Subject: SQLObject 3.7.2
Message-ID: <20190501161839.vdlbkbvvx3clmd2d@phdru.name>

Hello!

I'm pleased to announce version 3.7.2, the second bugfix release of branch
3.7 of SQLObject.


What's new in SQLObject
=======================

Minor features
--------------

* Adapt Postgres exception handling to ``psycopg2`` version ``2.8``:
  in the recent ``psycopg2`` errors are in ``psycopg2.errors`` module.

* Removed RdbhostConnection: David Keeney and rdbhost seem to be unavailable
  since 2017.

For a more complete list, please see the news:
http://sqlobject.org/News.html


What is SQLObject
=================

SQLObject is an object-relational mapper.  Your database tables are described
as classes, and rows are instances of those classes.  SQLObject is meant to be
easy to use and quick to get started with.

SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite,
Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).

Python 2.7 or 3.4+ is required.

Example
=======

Create a simple class that wraps a table::

  >>> from sqlobject import *
  >>>
  >>> sqlhub.processConnection = connectionForURI('sqlite:/:memory:')
  >>>
  >>> class Person(SQLObject):
  ...     fname = StringCol()
  ...     mi = StringCol(length=1, default=None)
  ...     lname = StringCol()
  ...
  >>> Person.createTable()

Use the object::

  >>> p = Person(fname="John", lname="Doe")
  >>> p
  <Person 1 fname='John' mi=None lname='Doe'>
  >>> p.fname
  'John'
  >>> p.mi = 'Q'
  >>> p2 = Person.get(1)
  >>> p2
  <Person 1 fname='John' mi='Q' lname='Doe'>
  >>> p is p2
  True

Queries::

  >>> p3 = Person.selectBy(lname="Doe")[0]
  >>> p3
  <Person 1 fname='John' mi='Q' lname='Doe'>
  >>> pc = Person.select(Person.q.lname=="Doe").count()
  >>> pc
  1

Dear all,

In honor of Star Wars Day, we are releasing a new version of george-lucas, a Python wrapper for a Telnet client that plays an asciitext version of ?A New Hope? in the terminal.

This release includes offline support, which means you can watch Star Wars even if the server which hosts the frames is getting bombarded with requests, because, for example, it is Star Wars Day.

GitHub:?https://github.com/deniederhut/george_lucas

May the Fourth be with you.

Yours,
Dillon

Subject: Pythran 0.9.2 - koailh
Message-ID: <20190505200017.GA11791@sguelton.remote.csb>

Hi folks, and sorry for the double posting if any.

It's my great pleasure to announce the release of Pythran 0.9.2, codenamed koailh.

Pythran is an ahead of time compiler for scientific kernels written in Python. It is
backward-compatible with Python (no language extension) and can take advantage of
OpenMP annotations and automatic SIMD instruction generation.

It's been more than four months since last release, so there's quite a lot of changes.
The detailed changelog is available online:

    https://pythran.readthedocs.io/en/latest/
    
Notable Changes
===============

In addition to bugfixes and new function support, the most significant changes are the
support of a special notation to describe optional argument in Pythran annotations:

    #pythran export foo(int, int?)

This notation is equivalent to:

    #pythran export foo(int)
    #pythran export foo(int, int)
    
This release also introduces a new dependency on the beniget package that provides use-def
chains construction for Python code:

    https://github.com/serge-sans-paille/beniget

A significant memory leak when converting extended slice from pythran to python has been
spoted and fixed.

In total, a great deal of 43 issues have been closed!

    https://github.com/serge-sans-paille/pythran/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed+closed%3A%3E2019-01-20+

Sample Code
===========

As usual, I like to demonstrate Pythran through a small benchmark that used to be unsupported
and now provides a nice x6 speedup (without xsimd) up to (with xsimd, non-strided version) over
Python reference:

    import numpy as np
    #pythran export f_dist(float64[:,:], float64[:,:])
    #pythran export f_dist(float64[::,::], float64[::,::])
    def f_dist(X1, X2):
        return np.sum(np.abs(X1[:, None, :] - X2), axis=-1)

(from https://stackoverflow.com/questions/55854611/efficient-way-of-vectorizing-distance-calculation/)

