        Description

        The 2016g 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 to future time stamps

             Turkey switched from EET/EEST (+02/+03) to permanent +03,
             effective 2016-09-07. (Thanks to Burak AYDIN.) Use "+03" rather
             than an invented abbreviation for the new time.

             New leap second 2016-12-31 23:59:60 UTC as per IERS Bulletin C 52.
             (Thanks to Tim Parenti.)

           Changes to past time stamps

             For America/Los_Angeles, spring-forward transition times have been
             corrected from 02:00 to 02:01 in 1948, and from 02:00 to 01:00 in
             1950-1966.

             For zones using Soviet time on 1919-07-01, transitions to UT-based
             time were at 00:00 UT, not at 02:00 local time. The affected
             zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and
             Europe/Ulyanovsk. (Thanks to Alexander Belopolsky.)

           Changes to past and future time zone abbreviations

             The Factory zone now uses the time zone abbreviation -00 instead
             of a long English-language string, as -00 is now the normal way to
             represent an undefined time zone.

             Several zones in Antarctica and the former Soviet Union, along
             with zones intended for ships at sea that cannot use POSIX TZ
             strings, now use numeric time zone abbreviations instead of
             invented or obsolete alphanumeric abbreviations. The affected
             zones are Antarctica/Casey, Antarctica/Davis,
             Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera,
             Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok,
             Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita,
             Asia/Dushanbe, Asia/Irkutsk, Asia/Kamchatka, Asia/Khandyga,
             Asia/Krasnoyarsk, Asia/Magadan, Asia/Omsk, Asia/Sakhalin,
             Asia/Samarkand, Asia/Srednekolymsk, Asia/Tashkent, Asia/Tbilisi,
             Asia/Ust-Nera, Asia/Vladivostok, Asia/Yakutsk, Asia/Yekaterinburg,
             Asia/Yerevan, Etc/GMT-14, Etc/GMT-13, Etc/GMT-12, Etc/GMT-11,
             Etc/GMT-10, Etc/GMT-9, Etc/GMT-8, Etc/GMT-7, Etc/GMT-6, Etc/GMT-5,
             Etc/GMT-4, Etc/GMT-3, Etc/GMT-2, Etc/GMT-1, Etc/GMT+1, Etc/GMT+2,
             Etc/GMT+3, Etc/GMT+4, Etc/GMT+5, Etc/GMT+6, Etc/GMT+7, Etc/GMT+8,
             Etc/GMT+9, Etc/GMT+10, Etc/GMT+11, Etc/GMT+12, Europe/Kaliningrad,
             Europe/Minsk, Europe/Samara, Europe/Volgograd, and
             Indian/Kerguelen. For Europe/Moscow the invented abbreviation MSM
             was replaced by +05, whereas MSK and MSD were kept as they are not
             our invention and are widely used.

           Changes to zone names

             Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link.
             (Thanks to David Massoud.)

           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.

            For now, JDK is not changing the invented abbreviations to the numeric one(like +03), for the already existing TimeZones. This new convention will be followed only for the newly added timezones.
