+## [0.9.0-beta.0] - 2024-11-25
+This is a pre-release. To depend on this version, use `rand = "=0.9.0-beta.0"` to prevent automatic updates (which can be expected to include breaking changes).
 
-## [0.9.0-alpha.1] - 2024-03-18

+### Security and unsafe
+- Policy: "rand is not a crypto library" (#1514)
+- Remove fork-protection from `ReseedingRng` and `ThreadRng`. Instead, it is recommended to call `ThreadRng::reseed` on fork. (#1379)
+- Use `zerocopy` to replace some `unsafe` code (#1349, #1393, #1446, #1502)

 - Fix panic in Binomial (#1484)
-- Move some of the computations in Binomial from `sample` to `new` (#1484)
-- Add Kolmogorov Smirnov test for sampling of `Normal` and `Binomial` (#1494)
-- Add Kolmogorov Smirnov test for more distributions (#1504)
-- Mark `WeightError`, `PoissonError`, `BinomialError` as `#[non_exhaustive]` (#1480).
-- Remove support for generating `isize` and `usize` values with `Standard`, `Uniform` and `Fill` and usage as a `WeightedAliasIndex` weight (#1487)
 - Limit the maximal acceptable lambda for `Poisson` to solve (#1312) (#1498)
 - Fix bug in `Hypergeometric`, this is a Value-breaking change (#1510)
-- Change parameter type of `Zipf::new`: `n` is now floating-point (#1518)
-
-### Added
-- Add plots for `rand_distr` distributions to documentation (#1434)
-- Add `PertBuilder`, fix case where mode ≅ mean (#1452)
-
-## [0.5.0-alpha.1] - 2024-03-18
-- Target `rand` version `0.9.0-alpha.1`
-
-## [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)
+- Add `WeightedIndexTree` (#1372, #1444)
 
 ### Changes
-- Target `rand` version `0.9.0-alpha.0`
+### Other changes
 - Remove unused fields from `Gamma`, `NormalInverseGaussian` and `Zipf` distributions (#1184)
   This breaks serialization compatibility with older versions.
 - `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 `PertBuilder`, fix case where mode ≅ mean (#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)
 
-### 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)
+### Optimizations
+- Move some of the computations in Binomial from `sample` to `new` (#1484)
+
+### Documentation
+- Add plots for `rand_distr` distributions to documentation (#1434)
