The test modules were getting huge, and some of its functions were actually a huge amount of code due to macros, causing tests to take a long time just to compile. They are now separated into a few different tests, and the scalar macros especially are now expanded more sparingly in just a few `check()` functions. Test compile times for me went from about 25 seconds to 1.5s in debug mode, and from 300 seconds (!) to about 8s in release mode.
num-bigint
Big integer types for Rust, BigInt
and BigUint
.

Releases
Release notes are available in RELEASES.md.
Compatibility

crate is tested for rustc 1.8 and greater.
Alternatives
While num-bigint
strives for good performance in pure Rust code, other
crates may offer better performance with different trade-offs. The following
table offers a brief comparison to a few alternatives.
