NumPy 1.11.0 Release Notes

This release supports Python 2.6 - 2.7 and 3.2 - 3.5 and contains a number of \ 
enhancements and improvements. Note also the build system changes listed below \ 
as they may have subtle effects.

No Windows (TM) binaries are provided for this release due to a broken \ 
toolchain. One of the providers of Python packages for Windows (TM) is your best \ 
bet.
Highlights

Details of these improvements can be found below.

    The datetime64 type is now timezone naive.
    A dtype parameter has been added to randint.
    Improved detection of two arrays possibly sharing memory.
    Automatic bin size estimation for np.histogram.
    Speed optimization of A @ A.T and dot(A, A.T).
    New function np.moveaxis for reordering array axes.

Build System Changes

    Numpy now uses setuptools for its builds instead of plain distutils. This \ 
fixes usage of install_requires='numpy' in the setup.py files of projects that \ 
depend on Numpy (see gh-6551). It potentially affects the way that build/install \ 
methods for Numpy itself behave though. Please report any unexpected behavior on \ 
the Numpy issue tracker.
    Bento build support and related files have been removed.
    Single file build support and related files have been removed.

Future Changes

The following changes are scheduled for Numpy 1.12.0.

    Support for Python 2.6, 3.2, and 3.3 will be dropped.
    Relaxed stride checking will become the default. See the 1.8.0 release notes \ 
for a more extended discussion of what this change implies.
    The behavior of the datetime64 "not a time" (NaT) value will be \ 
changed to match that of floating point "not a number" (NaN) values: \ 
all comparisons involving NaT will return False, except for NaT != NaT which \ 
will return True.
    Indexing with floats will raise IndexError, e.g., a[0, 0.0].
    Indexing with non-integer array_like will raise IndexError, e.g., a['1', '2']
    Indexing with multiple ellipsis will raise IndexError, e.g., a[..., ...].
    Non-integers used as index values will raise TypeError, e.g., in reshape, \ 
take, and specifying reduce axis.

In a future release the following changes will be made.

    The rand function exposed in numpy.testing will be removed. That function is \ 
left over from early Numpy and was implemented using the Python random module. \ 
The random number generators from numpy.random should be used instead.
    The ndarray.view method will only allow c_contiguous arrays to be viewed \ 
using a dtype of different size causing the last dimension to change. That \ 
differs from the current behavior where arrays that are f_contiguous but not \ 
c_contiguous can be viewed as a dtype type of different size causing the first \ 
dimension to change.
    Slicing a MaskedArray will return views of both data and mask. Currently the \ 
mask is copy-on-write and changes to the mask in the slice do not propagate to \ 
the original mask. See the FutureWarnings section below for details.

Compatibility notes
datetime64 changes

In prior versions of NumPy the experimental datetime64 type always stored times \ 
in UTC. By default, creating a datetime64 object from a string or printing it \ 
would convert from or to local time:

# old behavior
>>>> np.datetime64('2000-01-01T00:00:00')
numpy.datetime64('2000-01-01T00:00:00-0800')  # note the timezone offset -08:00

A consensus of datetime64 users agreed that this behavior is undesirable and at \ 
odds with how datetime64 is usually used (e.g., by pandas). For most use cases, \ 
a timezone naive datetime type is preferred, similar to the datetime.datetime \ 
type in the Python standard library. Accordingly, datetime64 no longer assumes \ 
that input is in local time, nor does it print local times:

>>>> np.datetime64('2000-01-01T00:00:00')
numpy.datetime64('2000-01-01T00:00:00')

For backwards compatibility, datetime64 still parses timezone offsets, which it \ 
handles by converting to UTC. However, the resulting datetime is timezone naive:

>>> np.datetime64('2000-01-01T00:00:00-08')
DeprecationWarning: parsing timezone aware datetimes is deprecated;
this will raise an error in the future
numpy.datetime64('2000-01-01T08:00:00')

As a corollary to this change, we no longer prohibit casting between datetimes \ 
with date units and datetimes with time units. With timezone naive datetimes, \ 
the rule for casting from dates to times is no longer ambiguous.
linalg.norm return type changes

The return type of the linalg.norm function is now floating point without \ 
exception. Some of the norm types previously returned integers.
polynomial fit changes

The various fit functions in the numpy polynomial package no longer accept \ 
non-integers for degree specification.
np.dot now raises TypeError instead of ValueError

This behaviour mimics that of other functions such as np.inner. If the two \ 
arguments cannot be cast to a common type, it could have raised a TypeError or \ 
ValueError depending on their order. Now, np.dot will now always raise a \ 
TypeError.
FutureWarning to changed behavior

    In np.lib.split an empty array in the result always had dimension (0,) no \ 
matter the dimensions of the array being split. This has been changed so that \ 
the dimensions will be preserved. A FutureWarning for this change has been in \ 
place since Numpy 1.9 but, due to a bug, sometimes no warning was raised and the \ 
dimensions were already preserved.

% and // operators

These operators are implemented with the remainder and floor_divide functions \ 
respectively. Those functions are now based around fmod and are computed \ 
together so as to be compatible with each other and with the Python versions for \ 
float types. The results should be marginally more accurate or outright bug \ 
fixes compared to the previous results, but they may differ significantly in \ 
cases where roundoff makes a difference in the integer returned by floor_divide. \ 
Some corner cases also change, for instance, NaN is always returned for both \ 
functions when the divisor is zero, divmod(1.0, inf) returns (0.0, 1.0) except \ 
on MSVC 2008, and divmod(-1.0, inf) returns (-1.0, inf).
C API

Removed the check_return and inner_loop_selector members of the PyUFuncObject \ 
struct (replacing them with reserved slots to preserve struct layout). These \ 
were never used for anything, so it's unlikely that any third-party code is \ 
using them either, but we mention it here for completeness.
object dtype detection for old-style classes

In python 2, objects which are instances of old-style user-defined classes no \ 
longer automatically count as 'object' type in the dtype-detection handler. \ 
Instead, as in python 3, they may potentially count as sequences, but only if \ 
they define both a __len__ and a __getitem__ method. This fixes a segfault and \ 
inconsistency between python 2 and 3.
New Features

    np.histogram now provides plugin estimators for automatically estimating the \ 
optimal number of bins. Passing one of ['auto', 'fd', 'scott', 'rice', \ 
'sturges'] as the argument to 'bins' results in the corresponding estimator \ 
being used.

