+# Version 2025.1
+Upstream version 2025a released 2025-01-15T18:47:24+00:00
+
+## Briefly:
+
+Paraguay adopts permanent -03 starting spring 2024. Improve pre-1991 data for
+the Philippines. Etc/Unknown is now reserved.
+
+## Changes to future timestamps
+
+Paraguay will stop changing its clocks after the spring-forward transition on
+2024-10-06, so it is now permanently at -03. (Thanks to Heitor David Pinto and
+Even Scharning.) This affects timestamps starting 2025-03-22, as well as the
+obsolescent tm_isdst flags starting 2024-10-15.
+
+## Changes to past timestamps
+
+Correct timestamps for the Philippines before 1900, and from 1937 through 1990.
+(Thanks to P Chan for the heads-up and citations.) This includes adjusting local
+mean time before 1899; fixing transitions in September 1899, January 1937, and
+June 1954; adding transitions in December 1941, November 1945, March and
+September 1977, and May and July 1990; and removing incorrect transitions in
+March and September 1978.
+
+## Changes to data
+
+Add zone1970.tab lines for the Concordia and Eyre Bird Observatory research
+stations.  (Thanks to Derick Rethans and Jule Dabars.)
+
+## Changes to documentation
+
+The name Etc/Unknown is now reserved: it will not be used by TZDB. This is for
+compatibility with CLDR, which uses the string "Etc/Unknown" for an unknown or
+invalid timezone.  (Thanks to Justin Grant, Mark Davis, and Guy Harris.)
+
+Cite Internet RFC 9636, which obsoletes RFC 8536 for TZif format.
