SciPy 1.14.0 Release Notes

SciPy 1.14.0 is the culmination of 3 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.14.x branch, and on adding new features on the main branch.

This release requires Python 3.10+ and NumPy 1.23.5 or greater.

For running on PyPy, PyPy3 6.0+ is required.

Highlights of this release

• SciPy now supports the new Accelerate library introduced in macOS 13.3, and
  has wheels built against Accelerate for macOS >=14 resulting in significant
  performance improvements for many linear algebra operations.
• A new method, cobyqa, has been added to scipy.optimize.minimize - this
  is an interface for COBYQA (Constrained Optimization BY Quadratic
  Approximations), a derivative-free optimization solver, designed to
  supersede COBYLA, developed by the Department of Applied Mathematics, The
  Hong Kong Polytechnic University.
• scipy.sparse.linalg.spsolve_triangular is now more than an order of
  magnitude faster in many cases.

New features

scipy.fft improvements

• A new function, scipy.fft.prev_fast_len, has been added. This function
  finds the largest composite of FFT radices that is less than the target
  length. It is useful for discarding a minimal number of samples before FFT.

scipy.io improvements

• wavfile now supports reading and writing of wav files in the RF64
  format, allowing files greater than 4 GB in size to be handled.

scipy.constants improvements

• Experimental support for the array API standard has been added.

scipy.interpolate improvements

• scipy.interpolate.Akima1DInterpolator now supports extrapolation via the
  extrapolate argument.

scipy.optimize improvements

• scipy.optimize.HessianUpdateStrategy now also accepts square arrays for
  init_scale.
• A new method, cobyqa, has been added to scipy.optimize.minimize - this
  is an interface for COBYQA (Constrained Optimization BY Quadratic
  Approximations), a derivative-free optimization solver, designed to
  supersede COBYLA, developed by the Department of Applied Mathematics, The
  Hong Kong Polytechnic University.
• There are some performance improvements in
  scipy.optimize.differential_evolution.
• scipy.optimize.approx_fprime now has linear space complexity.

scipy.signal improvements

• scipy.signal.minimum_phase has a new argument half, allowing the
  provision of a filter of the same length as the linear-phase FIR filter
  coefficients and with the same magnitude spectrum.

scipy.sparse improvements

• Sparse arrays now support 1D shapes in COO, DOK and CSR formats.
  These are all the formats we currently intend to support 1D shapes.
  Other sparse array formats raise an exception for 1D input.
• Sparse array methods min/nanmin/argmin and max analogs now return 1D arrays.
  Results are still COO format sparse arrays for min/nanmin and
  dense np.ndarray for argmin.
• Sparse matrix and array objects improve their repr and str output.
• A special case has been added to handle multiplying a dia_array by a
  scalar, which avoids a potentially costly conversion to CSR format.
• scipy.sparse.csgraph.yen has been added, allowing usage of Yen's K-Shortest
  Paths algorithm on a directed on undirected graph.
• Addition between DIA-format sparse arrays and matrices is now faster.
• scipy.sparse.linalg.spsolve_triangular is now more than an order of
  magnitude faster in many cases.

scipy.spatial improvements

• Rotation supports an alternative "scalar-first" convention of quaternion
  component ordering. It is available via the keyword argument scalar_first
  of from_quat and as_quat methods.
• Some minor performance improvements for inverting of Rotation objects.

scipy.special improvements

• Added scipy.special.log_wright_bessel, for calculation of the logarithm of
  Wright's Bessel function.
• The relative error in scipy.special.hyp2f1 calculations has improved
  substantially.
• Improved behavior of boxcox, inv_boxcox, boxcox1p, and
  inv_boxcox1p by preventing premature overflow.

scipy.stats improvements

• A new function scipy.stats.power can be used for simulating the power
  of a hypothesis test with respect to a specified alternative.
• The Irwin-Hall (AKA Uniform Sum) distribution has been added as
  scipy.stats.irwinhall.
• Exact p-value calculations of scipy.stats.mannwhitneyu are much faster
  and use less memory.
• scipy.stats.pearsonr now accepts n-D arrays and computes the statistic
  along a specified axis.
• scipy.stats.kstat, scipy.stats.kstatvar, and scipy.stats.bartlett
  are faster at performing calculations along an axis of a large n-D array.

