for the Korean-language Wikipedia
+    entry for time in Korea.  (Thanks to Sanghyuk Jung.)  Also, no
+    longer guess that Pyongyang mimicked Seoul time after World War II,
+    as this is politically implausible.
+
+    Some more zones have been turned into links, when they differed
+    from existing zones only for older time stamps.  As usual,
+    these changes affect UTC offsets in pre-1970 time stamps only.
+    Their old contents have been moved to the 'backzone' file.
+    The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
+    Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
+    Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
+    Indian/Mayotte.
+
+  Changes affecting commentary
+
+    The commentary is less enthusiastic about Shanks as a source,
+    and is more careful to distinguish UT from UTC.