    A benchmark suite using Airspeed Velocity has been added, converting the \ 
previous vbench-based one. You can run the suite locally via python runtests.py \ 
--bench. For more details, see benchmarks/README.rst.

    A new function np.shares_memory that can check exactly whether two arrays \ 
have memory overlap is added. np.may_share_memory also now has an option to \ 
spend more effort to reduce false positives.

    SkipTest and KnownFailureException exception classes are exposed in the \ 
numpy.testing namespace. Raise them in a test function to mark the test to be \ 
skipped or mark it as a known failure, respectively.

    f2py.compile has a new extension keyword parameter that allows the fortran \ 
extension to be specified for generated temp files. For instance, the files can \ 
be specifies to be *.f90. The verbose argument is also activated, it was \ 
previously ignored.

    A dtype parameter has been added to np.random.randint Random ndarrays of the \ 
following types can now be generated:
        np.bool,
        np.int8, np.uint8,
        np.int16, np.uint16,
        np.int32, np.uint32,
        np.int64, np.uint64,
        np.int_ ``, ``np.intp

    The specification is by precision rather than by C type. Hence, on some \ 
platforms np.int64 may be a long instead of long long even if the specified \ 
dtype is long long because the two may have the same precision. The resulting \ 
type depends on which C type numpy uses for the given precision. The byteorder \ 
specification is also ignored, the generated arrays are always in native byte \ 
order.

    A new np.moveaxis function allows for moving one or more array axes to a new \ 
position by explicitly providing source and destination axes. This function \ 
should be easier to use than the current rollaxis function as well as providing \ 
more functionality.

    The deg parameter of the various numpy.polynomial fits has been extended to \ 
accept a list of the degrees of the terms to be included in the fit, the \ 
coefficients of all other terms being constrained to zero. The change is \ 
backward compatible, passing a scalar deg will behave as before.

    A divmod function for float types modeled after the Python version has been \ 
added to the npy_math library.

Improvements
np.gradient now supports an axis argument

The axis parameter was added to np.gradient for consistency. It allows to \ 
specify over which axes the gradient is calculated.
np.lexsort now supports arrays with object data-type

The function now internally calls the generic npy_amergesort when the type does \ 
not implement a merge-sort kind of argsort method.
np.ma.core.MaskedArray now supports an order argument

When constructing a new MaskedArray instance, it can be configured with an order \ 
argument analogous to the one when calling np.ndarray. The addition of this \ 
argument allows for the proper processing of an order argument in several \ 
MaskedArray-related utility functions such as np.ma.core.array and \ 
np.ma.core.asarray.
Memory and speed improvements for masked arrays

Creating a masked array with mask=True (resp. mask=False) now uses np.ones \ 
(resp. np.zeros) to create the mask, which is faster and avoid a big memory \ 
peak. Another optimization was done to avoid a memory peak and useless \ 
computations when printing a masked array.
ndarray.tofile now uses fallocate on linux

The function now uses the fallocate system call to reserve sufficient disk space \ 
on file systems that support it.
Optimizations for operations of the form A.T @ A and A @ A.T

Previously, gemm BLAS operations were used for all matrix products. Now, if the \ 
matrix product is between a matrix and its transpose, it will use syrk BLAS \ 
operations for a performance boost. This optimization has been extended to @, \ 
numpy.dot, numpy.inner, and numpy.matmul.

Note: Requires the transposed and non-transposed matrices to share data.
np.testing.assert_warns can now be used as a context manager

This matches the behavior of assert_raises.
Speed improvement for np.random.shuffle

np.random.shuffle is now much faster for 1d ndarrays.
Changes
Pyrex support was removed from numpy.distutils

The method build_src.generate_a_pyrex_source will remain available; it has been \ 
monkeypatched by users to support Cython instead of Pyrex. It's recommended to \ 
switch to a better supported method of build Cython extensions though.
np.broadcast can now be called with a single argument

The resulting object in that case will simply mimic iteration over a single \ 
array. This change obsoletes distinctions like

    if len(x) == 1:
        shape = x[0].shape
    else:
        shape = np.broadcast(*x).shape

Instead, np.broadcast can be used in all cases.
np.trace now respects array subclasses

This behaviour mimics that of other functions such as np.diagonal and ensures, \ 
e.g., that for masked arrays np.trace(ma) and ma.trace() give the same result.
np.dot now raises TypeError instead of ValueError

This behaviour mimics that of other functions such as np.inner. If the two \ 
arguments cannot be cast to a common type, it could have raised a TypeError or \ 
ValueError depending on their order. Now, np.dot will now always raise a \ 
TypeError.
linalg.norm return type changes

The linalg.norm function now does all its computations in floating point and \ 
returns floating results. This change fixes bugs due to integer overflow and the \ 
failure of abs with signed integers of minimum value, e.g., int8(-128). For \ 
consistancy, floats are used even where an integer might work.
Deprecations
Views of arrays in Fortran order

The F_CONTIGUOUS flag was used to signal that views using a dtype that changed \ 
the element size would change the first index. This was always problematical for \ 
arrays that were both F_CONTIGUOUS and C_CONTIGUOUS because C_CONTIGUOUS took \ 
precedence. Relaxed stride checking results in more such dual contiguous arrays \ 
and breaks some existing code as a result. Note that this also affects changing \ 
the dtype by assigning to the dtype attribute of an array. The aim of this \ 
deprecation is to restrict views to C_CONTIGUOUS arrays at some future time. A \ 
work around that is backward compatible is to use a.T.view(...).T instead. A \ 
parameter may also be added to the view method to explicitly ask for Fortran \ 
order views, but that will not be backward compatible.
Invalid arguments for array ordering

It is currently possible to pass in arguments for the order parameter in methods \ 
like array.flatten or array.ravel that were not one of the following: 'C', 'F', \ 
'A', 'K' (note that all of these possible values are both unicode and case \ 
insensitive). Such behavior will not be allowed in future releases.
Random number generator in the testing namespace

The Python standard library random number generator was previously exposed in \ 
the testing namespace as testing.rand. Using this generator is not recommended \ 
and it will be removed in a future release. Use generators from numpy.random \ 
namespace instead.
Random integer generation on a closed interval

