DCHANGELOG.md55 - Added a `serde1` feature and added Serialize/Deserialize to `UniformInt` and `WeightedIndex` (#97…
67 - `rand::distributions::alias_method::WeightedIndex` was moved to `rand_distr::WeightedAliasIndex`.
68 The simpler alternative `rand::distribution::WeightedIndex` remains. (#945)
69 - Improve treatment of rounding errors in `WeightedIndex::update_weights` (#956)
70 - `WeightedIndex`: return error on NaN instead of panic (#1005)
113 - `WeightedIndex`: allow adjusting a sub-set of weights (#866)
149 - Added `distributions::weighted::alias_method::WeightedIndex` for `O(1)` sampling (#692)
246 - Add `WeightedIndex` and `choose_weighted` (#518, #547)
