[Unreleased]

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)

Removals

  • Removed ReseedingRng (#1722)

[0.9.2] - 2025-07-20

Deprecated

  • Deprecate rand::rngs::mock module and StepRng generator (#1634)

Additions

  • Enable WeightedIndex<usize> (de)serialization (#1646)

[0.9.1] - 2025-04-17

Security and unsafe

  • Revise "not a crypto library" policy again (#1565)
  • Remove zerocopy dependency from rand (#1579)

either keep stable rand 0.9 by pinning rand_chacha back to 0.9.x, or move to rand 0.10.0-rc.x plus rand_distr 0.6.0-rc.x to keep rand_chacha 0.10.0

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.