Array API Standard Support

Experimental support for array libraries other than NumPy has been added to
existing sub-packages in recent versions of SciPy. Please consider testing
these features by setting an environment variable SCIPY_ARRAY_API=1 and
providing PyTorch, JAX, or CuPy arrays as array arguments.

As of 1.14.0, there is support for

• scipy.cluster

  • scipy.stats.kurtosistest
  • scipy.stats.normaltest
  • scipy.stats.jarque_bera
  • scipy.stats.bartlett
  • scipy.stats.power_divergence
  • scipy.stats.monte_carlo_test

Deprecated features

• scipy.stats.gstd, scipy.stats.chisquare, and
  scipy.stats.power_divergence have deprecated support for masked array
  input.
• scipy.stats.linregress has deprecated support for specifying both samples
  in one argument; x and y are to be provided as separate arguments.
• The conjtransp method for scipy.sparse.dok_array and
  scipy.sparse.dok_matrix has been deprecated and will be removed in SciPy
  1.16.0.
• The option quadrature="trapz" in scipy.integrate.quad_vec has been
  deprecated in favour of quadrature="trapezoid" and will be removed in
  SciPy 1.16.0.
• scipy.special.{comb,perm} have deprecated support for use of exact=True in
  conjunction with non-integral N and/or k.

Backwards incompatible changes

• Many scipy.stats functions now produce a standardized warning message when
  an input sample is too small (e.g. zero size). Previously, these functions
  may have raised an error, emitted one or more less informative warnings, or
  emitted no warnings. In most cases, returned results are unchanged; in almost
  all cases the correct result is NaN.

Expired deprecations

There is an ongoing effort to follow through on long-standing deprecations.
The following previously deprecated features are affected:

• Several previously deprecated methods for sparse arrays were removed:
  asfptype, getrow, getcol, get_shape, getmaxprint,
  set_shape, getnnz, and getformat. Additionally, the .A and
  .H attributes were removed.

• scipy.integrate.{simps,trapz,cumtrapz} have been removed in favour of
  simpson, trapezoid, and cumulative_trapezoid.

• The tol argument of scipy.sparse.linalg.{bcg,bicstab,cg,cgs,gcrotmk, mres,lgmres,minres,qmr,tfqmr} has been removed in favour of rtol.
  Furthermore, the default value of atol for these functions has changed
  to 0.0.

• The restrt argument of scipy.sparse.linalg.gmres has been removed in
  favour of restart.

• The initial_lexsort argument of scipy.stats.kendalltau has been
  removed.

• The cond and rcond arguments of scipy.linalg.pinv have been
  removed.

• The even argument of scipy.integrate.simpson has been removed.

• The turbo and eigvals arguments from scipy.linalg.{eigh,eigvalsh}
  have been removed.

• The legacy argument of scipy.special.comb has been removed.

• The hz/nyq argument of signal.{firls, firwin, firwin2, remez} has
  been removed.

• Objects that weren't part of the public interface but were accessible through
  deprecated submodules have been removed.

• float128, float96, and object arrays now raise an error in
  scipy.signal.medfilt and scipy.signal.order_filter.

• scipy.interpolate.interp2d has been replaced by an empty stub (to be
  removed completely in the future).

• Coinciding with changes to function signatures (e.g. removal of a deprecated
  keyword), we had deprecated positional use of keyword arguments for the
  affected functions, which will now raise an error. Affected functions are:

  • sparse.linalg.{bicg, bicgstab, cg, cgs, gcrotmk, gmres, lgmres, minres, qmr, tfqmr}
  • stats.kendalltau
  • linalg.pinv
  • integrate.simpson
  • linalg.{eigh,eigvalsh}
  • special.comb
  • signal.{firls, firwin, firwin2, remez}

Other changes

• SciPy now uses C17 as the C standard to build with, instead of C99. The C++
  standard remains C++17.
• macOS Accelerate, which got a major upgrade in macOS 13.3, is now supported.
  This results in significant performance improvements for linear algebra
  operations, as well as smaller binary wheels.
• Cross-compilation should be smoother and QEMU or similar is no longer needed
  to run the cross interpreter.
• Experimental array API support for the JAX backend has been added to several
  parts of SciPy.

