There isn't really much downside to running the uploads with verbose
mode on when nothing goes wrong (who is even going to look at the logs?)
and when something goes wrong it's very nice to have, so we'll just
leave it on always.

Subject: [PATCH 13/26] Verify signatures of tarballs (#108)

If they stop signing the tzdata releases in the future, or if this turns out to just create a bunch of pointless noise, we can just disable this check. It's a nice-to-have thing as long as the signing works well, but my impression is that the modern view of GPG-signed releases is that it doesn't add much to the security model, and plus I don't see it as especially risky if we get malicious data anyway.

Subject: [PATCH 19/26] Update tzdata to version '2025c'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# 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”.

Subject: [PATCH 26/26] Update tzdata to version '2026a' (#123)

# 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.
