Release 0.14.0 by str4d · Pull Request #130 · zkcrypto/ff

str4d · 2025-03-09T03:35:50Z

This is a feature branch; PR is open to track the overall 0.14.0 changes.

Raise MSRV to 1.63

Bump rand to 0.9

Relax `Sized` requirements on the rng

str4d · 2025-03-09T05:41:08Z


    /// Returns an element chosen uniformly at random using a user-provided RNG.
-    fn random(rng: impl RngCore) -> Self;
+    fn random<R: RngCore + ?Sized>(rng: &mut R) -> Self;


This change is blocked on being included in a zkcrypto RFC.

str4d · 2025-03-09T05:43:40Z

CI is failing because changes in main currently conflict with changes here. I will fix this by merging main into this PR after #131 is merged.

baloo · 2025-03-09T06:00:53Z

I'm not very familiar with the zkcrypto processes, any chance you could tag and publish a pre-release for 0.14.0? (with #127 preferably).

str4d · 2025-03-09T07:04:37Z

That's my plan. We do not normally do pre-releases because they are hard to use correctly in general, but given the need to coordinate with RustCrypto I'll be doing so in this instance.

And as noted elsewhere, the trait changes in any pre-release builds will not be included in the final release unless they are also in a merged zkcrypto RFC. The pre-release builds we create in this instance should be used for RFC consensus building.

adds a Field::try_from_rng method

see zkcrypto/ff#130

Preview 0.14.0-pre.0

str4d · 2025-11-22T00:56:35Z

RustCrypto have decided to skip rand_core 0.9 entirely, and moved to 0.10.0-rc* in the last few weeks. There's very little motivation for me now in releasing ff 0.14 with rand_core 0.9, because it would be nigh-unusable in concrete downstreams like bls12_381 and pasta_curves which depend on various RustCrypto trait crates. So I will review #147 (and the equivalent PRs on group etc.) for an ff 0.14.0-pre.1.

This has two main implications:

ff 0.14 will have an MSRV bump to whatever rand_core 0.10 uses (currently 1.85, which seems reasonable as that's the Rust 2024 edition boundary).
ff 0.14 will be blocked until rand_core 0.10 releases, which currently has no date. (Thus far we've been blocked on a zkcrypto RFC being written but also waiting for RustCrypto to get close to needing a published ff 0.14 to ensure we're compatible; useful in this particular instance!)

Release notes: https://github.com/rust-random/rand_core/releases/tag/v0.10.0

Bump `rand_core` to v0.10; MSRV 1.85

Followup to #149, since the name has been changed in zkcrypto/rfcs#1

Rename `Field::try_from_rng` => `try_random`

left some minor nits, sorry to be pedantic.

nit; this comment could be clearer, feels circular.

If this is going to be a final v0.14.0 release of ff, can you take a look at #155 first?

If this is going to be a final v0.14.0 release of ff, can you take a look at #155 first?

responded to the issue, and filed #156 and zkcrypto/group#81.

this seems to require an RFC (like #130 (comment)) which carries a 10-day FCP, so proposing this be included in a next minor point release and not block this release on that change. cc @ebfull @str4d @tarcieri.

str4d · 2026-05-28T20:46:49Z

Yes, it would require an RFC. And it also requires some more significant design work per #155 (comment).
