+Palestine will spring forward on 2022-03-27, not 2022-03-26. (Thanks to Heba
+Hamad.)  Predict future transitions for first Sunday >= March 25.  Additionally,
+predict fallbacks to be the first Friday on or after October 23, not October's
+last Friday, to be more consistent with recent practice.  The first differing
+fallback prediction is on 2025-10-24, not 2025-10-31.
+
+## Changes to past timestamps
+
+From 1992 through spring 1996, Ukraine's DST transitions were at 02:00 standard
+time, not at 01:00 UTC.  (Thanks to Alois Treindl.)
+
+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
+
+Add several references for Chile's 1946/1947 transitions, some of which only
+affected portions of the country.