In accordance with the Python C API, which gives preference to the half-open \ 
interval over the closed one, np.random.random_integers is being deprecated in \ 
favor of calling np.random.randint, which has been enhanced with the dtype \ 
parameter as described under "New Features". However, \ 
np.random.random_integers will not be removed anytime soon.
FutureWarnings
Assigning to slices/views of MaskedArray

Currently a slice of a masked array contains a view of the original data and a \ 
copy-on-write view of the mask. Consequently, any changes to the slice's mask \ 
will result in a copy of the original mask being made and that new mask being \ 
changed rather than the original. For example, if we make a slice of the \ 
original like so, view = original[:], then modifications to the data in one \ 
array will affect the data of the other but, because the mask will be copied \ 
during assignment operations, changes to the mask will remain local. A similar \ 
situation occurs when explicitly constructing a masked array using \ 
MaskedArray(data, mask), the returned array will contain a view of data but the \ 
mask will be a copy-on-write view of mask.

In the future, these cases will be normalized so that the data and mask arrays \ 
are treated the same way and modifications to either will propagate between \ 
views. In 1.11, numpy will issue a MaskedArrayFutureWarning warning whenever \ 
user code modifies the mask of a view that in the future may cause values to \ 
propagate back to the original. To silence these warnings and make your code \ 
robust against the upcoming changes, you have two options: if you want to keep \ 
the current behavior, call masked_view.unshare_mask() before modifying the mask. \ 
If you want to get the future behavior early, use masked_view._sharedmask = \ 
False. However, note that setting the _sharedmask attribute will break following \ 
explicit calls to masked_view.unshare_mask().

NumPy 1.10.4 Release Notes

This release is a bugfix source release motivated by a segfault regression. No \ 
windows binaries are provided for this release, as there appear to be bugs in \ 
the toolchain we use to generate those files. Hopefully that problem will be \ 
fixed for the next release. In the meantime, we suggest using one of the \ 
providers of windows binaries.
Compatibility notes

    The trace function now calls the trace method on subclasses of ndarray, \ 
except for matrix, for which the current behavior is preserved. This is to help \ 
with the units package of AstroPy and hopefully will not cause problems.

NumPy 1.10.3 Release Notes

N/A this release did not happen due to various screwups involving PyPi.

NumPy 1.10.2 Release Notes

This release deals with a number of bugs that turned up in 1.10.1 and adds \ 
various build and release improvements.

Numpy 1.10.1 supports Python 2.6 - 2.7 and 3.2 - 3.5.
Compatibility notes
Relaxed stride checking is no longer the default

There were back compatibility problems involving views changing the dtype of \ 
multidimensional Fortran arrays that need to be dealt with over a longer \ 
timeframe.
Fix swig bug in numpy.i

Relaxed stride checking revealed a bug in array_is_fortran(a), that was using \ 
PyArray_ISFORTRAN to check for Fortran contiguity instead of \ 
PyArray_IS_F_CONTIGUOUS. You may want to regenerate swigged files using the \ 
updated numpy.i
Deprecate views changing dimensions in fortran order

This deprecates assignment of a new descriptor to the dtype attribute of a \ 
non-C-contiguous array if it result in changing the shape. This effectively bars \ 
viewing a multidimensional Fortran array using a dtype that changes the element \ 
size along the first axis.

The reason for the deprecation is that, when relaxed strides checking is \ 
enabled, arrays that are both C and Fortran contiguous are always treated as C \ 
contiguous which breaks some code that depended the two being mutually exclusive \ 
for non-scalar arrays of ndim > 1. This deprecation prepares the way to \ 
always enable relaxed stride checking.

column.

A fix for np.lib.split was reverted because it resulted in "fixing" \ 
behavior that will be present in the Numpy 1.11 and that was already present in \ 
Numpy 1.9. See the discussion of the issue at gh-6575 for clarification.

    gh-6576 BUG: Revert gh-6376 to fix split behavior for empty arrays.

Relaxed stride checking was reverted. There were back compatibility problems \ 
involving views changing the dtype of multidimensional Fortran arrays that need \ 
to be dealt with over a longer timeframe.

    gh-6735 MAINT: Make no relaxed stride checking the default for 1.10.

Notes

A bug in the Numpy 1.10.1 release resulted in exceptions being raised for \ 
RuntimeWarning and DeprecationWarning in projects depending on Numpy. That has \ 
been fixed.

NumPy 1.10.1 Release Notes

This release deals with a few build problems that showed up in 1.10.0. Most \ 
users would not have seen these problems. The differences are:

    Compiling with msvc9 or msvc10 for 32 bit Windows now requires SSE2. This \ 
was the easiest fix for what looked to be some miscompiled code when SSE2 was \ 
not used. If you need to compile for 32 bit Windows systems without SSE2 \ 
support, mingw32 should still work.
    Make compiling with VS2008 python2.7 SDK easier
    Change Intel compiler options so that code will also be generated to support \ 
systems without SSE4.2.
    Some _config test functions needed an explicit integer return in order to \ 
avoid the openSUSE rpmlinter erring out.
    We ran into a problem with pipy not allowing reuse of filenames and a \ 
resulting proliferation of ..*.postN releases. Not only were the names getting \ 
out of hand, some packages were unable to work with the postN suffix.

Numpy 1.10.1 supports Python 2.6 - 2.7 and 3.2 - 3.5.

NumPy 1.10.0 Release Notes

This release supports Python 2.6 - 2.7 and 3.2 - 3.5.
Highlights

    numpy.distutils now supports parallel compilation via the --parallel/-j \ 
argument passed to setup.py build
    numpy.distutils now supports additional customization via site.cfg to \ 
control compilation parameters, i.e. runtime libraries, extra \ 
linking/compilation flags.
    Addition of np.linalg.multi_dot: compute the dot product of two or more \ 
arrays in a single function call, while automatically selecting the fastest \ 
evaluation order.
    The new function np.stack provides a general interface for joining a \ 
sequence of arrays along a new axis, complementing np.concatenate for joining \ 
along an existing axis.
    Addition of nanprod to the set of nanfunctions.
    Support for the '@' operator in Python 3.5.

