build, ci: Adjust the default size of the precomputed table for signing #1564

hebasto · 2024-07-01T19:52:08Z

This PR implements the outcomes from today's IRC meeting:

The default size of the precomputed table for signing is now aligned with Bitcoin Core's default.
The default value in CI has been updated to reflect the new default.

The new default value of the precomputed table for signing is aligned with Bitcoin Core's default. See: bitcoin/bitcoin@a057869

I wonder how much this is a breaking change. 86 KB is larger than the old default (64KB), so this could be a problem for some users. But since we use static precomputation, this will be at most a build-time issue, so I don't think it deserves a 0.6.0 instead of 0.5.1 (assuming it makes it to the next release).

... I don't think it deserves a 0.6.0 instead of 0.5.1 (assuming it makes it to the next release).

I agree because there are no API changes.

I agree this is not a breaking change, though it does deserve a release note.
