Changelog

Sourced from rand's changelog.

[0.8.0] - 2020-12-18

Platform support

  • The minimum supported Rust version is now 1.36 (#1011)
  • getrandom updated to v0.2 (#1041)
  • Remove wasm-bindgen and stdweb feature flags. For details of WASM support, see the getrandom documentation. (#948)
  • ReadRng::next_u32 and next_u64 now use little-Endian conversion instead of native-Endian, affecting results on Big-Endian platforms (#1061)
  • The nightly feature no longer implies the simd_support feature (#1048)
  • Fix simd_support feature to work on current nightlies (#1056)

Rngs

  • ThreadRng is no longer Copy to enable safe usage within thread-local destructors (#1035)
  • gen_range(a, b) was replaced with gen_range(a..b). gen_range(a..=b) is also supported. Note that a and b can no longer be references or SIMD types. (#744, #1003)
  • Replace AsByteSliceMut with Fill and add support for [bool], [char], [f32], [f64] (#940)
  • Restrict rand::rngs::adapter to std (#1027; see also #928)
  • StdRng: add new std_rng feature flag (enabled by default, but might need to be used if disabling default crate features) (#948)
  • StdRng: Switch from ChaCha20 to ChaCha12 for better performance (#1028)
  • SmallRng: Replace PCG algorithm with xoshiro{128,256}++ (#1038)

Sequences

  • Add IteratorRandom::choose_stable as an alternative to choose which does not depend on size hints (#1057)
  • Improve accuracy and performance of IteratorRandom::choose (#1059)
  • Implement IntoIterator for IndexVec, replacing the into_iter method (#1007)
  • Add value stability tests for seq module (#933)

Misc

  • Support PartialEq and Eq for StdRng, SmallRng and StepRng (#979)
  • Added a serde1 feature and added Serialize/Deserialize to UniformInt and WeightedIndex (#974)
  • Drop some unsafe code (#962, #963, #1011)
  • Reduce packaged crate size (#983)
  • Migrate to GitHub Actions from Travis+AppVeyor (#1073)

Distributions

  • Alphanumeric samples bytes instead of chars (#935)
  • Uniform now supports char, enabling rng.gen_range('A'..='Z') (#1068)
  • Add UniformSampler::sample_single_inclusive (#1003)

Weighted sampling

  • Implement weighted sampling without replacement (#976, #1013)
  • rand::distributions::alias_method::WeightedIndex was moved to rand_distr::WeightedAliasIndex. The simpler alternative rand::distribution::WeightedIndex remains. (#945)
  • Improve treatment of rounding errors in WeightedIndex::update_weights (#956)
  • WeightedIndex: return error on NaN instead of panic (#1005)

Documentation

  • Document types supported by random (#994)