Download
========

You can retrieve the package through PyPI:

    https://pypi.org/project/pythran/

Download the source on GitHub:

    https://github.com/serge-sans-paille/pythran

Or using the conda package, now available for Windows in addition to Linux and OSX through conda-forge

    https://anaconda.org/conda-forge/pythran

Subject: [RELEASE] Python 3.8.0a4 is now available for testing
Message-ID: <27210321-6B27-4629-9643-2A64F62DA85D@langa.pl>

It's time for the LAST alpha of Python 3.8.0. Go get it here:
https://www.python.org/downloads/release/python-380a4/ <https://www.python.org/downloads/release/python-380a4/>

Python 3.8.0a4 is the fourth and final alpha release of Python 3.8,
the next feature release of Python.  During the alpha phase, Python 3.8
remains under heavy development: additional features will be added
and existing features may be modified or deleted.  Please keep in mind
that this is a preview release and its use is not recommended for
production environments.  The first beta release, 3.8.0b1, is planned
for 2019-05-31.

The release has slipped a week because of me being overwhelmed
with PyCon US this year.  There was also a release blocker and
a breaking change to ElementTree.  Anyway, sorry for the wait!
I moved the planned date of beta1 a few days to make up for it.

If you have a feature you're working on and you'd like to see it in
3.8.0, NOW IS THE TIME TO ACT. Please don't wait until May 30th,
get a proper review and land your change as soon as possible.

Q: Can I get my feature in after that date if I ask nicely?
A: Yes, of course. I will release it in Python 3.9.

Subject: Farewell, Python 3.4
Message-ID: <f8034796-9f54-c779-7697-83a86e583a13@hastings.org>


It's with a note of sadness that I announce the final retirement of 
Python 3.4.? The final release was back in March, but I didn't get 
around to actually closing and deleting the 3.4 branch until this morning.

Python 3.4 introduced many features we all enjoy in modern Python--the 
asyncio, ensurepip, and enum packages, just to name three.? It's a 
release I hope we all remember fondly.

My eternal thanks to all the members of the release team that worked on 
Python 3.4:

    Georg Brandl

    Julien Palard

    Martin von L?wis

    Ned Deily

    Steve Dower

    Terry Reedy

    and all the engineers of the Python infrastructure team.

Special thanks to Benjamin Peterson and Ned Deily, who frequently 
scurried around behind the scenes cleaning up the messes I cluelessly 
left in my wake.

Having closed 3.4, I am now retired as Python 3.4 Release Manager.? I 
regret to inform all of you that you're still stuck with me as Python 
3.5 Release Manager until sometime next year.


My very best wishes,


//arry/

For details see What's New in Wing 7: https://wingware.com/wingide/whatsnew

Wing 7 installs side by side with earlier versions of Wing, so there is 
no need to remove old versions in order to try it. Wing 7 will read and 
convert your old preferences, settings, and projects. Projects should be 
saved to a new
name since earlier versions of Wing cannot read Wing 7 projects.

Subject: CheetahTemplate 3.2.3
Message-ID: <20190510182411.2e34q4swdlkethai@phdru.name>

Hello!

I'm pleased to announce version 3.2.3, the third bugfix release of branch
3.2 of CheetahTemplate3.


What's new in CheetahTemplate3
==============================

Bug fixes:

  - Fixed infinite recursion in ``ImportManager`` on importing
    a builtin module.

Documentation:

  - The site https://cheetahtemplate.org/ is now served with HTTPS.
  - Updated docs regarding fixed tests.

Tests:

  - Removed ``unittest.main()`` calls from tests:
    ``python -m unittest discover -t Cheetah -s Cheetah/Tests -p '[A-Z]*.py'``
    does it.
  - Fixed ``cheetah test`` command.
  - Fixed script ``buildandrun``: copy test templates
    to the ``build/lib`` directory.


What is CheetahTemplate3
========================

Cheetah3 is a free and open source template engine.
It's a fork of the original CheetahTemplate library.

Python 2.7 or 3.4+ is required.