SciPy 1.13.0 Release Notes

SciPy 1.13.0 is the culmination of 3 months of hard work. This
out-of-band release aims to support NumPy 2.0.0, and is backwards
compatible to NumPy 1.22.4. The version of OpenBLAS used to build
the PyPI wheels has been increased to 0.3.26.dev.

This release requires Python 3.9+ and NumPy 1.22.4 or greater.

For running on PyPy, PyPy3 6.0+ is required.

Highlights of this release

• Support for NumPy 2.0.0.
• Interactive examples have been added to the documentation, allowing users
  to run the examples locally on embedded Jupyterlite notebooks in their
  browser.
• Preliminary 1D array support for the COO and DOK sparse formats.
• Several scipy.stats functions have gained support for additional
  axis, nan_policy, and keepdims arguments. scipy.stats also
  has several performance and accuracy improvements.

New features

scipy.integrate improvements

• The terminal attribute of scipy.integrate.solve_ivp events
  callables now additionally accepts integer values to specify a number
  of occurrences required for termination, rather than the previous restriction
  of only accepting a bool value to terminate on the first registered
  event.

scipy.io improvements

• scipy.io.wavfile.write has improved dtype input validation.

scipy.interpolate improvements

• The Modified Akima Interpolation has been added to
  interpolate.Akima1DInterpolator, available via the new method
  argument.
• New method BSpline.insert_knot inserts a knot into a BSpline instance.
  This routine is similar to the module-level scipy.interpolate.insert
  function, and works with the BSpline objects instead of tck tuples.
• RegularGridInterpolator gained the functionality to compute derivatives
  in place. For instance, RegularGridInterolator((x, y), values, method="cubic")(xi, nu=(1, 1)) evaluates the mixed second derivative,
  :math:\partial^2 / \partial x \partial y at xi.
• Performance characteristics of tensor-product spline methods of
  RegularGridInterpolator have been changed: evaluations should be
  significantly faster, while construction might be slower. If you experience
  issues with construction times, you may need to experiment with optional
  keyword arguments solver and solver_args. Previous behavior (fast
  construction, slow evaluations) can be obtained via "*_legacy" methods:
  method="cubic_legacy" is exactly equivalent to method="cubic" in
  previous releases. See gh-19633 for details.

scipy.signal improvements

• Many filter design functions now have improved input validation for the
  sampling frequency (fs).

scipy.sparse improvements

• coo_array now supports 1D shapes, and has additional 1D support for
  min, max, argmin, and argmax. The DOK format now has
  preliminary 1D support as well, though only supports simple integer indices
  at the time of writing.
• Experimental support has been added for pydata/sparse array inputs to
  scipy.sparse.csgraph.
• dok_array and dok_matrix now have proper implementations of
  fromkeys.
• csr and csc formats now have improved setdiag performance.

scipy.spatial improvements

• voronoi_plot_2d now draws Voronoi edges to infinity more clearly
  when the aspect ratio is skewed.

scipy.special improvements

• All Fortran code, namely, AMOS, specfun, and cdflib libraries
  that the majority of special functions depend on, is ported to Cython/C.
• The function factorialk now also supports faster, approximate
  calculation using exact=False.

