+  Compatibility note
+
+    Starting with release 2016b, some data entries cause zic implementations
+    derived from tz releases 2005j through 2015e to issue warnings like
+    "time zone abbreviation differs from POSIX standard (+03)".
+    These warnings should not otherwise affect zic's output and can safely be
+    ignored on today's platforms, as the warnings refer to a restriction in
+    POSIX.1-1988 that was removed in POSIX.1-2001.  One way to suppress the
+    warnings is to upgrade to zic derived from tz releases 2015f and later.