Where is CheetahTemplate3
=========================

Site:
https://cheetahtemplate.org/

Development:
https://github.com/CheetahTemplate3

Download:
https://pypi.org/project/Cheetah3/3.2.3

News and changes:
https://cheetahtemplate.org/news.html

StackOverflow:
https://stackoverflow.com/questions/tagged/cheetah


Example
=======

Below is a simple example of some Cheetah code, as you can see it's practically
Python. You can import, inherit and define methods just like in a regular Python
module, since that's what your Cheetah templates are compiled to :) ::

    #from Cheetah.Template import Template
    #extends Template

    #set $people = [{'name' : 'Tom', 'mood' : 'Happy'}, {'name' : 'Dick',
                            'mood' : 'Sad'}, {'name' : 'Harry', 'mood' : 'Hairy'}]

    <strong>How are you feeling?</strong>
    <ul>
        #for $person in $people
            <li>
                $person['name'] is $person['mood']
            </li>
        #end for
    </ul>

Oleg.

today at 12:00 CEST.

We will have 200 early-bird tickets available when we open up ticket
sales. They offer a discount of up to 50% over the standard rate and
are usually sold out within a few hours. In 2018 early bird tickets
were sold out in just 45 minutes.

Please have your credit cards ready, in case you want to buy
early-bird tickets. We won?t support Paypal payments this year due to
the issues we ran into with their service last year.

For more details on tickets, please see our registration page:

      * https://ep2019.europython.eu/registration/buy-tickets/ *


Guido van Rossum Core Developer Grant
-------------------------------------

For Python Core Developers, we have put a special grant in place,
which will allow core developers to get free tickets to the
conference. We will issue coupon codes for the regular tickets in the
coming days, since we?d like to keep the early-bird tickets for people
who are not eligible for such grants, refunds or discounts.

If you want to sign up, please check our grant page for details on how
to apply:

Subject: EuroPython 2019: Talk Voting is open
Message-ID: <b3328f47-007f-9366-2e40-0b94de9ddfef@europython.eu>

Talk voting is your chance to tell us what you?d like to see at
EuroPython 2019. We will leave talk voting open until:

		   * Friday, May 17 23:59:59 CEST *

In order to vote, please log in to the website and then navigate to
the talk voting page:


	 * https://ep2019.europython.eu/events/talk-voting/ *


How talk voting works
---------------------

The talk voting page lists all submitted proposals, including talks,
trainings and posters. The proposals are sorted in random order.

In order to vote, have a look at the title/abstract and then indicate
your personal interest in attending this session. We have simplified
the voting process and you may choose between these four options:

- must see
- want to see
- maybe
- not interested

The talks you haven?t voted for are marked "no vote". Your votes are
automatically saved to the backend without the need to click on a save
or submit button.

Please note the voting period is a bit shorter this year. We want to
make up some time and release a first selection of accepted proposals
by May 22.

Who can participate ?
---------------------

Any registered attendee of the current EuroPython as well as any
attendee of one of the past EuroPython conferences going back to 2015
can vote. If you have submitted a proposal this year, you are also
eligible to vote.

Talk Selection
--------------

After the talk voting phase, the EuroPython Program Workgroup (WG)
will use the votes to select the talks and build a schedule.

The talk voting is a good and strong indicator what attendees are
interested to see. Submissions are also selected based on editorial
criteria to e.g. increase diversity, giving a chance to less
mainstream topics as well as avoiding too much of the same topic.

In general, the Program WG will try to give as many speakers a chance
to talk as possible. If speakers have submitted multiple talks, the
one with the highest rating will most likely get selected.


Dates and Venues
----------------

EuroPython will be held from July 8-14 2019 in Basel, Switzerland, at
the Congress Center Basel (BCC) for the main conference days (Wed-Fri)
and the FHNW Muttenz for the workshops/trainings/sprints days
(Mon-Tue, Sat-Sun).

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

Hi all,

On behalf of the SciPy development team I'm pleased to announce
the release of SciPy 1.3.0.

Sources and binary wheels can be found at:
https://pypi.org/project/scipy/
and at:
https://github.com/scipy/scipy/releases/tag/v1.3.0

One of a few ways to install this release with pip:

pip install scipy==1.3.0

==========================
SciPy 1.3.0 Release Notes
==========================

SciPy 1.3.0 is the culmination of 5 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been some 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
1.3.x branch, and on adding new features on the master branch.

