[0.10.0] - 2026-02-08

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 ReseedingRng (#1722)
• Removed unused feature "nightly" (#1732)
• Removed feature small_rng (#1732)

Closing: this PR comes from the /test/cargo-fuzz dependabot directory, which edits the root Cargo.toml without owning the root Cargo.lock, so it can never pass --locked. #38315 removes that directory. Bumps for these crates come from the / directory instead.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
