num

• Updated num-bigint, num-complex, and num-rational to 0.4.0.
  • Updated to rand 0.8 in num-bigint and num-complex.
  • Rational is deprecated in favor of explicit Rational32 or Rational64.
• As with prior release bumps, all items exported from num-integer, num-iter, and num-traits are still semver-compatible with those exported by earlier version of num.

• Updated all sub-crates to their latest versions.
• Clarify the license specification as "MIT OR Apache-2.0".

All items exported from num-integer, num-iter, and num-traits are still semver-compatible with those exported by num 0.1 and 0.2. If you have these as public dependencies in your own crates, it is not a breaking change to move to num 0.3. However, this is not true of num-bigint, num-complex, or num-rational, as those exported items are distinct in this release.

Enhancements

• Updates to num-integer, num-iter, and num-traits are still compatible with num 0.1 and 0.2.
• The "alloc" feature enables bigint without std on Rust 1.36+.
• The "libm" feature enables Float without std in traits and complex.
• Please see the release notes of the individual sub-crates for details.

Breaking Changes

• num now requires rustc 1.31 or greater.
  • The "i128" opt-in feature was removed, now always available.
• rand support has been updated to 0.7, requiring Rust 1.32.

All items exported from num-integer, num-iter, and num-traits are still semver-compatible with those exported by num 0.1. If you have these as public dependencies in your own crates, it is not a breaking change to move to num 0.2. However, this is not true of num-bigint, num-complex, or num-rational, as those exported items are distinct in this release.

A few common changes are listed below, but most of the development happens in the individual sub-crates. Please consult their release notes for more details about recent changes: num-bigint, num-complex, num-integer, num-iter, num-rational, and num-traits.

Enhancements

• Updates to num-integer, num-iter, and num-traits are still compatible with num 0.1.
• 128-bit integers are supported with Rust 1.26 and later.
• BigInt, BigUint, Complex, and Ratio all implement Sum and Product.

Breaking Changes

• num now requires rustc 1.15 or greater.
• num-bigint, num-complex, and num-rational have all been updated to 0.2.
• It's no longer possible to toggle individual num-* sub-crates using cargo features. If you need that control, please use those crates directly.
• There is now a std feature, enabled by default, along with the implication that building without this feature makes this a #![no_std] crate. num::bigint is not available without std, and the other sub-crates may have limited functionality.
• The serde dependency has been updated to 1.0, still disabled by default. The rustc-serialize crate is no longer supported by num.
• The rand dependency has been updated to 0.5, now disabled by default. This requires rustc 1.22 or greater for rand's own requirement.

• All of the num sub-crates now have their own source repositories.
• Updated num sub-crates to their latest versions.
