|
||||
## [Unreleased]
|
||||
### Additions
|
||||
- impl PartialEq+Eq for StdRng, SmallRng, and StepRng (#975)
|
||||
- Added a `serde1` feature and added Serialize/Deserialize to `UniformInt` and `WeightedIndex` (#974)
|
||||
- Document types supported by `random` (#994)
|
||||
- Implement weighted sampling without replacement (#976, #1013)
|
||||
- Add `IteratorRandom::choose_stable` as an alternative to `choose` which does not depend on size hints (#1057)
|
||||
|
||||
### Changes
|
||||
- `getrandom` updated to v0.2 (#1041)
|
||||
- `ThreadRng` is no longer `Copy` to enable safe usage within thread-local destructors (see #968)
|
||||
- `gen_range(a, b)` was replaced with `gen_range(a..b)`, and `gen_range(a..=b)`
|
||||
is supported (#744, #1003). Note that `a` and `b` can no longer be references or SIMD types.
|
||||
- Replace `AsByteSliceMut` with `Fill` (#940)
|
||||
- Move alias method for `WeightedIndex` to `rand_distr` (#945)
|
||||
- `Alphanumeric` samples bytes instead of chars (#935)
|
||||
## [0.8.0] - 2020-12-18
|
||||
### Platform support
|
||||
- The minimum supported Rust version is now 1.36 (#1011)
|
||||
- Restrict `rand::rngs::adapter` to `std` (#1027)
|
||||
- Better NaN handling for `WeightedIndex` (#1005)
|
||||
- Implement `IntoIterator` for `IndexVec`, replacing the `into_iter` method (#1007)
|
||||
- Reduce packaged crate size (#983)
|
||||
- Drop some unsafe code (#962, #963, #1011)
|
||||
- Improve treatment of rounding errors in `WeightedIndex::update_weights` (#956)
|
||||
- `StdRng`: Switch from ChaCha20 to ChaCha12 for better performance (#1028)
|
||||
- `SmallRng`: Replace PCG algorithm with xoshiro{128,256}++ (#1038)
|
||||
- `getrandom` updated to v0.2 (#1041)
|
||||
- Remove `wasm-bindgen` and `stdweb` feature flags. For details of WASM support,
|
||||
see the [getrandom documentation](https://docs.rs/getrandom/latest). (#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)
|
||||
- `ReadRng::next_u32` and `next_u64` now use little-Endian conversion instead
|
||||
of native-Endian, affecting results on Big-Endian platforms (#1026)
|
||||
- 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)
|
||||
- Document notes on password generation (#995)
|
||||
- Note that `SmallRng` may not be the best choice for performance and in some
|
||||
other cases (#1038)
|
||||
- Use `doc(cfg)` to annotate feature-gated items (#1019)
|
||||
- Adjust README (#1065)