Dropped Support

    The _dotblas module has been removed. CBLAS Support is now in Multiarray.
    The testcalcs.py file has been removed.
    The polytemplate.py file has been removed.
    npy_PyFile_Dup and npy_PyFile_DupClose have been removed from npy_3kcompat.h.
    splitcmdline has been removed from numpy/distutils/exec_command.py.
    try_run and get_output have been removed from numpy/distutils/command/config.py
    The a._format attribute is no longer supported for array printing.
    Keywords skiprows and missing removed from np.genfromtxt.
    Keyword old_behavior removed from np.correlate.

Future Changes

    In array comparisons like arr1 == arr2, many corner cases involving strings \ 
or structured dtypes that used to return scalars now issue FutureWarning or \ 
DeprecationWarning, and in the future will be change to either perform \ 
elementwise comparisons or raise an error.
    In np.lib.split an empty array in the result always had dimension (0,) no \ 
matter the dimensions of the array being split. In Numpy 1.11 that behavior will \ 
be changed so that the dimensions will be preserved. A FutureWarning for this \ 
change has been in place since Numpy 1.9 but, due to a bug, sometimes no warning \ 
was raised and the dimensions were already preserved.
    The SafeEval class will be removed in Numpy 1.11.
    The alterdot and restoredot functions will be removed in Numpy 1.11.

See below for more details on these changes.
Compatibility notes
Default casting rule change

Default casting for inplace operations has changed to 'same_kind'. For instance, \ 
if n is an array of integers, and f is an array of floats, then n += f will \ 
result in a TypeError, whereas in previous Numpy versions the floats would be \ 
silently cast to ints. In the unlikely case that the example code is not an \ 
actual bug, it can be updated in a backward compatible way by rewriting it as \ 
np.add(n, f, out=n, casting='unsafe'). The old 'unsafe' default has been \ 
deprecated since Numpy 1.7.
numpy version string

The numpy version string for development builds has been changed from \ 
x.y.z.dev-githash to x.y.z.dev0+githash (note the +) in order to comply with PEP \ 
440.
relaxed stride checking

NPY_RELAXED_STRIDE_CHECKING is now true by default.

UPDATE: In 1.10.2 the default value of NPY_RELAXED_STRIDE_CHECKING was changed \ 
to false for back compatibility reasons. More time is needed before it can be \ 
made the default. As part of the roadmap a deprecation of dimension changing \ 
views of f_contiguous not c_contiguous arrays was also added.
Concatenation of 1d arrays along any but axis=0 raises IndexError

Using axis != 0 has raised a DeprecationWarning since NumPy 1.7, it now raises \ 
an error.
np.ravel, np.diagonal and np.diag now preserve subtypes

There was inconsistent behavior between x.ravel() and np.ravel(x), as well as \ 
between x.diagonal() and np.diagonal(x), with the methods preserving subtypes \ 
while the functions did not. This has been fixed and the functions now behave \ 
like the methods, preserving subtypes except in the case of matrices. Matrices \ 
are special cased for backward compatibility and still return 1-D arrays as \ 
before. If you need to preserve the matrix subtype, use the methods instead of \ 
the functions.
rollaxis and swapaxes always return a view

Previously, a view was returned except when no change was made in the order of \ 
the axes, in which case the input array was returned. A view is now returned in \ 
all cases.
nonzero now returns base ndarrays

Previously, an inconsistency existed between 1-D inputs (returning a base \ 
ndarray) and higher dimensional ones (which preserved subclasses). Behavior has \ 
been unified, and the return will now be a base ndarray. Subclasses can still \ 
override this behavior by providing their own nonzero method.
C API

The changes to swapaxes also apply to the PyArray_SwapAxes C function, which now \ 
returns a view in all cases.

The changes to nonzero also apply to the PyArray_Nonzero C function, which now \ 
returns a base ndarray in all cases.

The dtype structure (PyArray_Descr) has a new member at the end to cache its \ 
hash value. This shouldn't affect any well-written applications.

The change to the concatenation function DeprecationWarning also affects \ 
PyArray_ConcatenateArrays,
recarray field return types

Previously the returned types for recarray fields accessed by attribute and by \ 
index were inconsistent, and fields of string type were returned as chararrays. \ 
Now, fields accessed by either attribute or indexing will return an ndarray for \ 
fields of non-structured type, and a recarray for fields of structured type. \ 
Notably, this affect recarrays containing strings with whitespace, as trailing \ 
whitespace is trimmed from chararrays but kept in ndarrays of string type. Also, \ 
the dtype.type of nested structured fields is now inherited.
recarray views

Viewing an ndarray as a recarray now automatically converts the dtype to \ 
np.record. See new record array documentation. Additionally, viewing a recarray \ 
with a non-structured dtype no longer converts the result's type to ndarray - \ 
the result will remain a recarray.
'out' keyword argument of ufuncs now accepts tuples of arrays

When using the 'out' keyword argument of a ufunc, a tuple of arrays, one per \ 
ufunc output, can be provided. For ufuncs with a single output a single array is \ 
also a valid 'out' keyword argument. Previously a single array could be provided \ 
in the 'out' keyword argument, and it would be used as the first output for \ 
ufuncs with multiple outputs, is deprecated, and will result in a \ 
DeprecationWarning now and an error in the future.
byte-array indices now raises an IndexError

Indexing an ndarray using a byte-string in Python 3 now raises an IndexError \ 
instead of a ValueError.
Masked arrays containing objects with arrays

For such (rare) masked arrays, getting a single masked item no longer returns a \ 
corrupted masked array, but a fully masked version of the item.
Median warns and returns nan when invalid values are encountered

Similar to mean, median and percentile now emits a Runtime warning and returns \ 
NaN in slices where a NaN is present. To compute the median or percentile while \ 
ignoring invalid values use the new nanmedian or nanpercentile functions.
Functions available from numpy.ma.testutils have changed

All functions from numpy.testing were once available from numpy.ma.testutils but \ 
not all of them were redefined to work with masked arrays. Most of those \ 
functions have now been removed from numpy.ma.testutils with a small subset \ 
retained in order to preserve backward compatibility. In the long run this \ 
should help avoid mistaken use of the wrong functions, but it may cause import \ 
problems for some.
New Features
Reading extra flags from site.cfg

