+  - Egypt will not observe DST in 2015 and will consider canceling it
+    permanently.  For now, assume no DST indefinitely.
+  - The abbreviations for Hawaii-Aleutian standard and daylight times
+    have been changed from HAST/HADT to HST/HDT, as per US Government
+    Printing Office style.  This affects only America/Adak since 1983,
+    as America/Honolulu was already using the new style.
