For example, a + factorial can now be simply: `let f: BigUint = (1u32..1000).product();` +- [`BigInt` now supports two's-complement logic operations][26], namely + `BitAnd`, `BitOr`, `BitXor`, and `Not`.

The `rustc-serialize` crate is no longer supported by `num-bigint`. +- [The `rand` dependency has been updated to 0.5][48], now disabled by default. + This requires rustc 1.22 or greater for `rand`'s own requirement. +- [`Shr for BigInt` now rounds down][8] rather than toward zero, matching the + behavior of the primitive integers for negative values. +- [`ParseBigIntError` is now an opaque type][37]. +- [The `big_digit` module is no longer public][38], nor are the `BigDigit` and + `DoubleBigDigit` types and `ZERO_BIG_DIGIT` constant that were re-exported in + the crate root. Public APIs which deal in digits, like `BigUint::from_slice`, + will now always be base-`u32`. + +**Contributors**: @clarcharr, @cuviper, @dodomorandi, @tiehuis, @tspiteri + +[8]: https://github.com/rust-num/num-bigint/pull/8 +[22]: https://github.com/rust-num/num-bigint/pull/22 +[23]: https://github.com/rust-num/num-bigint/pull/23 +[24]: https://github.com/rust-num/num-bigint/pull/24 +[26]: https://github.com/rust-num/num-bigint/pull/26 +[37]: https://github.com/rust-num/num-bigint/pull/37 +[38]: https://github.com/rust-num/num-bigint/pull/38 +[41]: https://github.com/rust-num/num-bigint/pull/41 +[44]: https://github.com/rust-num/num-bigint/pull/44 +[46]: https://github.com/rust-num/num-bigint/pull/46 +[48]: https://github.com/rust-num/num-bigint/pull/48 +[49]: https://github.com/rust-num/num-bigint/pull/49 + +# Release 0.1.44 (2018-05-14) + +- [Division with single-digit divisors is now much faster.][42] +- The README now compares [`ramp`, `rug`, `rust-gmp`][20], and [`apint`][21]. + +**Contributors**: @cuviper, @Robbepop + +[20]: https://github.com/rust-num/num-bigint/pull/20 +[21]: https://github.com/rust-num/num-bigint/pull/21 +[42]: https://github.com/rust-num/num-bigint/pull/42 + +# Release 0.1.43 (2018-02-08) + +- [The new `BigInt::modpow`][18] performs signed modular exponentiation, using + the existing `BigUint::modpow` and rounding negatives similar to `mod_floor`. + +**Contributors**: @cuviper + +[18]: https://github.com/rust-num/num-bigint/pull/18 + + +# Release 0.1.42 (2018-02-07) + +- [num-bigint now has its own source repository][num-356] at [rust-num/num-bigint][home]. +- [`lcm` now avoids creating a large intermediate product][num-350]. +- [`gcd` now uses Stein's algorithm][15] with faster shifts instead of division. +- [`rand` support is now extended to 0.4][11] (while still allowing 0.3). + +**Contributors**: @cuviper, @Emerentius, @ignatenkobrain, @mhogrefe + +[home]: https://github.com/rust-num/num-bigint +[num-350]: https://github.com/rust-num/num/pull/350 +[num-356]: https://github.com/rust-num/num/pull/356 +[11]: https://github.com/rust-num/num-bigint/pull/11 +[15]: https://github.com/rust-num/num-bigint/pull/15 + + +# Prior releases + +No prior release notes were kept.