Previously customization of compilation of dependency libraries and numpy itself \ 
was only accomblishable via code changes in the distutils package. Now \ 
numpy.distutils reads in the following extra flags from each group of the \ 
site.cfg:

    runtime_library_dirs/rpath, sets runtime library directories to override

        LD_LIBRARY_PATH

    extra_compile_args, add extra flags to the compilation of sources

    extra_link_args, add extra flags when linking libraries

This should, at least partially, complete user customization.
np.cbrt to compute cube root for real floats

np.cbrt wraps the C99 cube root function cbrt. Compared to np.power(x, 1./3.) it \ 
is well defined for negative real floats and a bit faster.
numpy.distutils now allows parallel compilation

By passing --parallel=n or -j n to setup.py build the compilation of extensions \ 
is now performed in n parallel processes. The parallelization is limited to \ 
files within one extension so projects using Cython will not profit because it \ 
builds extensions from single files.
genfromtxt has a new max_rows argument

A max_rows argument has been added to genfromtxt to limit the number of rows \ 
read in a single call. Using this functionality, it is possible to read in \ 
multiple arrays stored in a single file by making repeated calls to the \ 
function.
New function np.broadcast_to for invoking array broadcasting

np.broadcast_to manually broadcasts an array to a given shape according to \ 
numpy's broadcasting rules. The functionality is similar to broadcast_arrays, \ 
which in fact has been rewritten to use broadcast_to internally, but only a \ 
single array is necessary.
New context manager clear_and_catch_warnings for testing warnings

When Python emits a warning, it records that this warning has been emitted in \ 
the module that caused the warning, in a module attribute __warningregistry__. \ 
Once this has happened, it is not possible to emit the warning again, unless you \ 
clear the relevant entry in __warningregistry__. This makes is hard and fragile \ 
to test warnings, because if your test comes after another that has already \ 
caused the warning, you will not be able to emit the warning or test it. The \ 
context manager clear_and_catch_warnings clears warnings from the module \ 
registry on entry and resets them on exit, meaning that warnings can be \ 
re-raised.
cov has new fweights and aweights arguments

The fweights and aweights arguments add new functionality to covariance \ 
calculations by applying two types of weighting to observation vectors. An array \ 
of fweights indicates the number of repeats of each observation vector, and an \ 
array of aweights provides their relative importance or probability.
Support for the '@' operator in Python 3.5+

Python 3.5 adds support for a matrix multiplication operator '@' proposed in \ 
PEP465. Preliminary support for that has been implemented, and an equivalent \ 
function matmul has also been added for testing purposes and use in earlier \ 
Python versions. The function is preliminary and the order and number of its \ 
optional arguments can be expected to change.
New argument norm to fft functions

The default normalization has the direct transforms unscaled and the inverse \ 
transforms are scaled by 1/n . It is possible to obtain unitary transforms by \ 
setting the keyword argument norm to "ortho" (default is None) so that \ 
both direct and inverse transforms will be scaled by 1/\\sqrt{n} .
Improvements
np.digitize using binary search

np.digitize is now implemented in terms of np.searchsorted. This means that a \ 
binary search is used to bin the values, which scales much better for larger \ 
number of bins than the previous linear search. It also removes the requirement \ 
for the input array to be 1-dimensional.
np.poly now casts integer inputs to float

np.poly will now cast 1-dimensional input arrays of integer type to double \ 
precision floating point, to prevent integer overflow when computing the monic \ 
polynomial. It is still possible to obtain higher precision results by passing \ 
in an array of object type, filled e.g. with Python ints.
np.interp can now be used with periodic functions

np.interp now has a new parameter period that supplies the period of the input \ 
data xp. In such case, the input data is properly normalized to the given period \ 
and one end point is added to each extremity of xp in order to close the \ 
previous and the next period cycles, resulting in the correct interpolation \ 
behavior.
np.pad supports more input types for pad_width and constant_values

constant_values parameters now accepts NumPy arrays and float values. NumPy \ 
arrays are supported as input for pad_width, and an exception is raised if its \ 
values are not of integral type.
np.argmax and np.argmin now support an out argument

The out parameter was added to np.argmax and np.argmin for consistency with \ 
ndarray.argmax and ndarray.argmin. The new parameter behaves exactly as it does \ 
in those methods.
More system C99 complex functions detected and used

All of the functions in complex.h are now detected. There are new fallback \ 
implementations of the following functions.

    npy_ctan,
    npy_cacos, npy_casin, npy_catan
    npy_ccosh, npy_csinh, npy_ctanh,
    npy_cacosh, npy_casinh, npy_catanh

As a result of these improvements, there will be some small changes in returned \ 
values, especially for corner cases.
np.loadtxt support for the strings produced by the float.hex method

The strings produced by float.hex look like 0x1.921fb54442d18p+1, so this is not \ 
the hex used to represent unsigned integer types.
np.isclose properly handles minimal values of integer dtypes

In order to properly handle minimal values of integer types, np.isclose will now \ 
cast to the float dtype during comparisons. This aligns its behavior with what \ 
was provided by np.allclose.
np.allclose uses np.isclose internally.

np.allclose now uses np.isclose internally and inherits the ability to compare \ 
NaNs as equal by setting equal_nan=True. Subclasses, such as np.ma.MaskedArray, \ 
are also preserved now.
np.genfromtxt now handles large integers correctly

np.genfromtxt now correctly handles integers larger than 2**31-1 on 32-bit \ 
systems and larger than 2**63-1 on 64-bit systems (it previously crashed with an \ 
OverflowError in these cases). Integers larger than 2**63-1 are converted to \ 
floating-point values.
np.load, np.save have pickle backward compatibility flags

The functions np.load and np.save have additional keyword arguments for \ 
controlling backward compatibility of pickled Python objects. This enables Numpy \ 
on Python 3 to load npy files containing object arrays that were generated on \ 
Python 2.
MaskedArray support for more complicated base classes

Built-in assumptions that the baseclass behaved like a plain array are being \ 
removed. In particular, setting and getting elements and ranges will respect \ 
baseclass overrides of __setitem__ and __getitem__, and arithmetic will respect \ 
overrides of __add__, __sub__, etc.
Changes
dotblas functionality moved to multiarray

