v0.3.26 has a subtle breaking change

[assafmo]

Hi guys, please see this commit message on our project's repo: scrtlabs/SecretNetwork@a8f623f

Pin xargo to v0.3.25

As xargo v0.3.26 contains breaking changes, specifically this: v0.3.25...v0.3.26diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5L147-R148 which caused an error[E0463]: can't find crate for "core" error when building

This is because of the change to the search path of sysroot. You might want to also tag v0.3.26 as v0.4.0.

Your link is broken, I assume you mean this one. (EDIT: ah fun, github breaks this link)

That diff comes from #338. That's just a doc change though, it does not change behavior. This folder it mentions (src in the Rust repository) has been wrong for years (ever since the Rust standard library was moved to library), and I finally fixed the docs.

Whatever problem you are seeing is definitely not caused by #338.
