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.

Changes to code
zic now always generates TZif files where time type 0 is used for
timestamps before the first transition. This simplifies the
reading of TZif files and should not affect behavior of existing
TZif readers because the same set of time types is used; only
their internal indexes may have changed. This affects only the
legacy zones EST5EDT, CST6CDT, MST7MDT, PST8PDT, CET, MET, and
EET, which previously used nonzero types for these timestamps.
Because of the type 0 change, zic no longer outputs a dummy
transition at time -2**59 (before the Big Bang), as clients should
no longer need this to handle historical timestamps correctly.
This reverts a change introduced in 2013d and shrinks most TZif
files by a few bytes.
zic now supports negative time-of-day in Rule and Leap lines, e.g.,
"Rule X min max - Apr lastSun -6:00 1:00 -" means the transition
occurs at 18:00 on the Saturday before the last Sunday in April.
This behavior was documented in 2018a but the code did not
entirely match the documentation.
localtime.c no longer requires at least one time type in TZif
files that lack transitions or have a POSIX-style TZ string. This
future-proofs the code against possible future extensions to the
format that would allow TZif files with POSIX-style TZ strings and
without transitions or time types.
A read-access subscript error in localtime.c has been fixed.
It could occur only in TZif files with timecnt == 0, something that
does not happen in practice now but could happen in future versions.
localtime.c no longer ignores TZif POSIX-style TZ strings that
specify only standard time. Instead, these TZ strings now
override the default time type for timestamps after the last
transition (or for all time stamps if there are no transitions),
just as DST strings specifying DST have always done.
leapseconds.awk now outputs "#updated" and "#expires" comments,
and supports leap seconds at the ends of months other than June
and December. (Inspired by suggestions from Chris Woodbury.)

Changes to build procedure
The command 'make tarballs' now also builds the tarball
tzdataVERSION-rearguard.tar.gz, which is like tzdataVERSION.tar.gz
except that it uses rearguard format intended for trailing-edge
data parsers.
Changes to data format and to code
The SAVE column of Rule and Zone lines can now have an 's' or 'd'
suffix, which specifies whether the adjusted time is standard time
or daylight saving time. If no suffix is given, daylight saving
time is used if and only if the SAVE column is nonzero; this is
the longstanding behavior. Although this new feature is not used
in tzdata, it could be used to specify the legal time in Namibia
1994-2017, as opposed to the popular time (see below).
Changes to past time stamps
From 1994 through 2017 Namibia observed DST in winter, not summer.
That is, it used negative DST, as Ireland still does. This change
does not affect UTC offsets; it affects only the tm_isdst flag and
the abbreviation used during summer, which is now CAT, not WAST.
Although (as noted by Michael Deckers) summer and winter time were
both simply called "standard time" in Namibian law, in common
practice winter time was considered to be DST (as noted by Stephen
Colebourne). The full effect of this change is only in vanguard
format; in rearguard and main format, the tm_isdst flag is still
zero in winter and nonzero in summer.
In 1946/7 Czechoslovakia also observed negative DST in winter.
The full effect of this change is only in vanguard format; in
rearguard and main formats, it is modeled as plain GMT without
daylight saving. Also, the dates of some 1944/5 DST transitions
in Czechoslovakia have been changed.

Backported to fixes from upstream too.
Changes to code
zic and the reference runtime now reject multiple leap seconds
within 28 days of each other, or leap seconds before the Epoch.
As a result, support for double leap seconds, which was
obsolescent and undocumented, has been removed. Double leap
seconds were an error in the C89 standard; they have never existed
in civil timekeeping. (Thanks to Robert Elz and Bradley White for
noticing glitches in the code that uncovered this problem.)
zic now warns about use of the obsolescent and undocumented -y
option, and about use of the obsolescent TYPE field of Rule lines.
zic now allows unambiguous abbreviations like "Sa" and "Su" for
weekdays; formerly it rejected them due to a bug. Conversely, zic
no longer considers non-prefixes to be abbreviations; for example,
it no longer accepts "lF" as an abbreviation for "lastFriday".
Also, zic warns about the undocumented usage with a "last-"
prefix, e.g., "last-Fri".
Similarly, zic now accepts the unambiguous abbreviation "L" for
"Link" in ordinary context and for "Leap" in leap-second context.
Conversely, zic no longer accepts non-prefixes such as "La" as
abbreviations for words like "Leap".
zic no longer accepts leap second lines in ordinary input, or
ordinary lines in leap second input. Formerly, zic sometimes
warned about this undocumented usage and handled it incorrectly.
The new macro HAVE_TZNAME governs whether the tzname external
variable is exported, instead of USG_COMPAT. USG_COMPAT now
governs only the external variables "timezone" and "daylight".
This change is needed because the three variables are not in the
same category: although POSIX requires tzname, it specifies the
other two variables as optional. Also, USG_COMPAT is now 1 or 0:
if not defined, the code attempts to guess it from other macros.
localtime.c and difftime.c no longer require stdio.h, and .c files
other than zic.c no longer require sys/wait.h.
zdump.c no longer assumes snprintf. (Reported by Jonathan Leffler.)
Calculation of time_t extrema works around a bug in GCC 4.8.4
(Reported by Stan Shebs and Joseph Myers.)
zic.c no longer mistranslates formats of line numbers in non-English
locales. (Problem reported by Benno Schulenberg.)
Several minor changes have been made to the code to make it a
bit easier to port to MS-Windows and Solaris. (Thanks to Kees
Dekker for reporting the problems.)
Changes to documentation and commentary
The two new files 'theory.html' and 'calendars' contain the
contents of the removed file 'Theory'. The goal is to document
tzdb theory more accessibly.
The zic man page now documents abbreviation rules.
tz-link.htm now covers how to apply tzdata changes to clients.
(Thanks to Jorge Fábregas for the AIX link.) It also mentions MySQL.
The leap-seconds.list URL has been updated to something that is
more reliable for tzdb. (Thanks to Tim Parenti and Brian Inglis.)

zdump -i now outputs non-hour numeric time zone abbreviations

zdump is now buildable again with -DUSE_LTZ=0.

zdump.c now always includes private.h, to avoid code duplication

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 affecting code
The time-related library functions now set errno on failure,
and some crashes in the new tzalloc-related library functions
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.
Changes affecting commentary

A lot of our recipes had short one-line DESCRIPTION values and no
SUMMARY value set. In this case it's much better to just set SUMMARY
since DESCRIPTION is defaulted from SUMMARY anyway and then the SUMMARY
is at least useful. I also took the opportunity to fix up a lot of the
new SUMMARY values, making them concisely explain the function of the
recipe / package where possible.
