Import tzdata2022agtz not from ftp://ftp.iana.org/tz/releases/tzdata2022agtz.tar.gz (2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)
Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Release 2020e - 2020-12-22 15:14:34 -0800
Volgograd switched to Moscow time on 2020-12-27 at 02:00.
Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include changes to: Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine, Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu
Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

Summary of changes in tzdata2015c (2015-04-11 08:55:55 -0700): * Egypt's spring-forward transition is at 24:00 on April's last Thursday, not 00:00 on April's last Friday. This affects 2015, 2026, 2037, 2043, etc. * Changes to pre-1991 Chile-related time stamps in America/Santiago, Antarctica/Palmer, and Pacific/Easter. * The America/Montreal zone has been turned into a link, as it differed from an existing zone only for pre-1970 time stamps.

Asia/Ho_Chi_Minh has been added to zone1970.tab, to give tzselect users in Vietnam two choices, since north and south Vietnam disagreed after our 1970 cutoff. * Asia/Phnom_Penh and Asia/Vientiane have been turned into links, as they differed from existing zones only for older (pre-1970) time stamps. * Changes affecting commentary.

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * 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. * Changes affecting documentation and commentary.

Import tzdata2022agtz not from ftp://ftp.iana.org/tz/releases/tzdata2022agtz.tar.gz (2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)
Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include changes to: Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine, Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu
Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * Some more zones have been turned into links, when they differed from existing zones only for older time stamps.

Summary of changes in tzdata2022g (2022-11-29 08:58:31 -0800): * In the Mexican state of Chihuahua, the border strip near the US will change to agree with nearby US locations on 2022-11-30. * Much of Greenland, represented by America/Nuuk, stops observing winter time after March 2023, so its daylight saving time becomes standard time. * Changes for pre-1996 northern Canada (thanks to Chris Walton): * Merge America/Iqaluit and America/Pangnirtung into the former, with a backward compatibility link for the latter name. * Cambridge Bay, Inuvik, Iqaluit, Rankin Inlet, Resolute and Yellowknife did not observe DST in 1965, and did observe DST from 1972 through 1979. * Whitehorse moved from -09 to -08 on 1966-02-27, not 1967-05-28. * Colombia's 1993 fallback was 02-06 24:00, not 04-04 00:00. * Singapore's 1981-12-31 change was at 16:00 UTC (23:30 local time), not 24:00 local time.

Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

Release 20198 - 2019-03-25 22:01:33 -0700
Briefly: Palestine summer time starts on 2019-03-30 instead of 2019-03-23. Metlakatla switched back to rejoin Alaska Time on 2019-01-20 at 02:00.
Israel observed summer time in 1980 (08-02/09-13) and 1984 (05-05/08-25).
Etc/UCT is now a backward-compatibility link to Etc/UTC, instead of being a separate zone that generates the abbreviation "UCT".

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * Some more zones have been turned into links, when they differed from existing zones only for older time stamps.

Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Release 2020f - 2020-12-29 00:17:46 -0800
No changes to tzdata, just to a part of the build procedure not used on NetBSD
Release 2020e - 2020-12-22 15:14:34 -0800
Volgograd switched to Moscow time on 2020-12-27 at 02:00.
Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include changes to: Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine, Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu
Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

Summary of changes in tzdata2014h (2014-09-25 18:59:03 -0700): * 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. * 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. * Changes affecting documentation and commentary.

Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700): * Turks & Caicos is switching from US eastern time to UTC-4 year-round, modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00. * Time in Russia or the USSR before 1926 or so has been corrected by a few seconds for several zones, and a few minutes for Asia/Yekaterinburg. * The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not on the date of the decree. This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * 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. * Changes affecting documentation and commentary.

Import tzdata2022agtz not from ftp://ftp.iana.org/tz/releases/tzdata2022agtz.tar.gz (2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)
Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Release 2020e - 2020-12-22 15:14:34 -0800
Volgograd switched to Moscow time on 2020-12-27 at 02:00.
Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include changes to: Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine, Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu
Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * Some more zones have been turned into links, when they differed from existing zones only for older time stamps.

Import tzdata2022agtz not from ftp://ftp.iana.org/tz/releases/tzdata2022agtz.tar.gz (2022a comes from ftp://ftp.iana.org/tz/releases/tzdata2022a.tar.gz)
Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Release 2020e - 2020-12-22 15:14:34 -0800
Volgograd switched to Moscow time on 2020-12-27 at 02:00.

Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

Asia/Ho_Chi_Minh has been added to zone1970.tab, to give tzselect users in Vietnam two choices, since north and south Vietnam disagreed after our 1970 cutoff. * Asia/Phnom_Penh and Asia/Vientiane have been turned into links, as they differed from existing zones only for older (pre-1970) time stamps. * Changes affecting commentary.

Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700): * Turks & Caicos is switching from US eastern time to UTC-4 year-round, modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00. * Time in Russia or the USSR before 1926 or so has been corrected by a few seconds for several zones, and a few minutes for Asia/Yekaterinburg. * The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not on the date of the decree. This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * 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. * Changes affecting documentation and commentary.

Note that 2022agtz is mechanically derived from 2022a by moving back zone data from the "backzone" file that had been removed as "redundant" (because differences to some other zone are all prior to 1970) so that this pre 1970 data is restored. It isn't necessarily correct in all cases, but it is usually better than using some other zone's data which is just as likely to be incorrect for where it applies, and more so elsewhere.
Summary of changes in tzdata2022a (2022-03-15 23:02:01 -0700): * Palestine will spring forward on 2022-03-27, not 2022-03-26. * From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard time, not at 01:00 UTC. * Chile's Santiago Mean Time and its LMT precursor have been adjusted eastward by 1 second to align with past and present law. * Changes to commentary.

Volgograd switched to Moscow time on 2020-12-27 at 02:00.
Correct many pre-1986 transitions, fixing entries originally derived from Shanks. The fixes include changes to: Australia, Bahamas, Bermuda, Belize, Ghana, Israel and Palestine, Kenya and adjacent, Nigeria and adjacent, Seychelles, Vanuatu
Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * Some more zones have been turned into links, when they differed from existing zones only for older time stamps.

Australia/Currie has been moved to the 'backward' file and its corrected data moved to the 'backzone' file.
To better match legislation in Turks and Caicos, the 2015 shift to year-round observance of -04 is now modeled as AST throughout before returning to Eastern Time with US DST in 2018, rather than as maintaining EDT until 2015-11-01.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * Some more zones have been turned into links, when they differed from existing zones only for older time stamps.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

2018a and 2018b were (kind of) released, but never announced. Some "issues" were found with them that caused the relatively quick updates...
The updates are from the previous version (2017c) to the current one (2018c) - that 2018a & 2018b intervened is best forgotten... (changes in 2018a that were corrected (2018b) or reverted (2018c) are not mentioned).
Briefly:
Sao Tome and Principe (An island nation off west coast of Equatorial Africa) switched from +00 to +01.
Brazil's DST will now start on November's first Sunday.
Use Debian-style installation locations, instead of 4.3BSD-style. (this does not affect NetBSD, we do not use the tzdata Makefile)
Changes to past and future time stamps
Sao Tome and Principe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
Changes to future time stamps
Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.)
The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid before 1979, to agree with tables compiled by Pere Planesas of the National Astronomical Observatory of Spain. As a side effect, this changes some time stamps for Africa/Ceuta before 1929, which are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the abbreviation "AST", the abbreviation commonly used at the time (Atlantic Standard Time had not been standardized yet). Use "AWT" and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau before 1999 and Taiwan before 1938, and use "JST" instead of the invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward', since Johnston is now uninhabited.

Guess that future years will use a similar pattern. * A new Zone Pacific/Bougainville, for the part of Papua New Guinea that plans to switch from UTC+10 to UTC+11 on 2014-12-28 at 02:00. * Since Belarus is not changing its clocks even though Moscow is, the time zone abbreviation in Europe/Minsk is changing from FET to its more-traditional value MSK on 2014-10-26 at 01:00. * The new abbreviation IDT stands for the pre-1976 use of UT+8 in Indochina, to distinguish it better from ICT (UT+7). * Many time stamps have been corrected for Asia/Ho_Chi_Minh before 1976. Asia/Ho_Chi_Minh has been added to zone1970.tab, since north and south Vietnam disagreed after our 1970 cutoff. * Asia/Phnom_Penh and Asia/Vientiane have been turned into links, as they differed from existing zones only for pre-1970 time stamps. * Changes affecting commentary.

Summary of changes in tzdata2014h (2014-09-25 18:59:03 -0700): * 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. * 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. * Changes affecting documentation and commentary.

Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700): * Turks & Caicos is switching from US eastern time to UTC-4 year-round, modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00. * Time in Russia or the USSR before 1926 or so has been corrected by a few seconds for several zones, and a few minutes for Asia/Yekaterinburg. * The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not on the date of the decree. This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. * 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. * 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. * Changes affecting documentation and commentary.