The cblas versions of dot, inner, and vdot have been integrated into the \ 
multiarray module. In particular, vdot is now a multiarray function, which it \ 
was not before.
stricter check of gufunc signature compliance

Inputs to generalized universal functions are now more strictly checked against \ 
the function's signature: all core dimensions are now required to be present in \ 
input arrays; core dimensions with the same label must have the exact same size; \ 
and output core dimension's must be specified, either by a same label input core \ 
dimension or by a passed-in output array.
views returned from np.einsum are writeable

Views returned by np.einsum will now be writeable whenever the input array is \ 
writeable.
np.argmin skips NaT values

np.argmin now skips NaT values in datetime64 and timedelta64 arrays, making it \ 
consistent with np.min, np.argmax and np.max.
Deprecations
Array comparisons involving strings or structured dtypes

Normally, comparison operations on arrays perform elementwise comparisons and \ 
return arrays of booleans. But in some corner cases, especially involving \ 
strings are structured dtypes, NumPy has historically returned a scalar instead. \ 
For example:

### Current behaviour

np.arange(2) == "foo"
# -> False

np.arange(2) < "foo"
# -> True on Python 2, error on Python 3

np.ones(2, dtype="i4,i4") == np.ones(2, dtype="i4,i4,i4")
# -> False

Continuing work started in 1.9, in 1.10 these comparisons will now raise \ 
FutureWarning or DeprecationWarning, and in the future they will be modified to \ 
behave more consistently with other comparison operations, e.g.:

### Future behaviour

np.arange(2) == "foo"
# -> array([False, False])

np.arange(2) < "foo"
# -> error, strings and numbers are not orderable

np.ones(2, dtype="i4,i4") == np.ones(2, dtype="i4,i4,i4")
# -> [False, False]

SafeEval

The SafeEval class in numpy/lib/utils.py is deprecated and will be removed in \ 
the next release.
alterdot, restoredot

The alterdot and restoredot functions no longer do anything, and are deprecated.
pkgload, PackageLoader

These ways of loading packages are now deprecated.
bias, ddof arguments to corrcoef

The values for the bias and ddof arguments to the corrcoef function canceled in \ 
the division implied by the correlation coefficient and so had no effect on the \ 
returned values.

We now deprecate these arguments to corrcoef and the masked array version \ 
ma.corrcoef.

Because we are deprecating the bias argument to ma.corrcoef, we also deprecate \ 
the use of the allow_masked argument as a positional argument, as its position \ 
will change with the removal of bias. allow_masked will in due course become a \ 
keyword-only argument.
dtype string representation changes

Since 1.6, creating a dtype object from its string representation, e.g. 'f4', \ 
would issue a deprecation warning if the size did not correspond to an existing \ 
type, and default to creating a dtype of the default size for the type. Starting \ 
with this release, this will now raise a TypeError.

The only exception is object dtypes, where both 'O4' and 'O8' will still issue a \ 
deprecation warning. This platform-dependent representation will raise an error \ 
in the next release.

In preparation for this upcoming change, the string representation of an object \ 
dtype, i.e. np.dtype(object).str, no longer includes the item size, i.e. will \ 
return '|O' instead of '|O4' or '|O8' as before.

NumPy 1.9.0 Release Notes
*************************

This release supports Python 2.6 - 2.7 and 3.2 - 3.4.

Highlights
==========
* Numerous performance improvements in various areas, most notably indexing and
  operations on small arrays are significantly faster.
  Indexing operations now also release the GIL.
* Addition of `nanmedian` and `nanpercentile` rounds out the nanfunction set.

Dropped Support
===============

* The oldnumeric and numarray modules have been removed.
* The doc/pyrex and doc/cython directories have been removed.
* The doc/numpybook directory has been removed.
* The numpy/testing/numpytest.py file has been removed together with
  the importall function it contained.

Future Changes
==============

* The numpy/polynomial/polytemplate.py file will be removed in NumPy 1.10.0.
* Default casting for inplace operations will change to 'same_kind' in
  Numpy 1.10.0. This will certainly break some code that is currently
  ignoring the warning.
* Relaxed stride checking will be the default in 1.10.0
* String version checks will break because, e.g., '1.9' > '1.10' is True. A
  NumpyVersion class has been added that can be used for such comparisons.
* The diagonal and diag functions will return writeable views in 1.10.0
* The `S` and/or `a` dtypes may be changed to represent Python strings
  instead of bytes, in Python 3 these two types are very different.

Compatibility notes
===================

The diagonal and diag functions return readonly views.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In NumPy 1.8, the diagonal and diag functions returned readonly copies, in
NumPy 1.9 they return readonly views, and in 1.10 they will return writeable
views.

Special scalar float values don't cause upcast to double anymore
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In previous numpy versions operations involving floating point scalars
containing special values ``NaN``, ``Inf`` and ``-Inf`` caused the result
type to be at least ``float64``.  As the special values can be represented
in the smallest available floating point type, the upcast is not performed
anymore.

For example the dtype of:

    ``np.array([1.], dtype=np.float32) * float('nan')``

now remains ``float32`` instead of being cast to ``float64``.
Operations involving non-special values have not been changed.

