Subject: [RELEASE] Python 2.7.15
Message-ID: <1525147795.1134689.1356448000.51663AA1@webmail.messagingengine.com>
Greetings,
I'm pleased to announce the immediate availability of Python 2.7.15, the latest bug fix release in the senescent Python 2.7 series.
Source and binary downloads may be found on python.org:
https://www.python.org/downloads/release/python-2715/
Bugs should be reported to https://bugs.python.org/
The source tarball contains a complete changelog in the Misc/NEWS file. The only change since the release candidate is a fix for undefined C behavior that newer compilers (including GCC 8) have started to exploit.
Users of the macOS binaries should note that all python.org macOS installers now ship with a builtin copy of OpenSSL. Additionally, there is a new additional installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. See the installer README for more information.
Happy May,
Benjamin

Subject: ANN: NumExpr 2.6.5
Message-ID:
==========================
Announcing Numexpr 2.6.5
==========================
Hi everyone,
This is primarily an incremental performance improvement release,
especially
with regards to improving import times of downstream packages (e.g.
`pandas`, `tables`, `sympy`). Import times have been reduced from ~300 ms
to ~100 ms through removing a `pkg_resources` import and making the
`cpuinfo`
import lazy.
The maximum number of threads is now set at import-time, similar to
`numba`, by
setting an environment variable 'NUMEXPR_MAX_THREADS'. The runtime number
of threads can still be reduced by calling `numexpr.set_num_threads(N)`.
DEPRECATION WARNING: The variable `numexpr.is_cpu_amd_intel` has been set
to a
dummy value of `False`. This variable may be removed in the future.
Project documentation is available at:
http://numexpr.readthedocs.io/
Changes from 2.6.4 to 2.6.5
---------------------------
- The maximum thread count can now be set at import-time by setting the
environment variable 'NUMEXPR_MAX_THREADS'. The default number of
max threads was lowered from 4096 (which was deemed excessive) to 64.
- A number of imports were removed (pkg_resources) or made lazy (cpuinfo)
in
order to speed load-times for downstream packages (such as `pandas`,
`sympy`,
and `tables`). Import time has dropped from about 330 ms to 90 ms. Thanks
to
Jason Sachs for pointing out the source of the slow-down.
- Thanks to Alvaro Lopez Ortega for updates to benchmarks to be compatible
with
Python 3.
- Travis and AppVeyor now fail if the test module fails or errors.
- Thanks to Mahdi Ben Jelloul for a patch that removed a bug where
constants
in `where` calls would raise a ValueError.
- Fixed a bug whereby all-constant power operations would lead to infinite
recursion.

Message-ID: <82F6CAB9-4144-4937-B73B-914AD6518173@python.org>
Python 3.7.0b4 is the final beta preview of Python 3.7, the next feature
release of Python. Beta releases are intended to give you the
opportunity to test new features and bug fixes and to prepare your
projects to support the new feature release. We strongly encourage you
to test your projects with 3.7 during the beta phase and report issues
found to bugs.python.org as soon as possible. While the release is
feature complete entering the beta phase, it is possible that features
may be modified or, in rare cases, deleted up until the start of the
release candidate phase. Please keep in mind that this is a preview
release and its use is not recommended for production environments.
Attention macOS users: there is now a new installer variant for macOS
10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant is
expected to become the default version when 3.7.0 releases. Check it out!
The next preview release will be the release candidate and is planned
for 2018-05-21 followed by the official release of 3.7.0, planned for
2018-06-15. You can find Python 3.7.0b4 and more information here:

