+Release 2019c - 2019-09-11 08:59:48 -0700
+
+  Briefly:
+    Fiji observes DST from 2019-11-10 to 2020-01-12.
+    Norfolk Island starts observing Australian-style DST.
+
+  Changes to future timestamps
+
+    Fiji's next DST transitions will be 2019-11-10 and 2020-01-12
+    instead of 2019-11-03 and 2020-01-19.  (Thanks to Raymond Kumar.)
+    Adjust future guesses accordingly.
+
+    Norfolk Island will observe Australian-style DST starting in
+    spring 2019.  The first transition is on 2019-10-06.  (Thanks to
+    Kyle Czech and Michael Deckers.)
+
+  Changes to past timestamps
+
+    Many corrections to time in Turkey from 1940 through 1985.
+    (Thanks to Oya VulaÅ? via Alois Treindl, and to Kıvanç Yazan.)
+
+    The Norfolk Island 1975-03-02 transition was at 02:00 standard
+    time, not 02:00 DST.  (Thanks to Michael Deckers.)
+
+    South Korea observed DST from 1948 through 1951.  Although this
+    info was supposed to appear in release 2014j, a typo inadvertently
+    suppressed the change.  (Thanks to Alois Treindl.)
+
+    Detroit observed DST in 1967 and 1968 following the US DST rules,
+    except that its 1967 DST began on June 14 at 00:01.  (Thanks to
+    Alois Treindl for pointing out that the old data entries were
+    probably wrong.)
+
+    Fix several errors in pre-1970 transitions in Perry County, IN.
+    (Thanks to Alois Triendl for pointing out the 1967/9 errors.)
+
+    Edmonton did not observe DST in 1967 or 1969.  In 1946 Vancouver
+    ended DST on 09-29 not 10-13, and Vienna ended DST on 10-07 not
+    10-06.  In 1945 Königsberg (now Kaliningrad) switched from +01/+02
+    to +02/+03 on 04-10 not 01-01, and its +02/+03 is abbreviated
+    EET/EEST, not CET/CEST.  (Thanks to Alois Triendl.)  In 1946
+    Königsberg switched to +03 on 04-07 not 01-01.
+
+    In 1946 Louisville switched from CST to CDT on 04-28 at 00:01, not
+    01-01 at 00:00.  (Thanks to Alois Treindl and Michael Deckers.)
+    Also, it switched from CST to CDT on 1950-04-30, not 1947-04-27.
+
+    The 1892-05-01 transition in Brussels was at 00:17:30, not at noon.
+    (Thanks to Michael Deckers.)
+
+  Changes to past time zone abbreviations and DST flags
+
+    Hong Kong Winter Time, observed from 1941-10-01 to 1941-12-25,
+    is now flagged as DST and is abbreviated HKWT not HKT.
+
+  Changes to code
+
+    leapseconds.awk now relies only on its input data, rather than
+    also relying on its comments.  (Inspired by code from Dennis
+    Ferguson and Chris Woodbury.)
+
+    The code now defends against CRLFs in leap-seconds.list.
+    (Thanks to Brian Inglis and Chris Woodbury.)
+
+  Changes to documentation and commentary
+
+    theory.html discusses leap seconds.  (Thanks to Steve Summit.)
+
+    Nashville's newspapers dueled about the time of day in the 1950s.
+    (Thanks to John Seigenthaler.)
+
+    Liechtenstein observed Swiss DST in 1941/2.
+    (Thanks to Alois Treindl.)
+
+
+Release 2019b - 2019-07-01 00:09:53 -0700
+
+  Briefly:
+    Brazil no longer observes DST.
+    'zic -b slim' outputs smaller TZif files; please try it out.
+    Palestine's 2019 spring-forward transition was on 03-29, not 03-30.
+
+  Changes to future timestamps
+
+    Brazil has canceled DST and will stay on standard time indefinitely.
