Version 2026.2

Upstream version 2026b released 2026-04-23T06:06:43+00:00

Briefly:

British Columbia moved to permanent -07 on 2026-03-09. Some more overflow bugs
have been fixed in zic.

Changes to future timestamps

British Columbia’s 2026-03-08 spring forward was its last foreseeable clock
change, as it moved to permanent -07 thereafter. (Thanks to Arthur David Olson.)
Although the change to permanent -07 legally took place on 2026-03-09,
temporarily model the change to occur on 2026-11-01 at 02:00 instead. This
works around a limitation in CLDR v48.2 (2026-03-17). This temporary hack is
planned to be removed after CLDR is fixed.