-----BEGIN PGP SIGNED MESSAGE-----

Hi all,
On behalf of the SciPy development team I'm pleased to announce the
SciPy 1.1.0 release.
Sources and binary wheels can be found at
https://pypi.python.org/pypi/scipy
and at https://github.com/scipy/scipy/releases/tag/v1.1.0.
To install with pip:
pip install scipy==1.1.0
Thanks to everyone who contributed to this release!
=========================
SciPy 1.1.0 Release Notes
=========================
SciPy 1.1.0 is the culmination of 7 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
1.1.x branch, and on adding new features on the master branch.
This release requires Python 2.7 or 3.4+ and NumPy 1.8.2 or greater.
This release has improved but not necessarily 100% compatibility with
the `PyPy `__ Python implementation. For running on
PyPy, PyPy 6.0+ and Numpy 1.15.0+ are required.
New features
============
`scipy.integrate` improvements
- ------------------------------
The argument ``tfirst`` has been added to the function
`scipy.integrate.odeint`. This allows odeint to use the same user
functions as `scipy.integrate.solve_ivp` and `scipy.integrate.ode` without
the need for wrapping them in a function that swaps the first two
arguments.
Error messages from ``quad()`` are now clearer.
`scipy.linalg` improvements
- ---------------------------
The function `scipy.linalg.ldl` has been added for factorization of
indefinite symmetric/hermitian matrices into triangular and block
diagonal matrices.
Python wrappers for LAPACK ``sygst``, ``hegst`` added in
`scipy.linalg.lapack`.
Added `scipy.linalg.null_space`, `scipy.linalg.cdf2rdf`,
`scipy.linalg.rsf2csf`.
`scipy.misc` improvements
- -------------------------
An electrocardiogram has been added as an example dataset for a
one-dimensional signal. It can be accessed through
`scipy.misc.electrocardiogram`.
`scipy.ndimage` improvements
- ----------------------------
The routines `scipy.ndimage.binary_opening`, and
`scipy.ndimage.binary_closing` now support masks and different border
values.
`scipy.optimize` improvements
- -----------------------------
The method ``trust-constr`` has been added to
`scipy.optimize.minimize`. The method switches between two
implementations depending on the problem definition. For equality
constrained problems it is an implementation of a trust-region
sequential quadratic programming solver and, when inequality constraints
are imposed, it switches to a trust-region interior point method. Both
methods are appropriate for large scale problems. Quasi-Newton options
BFGS and SR1 were implemented and can be used to approximate second
order derivatives for this new method. Also, finite-differences can be
used to approximate either first-order or second-order derivatives.
Random-to-Best/1/bin and Random-to-Best/1/exp mutation strategies were
added to `scipy.optimize.differential_evolution` as ``randtobest1bin``
and ``randtobest1exp``, respectively. Note: These names were already in
use but implemented a different mutation strategy. See `Backwards
incompatible changes <#backwards-incompatible-changes>`__, below. The
``init`` keyword for the `scipy.optimize.differential_evolution`
function can now accept an array. This array allows the user to specify
the entire population.
Add an ``adaptive`` option to Nelder-Mead to use step parameters adapted
to the dimensionality of the problem.
Minor improvements in `scipy.optimize.basinhopping`.
`scipy.signal` improvements
- ---------------------------
Three new functions for peak finding in one-dimensional arrays were
added. `scipy.signal.find_peaks` searches for peaks (local maxima) based
on simple value comparison of neighbouring samples and returns those
peaks whose properties match optionally specified conditions for their
height, prominence, width, threshold and distance to each other.
`scipy.signal.peak_prominences` and `scipy.signal.peak_widths` can directly
calculate the prominences or widths of known peaks.
Added ZPK versions of frequency transformations:
`scipy.signal.bilinear_zpk`, `scipy.signal.lp2bp_zpk`,
`scipy.signal.lp2bs_zpk`, `scipy.signal.lp2hp_zpk`,
`scipy.signal.lp2lp_zpk`.
Added `scipy.signal.windows.dpss`,
`scipy.signal.windows.general_cosine` and
`scipy.signal.windows.general_hamming`.
`scipy.sparse` improvements
- ---------------------------
Previously, the ``reshape`` method only worked on
`scipy.sparse.lil_matrix`, and in-place reshaping did not work on any
matrices. Both operations are now implemented for all matrices. Handling
of shapes has been made consistent with ``numpy.matrix`` throughout the
`scipy.sparse` module (shape can be a tuple or splatted, negative
number acts as placeholder, padding and unpadding dimensions of size 1
to ensure length-2 shape).
`scipy.special` improvements
- ----------------------------
Added Owen?s T function as `scipy.special.owens_t`.
Accuracy improvements in ``chndtr``, ``digamma``, ``gammaincinv``,
``lambertw``, ``zetac``.
`scipy.stats` improvements
- --------------------------
The Moyal distribution has been added as `scipy.stats.moyal`.
Added the normal inverse Gaussian distribution as
`scipy.stats.norminvgauss`.
Deprecated features
===================
The iterative linear equation solvers in `scipy.sparse.linalg` had a
sub-optimal way of how absolute tolerance is considered. The default
behavior will be changed in a future Scipy release to a more standard
and less surprising one. To silence deprecation warnings, set the
``atol=`` parameter explicitly.
`scipy.signal.windows.slepian` is deprecated, replaced by
`scipy.signal.windows.dpss`.
The window functions in `scipy.signal` are now available in
`scipy.signal.windows`. They will remain also available in the old
location in the `scipy.signal` namespace in future Scipy versions.
However, importing them from `scipy.signal.windows` is preferred, and
new window functions will be added only there.
Indexing sparse matrices with floating-point numbers instead of integers
is deprecated.
The function `scipy.stats.itemfreq` is deprecated.
Backwards incompatible changes
==============================
Previously, `scipy.linalg.orth` used a singular value cutoff value
appropriate for double precision numbers also for single-precision
input. The cutoff value is now tunable, and the default has been changed
to depend on the input data precision.
In previous versions of Scipy, the ``randtobest1bin`` and
``randtobest1exp`` mutation strategies in
`scipy.optimize.differential_evolution` were actually implemented using
the Current-to-Best/1/bin and Current-to-Best/1/exp strategies,
respectively. These strategies were renamed to ``currenttobest1bin`` and
``currenttobest1exp`` and the implementations of ``randtobest1bin`` and
``randtobest1exp`` strategies were corrected.
Functions in the ndimage module now always return their output array.
Before this most functions only returned the output array if it had been
allocated by the function, and would return ``None`` if it had been
provided by the user.
Distance metrics in `scipy.spatial.distance` now require non-negative
weights.
`scipy.special.loggamma` returns now real-valued result when the input
is real-valued.
Other changes
=============
When building on Linux with GNU compilers, the ``.so`` Python extension
files now hide all symbols except those required by Python, which can
avoid problems when embedding the Python interpreter.