Percentile output changes
~~~~~~~~~~~~~~~~~~~~~~~~~
If given more than one percentile to compute numpy.percentile returns an
array instead of a list. A single percentile still returns a scalar.  The
array is equivalent to converting the list returned in older versions
to an array via ``np.array``.

If the ``overwrite_input`` option is used the input is only partially
instead of fully sorted.

ndarray.tofile exception type
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All ``tofile`` exceptions are now ``IOError``, some were previously
``ValueError``.

Invalid fill value exceptions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two changes to numpy.ma.core._check_fill_value:

* When the fill value is a string and the array type is not one of
  'OSUV', TypeError is raised instead of the default fill value being used.

* When the fill value overflows the array type, TypeError is raised instead
  of OverflowError.

Polynomial Classes no longer derived from PolyBase
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This may cause problems with folks who depended on the polynomial classes
being derived from PolyBase. They are now all derived from the abstract
base class ABCPolyBase. Strictly speaking, there should be a deprecation
involved, but no external code making use of the old baseclass could be
found.

Using numpy.random.binomial may change the RNG state vs. numpy < 1.9
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A bug in one of the algorithms to generate a binomial random variate has
been fixed. This change will likely alter the number of random draws
performed, and hence the sequence location will be different after a
call to distribution.c::rk_binomial_btpe. Any tests which rely on the RNG
being in a known state should be checked and/or updated as a result.

Random seed enforced to be a 32 bit unsigned integer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``np.random.seed`` and ``np.random.RandomState`` now throw a ``ValueError``
if the seed cannot safely be converted to 32 bit unsigned integers.
Applications that now fail can be fixed by masking the higher 32 bit values to
zero: ``seed = seed & 0xFFFFFFFF``. This is what is done silently in older
versions so the random stream remains the same.

Argmin and argmax out argument
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``out`` argument to ``np.argmin`` and ``np.argmax`` and their
equivalent C-API functions is now checked to match the desired output shape
exactly.  If the check fails a ``ValueError`` instead of ``TypeError`` is
raised.

Einsum
~~~~~~
Remove unnecessary broadcasting notation restrictions.
``np.einsum('ijk,j->ijk', A, B)`` can also be written as
``np.einsum('ij...,j->ij...', A, B)`` (ellipsis is no longer required on 'j')

Indexing
~~~~~~~~

The NumPy indexing has seen a complete rewrite in this version. This makes
most advanced integer indexing operations much faster and should have no
other implications.  However some subtle changes and deprecations were
introduced in advanced indexing operations:

* Boolean indexing into scalar arrays will always return a new 1-d array.
  This means that ``array(1)[array(True)]`` gives ``array([1])`` and
  not the original array.

* Advanced indexing into one dimensional arrays used to have
  (undocumented) special handling regarding repeating the value array in
  assignments when the shape of the value array was too small or did not
  match.  Code using this will raise an error. For compatibility you can
  use ``arr.flat[index] = values``, which uses the old code branch.  (for
  example ``a = np.ones(10); a[np.arange(10)] = [1, 2, 3]``)

* The iteration order over advanced indexes used to be always C-order.
  In NumPy 1.9. the iteration order adapts to the inputs and is not
  guaranteed (with the exception of a *single* advanced index which is
  never reversed for compatibility reasons). This means that the result
  is undefined if multiple values are assigned to the same element.  An
  example for this is ``arr[[0, 0], [1, 1]] = [1, 2]``, which may set
  ``arr[0, 1]`` to either 1 or 2.

* Equivalent to the iteration order, the memory layout of the advanced
  indexing result is adapted for faster indexing and cannot be predicted.

* All indexing operations return a view or a copy. No indexing operation
  will return the original array object. (For example ``arr[...]``)

* In the future Boolean array-likes (such as lists of python bools) will
  always be treated as Boolean indexes and Boolean scalars (including
  python ``True``) will be a legal *boolean* index. At this time, this is
  already the case for scalar arrays to allow the general
  ``positive = a[a > 0]`` to work when ``a`` is zero dimensional.

* In NumPy 1.8 it was possible to use ``array(True)`` and
  ``array(False)`` equivalent to 1 and 0 if the result of the operation
  was a scalar.  This will raise an error in NumPy 1.9 and, as noted
  above, treated as a boolean index in the future.

* All non-integer array-likes are deprecated, object arrays of custom
  integer like objects may have to be cast explicitly.

* The error reporting for advanced indexing is more informative, however
  the error type has changed in some cases. (Broadcasting errors of
  indexing arrays are reported as ``IndexError``)

* Indexing with more then one ellipsis (``...``) is deprecated.

Non-integer reduction axis indexes are deprecated
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Non-integer axis indexes to reduction ufuncs like `add.reduce` or `sum` are
deprecated.

``promote_types`` and string dtype
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``promote_types`` function now returns a valid string length when given an
integer or float dtype as one argument and a string dtype as another
argument.  Previously it always returned the input string dtype, even if it
wasn't long enough to store the max integer/float value converted to a
string.

``can_cast`` and string dtype
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``can_cast`` function now returns False in "safe" casting mode for
integer/float dtype and string dtype if the string dtype length is not long
enough to store the max integer/float value converted to a string.
Previously ``can_cast`` in "safe" mode returned True for integer/float
dtype and a string dtype of any length.

astype and string dtype
~~~~~~~~~~~~~~~~~~~~~~~
The ``astype`` method now returns an error if the string dtype to cast to
is not long enough in "safe" casting mode to hold the max value of
integer/float array that is being casted. Previously the casting was
allowed even if the result was truncated.

`npyio.recfromcsv` keyword arguments change
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`npyio.recfromcsv` no longer accepts the undocumented `update` keyword,
which used to override the `dtype` keyword.

The ``doc/swig`` directory moved
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``doc/swig`` directory has been moved to ``tools/swig``.

The ``npy_3kcompat.h`` header changed
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The unused ``simple_capsule_dtor`` function has been removed from
``npy_3kcompat.h``.  Note that this header is not meant to be used outside
of numpy; other projects should be using their own copy of this file when
needed.

Negative indices in C-Api ``sq_item`` and ``sq_ass_item`` sequence methods
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When directly accessing the ``sq_item`` or ``sq_ass_item`` PyObject slots
for item getting, negative indices will not be supported anymore.
``PySequence_GetItem`` and ``PySequence_SetItem`` however fix negative
indices so that they can be used there.

