Briefly: Haiti has resumed DST.
Changes to past and future time stamps
Haiti resumed observance of DST in 2017. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430"
is one byte over the POSIX limit. (Problem reported by Derick Rethans.)

Changes to code
zic no longer mishandles some transitions in January 2038 when it
attempts to work around Qt bug 53071. This fixes a bug affecting
Pacific/Tongatapu that was introduced in zic 2016e. localtime.c
now contains a workaround, useful when loading a file generated by
a buggy zic. (Problem and localtime.c fix reported by Bradley
White.)
zdump -i now outputs non-hour numeric time zone abbreviations
without a colon, e.g., "+0530" rather than "+05:30". This agrees
with zic %z and with common practice, and simplifies auditing of
zdump output.
zdump is now buildable again with -DUSE_LTZ=0.
(Problem reported by Joseph Myers.)
zdump.c now always includes private.h, to avoid code duplication
with private.h. (Problem reported by Kees Dekker.)
localtime.c no longer mishandles early or late timestamps
when TZ is set to a POSIX-style string that specifies DST.
(Problem reported by Kees Dekker.)
date and strftime now cause %z to generate "-0000" instead of
"+0000" when the UT offset is zero and the time zone abbreviation
begins with "-".
Changes to documentation and commentary
The 'Theory' file now better documents choice of historical time
zone abbreviations. (Problems reported by Michael Deckers.)
tz-link.htm now covers leap smearing, which is popular in clouds.

Also, when the destination already contains symbolic links, zic

does not follow symbolic links.
Changes to documentation and commentary

LICENSE file checksum changed do to a verbage change.
Changes to code
zic no longer generates binary files containing POSIX TZ-like
strings that disagree with the local time type after the last
explicit transition in the data. This fixes a bug with
Africa/Casablanca and Africa/El_Aaiun in some year-2037 time
stamps on the reference platform. (Thanks to Alexander Belopolsky
for reporting the bug and suggesting a way forward.)
If the installed localtime and/or posixrules files are symbolic
links, zic now keeps them symbolic links when updating them, for
compatibility with platforms like OpenSUSE where other programs
configure these files as symlinks.
zic now avoids hard linking to symbolic links, avoids some
unnecessary mkdir and stat system calls, and uses shorter file
names internally.
zdump has a new -i option to generate transitions in a
more-compact but still human-readable format. This option is
experimental, and the output format may change in future versions.
(Thanks to Jon Skeet for suggesting that an option was needed,
and thanks to Tim Parenti and Chris Rovick for further comments.)
Changes to build procedure
An experimental distribution format is available, in addition
to the traditional format which will continue to be distributed.
The new format is a tarball tzdb-VERSION.tar.lz with signature
file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory
tzdb-VERSION containing the code and data of the traditional
two-tarball format, along with extra data that may be useful.
(Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others
for comments about the experimental format.)
The release version number is now more accurate in the usual case
where releases are built from a Git repository. For example, if
23 commits and some working-file changes have been made since
release 2016g, the version number is now something like
'2016g-23-g50556e3-dirty' instead of the misleading '2016g'.
Official releases uses the same version number format as before,
e.g., '2016g'. To support the more-accurate version number, its
specification has moved from a line in the Makefile to a new
source file 'version'.
The experimental distribution contains a file to2050.tzs that
contains what should be the output of 'zdump -i -c 2050' on
primary zones. If this file is available, 'make check' now checks
that zdump generates this output.
'make check_web' now works on Fedora-like distributions.
Changes to documentation and commentary
tzfile.5 now documents the new restriction on POSIX TZ-like
strings that is now implemented by zic.
Comments now cite URLs for some 1917-1921 Russian DST decrees.
(Thanks to Alexander Belopolsky.)
tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J
(thanks to Meno Hochschild) and ThreeTen-Extra, and its
description of Java 8 has been brought up to date (thanks to
Stephen Colebourne). Its description of local time on Mars has
been updated to match current practice, and URLs have been updated
and some obsolete ones removed.

The time-related library functions now set errno on failure,

have been fixed. (Thanks to Christos Zoulas for reporting
most of these problems and for suggesting fixes.)
If USG_COMPAT is defined and the requested time stamp is
standard time, the tz library's localtime and mktime functions
now set the extern variable timezone to a value appropriate
for that time stamp; and similarly for ALTZONE, daylight
saving time, and the altzone variable. This change is a
companion to the tzname change in 2014h, and is designed to
make timezone and altzone more compatible with tzname.
The tz library's functions now set errno to EOVERFLOW if they
fail because the result cannot be represented. ctime and
ctime_r now return NULL and set errno when a time stamp is out
of range, rather than having undefined behavior.
Some bugs associated with the new 2014g functions have been
fixed. This includes a bug that largely incapacitated the new
functions time2posix_z and posix2time_z. (Thanks to Christos
Zoulas.) It also includes some uses of uninitialized
variables after tzalloc. The new code uses the standard type
'ssize_t', which the Makefile now gives porting advice about.
