Hi there, I've been doing maintenance catchup this afternoon but I think I won't be able to get to looking at this one today. In general I think we want to align the rand_core dependency of x25519-dalek with that of curve25519-dalek, which is stuck due to semver requirements on the major version. However, it turns out that we got the Serde implementation wrong (dalek-cryptography/curve25519-dalek#265 (comment)) so I would like to do a 2.0.0 release, and that may make it possible to update.

Any progress on this now that curve25519-dalek 2.0 is out?

[hdevalence]

Yup, this is unblocked now, I'm expecting that there will be a new x25519 version with new rand this week.
