+Release 2018g - 2018-10-26 22:22:45 -0700
+
+ Briefly:
+ Morocco switches to permanent +01 on 2018-10-27.
+
+ Changes to future timestamps
+
+ Morocco switches from +00/+01 to permanent +01 effective 2018-10-27,
+ so its clocks will not fall back on 2018-10-28 as previously scheduled.
+ (Thanks to Mohamed Essedik Najd and Brian Inglis.)
+
+ Changes to code
+
+ When generating TZif files with leap seconds, zic no longer uses a
+ format that trips up older 32-bit clients, fixing a bug introduced
+ in 2018f. (Reported by Daniel Fischer.) Also, the zic workaround
+ for QTBUG-53071 now also works for TZif files with leap seconds.
+
+ The translator to rearguard format now rewrites the line
+ "Rule Japan 1948 1951 - Sep Sat>=8 25:00 0 S" to
+ "Rule Japan 1948 1951 - Sep Sun>=9 1:00 0 S".
+ This caters to zic before 2007 and to Oracle TZUpdater 2.2.0
+ and earlier. (Reported by Christos Zoulas.)
+
+ Changes to past time zone abbreviations
+
+ Change HDT to HWT/HPT for WWII-era abbreviations in Hawaii.
+ This reverts to 2011h, as the abbreviation change in 2011i was
+ likely inadvertent.
+
+ Changes to documentation
+
+ tzfile.5 has new sections on interoperability issues.
+
+
