Unreleased

0.5.0 - 2024-09-13

  • Added new 8-bit float types following IEEE 754 convention: ml_dtypes.float8_e4m3, ml_dtypes.float8_e3m4
  • Added the 8-bit floating point type ml_dtypes.float8_e8m0fnu, which is the OpenCompute MX scale format.
  • Added new 4-bit and 6-bit float types: ml_dtypes.float4_e2m1fn, ml_dtypes.float6_e2m3fn and ml_dtypes.float6_e3m2fn.
  • Fix outputs of float divmod and floor_divide when denominator is zero.

0.4.1 - 2024-09-13

  • Updates build requirements to use NumPy 2.0 release

0.4.0 - 2024-04-1

  • Updates ml_dtypes for compatibility with future NumPy 2.0 release.
  • Wheels are built against NumPy 2.0.0rc1.

0.4.0b1 - 2024-03-12

  • Updates ml_dtypes for compatibility with future NumPy 2.0 release.
  • Wheels for the release candidate are built against NumPy 2.0.0b1.

0.3.2 - 2024-01-03

  • Fixed spurious invalid value warnings when casting between floating point types on Mac ARM.
  • Remove pybind11 build requirement
  • Update C++ sources for compatibility with NumPy 2.0

0.3.1 - 2023-09-22

  • Added support for int4 casting to wider integers such as int8
  • Addes support to cast np.float32 and np.float64 into int4

0.3.0 - 2023-09-19

  • Dropped support for Python 3.8, following NEP 29.
  • Added support for Python 3.12.
  • Removed deprecated name ml_dtypes.float8_e4m3b11; use ml_dtypes.float8_e4m3b11fnuz instead.

0.2.0 - 2023-06-06

  • New features:

    • added new 4-bit integer types: ml_dtypes.int4 and ml_dtypes.uint4

  • Deprecations:

    • ml_dtypes.float8_e4m3b11 has been renamed to ml_dtypes.float8_e4m3b11fnuz for more consistency with other dtype names. The former name will still be available until version 0.3.0, but will raise a deprecation warning.

0.1.0 - 2023-04-11

  • Initial release