scipy.stats improvements

• scipy.stats.rankdata and scipy.stats.wilcoxon have been vectorized,
  improving their performance and the performance of hypothesis tests that
  depend on them.
• stats.mannwhitneyu should now be faster due to a vectorized statistic
  calculation, improved caching, improved exploitation of symmetry, and a
  memory reduction. PermutationMethod support was also added.
• scipy.stats.mood now has nan_policy and keepdims support.
• scipy.stats.brunnermunzel now has axis and keepdims support.
• scipy.stats.friedmanchisquare, scipy.stats.shapiro,
  scipy.stats.normaltest, scipy.stats.skewtest,
  scipy.stats.kurtosistest, scipy.stats.f_oneway,
  scipy.stats.alexandergovern, scipy.stats.combine_pvalues, and
  scipy.stats.kstest have gained axis, nan_policy and
  keepdims support.
• scipy.stats.boxcox_normmax has gained a ymax parameter to allow user
  specification of the maximum value of the transformed data.
• scipy.stats.vonmises pdf method has been extended to support
  kappa=0. The fit method is also more performant due to the use of
  non-trivial bounds to solve for kappa.
• High order moment calculations for scipy.stats.powerlaw are now more
  accurate.
• The fit methods of scipy.stats.gamma (with method='mm') and
  scipy.stats.loglaplace are faster and more reliable.
• scipy.stats.goodness_of_fit now supports the use of a custom statistic
  provided by the user.
• scipy.stats.wilcoxon now supports PermutationMethod, enabling
  calculation of accurate p-values in the presence of ties and zeros.
• scipy.stats.monte_carlo_test now has improved robustness in the face of
  numerical noise.
• scipy.stats.wasserstein_distance_nd was introduced to compute the
  Wasserstein-1 distance between two N-D discrete distributions.

Deprecated features

• Complex dtypes in PchipInterpolator and Akima1DInterpolator have
  been deprecated and will raise an error in SciPy 1.15.0. If you are trying
  to use the real components of the passed array, use np.real on y.

Backwards incompatible changes

Other changes

• The second argument of scipy.stats.moment has been renamed to order
  while maintaining backward compatibility.

SciPy 1.12.0 Release Notes

SciPy 1.12.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.12.x branch, and on adding new features on the main branch.

This release requires Python 3.9+ and NumPy 1.22.4 or greater.

For running on PyPy, PyPy3 6.0+ is required.

Highlights of this release

• Experimental support for the array API standard has been added to part of
  scipy.special, and to all of scipy.fft and scipy.cluster. There are
  likely to be bugs and early feedback for usage with CuPy arrays, PyTorch
  tensors, and other array API compatible libraries is appreciated. Use the
  SCIPY_ARRAY_API environment variable for testing.
• A new class, ShortTimeFFT, provides a more versatile implementation of the
  short-time Fourier transform (STFT), its inverse (ISTFT) as well as the (cross-)
  spectrogram. It utilizes an improved algorithm for calculating the ISTFT.
• Several new constructors have been added for sparse arrays, and many operations
  now additionally support sparse arrays, further facilitating the migration
  from sparse matrices.
• A large portion of the scipy.stats API now has improved support for handling
  NaN values, masked arrays, and more fine-grained shape-handling. The
  accuracy and performance of a number of stats methods have been improved,
  and a number of new statistical tests and distributions have been added.

New features

scipy.cluster improvements

• Experimental support added for the array API standard; PyTorch tensors,
  CuPy arrays and array API compatible array libraries are now accepted
  (GPU support is limited to functions with pure Python implementations).
  CPU arrays which can be converted to and from NumPy are supported
  module-wide and returned arrays will match the input type.
  This behaviour is enabled by setting the SCIPY_ARRAY_API environment
  variable before importing scipy. This experimental support is still
  under development and likely to contain bugs - testing is very welcome.

scipy.fft improvements

• Experimental support added for the array API standard; functions which are
  part of the fft array API standard extension module, as well as the
  Fast Hankel Transforms and the basic FFTs which are not in the extension
  module, now accept PyTorch tensors, CuPy arrays and array API compatible
  array libraries. CPU arrays which can be converted to and from NumPy arrays
  are supported module-wide and returned arrays will match the input type.
  This behaviour is enabled by setting the SCIPY_ARRAY_API environment
  variable before importing scipy. This experimental support is still under
  development and likely to contain bugs - testing is very welcome.

scipy.integrate improvements

• Added scipy.integrate.cumulative_simpson for cumulative quadrature
  from sampled data using Simpson's 1/3 rule.

scipy.interpolate improvements

• New class NdBSpline represents tensor-product splines in N dimensions.
  This class only knows how to evaluate a tensor product given coefficients
  and knot vectors. This way it generalizes BSpline for 1D data to N-D, and
  parallels NdPPoly (which represents N-D tensor product polynomials).
  Evaluations exploit the localized nature of b-splines.
• NearestNDInterpolator.__call__ accepts **query_options, which are
  passed through to the KDTree.query call to find nearest neighbors. This
  allows, for instance, to limit the neighbor search distance and parallelize
  the query using the workers keyword.
• BarycentricInterpolator now allows computing the derivatives.
• It is now possible to change interpolation values in an existing
  CloughTocher2DInterpolator instance, while also saving the barycentric
  coordinates of interpolation points.

