# Version 2025.3
Upstream version 2025c released 2025-12-10T22:42:37+00:00

## Briefly:

Several code changes for compatibility with FreeBSD.

## Changes to past timestamps

Baja California agreed with California’s DST rules in 1953 and in 1961 through
1975, instead of observing standard time all year. (Thanks to Alois Treindl.)

## Changes to commentary

The leapseconds file contains commentary about the IERS and NIST last-modified
and expiration timestamps for leap second data. (Thanks to Judah Levine.)

Commentary now also uses characters from the set –‘’“”•≤ as this can be useful
and should work with current applications.  This also affects data in
iso3166.tab and zone1970.tab, which now contain strings like “Côte d’Ivoire”
instead of “Côte d'Ivoire”.

# Version 2026.1
Upstream version 2026a released 2026-03-02T06:59:49+00:00

## Briefly:

Moldova has used EU transition times since 2022. The "right" TZif files are no
longer installed by default. -DTZ_RUNTIME_LEAPS=0 disables runtime support for
leap seconds. TZif files are no longer limited to 50 bytes of abbreviations. zic
is no longer limited to 50 leap seconds. Several integer overflow bugs have been
fixed.

## Changes to past and future timestamps

Since 2022 Moldova has observed EU transition times, that is, it has sprung
forward at 03:00, not 02:00, and has fallen back at 04:00, not 03:00.  (Thanks
to Heitor David Pinto.)

## Changes to data

Remove Europe/Chisinau from zonenow.tab, as it now agrees with Europe/Athens for
future timestamps.

# 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.
