Hi all,
On behalf of the SciPy development team I'm pleased to announce
the release of SciPy 1.5.3, which is a bug fix release that includes
Linux ARM64 wheels for the first time.
Sources and binary wheels can be found at:
https://pypi.org/project/scipy/
and at: https://github.com/scipy/scipy/releases/tag/v1.5.3
One of a few ways to install this release with pip:
pip install scipy==1.5.3
==========================
SciPy 1.5.3 Release Notes
==========================
SciPy 1.5.3 is a bug-fix release with no new features
compared to 1.5.2. In particular, Linux ARM64 wheels are now
available and a compatibility issue with XCode 12 has
been fixed.

After a nearly year-long alpha and beta phase, Webware for Python 3.0.0 has been released today.
Here are all the important links:
GitHub: https://github.com/WebwareForPython/w4py3
PyPI: https://pypi.org/project/Webware-for-Python/
Documentation: https://webwareforpython.github.io/w4py3/
List of changes: https://webwareforpython.github.io/w4py3/changes.html
Mirgration guide: https://webwareforpython.github.io/w4py3/migrate.html
The main improvements and changes in Webware for Python 3 are:
- Python 3.6 or newer instead of Python 2
- Standard packaging and installation
- Entry points for Webware plug-ins
- WSGI instead of app server and adapters
- Sphinx/ReadTheDocs for documentation
- GitHub Actions to run improved test suite
The WebKit plug-in has been promoted to the top level and does not exist anymore as a separate plug-in. PSP is still supported.
MiddleKit has become an external plug-in now, available at:
https://github.com/WebwareForPython/w4py3-middlekit
Let me know if there are any pain points, bugs or other problems.
You can use GitHub issues, pull requests or the webware mailing list for feedback and sending bug reports or improvements.

In the last few weeks, we had a close look at the how the situation
around COVID-19 is panning out. Unfortunately, things are not moving in
a direction where we’d feel confident to hold next year’s conference as
an in-person event in Dublin.
EuroPython 2022 in Dublin
-------------------------
After discussion with the venue, we decided to postpone the in-person
conference for another year, to July 11-17 2022 in Dublin, Ireland. We
are currently finalizing the details.
Since going online has proven to work well, we also want to keep the
momentum for EuroPython 2022 and are planning to run the event in a
hybrid version, where both speakers and attendees can optionally join
online.
EuroPython 2021 Online
----------------------
Given the experience with running EuroPython 2020 online this year, we
are sure that EuroPython 2021 will be a success as well.
We will take the experience we’ve gained from this year’s event to
improve the online version next year, simplify some aspects, reactivate
finaid and enable joining it in smaller groups to create a distributed
experience.
We’re still collecting ideas, so if you have any suggestions, we’d love
to hear them. Please write to helpdesk(a)europython.eu.
Help spread the word
--------------------
Please help us spread this message by sharing it on your social
networks as widely as possible. Thank you !

I am delighted to announce the release 2.0.0 of Austin. If you haven't
heard of Austin before, it is an open source frame stack sampler for
CPython, distributed under the GPLv3 license. It can be used to obtain
statistical profiling data out of a running Python application without a
single line of instrumentation. This means that you can start profiling a
Python application straightaway, even while it's running on a production
environment, with minimal impact on performance.
The simplest way of using Austin is by piping its output to FlameGraph
for a quick and detailed representation of the collected samples. The
latest release introduces a memory profiling mode which allows you to
profile memory usage.
Austin is a pure C application that has no other dependencies other than
the C standard library. Its source code is hosted on GitHub at
https://github.com/P403n1x87/austin
The README contains installation and usage details, as well as some
examples of Austin in action. Details on how to contribute to Austin's
development can be found at the bottom of the page.
Austin can be installed easily on the following platforms and from the
following sources:
Linux:
- Snap Store
- Debian repositories
macOS:
- Homebrew
Windows:
- Chocolatey
- Scoop
Austin is also simple to compile from sources as it only depends on the
standard C library, if you don't have access to the above listed sources.
Besides support for Python 3.9, this new release of Austin brings a
considerable performance enhancement that allows it to sample up to 8
times faster than previous versions. But please do read on until the end
to find out about some new tools that take advantage of all the key
features of Austin.
Due to increasing popularity, the sample Python applications that were
included in the main repository have been moved to dedicated projects on
GitHub. The TUI can now be found at
https://github.com/P403n1x87/austin-tui
while Austin Web is now available from
https://github.com/P403n1x87/austin-web
They can both be installed easily from PyPI, but in order to use them the
Austin binary needs to be on the PATH environment variable. These
projects now rely on the austin-python Python package that provides a
Python wrapper around Austin. If you are considering making your own
profiling tool based on Austin, this package can spare you from writing
boilerplate code, so it's worth having a look at it at
https://github.com/P403n1x87/austin-python
The documentation is hosted on RTD at
https://austin-python.readthedocs.io/en/latest/
Finally, I am happy to announce the release of pytest-austin, a plugin
for pytest that allows you to set up performance regression testing by
simply decorating your existing pytest test suite. The plugin launches
Austin to profile your test runs, meaning that no further instrumentation
is required. For more details, check out the project on GitHub
https://github.com/P403n1x87/pytest-austin
Like the other Austin tools, pytest-austin can be installed easily from
PyPI.
You can stay up-to-date with the project's development by following
Austin on Twitter (https://twitter.com/AustinSampler).
All the best,
Gabriele <phoenix1987(a)gmail.com>
<p><a href="https://github.com/P403n1x87/austin">Austin 2.0.0</a> -
frame stack sampler for CPython. (13-Oct-20)</p>
Happy to announce a project I've been working on for some time that's
finally in beta: aiosnow, a MIT licensed Python 3 client library for
interacting with an ITSM cloud service, providing something not too
dissimilar to a database ORM.
I'm sharing this here as the library makes use of Python asyncio, and other
cool features like:
- Asynchronous generators, context managers
- Query condition chaining using Python bitwise operators
- Model Schema system implemented using Marshmallow
- The aiohttp library for working with remote HTTP APIs
It was built with modularity in mind, and is meant to be forked, hacked and
consumed in other projects - commercial or otherwise.
What's in it for me?
I do this for fun, to learn, and to support the asyncio backend of another
project I'm working on, which uses this library at its core.
GitHub page:
https://github.com/rbw/aiosnow
Technical documentation:
https://aiosnow.readthedocs.io/en/latest
Big thanks to the code contributors and donors!

I am happy to announce Guppy 3 3.1.0
Guppy 3 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.
Guppy 3 is a fork of Guppy-PE, created by Sverker Nilsson for Python 2.
This is a major feature release. The main news in this release:
o Python 3.9 support, without subinterpreter support or inter-interpreter
traversal.
o Added .byprod classifier via tracemalloc, and .prod to print tracemalloc
traceback.
o Added .all to print all lines in a MorePrinter buffer.
o Added R_INSET relation for being contained by an unordered set.
