Sourced from snow's releases.

v0.10.0

Quick Summary

snow is now no_std-friendly, with only one required dependency (subtle) now if you bring your own cryptographic provider, thank you @​complexspaces!

This release also sees some breaking API changes in the builder to further prevent misuse/abuse - more builder functions now return Result<Self, Error> instead of Self.

The P-256 curve is now also available as a non-default feature for those of you needing more curves in your life.

Finally, this release transitioned the snow codebase to Rust 2024 and has a new MSRV of 1.85.

Migrating from 0.9

The main change you'll likely notice is the need to add expect(...) or ? to a few builder functions that have been updated to further limit the chance of misuse.

Here are the semver-breaking changes:

• Builder function fallibility: more functions in the builder now return a Result to more explicitly prohibit calling the same setter twice.
• DHChoice::Ed448 has been renamed to DHChoice::Curve448
• Multiple new error enum variants have been added.
