Release Notes

rust-lang-nursery/rand (rand_core)

v0.10.1

Compare Source

This release includes a fix for a soundness bug; see #​1763.

Changes

• Document panic behavior of make_rng and add #[track_caller] (#​1761)
• Deprecate feature log (#​1763)

v0.10.0

Compare Source

Changes

• The dependency on rand_chacha has been replaced with a dependency on chacha20. This changes the implementation behind StdRng, but the output remains the same. There may be some API breakage when using the ChaCha-types directly as these are now the ones in chacha20 instead of rand_chacha (#​1642).
• Rename fns IndexedRandom::choose_multiple -> sample, choose_multiple_array -> sample_array, choose_multiple_weighted -> sample_weighted, struct SliceChooseIter -> IndexedSamples and fns IteratorRandom::choose_multiple -> sample, choose_multiple_fill -> sample_fill (#​1632)
• Use Edition 2024 and MSRV 1.85 (#​1653)
• Let Fill be implemented for element types, not sliceable types (#​1652)
• Fix OsError::raw_os_error on UEFI targets by returning Option<usize> (#​1665)
• Replace fn TryRngCore::read_adapter(..) -> RngReadAdapter with simpler struct RngReader (#​1669)
• Remove fns SeedableRng::from_os_rng, try_from_os_rng (#​1674)
• Remove Clone support for StdRng, ReseedingRng (#​1677)
• Use postcard instead of bincode to test the serde feature (#​1693)
• Avoid excessive allocation in IteratorRandom::sample when amount is much larger than iterator size (#​1695)
• Rename os_rng -> sys_rng, OsRng -> SysRng, OsError -> SysError (#​1697)
• Rename Rng -> RngExt as upstream rand_core has renamed RngCore -> Rng (#​1717)

Additions

• Add fns IndexedRandom::choose_iter, choose_weighted_iter (#​1632)
• Pub export Xoshiro128PlusPlus, Xoshiro256PlusPlus prngs (#​1649)
• Pub export ChaCha8Rng, ChaCha12Rng, ChaCha20Rng behind chacha feature (#​1659)
• Fn rand::make_rng() -> R where R: SeedableRng (#​1734)

Removals

• Removed unused feature "nightly" (#​1732)
• Removed feature small_rng (#​1732)

🔴 Rust SDK no longer builds after the random-number library upgrade

The random-number library is upgraded to a version whose randomness source no longer exists (rand_core = "0.10" at sdk/rust/Cargo.toml:18) while the signing code still asks for that removed source, so the Rust SDK fails to build at all.
Impact: Anyone depending on or publishing the Rust client gets a broken package — no requests can be signed or sent.

Removed OsRng/RngCore items in rand_core 0.10 vs. the SDK's usage

sdk/rust/src/lib.rs:22-23 does use rand_core::{OsRng, RngCore}; OsRng.fill_bytes(&mut nonce_bytes); to build the CDP-JWT nonce. rand_core 0.10 removed OsRng (and the os_rng/getrandom support) entirely and renamed RngCore to Rng, so both imports resolve to nothing. Additionally, p256 = "0.13" (sdk/rust/Cargo.toml:17) is built against the rand_core 0.6 trait family, so even after fixing the import the two crates would not share RNG traits. Either keep rand_core = "0.6" (matching the accompanying comment and p256 0.13), or migrate the nonce generation to getrandom/rand and upgrade p256 accordingly.

🟡 Dependency change to the published client is not recorded in the changelog

A user-facing dependency requirement of the published Rust client is changed (rand_core = "0.10" at sdk/rust/Cargo.toml:18) without adding an entry under the Unreleased section of the changelog, which the repository contract requires.
Impact: Consumers of the SDK get an undocumented dependency change.

Repository rule

AGENTS.md states: "Conventional Commit titles; update CHANGELOG.md (Unreleased) for user-facing changes." The ## [Unreleased] section of CHANGELOG.md is empty in this PR.

🔍 No lockfile or CI build for the Rust SDK to catch dependency drift

There is no Cargo.lock committed under sdk/rust/, and the change here is dependency-only, so nothing in the repo pins or verifies the resolved rand_core version. If CI does not run cargo build for sdk/rust, a bad requirement would only surface at publish time. Worth confirming a Rust build gate exists.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This one-line dependency update affects the published Rust SDK's existing CDP-JWT signing path, while the unchanged code appears incompatible with the upgraded rand_core API and no Rust build gate verifies the result. The change also raises consumer compatibility and changelog concerns in a file owned by the streaming team.

Not approved because:

• Credit balance exhausted. Approvability relies on correctness review in order to determine eligibility

🔍 No CHANGELOG entry for the dependency change of a published crate

AGENTS.md asks for a CHANGELOG.md Unreleased entry for user-facing changes. A dependency major bump in a published crate (wave-dispatch) changes the resolved dependency graph for consumers, so it is arguably user-facing; the Unreleased section is currently empty. Worth confirming the repo's convention for dependency-only PRs (e.g. Renovate-generated) before requiring an entry.

🔍 Stale inline version comment and MSRV/edition implications of the bump

The trailing comment still reads # 0.6.2 — nonce randomness for CDP-JWT, which refers to the SDK feature version rather than the crate version, so it is not inconsistent by itself. More relevant: rand_core 0.10 requires edition 2024 and MSRV 1.85, while sdk/rust/Cargo.toml:4 declares edition = "2021". Consuming a 2024-edition dependency is allowed, but the effective MSRV of the published wave-dispatch crate silently rises to 1.85; if the project documents or CI-tests an older toolchain, that needs updating alongside this bump.
