I am please to announce the availability of the "baseline" package.
This tool streamlines creation and maintenance of tests which compare string
output against a baseline. It offers a mechanism to compare a string against
a baselined copy and update the baselined copy to match the new value when a
mismatch occurs. The update process includes a manual step to facilitate a
review of the change before acceptance. The tool uses multi-line string
format
for string baselines to improve readability for human review.

***********
Quick Start
***********
Create an empty baseline with a triple quoted multi-line string. Place
the ending triple quote on a separate line and indent it to the level
you wish the string baseline update to be indented to. Add a compare of
the string being tested to the baseline string. Then save the file as
``fox.py``:
.. code-block:: python
from baseline import Baseline
expected = Baseline("""
""")
test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG."
assert test_string == expected
Run ``fox.py`` and observe that the ``assert`` raises an exception since
the strings are not equal. Because the comparison failed, the tool located
the triple quoted baseline string in the source file and updated it with the
miscompared value. When the interpretter exited, the tool saved the updated
source file but changed the file name to ``fox.update.py``:
.. code-block:: python
from baseline import Baseline
expected = Baseline("""
THE QUICK BROWN FOX
JUMPS
OVER THE LAZY DOG.
""")
test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG."
assert test_string == expected
After reviewing the change with your favorite file differencing tool,
accept the change by either manually overwriting the original file or use
the ``baseline`` command line tool to scan the directory for updated
scripts and accept them:
.. code-block:: shell
$ python -m baseline *
Found updates for:
fox.py
Hit [ENTER] to update, [Ctrl-C] to cancel
fox.update.py -> fox.py
Run ``fox.py`` again and observe the ``assert`` does not raise an exception
nor is a source file update generated. If in the future the test value
changes, the ``assert`` will raise an exception and cause a new source file
update to be generated. Simply repeat the review and acceptance step and you
are back in business!

It's time for the last beta release of Python 3.8. Go find it at:
https://www.python.org/downloads/release/python-380b4/ <https://www.python.org/downloads/release/python-380b4/>
This release is the last of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0c1, the first release candidate, currently scheduled for 2019-09-30.
Call to action
We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker as soon as possible. Please note this is the last beta release, there is not much time left to identify and fix issues before the release of 3.8.0. If you were hesitating trying it out before, now is the time.
While the release is planned to be 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 (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0c1, the release candidate.
To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. That beta phase is coming to an end. Please test now.
Please keep in mind that this is a preview release and its use is not recommended for production environments.
Acknowledgments
Many developers worked hard for the past four weeks to squash remaining bugs, some requiring non-obvious decisions. Many thanks to the most active, namely Raymond Hettinger, Steve Dower, Victor Stinner, Terry Jan Reedy, Serhiy Storchaka, Pablo Galindo Salgado, Tal Einat, Zackery Spytz, Ronald Oussoren, Neil Schemenauer, Inada Naoki, Christian Heimes, and Andrew Svetlov.
3.8.0 would not reach the Last Beta without you. Thank you!

What is cx_Freeze?
cx_Freeze is a set of scripts and modules for freezing Python scripts into
executables, in much the same way that py2exe and py2app do. Unlike these
two tools, cx_Freeze is cross platform and should work on any platform that
Python itself works on. It supports Python 3.5 or higher. For Python 2.7,
use version 5.
More information can be found at the web site:
https://anthony-tuininga.github.io/cx_Freeze
What's new?
cx_Freeze 6.0 adds support for Python 3.7 and makes use of a number of
improvements in Python 3. A lot of small improvements and bug fixes were
made. The full release notes can be read here:
https://cx-freeze.readthedocs.io/en/latest/releasenotes.html#version-6-0-au…
.
I want to thank Marcelo Duarte in particular for his help. Without him this
release would have taken even longer than it already has and contained far
fewer improvements and bug fixes!
To install, use the following command:
python -m pip install cx_Freeze --upgrade
I am happy to announce Guppy-PE 0.1.11
Guppy-PE is a library and programming environment for Python,
currently providing in particular the Heapy subsystem, which supports
object and heap memory sizing, profiling and debugging. It also
includes a prototypical specification language, the Guppy
Specification Language (GSL), which can be used to formally specify
aspects of Python programs and generate tests and documentation from a
common source.
The main news in this release:
Contains notes and check that this package is only for Python2. A version for
Python3 is recommended and is available here:

Hi All,
On behalf of the NumPy team I am pleased to announce that NumPy 1.16.5 has
been released. This release fixes bugs reported against the 1.16.4 release
and backports several enhancements from master that seem appropriate for
the LTS release series that is the last to support Python 2.7.
Downstream developers should use Cython >= 0.29.2 and OpenBLAS >= 3.7 to
avoid wrong results on the Skylake architecture. The NumPy wheels on PyPI
are built from the OpenBLAS development branch in order to avoid those
problems. Wheels for this release can be downloaded from PyPI
<https://pypi.org/project/numpy/1.16.5/>, source archives and release notes
are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.16.5>.

Hi All,
On behalf of the NumPy team I am pleased to announce that NumPy 1.17.1 has
been released. This release contains a number of fixes for bugs reported
against NumPy 1.17.0 along with a few documentation and build
improvements. The Python versions supported are 3.5-3.7, note that Python
2.7 has been dropped. Python 3.8b3 should work with the released source
packages, but there are no future guarantees.
Downstream developers should use Cython >= 0.29.13 for Python 3.8 support
and OpenBLAS >= 3.7 to avoid wrong results on the Skylake architecture. The
NumPy wheels on PyPI are built from the OpenBLAS development branch in
order to avoid those problems. Wheels for this release can be downloaded
from PyPI <https://pypi.org/project/numpy/1.17.1/>, source archives and
release notes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.17.1>.
