From Paul Eggert's comments:

Changes affecting current time stamps

* Cuba observed DST starting Sunday.

* Resolute, Nunavut switched from Central to Eastern time last November.
  (Thanks to Chris Walton.)

Changes affecting near-future time stamps.

* Mongolia has abolished DST.  (Thanks to Ganbold Ts.)

* Turkey will use EU rules this year, changing at 01:00 UTC rather than
  01:00 standard time.  (Thanks to Steffen Thorsen.)

Changes affecting historical time stamps

* Indonesia couldn't have switched from JST on August 1, 1945.
  Use September 23 instead, as we have a source for that date.
  Similarly, change Jayapura's 1944-01-01 to 1944-09-01.
  (Thanks to JohnTWB.)

* Pangnirtung was founded in 1921, so it couldn't have been observing
  local time before that.  Similarly, Iqaluit was founded August 1942,
  Rankin Inlet 1957, Cambridge Bay 1920, Yellowknife 1935, Inuvik 1953.
  (Some of these dates are approximate; corrections welcome.)

Changes affecting comments only

* Ecuador observed DST in 1992, but we have no data.
  (Thanks to Ron Echeverri.)

* We have more formal announcements for Canada.
  (Thanks to Chris Walton.)

* Wisconsin's legal time now matches the US's.
  (Thanks to Douglas R. Bomberg.)
