Full Changelog: rust-random/rand_distr@0.5.0...0.5.1

0.5.0

Dependencies and features

• Bump the MSRV to 1.61.0 (#1207, #1246, #1269, #1341, #1416); note that 1.60.0 may work for dependents when using --ignore-rust-version
• Update to rand v0.9.0 (#1558)
• Rename feature serde1 to serde (#1477)

API changes

• Make distributions comparable with PartialEq (#1218)
• 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)
• Add WeightedIndexTree (#1372, #1444)
• Add PertBuilder to allow specification of mean or mode (#1452)
• Rename Zeta's parameter a to s (#1466)
• Mark WeightError, PoissonError, BinomialError as #[non_exhaustive] (#1480)
• Remove support for usage of isize as a WeightedAliasIndex weight (#1487)
• Change parameter type of Zipf::new: n is now floating-point (#1518)

API changes: renames

• Move Slice -> slice::Choose, EmptySlice -> slice::Empty (#1548)
• Rename trait DistString -> SampleString (#1548)
• Rename DistIter -> Iter, DistMap -> Map (#1548)
• Move {Weight, WeightError, WeightedIndex} -> weighted::{Weight, Error, WeightedIndex} (#1548)
• Move weighted_alias::{AliasableWeight, WeightedAliasIndex} -> weighted::{..} (#1548)
• Move weighted_tree::WeightedTreeIndex -> weighted::WeightedTreeIndex (#1548)

Testing

• Add Kolmogorov Smirnov tests for distributions (#1494, #1504, #1525, #1530)

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)
• Fix Pert distribution where mode is close to (min + max) / 2 (#1452)
• Fix panic in Binomial (#1484)
• Limit the maximal acceptable lambda for Poisson to solve (#1312) (#1498)
• Fix bug in Hypergeometric, this is a Value-breaking change (#1510)

Other changes

• Remove unused fields from Gamma, NormalInverseGaussian and Zipf distributions (#1184) This breaks serialization compatibility with older versions.
