+Release 2018c - 2018-01-22 23:00:44 -0800
+
+  Briefly:
+  Revert Irish changes that relied on negative DST offsets.
+
+  Changes to tm_isdst
+
+    Revert the 2018a change to Europe/Dublin.  As before, this change
+    does not affect UT offsets or abbreviations; it affects only
+    whether timestamps are considered to be standard time or
+    daylight-saving time, as expressed in the tm_isdst flag of C's
+    struct tm type.  This reversion is intended to be a temporary
+    workaround for problems discovered with downstream uses of
+    releases 2018a and 2018b, which implemented Irish time by using
+    negative DST offsets in the Eire rules of the 'europe' file.
+    Although negative DST offsets have been part of tzcode for many
+    years and are supported by many platforms, they were not
+    documented before 2018a and ICU and OpenJDK do not currently
+    support them.  A mechanism to export data to platforms lacking
+    support for negative DST is planned to be developed before the
+    change is reapplied.  (Problems reported by Deborah Goldsmith and
+    Stephen Colebourne.)
+
+  Changes to past time stamps
+
+    Japanese DST transitions (1948-1951) were Sundays at 00:00, not
+    Saturdays or Sundays at 02:00.  (Thanks to Takayuki Nikai.)
+
+  Changes to build procedure
+
+    The build procedure now works around mawk 1.3.3's lack of support
+    for character class expressions.  (Problem reported by Ohyama.)
+
+
+Release 2018b - 2018-01-17 23:24:48 -0800
+
+  Briefly:
+  Fix a packaging problem in tz2018a, which was missing 'pacificnew'.
+
+  Changes to build procedure
+
+    The distribution now contains the file 'pacificnew' again.
+    This file was inadvertantly omitted in the 2018a distribution.
+    (Problem reported by Matias Fonzo.)