This release requires Python 3.5+ and NumPy 1.13.3 or greater.

For running on PyPy, PyPy3 6.0+ and NumPy 1.15.0 are required.

Highlights of this release
---------------------------------

- - Three new ``stats`` functions, a rewrite of ``pearsonr``, and an exact
  computation of the Kolmogorov-Smirnov two-sample test
- - A new Cython API for bounded scalar-function root-finders in
`scipy.optimize`
- - Substantial ``CSR`` and ``CSC`` sparse matrix indexing performance
  improvements
- - Added support for interpolation of rotations with continuous angular
  rate and acceleration in ``RotationSpline``


New features
============

`scipy.interpolate` improvements
-------------------------------------------

A new class ``CubicHermiteSpline`` is introduced. It is a piecewise-cubic
interpolator which matches observed values and first derivatives. Existing
cubic interpolators ``CubicSpline``, ``PchipInterpolator`` and
``Akima1DInterpolator`` were made subclasses of ``CubicHermiteSpline``.

`scipy.io` improvements
--------------------------------

For the Attribute-Relation File Format (ARFF) `scipy.io.arff.loadarff`
now supports relational attributes.

`scipy.io.mmread` can now parse Matrix Market format files with empty lines.

`scipy.linalg` improvements
------------------------------------

Added wrappers for ``?syconv`` routines, which convert a symmetric matrix
given by a triangular matrix factorization into two matrices and vice versa.

`scipy.linalg.clarkson_woodruff_transform` now uses an algorithm that
leverages
sparsity. This may provide a 60-90 percent speedup for dense input matrices.
Truly sparse input matrices should also benefit from the improved sketch
algorithm, which now correctly runs in ``O(nnz(A))`` time.

Added new functions to calculate symmetric Fiedler matrices and
Fiedler companion matrices, named `scipy.linalg.fiedler` and
`scipy.linalg.fiedler_companion`, respectively. These may be used
for root finding.

`scipy.ndimage` improvements
----------------------------------------

Gaussian filter performances may improve by an order of magnitude in
some cases, thanks to removal of a dependence on ``np.polynomial``. This
may impact `scipy.ndimage.gaussian_filter` for example.

`scipy.optimize` improvements
----------------------------------------

The `scipy.optimize.brute` minimizer obtained a new keyword ``workers``,
which
can be used to parallelize computation.

A Cython API for bounded scalar-function root-finders in `scipy.optimize`
is available in a new module `scipy.optimize.cython_optimize` via
``cimport``.
This API may be used with ``nogil`` and ``prange`` to loop
over an array of function arguments to solve for an array of roots more
quickly than with pure Python.

``'interior-point'`` is now the default method for ``linprog``, and
``'interior-point'`` now uses SuiteSparse for sparse problems when the
required scikits  (scikit-umfpack and scikit-sparse) are available.
On benchmark problems (gh-10026), execution time reductions by factors of
2-3
were typical. Also, a new ``method='revised simplex'`` has been added.
It is not as fast or robust as ``method='interior-point'``, but it is a
faster,
more robust, and equally accurate substitute for the legacy
``method='simplex'``.

``differential_evolution`` can now use a ``Bounds`` class to specify the
bounds for the optimizing argument of a function.

`scipy.optimize.dual_annealing` performance improvements related to
vectorisation of some internal code.

`scipy.signal` improvements
-------------------------------------

Two additional methods of discretization are now supported by
`scipy.signal.cont2discrete`: ``impulse`` and ``foh``.

`scipy.signal.firls` now uses faster solvers

`scipy.signal.detrend` now has a lower physical memory footprint in some
cases, which may be leveraged using the new ``overwrite_data`` keyword
argument

`scipy.signal.firwin` ``pass_zero`` argument now accepts new string
arguments
that allow specification of the desired filter type: ``'bandpass'``,
``'lowpass'``, ``'highpass'``, and ``'bandstop'``

`scipy.signal.sosfilt` may have improved performance due to lower retention
of the global interpreter lock (GIL) in algorithm

`scipy.sparse` improvements
--------------------------------------

A new keyword was added to ``csgraph.dijsktra`` that
allows users to query the shortest path to ANY of the passed in indices,
as opposed to the shortest path to EVERY passed index.