scipy.linalg improvements

• Access to new low-level LAPACK functions is provided via dtgsyl and
  stgsyl.

scipy.optimize improvements

• scipy.optimize.isotonic_regression has been added to allow nonparametric isotonic
  regression.
• scipy.optimize.nnls is rewritten in Python and now implements the so-called
  fnnls or fast nnls, making it more efficient for high-dimensional problems.
• The result object of scipy.optimize.root and scipy.optimize.root_scalar
  now reports the method used.
• The callback method of scipy.optimize.differential_evolution can now be
  passed more detailed information via the intermediate_results keyword
  parameter. Also, the evolution strategy now accepts a callable for
  additional customization. The performance of differential_evolution has
  also been improved.
• scipy.optimize.minimize method Newton-CG now supports functions that
  return sparse Hessian matrices/arrays for the hess parameter and is slightly
  more efficient.
• scipy.optimize.minimize method BFGS now accepts an initial estimate for the
  inverse of the Hessian, which allows for more efficient workflows in some
  circumstances. The new parameter is hess_inv0.
• scipy.optimize.minimize methods CG, Newton-CG, and BFGS now accept
  parameters c1 and c2, allowing specification of the Armijo and curvature rule
  parameters, respectively.
• scipy.optimize.curve_fit performance has improved due to more efficient memoization
  of the callable function.

scipy.signal improvements

• freqz, freqz_zpk, and group_delay are now more accurate
  when fs has a default value.
• The new class ShortTimeFFT provides a more versatile implementation of the
  short-time Fourier transform (STFT), its inverse (ISTFT) as well as the (cross-)
  spectrogram. It utilizes an improved algorithm for calculating the ISTFT based on
  dual windows and provides more fine-grained control of the parametrization especially
  in regard to scaling and phase-shift. Functionality was implemented to ease
  working with signal and STFT chunks. A section has been added to the "SciPy User Guide"
  providing algorithmic details. The functions stft, istft and spectrogram
  have been marked as legacy.

scipy.sparse improvements

• sparse.linalg iterative solvers sparse.linalg.cg,
  sparse.linalg.cgs, sparse.linalg.bicg, sparse.linalg.bicgstab,
  sparse.linalg.gmres, and sparse.linalg.qmr are rewritten in Python.
• Updated vendored SuperLU version to 6.0.1, along with a few additional
  fixes.
• Sparse arrays have gained additional constructors: eye_array,
  random_array, block_array, and identity. kron and kronsum
  have been adjusted to additionally support operation on sparse arrays.
• Sparse matrices now support a transpose with axes=(1, 0), to mirror
  the .T method.
• LaplacianNd now allows selection of the largest subset of eigenvalues,
  and additionally now supports retrieval of the corresponding eigenvectors.
  The performance of LaplacianNd has also been improved.
• The performance of dok_matrix and dok_array has been improved,
  and their inheritance behavior should be more robust.
• hstack, vstack, and block_diag now work with sparse arrays, and
  preserve the input sparse type.
• A new function, scipy.sparse.linalg.matrix_power, has been added, allowing
  for exponentiation of sparse arrays.

scipy.spatial improvements

• Two new methods were implemented for spatial.transform.Rotation:
  __pow__ to raise a rotation to integer or fractional power and
  approx_equal to check if two rotations are approximately equal.
• The method Rotation.align_vectors was extended to solve a constrained
  alignment problem where two vectors are required to be aligned precisely.
  Also when given a single pair of vectors, the algorithm now returns the
  rotation with minimal magnitude, which can be considered as a minor
  backward incompatible change.
• A new representation for spatial.transform.Rotation called Davenport
  angles is available through from_davenport and as_davenport methods.
• Performance improvements have been added to distance.hamming and
  distance.correlation.
• Improved performance of SphericalVoronoi sort_vertices_of_regions
  and two dimensional area calculations.

