Release 0.3.3 (2021-09-03)

• [Use explicit Integer::div_ceil to avoid the new unstable method.][219]

Contributors: @​catenacyber, @​cuviper

Release 0.3.2 (2021-03-04)

• The new BigUint methods count_ones and trailing_ones return the number of 1 bits in the entire value or just its least-significant tail, respectively.
• The new BigInt and BigUint methods bit and set_bit will read and write individual bits of the value. For negative BigInt, bits are determined as if they were in the two's complement representation.
• The from_radix_le and from_radix_be methods now accept empty buffers to represent zero.
• BigInt and BigUint can now iterate digits as u32 or u64, regardless of the actual internal digit size.

Release 0.3.1 (2020-11-03)

• Addition and subtraction now uses intrinsics for performance on x86 and x86_64 when built with Rust 1.33 or later.
• Conversions to_f32 and to_f64 now return infinity for very large numbers, rather than None. This does preserve the sign too, so a large negative BigInt will convert to negative infinity.
• The optional arbitrary feature implements arbitrary::Arbitrary, distinct from quickcheck::Arbitrary.
• The division algorithm has been optimized to reduce the number of temporary allocations and improve the internal guesses at each step.
• BigInt and BigUint will opportunistically shrink capacity if the internal vector is much larger than needed.