`scipy.sparse.linalg.lsmr` performance has been improved by roughly 10
percent
on large problems

Improved performance and reduced physical memory footprint of the algorithm
used by `scipy.sparse.linalg.lobpcg`

``CSR`` and ``CSC`` sparse matrix fancy indexing performance has been
improved substantially

`scipy.spatial` improvements
--------------------------------------

`scipy.spatial.ConvexHull` now has a ``good`` attribute that can be used
alongsize the ``QGn`` Qhull options to determine which external facets of a
convex hull are visible from an external query point.

`scipy.spatial.cKDTree.query_ball_point` has been modernized to use some
newer
Cython features, including GIL handling and exception translation. An issue
with ``return_sorted=True`` and scalar queries was fixed, and a new mode
named
``return_length`` was added. ``return_length`` only computes the length of
the
returned indices list instead of allocating the array every time.

`scipy.spatial.transform.RotationSpline` has been added to enable
interpolation
of rotations with continuous angular rates and acceleration

`scipy.stats` improvements
------------------------------------

Added a new function to compute the Epps-Singleton test statistic,
`scipy.stats.epps_singleton_2samp`, which can be applied to continuous and
discrete distributions.

New functions `scipy.stats.median_absolute_deviation` and `scipy.stats.gstd`
(geometric standard deviation) were added. The
`scipy.stats.combine_pvalues`
method now supports ``pearson``,  ``tippett`` and ``mudholkar_george``
pvalue
combination methods.

The `scipy.stats.ortho_group` and `scipy.stats.special_ortho_group`
``rvs(dim)`` functions' algorithms were updated from a ``O(dim^4)``
implementation to a ``O(dim^3)`` which gives large speed improvements
for ``dim>100``.

A rewrite of `scipy.stats.pearsonr` to use a more robust algorithm,
provide meaningful exceptions and warnings on potentially pathological
input,
and fix at least five separate reported issues in the original
implementation.

Improved the precision of ``hypergeom.logcdf`` and ``hypergeom.logsf``.

Added exact computation for Kolmogorov-Smirnov (KS) two-sample test,
replacing
the previously approximate computation for the two-sided test
`stats.ks_2samp`.
Also added a one-sided, two-sample KS test, and a keyword ``alternative``
to
`stats.ks_2samp`.

Backwards incompatible changes
==========================

`scipy.interpolate` changes
------------------------------------

Functions from ``scipy.interpolate`` (``spleval``, ``spline``, ``splmake``,
and ``spltopp``) and functions from ``scipy.misc`` (``bytescale``,
``fromimage``, ``imfilter``, ``imread``, ``imresize``, ``imrotate``,
``imsave``, ``imshow``, ``toimage``) have been removed. The former set has
been deprecated since v0.19.0 and the latter has been deprecated since
v1.0.0.
Similarly, aliases from ``scipy.misc`` (``comb``, ``factorial``,
``factorial2``, ``factorialk``, ``logsumexp``, ``pade``, ``info``,
``source``,
``who``) which have been deprecated since v1.0.0 are removed.
`SciPy documentation for
v1.1.0 <https://docs.scipy.org/doc/scipy-1.1.0/reference/misc.html>`__
can be used to track the new import locations for the relocated functions.

`scipy.linalg` changes
-----------------------------

For ``pinv``, ``pinv2``, and ``pinvh``, the default cutoff values are
changed
for consistency (see the docs for the actual values).

`scipy.optimize` changes
---------------------------------

The default method for ``linprog`` is now ``'interior-point'``. The method's
robustness and speed come at a cost: solutions may not be accurate to
machine precision or correspond with a vertex of the polytope defined
by the constraints. To revert to the original simplex method,
include the argument ``method='simplex'``.