scipy.special improvements

• Added scipy.special.stirling2 for computation of Stirling numbers of the
  second kind. Both exact calculation and an asymptotic approximation
  (the default) are supported via exact=True and exact=False (the
  default) respectively.
• Added scipy.special.betaincc for computation of the complementary
  incomplete Beta function and scipy.special.betainccinv for computation of
  its inverse.
• Improved precision of scipy.special.betainc and scipy.special.betaincinv.
• Experimental support added for alternative backends: functions
  scipy.special.log_ndtr, scipy.special.ndtr, scipy.special.ndtri,
  scipy.special.erf, scipy.special.erfc, scipy.special.i0,
  scipy.special.i0e, scipy.special.i1, scipy.special.i1e,
  scipy.special.gammaln, scipy.special.gammainc, scipy.special.gammaincc,
  scipy.special.logit, and scipy.special.expit now accept PyTorch tensors
  and CuPy arrays. These features are still under development and likely to
  contain bugs, so they are disabled by default; enable them by setting a
  SCIPY_ARRAY_API environment variable to 1 before importing scipy.
  Testing is appreciated!

scipy.stats improvements

• Added scipy.stats.quantile_test, a nonparametric test of whether a
  hypothesized value is the quantile associated with a specified probability.
  The confidence_interval method of the result object gives a confidence
  interval of the quantile.
• scipy.stats.sampling.FastGeneratorInversion provides a convenient
  interface to fast random sampling via numerical inversion of distribution
  CDFs.
• scipy.stats.geometric_discrepancy adds geometric/topological discrepancy
  metrics for random samples.
• scipy.stats.multivariate_normal now has a fit method for fitting
  distribution parameters to data via maximum likelihood estimation.
• scipy.stats.bws_test performs the Baumgartner-Weiss-Schindler test of
  whether two-samples were drawn from the same distribution.
• scipy.stats.jf_skew_t implements the Jones and Faddy skew-t distribution.
• scipy.stats.anderson_ksamp now supports a permutation version of the test
  using the method parameter.
• The fit methods of scipy.stats.halfcauchy, scipy.stats.halflogistic, and
  scipy.stats.halfnorm are faster and more accurate.
• scipy.stats.beta entropy accuracy has been improved for extreme values of
  distribution parameters.
• The accuracy of sf and/or isf methods have been improved for
  several distributions: scipy.stats.burr, scipy.stats.hypsecant,
  scipy.stats.kappa3, scipy.stats.loglaplace, scipy.stats.lognorm,
  scipy.stats.lomax, scipy.stats.pearson3, scipy.stats.rdist, and
  scipy.stats.pareto.
• The following functions now support parameters axis, nan_policy, and
  keep_dims: scipy.stats.entropy, scipy.stats.differential_entropy,
  scipy.stats.variation, scipy.stats.ansari, scipy.stats.bartlett,
  scipy.stats.levene, scipy.stats.fligner, scipy.stats.circmean,
  scipy.stats.circvar, scipy.stats.circstd, scipy.stats.tmean,
  scipy.stats.tvar, scipy.stats.tstd, scipy.stats.tmin, scipy.stats.tmax,
  and scipy.stats.tsem.
• The logpdf and fit methods of scipy.stats.skewnorm have been improved.
• The beta negative binomial distribution is implemented as scipy.stats.betanbinom.
• Improved performance of scipy.stats.invwishart rvs and logpdf.
• A source of intermediate overflow in scipy.stats.boxcox_normmax with
  method='mle' has been eliminated, and the returned value of lmbda is
  constrained such that the transformed data will not overflow.
• scipy.stats.nakagami stats is more accurate and reliable.
• A source of intermediate overflow in scipy.norminvgauss.pdf has been eliminated.
• Added support for masked arrays to scipy.stats.circmean, scipy.stats.circvar,

• Improved accuracy of entropy method of scipy.stats.multivariate_t for large
  degrees of freedom.
• scipy.stats.loggamma has an improved entropy method.

Deprecated features

• Error messages have been made clearer for objects that don't exist in the
  public namespace and warnings sharpened for private attributes that are not
  supposed to be imported at all.

