## [0.5.0-alpha.1] - 2024-03-18
- Target `rand` version `0.9.0-alpha.1`
2024-02-18 17:02:05 +00:00
## [0.5.0-alpha.0] - 2024-02-18
This is a pre-release. To depend on this version, use `rand_distr = "=0.5.0-alpha.0"` to prevent automatic updates (which can be expected to include breaking changes).
### Additions
- Make distributions comparable with `PartialEq` (#1218 )
- Add `WeightedIndexTree` (#1372 )
### Changes
- Target `rand` version `0.9.0-alpha.0`
2021-09-15 19:12:24 +02:00
- Remove unused fields from `Gamma` , `NormalInverseGaussian` and `Zipf` distributions (#1184 )
This breaks serialization compatibility with older versions.
2023-03-18 05:21:59 -04:00
- `Dirichlet` now uses `const` generics, which means that its size is required at compile time (#1292 )
- The `Dirichlet::new_with_size` constructor was removed (#1292 )
2021-09-15 19:12:24 +02:00
2024-02-18 17:02:05 +00:00
### Fixes
- Fix Knuth's method so `Poisson` doesn't return -1.0 for small lambda (#1284 )
- Fix `Poisson` distribution instantiation so it return an error if lambda is infinite (#1291 )
- Fix Dirichlet sample for small alpha values to avoid NaN samples (#1209 )
- Fix infinite loop in `Binomial` distribution (#1325 )
2021-12-28 16:52:13 +03:00
