How were these files chosen for update? I see that many other headers are missing the -present part:

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/src/node/abort.cpp#L1

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/src/common/args.h#L1

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/src/bech32.h#L2

and many others have a older end year:

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/src/bech32.cpp#L2

or don’t even contain a year:

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/ci/lint_imagefile#L1

or have the SPDX header only:

https://github.com/bitcoin/bitcoin/blob/01b9a6183eb58dffac00f053e2742d924c84c721/src/test/fuzz/FuzzedDataProvider.h#L5

or don’t have any copyright header:

Only found these in Python dependencies, so: 👍

Unrelated: we could update the script to change the end year to present instead

fanquake commented at 6:44 pm on February 20, 2025:

I have changes for this locally, but the value is low, and ideally all of this code will soon be removed.
l0rinc approved
l0rinc commented at 12:48 pm on February 18, 2025: contributor

While I admit having stronger feelings against the copyright headers than I should (noise + bikeshedding + revoking right to copy in general), I do value consistency, so it’s a 👍 from me - I wish we could unify more to get rid of this extra source of disagreement, but this PR makes it a bit better, so:

I see you’ve removed the 2024-present from the latest push - is that a general direction from now on?

Not entirely clear to me which MIT license URL we’re using now, and when we’re using year ranges and when single years.