NDIter
~~~~~~
When ``NpyIter_RemoveAxis`` is now called, the iterator range will be reset.

When a multi index is being tracked and an iterator is not buffered, it is
possible to use ``NpyIter_RemoveAxis``. In this case an iterator can shrink
in size. Because the total size of an iterator is limited, the iterator
may be too large before these calls. In this case its size will be set to ``-1``
and an error issued not at construction time but when removing the multi
index, setting the iterator range, or getting the next function.

This has no effect on currently working code, but highlights the necessity
of checking for an error return if these conditions can occur. In most
cases the arrays being iterated are as large as the iterator so that such
a problem cannot occur.

This change was already applied to the 1.8.1 release.

``zeros_like`` for string dtypes now returns empty strings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To match the `zeros` function `zeros_like` now returns an array initialized
with empty strings instead of an array filled with `'0'`.

New Features
============

Percentile supports more interpolation options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``np.percentile`` now has the interpolation keyword argument to specify in
which way points should be interpolated if the percentiles fall between two
values.  See the documentation for the available options.

Generalized axis support for median and percentile
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``np.median`` and ``np.percentile`` now support generalized axis arguments like
ufunc reductions do since 1.7. One can now say axis=(index, index) to pick a
list of axes for the reduction. The ``keepdims`` keyword argument was also
added to allow convenient broadcasting to arrays of the original shape.

Dtype parameter added to ``np.linspace`` and ``np.logspace``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The returned data type from the ``linspace`` and ``logspace`` functions can
now be specified using the dtype parameter.

More general ``np.triu`` and ``np.tril`` broadcasting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For arrays with ``ndim`` exceeding 2, these functions will now apply to the
final two axes instead of raising an exception.

``tobytes`` alias for ``tostring`` method
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``ndarray.tobytes`` and ``MaskedArray.tobytes`` have been added as aliases
for ``tostring`` which exports arrays as ``bytes``. This is more consistent
in Python 3 where ``str`` and ``bytes`` are not the same.

Build system
~~~~~~~~~~~~
Added experimental support for the ppc64le and OpenRISC architecture.

Compatibility to python ``numbers`` module
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All numerical numpy types are now registered with the type hierarchy in
the python ``numbers`` module.

``increasing`` parameter added to ``np.vander``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ordering of the columns of the Vandermonde matrix can be specified with
this new boolean argument.

``unique_counts`` parameter added to ``np.unique``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The number of times each unique item comes up in the input can now be
obtained as an optional return value.

Support for median and percentile in nanfunctions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``np.nanmedian`` and ``np.nanpercentile`` functions behave like
the median and percentile functions except that NaNs are ignored.

NumpyVersion class added
~~~~~~~~~~~~~~~~~~~~~~~~
The class may be imported from numpy.lib and can be used for version
comparison when the numpy version goes to 1.10.devel. For example::

    >>> from numpy.lib import NumpyVersion
    >>> if NumpyVersion(np.__version__) < '1.10.0'):
    ...     print('Wow, that is an old NumPy version!')

Allow saving arrays with large number of named columns
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The numpy storage format 1.0 only allowed the array header to have a total size
of 65535 bytes. This can be exceeded by structured arrays with a large number
of columns. A new format 2.0 has been added which extends the header size to 4
GiB. `np.save` will automatically save in 2.0 format if the data requires it,
else it will always use the more compatible 1.0 format.

Full broadcasting support for ``np.cross``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``np.cross`` now properly broadcasts its two input arrays, even if they
have different number of dimensions. In earlier versions this would result
in either an error being raised, or wrong results computed.

Improvements
============

Better numerical stability for sum in some cases
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Pairwise summation is now used in the sum method, but only along the fast
axis and for groups of the values <= 8192 in length. This should also
improve the accuracy of var and std in some common cases.

Percentile implemented in terms of ``np.partition``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
``np.percentile`` has been implemented in terms of ``np.partition`` which
only partially sorts the data via a selection algorithm. This improves the
time complexity from ``O(nlog(n))`` to ``O(n)``.

Performance improvement for ``np.array``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The performance of converting lists containing arrays to arrays using
``np.array`` has been improved. It is now equivalent in speed to
``np.vstack(list)``.

Performance improvement for ``np.searchsorted``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For the built-in numeric types, ``np.searchsorted`` no longer relies on the
data type's ``compare`` function to perform the search, but is now
implemented by type specific functions. Depending on the size of the
inputs, this can result in performance improvements over 2x.

Optional reduced verbosity for np.distutils
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Set ``numpy.distutils.system_info.system_info.verbosity = 0`` and then
calls to ``numpy.distutils.system_info.get_info('blas_opt')`` will not
print anything on the output. This is mostly for other packages using
numpy.distutils.

Covariance check in ``np.random.multivariate_normal``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A ``RuntimeWarning`` warning is raised when the covariance matrix is not
positive-semidefinite.

Polynomial Classes no longer template based
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The polynomial classes have been refactored to use an abstract base class
rather than a template in order to implement a common interface. This makes
importing the polynomial package faster as the classes do not need to be
compiled on import.

More GIL releases
~~~~~~~~~~~~~~~~~
Several more functions now release the Global Interpreter Lock allowing more
efficient parallization using the ``threading`` module. Most notably the GIL is
now released for fancy indexing, ``np.where`` and the ``random`` module now
uses a per-state lock instead of the GIL.

MaskedArray support for more complicated base classes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Built-in assumptions that the baseclass behaved like a plain array are being
removed. In particalur, ``repr`` and ``str`` should now work more reliably.

C-API
~~~~~

Deprecations
============

Non-integer scalars for sequence repetition
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Using non-integer numpy scalars to repeat python sequences is deprecated.
For example ``np.float_(2) * [1]`` will be an error in the future.

``select`` input deprecations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The integer and empty input to ``select`` is deprecated. In the future only
boolean arrays will be valid conditions and an empty ``condlist`` will be
considered an input error instead of returning the default.

``rank`` function
~~~~~~~~~~~~~~~~~
The ``rank`` function has been deprecated to avoid confusion with
``numpy.linalg.matrix_rank``.

Object array equality comparisons
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In the future object array comparisons both `==` and `np.equal` will not
make use of identity checks anymore. For example:

>>> a = np.array([np.array([1, 2, 3]), 1])
>>> b = np.array([np.array([1, 2, 3]), 1])
>>> a == b

will consistently return False (and in the future an error) even if the array
in `a` and `b` was the same object.

The equality operator `==` will in the future raise errors like `np.equal`
if broadcasting or element comparisons, etc. fails.

Comparison with `arr == None` will in the future do an elementwise comparison
instead of just returning False. Code should be using `arr is None`.

All of these changes will give Deprecation- or FutureWarnings at this time.

C-API
~~~~~

The utility function npy_PyFile_Dup and npy_PyFile_DupClose are broken by the
internal buffering python 3 applies to its file objects.
To fix this two new functions npy_PyFile_Dup2 and npy_PyFile_DupClose2 are
declared in npy_3kcompat.h and the old functions are deprecated.
Due to the fragile nature of these functions it is recommended to instead use
the python API when possible.

This change was already applied to the 1.8.1 release.