`scipy.stats` changes
----------------------------

Previously, ``ks_2samp(data1, data2)`` would run a two-sided test and
return
the approximated p-value. The new signature, ``ks_2samp(data1, data2,
alternative="two-sided", method="auto")``, still runs the two-sided test by
default but returns the exact p-value for small samples and the approximated
value for large samples. ``method="asymp"`` would be equivalent to the
old version but ``auto`` is the better choice.

Other changes
=============

Our tutorial has been expanded with a new section on global optimizers

There has been a rework of the ``stats.distributions`` tutorials.

`scipy.optimize` now correctly sets the convergence flag of the result to
``CONVERR``, a convergence error, for bounded scalar-function root-finders
if the maximum iterations has been exceeded, ``disp`` is false, and
``full_output`` is true.

`scipy.optimize.curve_fit` no longer fails if ``xdata`` and ``ydata``
dtypes
differ; they are both now automatically cast to ``float64``.

`scipy.ndimage` functions including ``binary_erosion``, ``binary_closing``,
and
``binary_dilation`` now require an integer value for the number of
iterations,
which alleviates a number of reported issues.

Fixed normal approximation in case ``zero_method == "pratt"`` in
`scipy.stats.wilcoxon`.

Fixes for incorrect probabilities, broadcasting issues and thread-safety
related to stats distributions setting member variables inside
``_argcheck()``.

`scipy.optimize.newton` now correctly raises a ``RuntimeError``, when
default
arguments are used, in the case that a derivative of value zero is obtained,
which is a special case of failing to converge.

A draft toolchain roadmap is now available, laying out a compatibility plan
including Python versions, C standards, and NumPy versions.

Subject: ANNOUNCE: wxPython 4.0.5
Message-ID: <469b0d9a-4c4b-ed8e-48fd-4426f84440b8@alldunn.com>


Announcing wxPython 4.0.5
=========================

PyPI:   https://pypi.org/project/wxPython/4.0.5
Extras: https://extras.wxPython.org/wxPython4/extras/
Pip:    ``pip install wxPython==4.0.5``

Changes in this release include the following:


* Added missing HtmlWindow.ScrollToAnchor method, and also a couple
   methods in HtmlCell too. (#1141)

* Added missing setters for the wheel-related properties in
   wx.MouseEvent.  (#1140)

* Updated wxWidgets commit reference, bringing fixes for #1140, #1086
   and #1147.

* Fix the use of the output parameter in HtmlWindow.OnOpeningURL the
   same way it was fixed in
   HtmlWindowInterface.OnHTMLOpeningURL. (#1068)

* Fixed a crashing bug when using a member of a transient
   wx.VisualAttributes object. Also set the attributes to be read-only
   to simplify the fix. (#1198).

* Updated the sip being used in wxPython builds to version 4.19.16.

* Added helper functions to check results of wxWidgets configure
   during the build of wxPython. Currently used to determine if the wx
   webview, glcanvas, and media libraries should be added to the link
   command. (#1138)

* Fixed scrollbar issue with ListCtrlAutoWidthMixin (#1215)

* Fixed file access in the wx.py and wx.tools.pywxrc packages to be
   Python 2 and 3 compatible. (#1193, #1156)

* Fixes for building with Python 3.8 on Linux. (#1227)


Have fun!

Subject: ANNOUNCE wxPython 4.0.6
Message-ID: <764cefb5-f9c7-ad97-edb6-e55520bf7eee@alldunn.com>


Announcing wxPython 4.0.6
=========================

PyPI:   https://pypi.org/project/wxPython/4.0.6
Extras: https://extras.wxPython.org/wxPython4/extras/
Pip:    ``pip install wxPython==4.0.6``

This is a quick-fix release to take care of the following issues:

* Fixed a probably rare, but fatal bug on OSX when calling certain
   overloaded virtual methods with implementations in Python.

* Fixed char pointers in generated stub code to have a valid
   pointer value.

* Reverted the change that loads up install_requires from the
   contents of requirements.txt. Split the requirements.txt file
   into one for install and one for development.



