[dependabot]

Updates the requirements on ml-dtypes to permit the latest version.

Release notes

Sourced from ml-dtypes's releases.

v0.5.4

• We now register casts from int2 and int4 to all of the custom float types, except float6_e2m3fn and float8_e8m0fnu.
• Custom floats may now be constructed from Python integers (#317)
• Fixed bug in byte-swap operation for custom floats (#311)
• Wheels now support Python 3.14 free threading on Windows.

Changelog

Sourced from ml-dtypes's changelog.

[0.5.4] - 2025-11-17

• We now register casts from int2 and int4 to all of the custom float types, except float6_e2m3fn and float8_e8m0fnu.
• Custom floats may now be constructed from Python integers (#317)
• Fixed bug in byte-swap operation for custom floats (#311)
• Wheels now support Python 3.14 free threading on Windows.

[0.5.3] - 2025-07-29

• NPY_NEEDS_PYAPI was removed from the dtype flags. This should improve the speed of array operations, but it does mean that values pickled using previous versions of ml_dtypes are incompatible with the current release and should be regenerated with the current release.
• Wheels now support Python 3.14.
• Wheels now support Windows 11 ARM.

[0.5.2] - 2025-01-31

• Dropped support for Power wheels again. These turned out to cause problems in our release process. We will consider readding these if NumPy ships Power wheels.
• Fixed GCC compilation issues related to ambiguous casts.

[0.5.1] - 2025-01-06

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

[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
