DST law changes in Greenland and Mexico. Notably, a new timezone America/Ciudad_Juarez has been split off from America/Ojinaga. Historical corrections for northern Canada, Colombia, and Singapore.
DST law changes in Egypt, Greenland, Morocco, and Palestine. When observing Moscow time, Europe/Kirov and Europe/Volgograd now use the abbreviations MSK/MSD instead of numeric abbreviations, for consistency with other timezones observing Moscow time. Also, America/Yellowknife is no longer distinct from America/Edmonton; this affects some pre-1948 timestamps in that area.
DST law changes in Ittoqqortoormiit, Greenland (America/Scoresbysund), Kazakhstan (Asia/Almaty and Asia/Qostanay) and Palestine; as well as updates for the Antarctic stations Casey and Vostok. Historical corrections for Vietnam, Toronto, and Miquelon.
Historical corrections for Mexico, Mongolia, and Portugal. Notably, Asia/Choibalsan is now an alias for Asia/Ulaanbaatar rather than being a separate zone, mainly because the differences between those zones were found to be based on untrustworthy data.
DST law changes in Paraguay. Historical corrections for the Philippines. Backpatch-through: 13
DST law changes in Chile: there is a new time zone America/Coyhaique for Chile's Aysén Region, to account for it changing to UTC-03 year-round and thus diverging from America/Santiago. Historical corrections for Iran. Backpatch-through: 13

America/Ciudad_Juarez,America/Coyhaique), and historical corrections for multiple regions.Fixes #1670
