+## [0.5.0] - Unreleased
+
+### Crate features and organisation
+- Minimum Rust version update: 1.22.0. (#239)
+- Create a seperate `rand-core` crate. (#288)

+- Add `log` feature. Logging is now available in `JitterRng`, `OsRng`, `EntropyRng` and `ReseedingRng`. (#246)
+- Add `serde-1` feature for some PRNGs. (#189)
+
+### `Rng` trait
+- Split `Rng` in `RngCore` and `Rng` extension trait.
+  `next_u32`, `next_u64` and `fill_bytes` are now part of `RngCore`. (#265)
+- Add `Rng::sample`. (#256)
+- Deprecate `Rng::gen_weighted_bool`. (#308)
+- Add `Rng::gen_bool`. (#308)
+- Remove `Rng::next_f32` and `Rng::next_f64`. (#273)
+- Add optimized `Rng::fill` and `Rng::try_fill` methods. (#247)
+- Deprecate `Rng::gen_iter`. (#286)
+- Deprecate `Rng::gen_ascii_chars`. (#279)
+
+### `rand-core` crate
+(changes included here because they greatly influence the Rand crate)
+- `RngCore` and `SeedableRng` are now part of `rand-core`. (#288)
+- Add modules to help implementing RNGs `impl` and `le`. (#209, #228)
+- Add `Error` and `ErrorKind`. (#225)
+- Add `CryptoRng` marker trait. (#273)
+- Add `BlockRngCore` trait. (#281)
+- Add `BlockRng` wrapper to help implementations. (#281)
+- Revise the `SeedableRng` trait. (#233)
+- Remove default implementations for `RngCore::next_u64` and `RngCore::fill_bytes`. (#288)
+- Add `RngCore::try_fill_bytes`. (#225)
+
+### Other traits and types
+- Add `NewRng` trait. (#233)
+- Add `SmallRng` wrapper. (#296)
+- Rewrite `ReseedingRng` to only work with `BlockRngCore` (substantial performance improvement). (#281)
+- Deprecate `weak_rng`. Use `SmallRng` instead. (#296)
+- Deprecate `random`. (#296)
+- Deprecate `AsciiGenerator`. (#279)
+
+### Random number generators
+- Switch `StdRng` and `thread_rng` to HC-128. (#277)
+- Change `thread_rng` reseeding threshold to 32 MiB. (#277)
+- PRNGs no longer implement `Copy`. (#209)
+- `Debug` implementations no longer show internals. (#209)
+- Implement serialisation for `XorShiftRng`, `IsaacRng` and `Isaac64Rng` under the `serde-1` feature. (#189)
+- Implement `BlockRngCore` for `ChaChaCore` and `Hc128Core`. (#281)
+- All PRNGs are now portable across big- and little-endian architectures. (#209)
+- `Isaac64Rng::next_u32` no longer throws away half the results. (#209)
+- Add `IsaacRng::new_from_u64` and `Isaac64Rng::new_from_u64`. (#209)
+- Remove `IsaacWordRng` wrapper. (#277)
+- Add the HC-128 CSPRNG `Hc128Rng`. (#210)
+- Add `ChaChaRng::set_rounds` method. (#243)
+- Changes to `JitterRng` to get its size down from 2112 to 24 bytes. (#251)
+- Various performance improvements to all PRNGs.
+
+### Platform support and `OsRng`
+- Add support for CloudABI. (#224)
+- Remove support for NaCl. (#225)
+- Replace stubs with proper WASM support in `OsRng`. (#272)
+- On systems that do not have a syscall interface, only keep a single file descriptor open for `OsRng`. (#239)
+- Better error handling and reporting in `OsRng` (using new error type). (#225)
+- `OsRng` now uses non-blocking when available. (#225)
+- Add `EntropyRng`, which provides `OsRng`, but has `JitterRng` as a fallback. (#235)
+
+### Distributions
+- New `Distribution` trait. (#256)
+- Deprecate `Rand`, `Sample` and `IndependentSample` traits. (#256)
+- Add a `Uniform` distribution (replaces most `Rand` implementations). (#256)
+- Add `Binomial` and `Poisson` distributions. (#96)
+- Add `Alphanumeric` distribution. (#279)
+- Remove `Open01` and `Closed01` distributions, use `Uniform` instead (open distribution). (#274)
+- Rework `Range` type, making it possible to implement it for user types. (#274)
+- Add `Range::new_inclusive` for inclusive ranges. (#274)
+- Add `Range::sample_single` to allow for optimized implementations. (#274)
+- Use widening multiply method for much faster integer range reduction. (#274)
