 - Distribution `Uniform` implements `TryFrom` instead of `From` for ranges (#1229)
 - Optimize distribution `Uniform`: use Canon's method (single sampling) / Lemire's method (distribution sampling) for faster sampling (breaks value stability; #1287)
 - Add `UniformUsize` and use to make `Uniform` for `usize` portable (#1487)
+- Remove support for generating `isize` and `usize` values with `Standard`, `Uniform` (except via `UniformUsize`) and `Fill` and usage as a `WeightedAliasIndex` weight (#1487)
 - Optimize fn `sample_single_inclusive` for floats (+~20% perf) (#1289)
 - Allow `UniformFloat::new` samples and `UniformFloat::sample_single` to yield `high` (#1462)
 - Add impl `DistString` for distributions `Slice<char>` and `Uniform<char>` (#1315)

-Rand libs have inter-dependencies and make use of the
-[semver trick](https://github.com/dtolnay/semver-trick/) in order to make traits
-compatible across crate versions. (This is especially important for `RngCore`
-and `SeedableRng`.) A few crate releases are thus compatibility shims,
-depending on the *next* lib version (e.g. `rand_core` versions `0.2.2` and
-`0.3.1`). This means, for example, that `rand_core_0_4_0::SeedableRng` and
-`rand_core_0_3_0::SeedableRng` are distinct, incompatible traits, which can
-cause build errors. Usually, running `cargo update` is enough to fix any issues.
-
-## Crate Features
-
-`rand_core` supports `no_std` and `alloc`-only configurations, as well as full
-`std` functionality. The differences between `no_std` and full `std` are small,
-comprising `RngCore` support for `Box<R>` types where `R: RngCore`,
-`std::io::Read` support for types supporting `RngCore`, and
-extensions to the `Error` type's functionality.
-
-The `std` feature is *not enabled by default*. This is primarily to avoid build
-problems where one crate implicitly requires `rand_core` with `std` support and
-another crate requires `rand` *without* `std` support. However, the `rand` crate
-continues to enable `std` support by default, both for itself and `rand_core`.
-
-The `serde` feature can be used to derive `Serialize` and `Deserialize` for RNG
-implementations that use the `BlockRng` or `BlockRng64` wrappers.
