NumPy 2.0.0 is the first major release since 2006. It is the result of
11 months of development since the last feature release and is the work
of 212 contributors spread over 1078 pull requests. It contains a large
number of exciting new features as well as changes to both the Python
and C APIs.
This major release includes breaking changes that could not happen in a
regular minor (feature) release - including an ABI break, changes to
type promotion rules, and API changes which may not have been emitting
deprecation warnings in 1.26.x. Key documents related to how to adapt to
changes in NumPy 2.0, in addition to these release notes, include:
A new variable-length string dtype, numpy.dtypes.StringDType and a new
numpy.strings namespace with performant ufuncs for string operations,
Support for float32 and longdouble in all
numpy.fft functions,
Support for the array API standard in the main numpy
namespace.
Performance improvements:
Sorting functions sort, argsort,
partition, argpartition have been
accelerated through the use of the Intel x86-simd-sort and
Google Highway libraries, and may see large (hardware-specific)
speedups,
macOS Accelerate support and binary wheels for macOS >=14, with
significant performance improvements for linear algebra
operations on macOS, and wheels that are about 3 times smaller,
numpy.char fixed-length string operations have
been accelerated by implementing ufuncs that also support
numpy.dtypes.StringDType in addition to the
fixed-length string dtypes,
A new tracing and introspection API,
numpy.lib.introspect.opt_func_info, to determine
which hardware-specific kernels are available and will be
dispatched to.
numpy.save now uses pickle protocol version 4 for saving
arrays with object dtype, which allows for pickle objects larger
than 4GB and improves saving speed by about 5% for large arrays.
Python API improvements:
