9.0.1 does not seem to work with bitcoin 0.30

[panicfarm]

I get this error with 0.30 (with 0.29 everything works)

Yes, there is no expectation that if you use a different major version of a dependency, that the crate will continue to work. This is why cargo will semi-automatically update minor versions, but force you to edit Cargo.toml to change major versions.

One important difference between cargo's "semver" and normal semver is that for 0.x.y, cargo treats x as the "major" and y as the "minor" rev, even though strictly speaking 0 should be the "major" and x the "minor".

We need 0.30 in the rest of our project, so we would like to use miniscript with the latest (0.30) rust-bitcoin major version. My understanding is that it's currently impossible? They are part of the same rust-bitcoin github, so it would be nice if all latest versions where sync'd.

Yes, this library would need to be updated to work with 0.30. The current state of that work is at #537. You could try using the branch from that PR.

[sanket1729]

You can try with #537 branch while it is being reviewed.

Fixed by #537
