v0.5.2 release

This is a minor change over v0.5.1. This release reverts the addition of Power wheels, which caused problems with our wheel release process.

Due to an oversight during the release process, the wheels from this release report themselves as v0.5.1. The only difference between the two is the lack of Power wheels.

v0.5.1 release

• Fixed sign bit handling for float4 and float6 types.
• Wheels now support Python 3.13 free-threading.
• Wheels now support the Power architecture.

v0.5.0 release

• 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.

v0.4.1 release

• Updates build requirements to use NumPy 2.0 release

v0.4.0 release

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

v0.4.0b1 pre-release

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

Version 0.3.2 release

• 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

v0.3.1 release

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

Version 0.3.0 Release

• 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.

v0.2.0 Release

Version 0.2.0 release

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.
