The 2013h release of the tz code and data is available. It reflects
the following changes, which were either circulated on the tz mailing
list or are relatively minor technical or administrative changes:
Changes affecting current and future time stamps:
Libya has switched its time zone back to UTC+2 without DST,
instead of UTC+1 with DST. (Thanks to Even Scharning.)
Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
(Thanks to Gwillim Law.)
Changes affecting future time stamps:
Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5
on 2013-11-10. This affects America/Rio_Branco and America/Eirunepe.
(Thanks to Steffen Thorsen.)
Add entries for DST transitions in Morocco in the year 2038.
This avoids some year-2038 glitches introduced in 2013g.
(Thanks to Yoshito Umaoka for reporting the problem.)
Changes affecting API
The 'tzselect' command no longer requires the 'select' command,
and should now work with /bin/sh on more platforms. It also works
around a bug in BusyBox awk before version 1.21.0. (Thanks to
Patrick 'P. J.' McDermott.)
Changes affecting code
Fix localtime overflow bugs with 32-bit unsigned time_t.
zdump no longer assumes sscanf returns maximal values on overflow.
Changes affecting the build procedure
The builder can specify which programs to use, if any, instead of
'ar' and 'ranlib', and libtz.a is now built locally before being
installed. (Thanks to Michael Forney.)
A dependency typo in the 'zdump' rule has been fixed.
(Thanks to Andrew Paprocki.)
The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f'
work as specified by POSIX.2-1992 or later; this is portable nowadays.
'make clean' no longer removes 'leapseconds', since it's
host-independent and is part of the distribution.
The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed.
Changes affecting documentation and commentary
tz-link.htm now mentions TC TIMEZONE's draft timezone service protocol
(thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle).
Update URLs in tz-link page. Add URLs for Microsoft Windows, since
8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no
longer maintained) and for old advisories. SOFA now does C.

The 2013g release of the tz code and data is available. It reflects
the following changes, which were either circulated on the tz mailing
list or are relatively minor technical or administrative changes:
Changes affecting current and near-future time stamps
Morocco now observes DST from the last Sunday in March to the last
Sunday in October, not April to September respectively. (Thanks
to Steffen Thorsen.)
Changes affecting 'zic'
'zic' now runs on platforms that lack both hard links and symlinks.
(Thanks to Theo Veenker for reporting the problem, for MinGW.)
Also, fix some bugs on platforms that lack hard links but have symlinks.
'zic -v' again warns that Asia/Tehran has no POSIX environment variable
to predict the far future, fixing a bug introduced in 2013e.
Changes affecting the build procedure
The 'leapseconds' file is again put into the tzdata tarball.
Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to
Matt Burgess and Ian Abbott.) The timestamps of these and other
dependent files in tarballs are adjusted more consistently.
Changes affecting documentation and commentary
The README file is now part of the data tarball as well as the code.
It now states that files are public domain unless otherwise specified.
(Thanks to Andrew Main (Zefram) for asking for clarifications.)
Its details about the 1989 release moved to a place of honor near
the end of NEWS.
