It seems the `leap-seconds.list` file hosted on the IANA server [1] is about to expire on 28 December 2025
The last IERS leap-seconds.list -> leap-seconds.3960835200 from 2025-07-07 expires at NTP timestamp 3991593600 on 2026-06-28 as usual. This agrees with the content in your dev repo posted by Tim on 2025-07-07, but differs from the outdated file from 2025-01-07 include in tzdata 2025b. The next leap-seconds.list -> leap-seconds.3976646400 will likely be issued 2026-01-06 expiring at NTP timestamp 4007404800 on 2026-12-28 as usual. This is based on the recent history of leap second files being issued about the 2nd Tuesday of January, depending on when the New Year and weekend falls, but may also depend on when USNO predictions are available.
Yes, it's time for a new release if only for that reason.
I was hoping the next release could cover the situation in Nunavik next year, but so far have not heard back from any of my attempts to contact Makivvik to get confirmation and/or details about the change and so I guess that will have to wait until a later TZDB release.
