Which model each app runs today, and when it last changed

Earliest possible date: a floor, not a deadline

One maker in this register describes its shutdown dates as the earliest possible dates on which a model might be retired. That makes each one a floor: access will not end before it and may end well after, with nothing published on the day it passes uneventfully. As of 2026-09-22.

The same row, read two ways. Recorded 2026-09-22.
Read as a deadlineRead as published
Access ends on this dayAccess ends no earlier than this day
Finish the migration by thenHave the migration ready, and hold it
If it moves, urgency was wastedIf it moves, that was expected
A passed date means it happenedA passed date may mean nothing at all

Inclusion rule. Read verbatim from the deprecations page of the one maker in this register that qualifies its dates this way. Order. Paired, with the common misreading first.

1Both misreadings cost something

Treating a floor as a deadline spends urgency that was not needed. Ignoring it because it is soft means discovering it was real. Neither reading is safe on its own, which is why the wording matters more than the number.

The workable position is to prepare for the date and expect to hold the migration. That costs storage and attention rather than a re-done season.

2Nothing marks the day a floor turns out to be soft

If a model keeps answering past its listed date, no correction is published and the row may simply remain. So a reader cannot tell whether a date slipped or whether their own check was wrong.

That makes the table honest and unusable as a record of what actually happened. This register keeps the wording verbatim rather than summarising it as a shutdown date.

3The opposite statement also exists here

One platform states its dates cannot be pushed back. Read together, the two sentences show that a published date can mean a fixed day or a lower bound, and that a reader has to check which.

The non-extendable term covers the other half. Length and direction are separate properties of any published date.

A definition rather than a dated entry: no line above is a vendor statement. Where this word turns up in a real notice, the wording and the date are on the reading on that wording. Nearby terms: Reading date, Reproducibility, Deprecated.
