Fixed

v2.3.0

Compare Source

Added

• Support for Kani Rust Verifier. By [@​cameron1024].
• Support for rand_distr::Distribution implementations behind rand_distr optional cargo
  feature. By [@​coreylowman].
• Floating point formatting options in Display and Debug implementations. By [@​eiz].

Changed

• Breaking Change Minimum supported Rust version is now 1.70.
• Breaking Change Minimum supported Rust version policy reverted to original policy of allowing
  minimum supported Rust version updates for minor releases instead of only major to avoid
  segmentation and allow optimizing hardware implementations without unnecessary major releases.
• Hardware intrinsics/assembly is finally available on stable Rust, including using hardware
  feature detection (std only), including:
  • AArch64 now uses FP16 hardware instructions for conversions and math operations when
    available.
  • x86/x86-64 now uses F16C hardware instructions for conversions (but no math operations) when
    available. Fixes [#​54].

Deprecated

• use-intrinsics cargo feature no longer used. Hardware support will now always be used whenever
  possible. A future version may output deprecation warnings if this feature is enabled.

Fixed

• Improve code generation of leading_zeros functions by inlining. By [@​encounter].
• Sum implementation of bf16 incorrectly performed product instead of sum. By [@​wx-csy].
• Compile failed when serde cargo feature enabled but std not enabled.
• Incorrect black boxing of benchmark tests.
• Rustdoc cfg display on docs.rs not getting enabled.

Changed