• scipy.signal.cmplx_sort has been deprecated and will be removed in
  SciPy 1.15. A replacement you can use is provided in the deprecation message.

• Values the the argument initial of scipy.integrate.cumulative_trapezoid
  other than 0 and None are now deprecated.

• scipy.stats.rvs_ratio_uniforms is deprecated in favour of
  scipy.stats.sampling.RatioUniforms

• scipy.integrate.quadrature and scipy.integrate.romberg have been
  deprecated due to accuracy issues and interface shortcomings. They will
  be removed in SciPy 1.15. Please use scipy.integrate.quad instead.

• Coinciding with upcoming changes to function signatures (e.g. removal of a
  deprecated keyword), we are deprecating positional use of keyword arguments
  for the affected functions, which will raise an error starting with
  SciPy 1.14. In some cases, this has delayed the originally announced
  removal date, to give time to respond to the second part of the deprecation.
  Affected functions are:

  • linalg.{eigh, eigvalsh, pinv}
  • integrate.simpson
  • signal.{firls, firwin, firwin2, remez}
  • sparse.linalg.{bicg, bicgstab, cg, cgs, gcrotmk, gmres, lgmres, minres, qmr, tfqmr}
  • special.comb
  • stats.kendalltau

• All wavelet functions have been deprecated, as PyWavelets provides suitable
  implementations; affected functions are: signal.{daub, qmf, cascade, morlet, morlet2, ricker, cwt}

• scipy.integrate.trapz, scipy.integrate.cumtrapz, and scipy.integrate.simps have
  been deprecated in favour of scipy.integrate.trapezoid, scipy.integrate.cumulative_trapezoid,
  and scipy.integrate.simpson respectively and will be removed in SciPy 1.14.

• The tol argument of scipy.sparse.linalg.{bcg,bicstab,cg,cgs,gcrotmk,gmres,lgmres,minres,qmr,tfqmr}
  is now deprecated in favour of rtol and will be removed in SciPy 1.14.
  Furthermore, the default value of atol for these functions is due
  to change to 0.0 in SciPy 1.14.

Expired Deprecations

There is an ongoing effort to follow through on long-standing deprecations.
The following previously deprecated features are affected:

• The centered keyword of scipy.stats.qmc.LatinHypercube has been removed.
  Use scrambled=False instead of centered=True.
• scipy.stats.binom_test has been removed in favour of scipy.stats.binomtest.
• In scipy.stats.iqr, the use of scale='raw' has been removed in favour
  of scale=1.

Backwards incompatible changes

Other changes

• The arguments used to compile and link SciPy are now available via
  show_config.

SciPy 1.11.0 Release Notes

SciPy 1.11.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.11.x branch, and on adding new features on the main branch.

This release requires Python 3.9+ and NumPy 1.21.6 or greater.

For running on PyPy, PyPy3 6.0+ is required.

Highlights of this release

• Several scipy.sparse array API improvements, including sparse.sparray, a new
  public base class distinct from the older sparse.spmatrix class,
  proper 64-bit index support, and numerous deprecations paving the way to a
  modern sparse array experience.
• scipy.stats added tools for survival analysis, multiple hypothesis testing,
  sensitivity analysis, and working with censored data.
• A new function was added for quasi-Monte Carlo integration, and linear
  algebra functions det and lu now accept nD-arrays.
• An axes argument was added broadly to ndimage functions, facilitating
  analysis of stacked image data.

New features

scipy.integrate improvements

• Added scipy.integrate.qmc_quad for quasi-Monte Carlo integration.
• For an even number of points, scipy.integrate.simpson now calculates
  a parabolic segment over the last three points which gives improved
  accuracy over the previous implementation.

scipy.cluster improvements

• disjoint_set has a new method subset_size for providing the size
  of a particular subset.

scipy.constants improvements

• The quetta, ronna, ronto, and quecto SI prefixes were added.

scipy.linalg improvements

• scipy.linalg.det is improved and now accepts nD-arrays.
• scipy.linalg.lu is improved and now accepts nD-arrays. With the new
  p_indices switch the output permutation argument can be 1D (n,)
  permutation index instead of the full (n, n) array.

