| |
| ## [0.8.2] - 2021-01-12 |

| - The minimum supported Rust version is now 1.36 (#1011) |
| - `getrandom` updated to v0.2 (#1041) |
| - Remove `wasm-bindgen` and `stdweb` feature flags. For details of WASM support, |
| see the [getrandom documentation](https://docs.rs/getrandom/latest). (#948) |

| to be used if disabling default crate features) (#948) |
| - `StdRng`: Switch from ChaCha20 to ChaCha12 for better performance (#1028) |
| - `SmallRng`: Replace PCG algorithm with xoshiro{128,256}++ (#1038) |

| - Allow `gen_range` and `Uniform` to work on non-`Copy` types (#506) |
| - `Uniform` supports inclusive ranges: `Uniform::from(a..=b)`. This is |
| automatically enabled for Rust >= 1.27. (#566) |

| - Remove functionality already deprecated in 0.5 (#499) |
| - Support for `i128` and `u128` is automatically enabled for Rust >= 1.26. This |
| renders the `i128_support` feature obsolete. It still exists for backwards |
| compatibility but does not have any effect. This breaks programs using Rand |
| with `i128_support` on nightlies older than Rust 1.26. (#571) |

| runtime is removed from Rust). |
| |
| ### Fixed |
| - Improved performance of ISAAC and ISAAC64 by 30% and 12 % respectively, by |
| informing the optimiser that indexing is never out-of-bounds. |
| |
| ### Removed |
| - Removed the Deprecated `choose_option` |
| |
| |
| ## [Rust 0.11.0] - 2014-07-02 |
| ### Added |
| - document when to use `OSRng` in cryptographic context, and explain why we use `/dev/urandom` instead of `/dev/random` |
| - `Rng::gen_iter()` which will return an infinite stream of random values |
| - `Rng::gen_ascii_chars()` which will return an infinite stream of random ascii characters |
| |
| ### Changed |
| - Now only depends on libcore! |
| - Remove `Rng.choose()`, rename `Rng.choose_option()` to `.choose()` |
| - Rename OSRng to OsRng |
| - The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`, |
| but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice |
| structure now has a lifetime associated with it. |
| - The `sample` method on `Rng` has been moved to a top-level function in the |
| `rand` module due to its dependence on `Vec`. |
| |
| ### Removed |
| - `Rng::gen_vec()` was removed. Previous behavior can be regained with |
| `rng.gen_iter().take(n).collect()` |
| - `Rng::gen_ascii_str()` was removed. Previous behavior can be regained with |
| `rng.gen_ascii_chars().take(n).collect()` |
| - {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all |
| relied on being able to use an OSRng for seeding, but this is no longer |
| available in librand (where these types are defined). To retain the same |
| functionality, these types now implement the `Rand` trait so they can be |
| generated with a random seed from another random number generator. This allows |
| the stdlib to use an OSRng to create seeded instances of these RNGs. |
| - Rand implementations for `Box<T>` and `@T` were removed. These seemed to be |
| pretty rare in the codebase, and it allows for librand to not depend on |
| liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not |
| supported. |
| - Remove a slew of old deprecated functions |
| |
| |
| ## [Rust 0.10] - 2014-04-03 |
| ### Changed |
| - replace `Rng.shuffle's` functionality with `.shuffle_mut` |
| - bubble up IO errors when creating an OSRng |
| |
| ### Fixed |
| - Use `fill()` instead of `read()` |
| - Rewrite OsRng in Rust for windows |
| |
| ## [0.10-pre] - 2014-03-02 |
| ### Added |
| - Seperate `rand` out of the standard library |