What is wxPython?
-----------------

wxPython is a cross-platform GUI toolkit for the Python programming
language.  It allows Python programmers to create programs with a
robust, highly functional graphical user interface, simply and
easily. It is implemented as a set of Python extension modules that
wrap the GUI components of the popular wxWidgets cross platform
library, which is written in C++. Supported platforms are Microsoft
Windows, Mac OS X and macOS, and Linux or other unix-like systems with
GTK2 or GTK3 libraries. In most cases the native widgets are used on
each platform to provide a 100% native look and feel for the
application.


What is wxPython Phoenix?
-------------------------

wxPython's Project Phoenix is a new from-the-ground-up implementation
of wxPython, created with the intent of making wxPython ?better,
stronger, faster than he was before.? In other words, this new
implementation is focused on improving speed, maintainability and
extensibility of wxPython, as well as removing most of the cruft that
had accumulated over the long life of Classic wxPython.

The project has been in development off and on, mostly behind the
scenes, for many years. For the past few years automated snapshot
builds have been available for those adventurous enough to try it, and
many people eventually started using the snapshots in their projects,
even for production releases.  While there are still some things on
the periphery that need to be completed, the core of the new wxPython
extension modules which wrap the wxWidgets code has been stable for a
long time now.

Due to some things being cleaned up, reorganized, simplified and
dehackified wxPython Phoenix is not completely backwards compatible
with wxPython Classic.  This is intended. In general, however, the API
differences tend to be minor and some applications can use Phoenix
with slight, or even with no modifications.  In some other cases the
correct way to do things was also available in Classic and it's only
the wrong way that has been removed from Phoenix.  For more
information there is a Migration Guide document available at:
https://docs.wxpython.org/MigrationGuide.html

The new wxPython API reference documentation, including all
Python-specific additions and customizations, and docs for the wx.lib
package, is located at: https://docs.wxpython.org/

Hi All,

On behalf of the NumPy team I am pleased to announce the release of NumPy
1.16.4 which contains several fixes for newly reported bugs.  The Python
versions supported in this release are 2.7 and 3.5-3.7.

Downstream developers building this release should use Cython >= 0.29.2
and, if using OpenBLAS, OpenBLAS > v0.3.7.  Wheels for this release can be
downloaded from PyPI <https://pypi.org/project/numpy/1.16.4/>, source
archives and release notes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.16.4>.

If you are installing using pip, you may encounter a problem with older
installed versions of NumPy that pip did not delete becoming mixed with the
current version, resulting in an ``ImportError``. That problem is
particularly
common on Debian derived distributions due to a modified pip.  The fix is
to make sure all previous NumPy versions installed by pip have been
removed. See #12736 <https://github.com/numpy/numpy/issues/12736> for
discussion of the issue.

A total of 10 people contributed to this release.  People with a "+" by
their

Subject: PyCA cryptography 2.7 released
Message-ID: <CABj5TKQuhjzu2EcQ3txMVaXqwyxmgNRhJKA3bo497=YPmiNKOg@mail.gmail.com>

PyCA cryptography 2.7 has been released to PyPI. cryptography includes both
high level recipes and low level interfaces to common cryptographic
algorithms such as symmetric ciphers, asymmetric algorithms, message
digests, X509, key derivation functions, and much more. We support Python
2.7, Python 3.4+, and PyPy.

Changelog (https://cryptography.io/en/latest/changelog/#v2-7):
* Updated Windows, macOS, and manylinux1 wheels to be compiled with OpenSSL
1.1.1c.
* BACKWARDS INCOMPATIBLE: We no longer distribute 32-bit manylinux1 wheels.
Continuing to produce them was a maintenance burden.
* BACKWARDS INCOMPATIBLE: Removed the
cryptography.hazmat.primitives.mac.MACContext interface. The CMAC and HMAC
APIs have not changed, but they are no longer registered as MACContext
instances.
* Removed support for running our tests with setup.py test. Users
interested in running our tests can continue to follow the directions in
our development documentation.
* Add support for Poly1305 when using OpenSSL 1.1.1 or newer.
* Support serialization with Encoding.OpenSSH and PublicFormat.OpenSSH in
Ed25519PublicKey.public_bytes .
* Correctly allow passing a SubjectKeyIdentifier to
from_issuer_subject_key_identifier() and deprecate passing an Extension
object. The documentation always required SubjectKeyIdentifier but the
implementation previously required an Extension.