scipy.ndimage improvements

• axes argument was added to rank_filter, percentile_filter,
  median_filter, uniform_filter, minimum_filter,
  maximum_filter, and gaussian_filter, which can be useful for
  processing stacks of image data.

scipy.optimize improvements

• scipy.optimize.linprog now passes unrecognized options directly to HiGHS.
• scipy.optimize.root_scalar now uses Newton's method to be used without
  providing fprime and the secant method to be used without a second
  guess.
• scipy.optimize.lsq_linear now accepts bounds arguments of type
  scipy.optimize.Bounds.
• scipy.optimize.minimize method='cobyla' now supports simple bound
  constraints.
• Users can opt into a new callback interface for most methods of
  scipy.optimize.minimize: If the provided callback callable accepts
  a single keyword argument, intermediate_result, scipy.optimize.minimize
  now passes both the current solution and the optimal value of the objective
  function to the callback as an instance of scipy.optimize.OptimizeResult.
  It also allows the user to terminate optimization by raising a
  StopIteration exception from the callback function.
  scipy.optimize.minimize will return normally, and the latest solution
  information is provided in the result object.
• scipy.optimize.curve_fit now supports an optional nan_policy argument.
• scipy.optimize.shgo now has parallelization with the workers argument,
  symmetry arguments that can improve performance, class-based design to
  improve usability, and generally improved performance.

scipy.signal improvements

• istft has an improved warning message when the NOLA condition fails.

scipy.sparse improvements

• A new public base class scipy.sparse.sparray was introduced, allowing further
  extension of the sparse array API (such as the support for 1-dimensional
  sparse arrays) without breaking backwards compatibility.
  isinstance(x, scipy.sparse.sparray) to select the new sparse array classes,
  while isinstance(x, scipy.sparse.spmatrix) selects only the old sparse
  matrix classes.
• Division of sparse arrays by a dense array now returns sparse arrays.
• scipy.sparse.isspmatrix now only returns True for the sparse matrices instances.
  scipy.sparse.issparse now has to be used instead to check for instances of sparse
  arrays or instances of sparse matrices.
• Sparse arrays constructed with int64 indices will no longer automatically
  downcast to int32.
• The argmin and argmax methods now return the correct result when explicit
  zeros are present.

scipy.sparse.linalg improvements

• dividing LinearOperator by a number now returns a
  _ScaledLinearOperator
• LinearOperator now supports right multiplication by arrays
• lobpcg should be more efficient following removal of an extraneous
  QR decomposition.

scipy.spatial improvements

• Usage of new C++ backend for additional distance metrics, the majority of
  which will see substantial performance improvements, though a few minor
  regressions are known. These are focused on distances between boolean
  arrays.

scipy.special improvements

• The factorial functions factorial, factorial2 and factorialk
  were made consistent in their behavior (in terms of dimensionality,
  errors etc.). Additionally, factorial2 can now handle arrays with
  exact=True, and factorialk can handle arrays.

scipy.stats improvements

New Features

• scipy.stats.sobol_indices, a method to compute Sobol' sensitivity indices.
• scipy.stats.dunnett, which performs Dunnett's test of the means of multiple
  experimental groups against the mean of a control group.
• scipy.stats.ecdf for computing the empirical CDF and complementary
  CDF (survival function / SF) from uncensored or right-censored data. This
  function is also useful for survival analysis / Kaplan-Meier estimation.
• scipy.stats.logrank to compare survival functions underlying samples.
• scipy.stats.false_discovery_control for adjusting p-values to control the
  false discovery rate of multiple hypothesis tests using the
  Benjamini-Hochberg or Benjamini-Yekutieli procedures.
• scipy.stats.CensoredData to represent censored data. It can be used as
  input to the fit method of univariate distributions and to the new
  ecdf function.
• Filliben's goodness of fit test as method='Filliben' of
  scipy.stats.goodness_of_fit.
• scipy.stats.ttest_ind has a new method, confidence_interval for
  computing a confidence interval of the difference between means.
• scipy.stats.MonteCarloMethod, scipy.stats.PermutationMethod, and
  scipy.stats.BootstrapMethod are new classes to configure resampling and/or
  Monte Carlo versions of hypothesis tests. They can currently be used with
  scipy.stats.pearsonr.
