From the release notes:
Changes affecting past time stamps
America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
not 1920-01-06. The old entry was based on a misinterpretation of Shanks.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Africa/Blantyre, Africa/Bujumbura,
Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.

Turks & Caicos is switching from US eastern time to UTC-4 year-round,

Changes affecting past time stamps
Time in Russia or the USSR before 1926 or so has been corrected by
a few seconds in the following zones: Asia/Irkutsk,
Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi,
Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For
Asia/Yekaterinburg the correction is a few minutes. (Thanks to
Vladimir Karpinsky.)
The Portuguese decree of 1911-05-26 took effect on 1912-01-01.
This affects 1911 time stamps in Africa/Bissau, Africa/Luanda,
Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912
GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32.
(Thanks to Stephen Colebourne for pointing to the decree.)
Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
A new file 'backzone' contains data which may appeal to
connoisseurs of old time stamps, although it is out of scope for
the tz database, is often poorly sourced, and contains some data
that is known to be incorrect. The new file is not recommended
for ordinary use and its entries are not installed by default.
(Thanks to Lester Caine for the high-quality Jersey, Guernsey, and
Isle of Man entries.)

Changes affecting future time stamps
Russia will subtract an hour from most of its time zones on
2014-10-26 at 02:00 local time. (Thanks to Alexander Krivenyshev.)
There are a few exceptions: Magadan Oblast (Asia/Magadan) and
Zabaykalsky Krai are subtracting two hours; conversely, Chukotka
Autonomous Okrug (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka),
Kemerovo Oblast (Asia/Novokuznetsk), and the Samara Oblast and the
Udmurt Republic (Europe/Samara) are not changing their clocks. The
changed zones are Europe/Kaliningrad, Europe/Moscow,
Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk,
Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk,
Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera;
Asia/Magadan will have two hours subtracted; and Asia/Novokuznetsk's
time zone abbreviation is affected, but not its UTC offset. Two
zones are added: Asia/Chita (split from Asia/Yakutsk, and also with
two hours subtracted) and Asia/Srednekolymsk (split from
Asia/Magadan, but with only one hour subtracted). (Thanks to Tim
Parenti for much of the above.)
Changes affecting past time stamps
China's five zones have been simplified to two, since the post-1970
differences in the other three seem to have been imaginary. The
zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been
removed; backwards-compatibility links still work, albeit with
different behaviors for time stamps before May 1980. Asia/Urumqi's
1980 transition to UTC+8 has been removed, so that it is now at
UTC+6 and not UTC+8. (Thanks to Luther Ma and to Alois Treindl;
Treindl sent helpful translations of two papers by Guo Qingsheng.)
Some zones have been turned into links, when they differed from
existing zones only for older UTC offsets where the data were likely
invented. These changes affect UTC offsets in pre-1970 time stamps
only. This is similar to the change in release 2013e, except this
time for western Africa. The affected zones are: Africa/Bamako,
Africa/Banjul, Africa/Conakry, Africa/Dakar, Africa/Freetown,
Africa/Lome, Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome,
and Atlantic/St_Helena. This also affects the
backwards-compatibility link Africa/Timbuktu. (Thanks to Alan
Barrett, Stephen Colebourne, Tim Parenti, and David Patte for
reporting problems in earlier versions of this change.)
Asia/Shanghai's pre-standard-time UT offset has been changed from
8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its
transition to standard time has been changed from 1928 to 1901.
Asia/Taipei switched to JWST on 1896-01-01, then to JST on
1937-10-01, then to CST on 1945-09-21 at 01:00, and did not observe
DST in 1945. In 1946 it observed DST from 05-15 through 09-30; in
1947 from 04-15 through 10-31; and in 1979 from 07-01 through 09-30.
(Thanks to Yu-Cheng Chuang.)
Asia/Riyadh's transition to standard time is now 1947-03-14, not
1950.
Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not
10-03 at 00:00. (Thanks to Konstantin Hyppönen.)
Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the
period from 1911 to 1950.
Pacific/Chatham has been changed to New Zealand standard time plus
45 minutes for the period before 1957, reflecting a 1956 remark in
the New Zealand parliament.
Europe/Budapest has several pre-1946 corrections: in 1918 the
transition out of DST was on 09-16, not 09-29; in 1919 it was on
11-24, not 09-15; in 1945 it was on 11-01, not 11-03; in 1941 the
transition to DST was 04-08 not 04-06 at 02:00; and there was no DST
in 1920.
Africa/Accra is now assumed to have observed DST from 1920 through
1935.
Time in Russia before 1927 or so has been corrected by a few seconds
in the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi,
Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg,
Europe/Helsinki, and Europe/Riga. Also, Moscow's location has been
changed to its Kilometer 0 point. (Thanks to Vladimir Karpinsky for
the Moscow changes.)

Changes affecting near-future time stamps
Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00.
(Thanks to Imed Chihi.) Guess that from 2015 on Egypt will temporarily
switch to standard time at 24:00 the last Thursday before Ramadan, and
back to DST at 00:00 the first Friday after Ramadan.
Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. (Thanks
to Milamber Space Network.) Guess that from 2015 on Morocco will
temporarily switch to standard time at 03:00 the last Saturday before
Ramadan, and back to DST at 02:00 the first Saturday after Ramadan.
Changes affecting past time stamps
The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of
"MSD" for Moscow's double daylight time in summer 1921. Also, a typo
"VLASST" has been repaired to be "VLAST" for Vladivostok summer time
in 1991. (Thanks to Hank W. for reporting the problems.)

Egypt observes DST starting 2014-05-15 at 24:00.

Details have not been announced, except that DST will not be
observed during Ramadan. Guess that DST will stop during the same
Ramadan dates as Morocco, and that Egypt's future spring and fall
transitions will be the same as 2010 when it last observed DST,
namely April's last Friday at 00:00 to September's last Thursday at
23:00 standard time. Also, guess that Ramadan transitions will be
at 00:00 standard time.

Changes affecting time stamps before 1970
Pacific/Johnston is now a link to Pacific/Honolulu. This corrects
some errors before 1947.
Some zones have been turned into links, when they differ from
existing zones only in older data that was likely invented or that
differs only in LMT or transition from LMT. These changes affect
only time stamps before 1943. The affected zones are:
Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
America/Grenada, America/Guadeloupe, America/Marigot,
America/Montserrat, America/St_Barthelemy, America/St_Kitts,
America/St_Lucia, America/St_Thomas, America/St_Vincent,
America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for
confirming that the old Europe/Vaduz zone was wrong and the new
link is better for WWII-era times.)
Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects
America/Cayman, America/Jamaica and America/Grand_Turk time stamps
from 1890 to 1912.
Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks

Change the date of the circa-1850 Zurich transition from 1849-09-12
to 1853-07-16, overriding Shanks with data from Messerli about
postal and telegraph time in Switzerland.
Data changes affecting behavior of tzselect and similar programs
Country code BQ is now called the more-common name "Caribbean Netherlands"
rather than the more-official "Bonaire, St Eustatius & Saba".
Remove from zone.tab the names America/Montreal, America/Shiprock,
and Antarctica/South_Pole, as they are equivalent to existing
same-country-code zones for post-1970 time stamps. The data for
these names are unchanged, so the names continue to work as before.