+    (Thanks to Steffen Thorsen, Marcus Diniz, and Daniel Soares de
+    Oliveira.)
+
+    Predictions for Morocco now go through 2087 instead of 2037, to
+    work around a problem on newlib when using TZif files output by
+    zic 2019a or earlier.  (Problem reported by David Gauchard.)
+
+  Changes to past and future timestamps
+
+    Palestine's 2019 spring transition was 03-29 at 00:00, not 03-30
+    at 01:00.  (Thanks to Sharef Mustafa and Even Scharning.)  Guess
+    future transitions to be March's last Friday at 00:00.
+
+  Changes to past timestamps
+
+    Hong Kong's 1941-06-15 spring-forward transition was at 03:00, not
+    03:30.  Its 1945 transition from JST to HKT was on 11-18 at 02:00,
+    not 09-15 at 00:00.  In 1946 its spring-forward transition was on
+    04-21 at 00:00, not the previous day at 03:30.  From 1946 through
+    1952 its fall-back transitions occurred at 04:30, not at 03:30.
+    In 1947 its fall-back transition was on 11-30, not 12-30.
+    (Thanks to P Chan.)
+
+  Changes to past time zone abbreviations
+
+    Italy's 1866 transition to Rome Mean Time was on December 12, not
+    September 22.  This affects only the time zone abbreviation for
+    Europe/Rome between those dates.  (Thanks to Stephen Trainor and
+    Luigi Rosa.)
+
+  Changes affecting metadata only
+
+    Add info about the Crimea situation in zone1970.tab and zone.tab.
+    (Problem reported by Serhii Demediuk.)
+
+  Changes to code
+
+    zic's new -b option supports a way to control data bloat and to
+    test for year-2038 bugs in software that reads TZif files.
+    'zic -b fat' and 'zic -b slim' generate larger and smaller output;
+    for example, changing from fat to slim shrinks the Europe/London
+    file from 3648 to 1599 bytes, saving about 56%.  Fat and slim
+    files represent the same set of timestamps and use the same TZif
+    format as documented in tzfile(5) and in Internet RFC 8536.
+    Fat format attempts to work around bugs or incompatibilities in
+    older software, notably software that mishandles 64-bit TZif data
+    or uses obsolete TZ strings like "EET-2EEST" that lack DST rules.
+    Slim format is more efficient and does not work around 64-bit bugs
+    or obsolete TZ strings.  Currently zic defaults to fat format
+    unless you compile with -DZIC_BLOAT_DEFAULT=\"slim\"; this
+    out-of-the-box default is intended to change in future releases
+    as the buggy software often mishandles timestamps anyway.
+
+    zic no longer treats a set of rules ending in 2037 specially.
+    Previously, zic assumed that such a ruleset meant that future
+    timestamps could not be predicted, and therefore omitted a
+    POSIX-like TZ string in the TZif output.  The old behavior is no
+    longer needed for current tzdata, and caused problems with newlib
+    when used with older tzdata (reported by David Gauchard).
+
+    zic no longer generates some artifact transitions.  For example,
+    Europe/London no longer has a no-op transition in January 1996.
+
+  Changes to build procedure
+
+    tzdata.zi now assumes zic 2017c or later.  This shrinks tzdata.zi
+    by a percent or so.
+
+  Changes to documentation and commentary
+
+    The Makefile now documents the POSIXRULES macro as being obsolete,
+    and similarly, zic's -p POSIXRULES option is now documented as
+    being obsolete.  Although the POSIXRULES feature still exists and
+    works as before, in practice it is rarely used for its intended
+    purpose, and it does not work either in the default reference
+    implementation (for timestamps after 2037) or in common
+    implementations such as GNU/Linux (for contemporary timestamps).
+    Since POSIXRULES was designed primarily as a temporary transition
+    facility for System V platforms that died off decades ago, it is
+    being decommissioned rather than institutionalized.
+
+    New info on Bonin Islands and Marcus (thanks to Wakaba and Phake Nick).
