Release 0.10.0 · rust-random/rand

[0.10.0] - 2026-02-08

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)

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)
