Hello all,
I'm very happy to announce the release of pyo 1.0.4, available for python
3.6,
3.7, 3.8 and 3.9.
Pyo is a Python module written in C to help real-time digital signal
processing
script creation. It provides a complete set of classes to build audio
softwares,
compose algorithmic musics or simply explore audio processing.It is
available for
Windows, macOS and linux. It is released under the LGPL 3 license.
Official website: http://ajaxsoundstudio.com/software/pyo/
pyo's documentation: http://ajaxsoundstudio.com/pyodoc/
Latest sources and bug tracker: https://github.com/belangeo/pyo
Installation:
python -m pip install --user pyo
For all the details and how to uninstall version prior to 1.0.0, see this
page
in the documentation:
http://ajaxsoundstudio.com/pyodoc/download.html
This version focuses on stability more than on adding new features.
Many bugs fixed, unit tests added and each object of the library is now
tested individually to ensure that it does not produce memory leaks.
New features:
- Added a level argument to PyoTableObject.normalize() and
PyoMatrixObject.normalize() methods.
- Added a shape argument to PyoTableObject.fadein() and
PyoTableObject.fadeout() methods.
- Added a div() method to PyoTableObject.
- PyoTableObject get(), put() and copyData() methods can read backward with
negative indices.
- On 64-bit architecture, use long instead of int as PyoObjectTable size.
- Added support for item assigment in PyoObjectBase.
- Scale's exp argument now supports float or PyoObject.
- Replaced all allocation functions with python's memory interface.
Bug Fixes:
- Fixed segmentation fault in PyoMatrixObject.read() method.
- VarPort now updates its increment when the time attribute changes.
- Fixed PadSynthTable crash on Windows.
- Fixed crash when DataTable or NewTable size != len(init).
- Fixed memory allocation in expr's initexpr function (issue #190).
- Fixed FreqShift backward shifting (issue #193).
- TableMorph checks table sizes before interpolating to prevent
segmentation fault.
- Prevent normal order to happen in out() function when scrambling channels.
- Fix bug in isPlaying() returning wrong value when set from out().
- Added rt library to linker on linux (should fix shm_unlink undefined
symbol) (issue #129).
- Fixed array out-of-bound bug in SVF2 object.
- Fixed wx assertion in Scope color rendering.
- Fixed segfault in embedded pyo_end_interpreter function.
- Fixed Select counter type range (now accepts a long long value).
- Removed useless string copy in the Jack backend (fixed issue #221).
- Fixed linux libasound and libjack symlinks (issue #179 and #200).

Per Python ad astra!
After fighting with some release blockers, implementing a bunch of GC
traversal functions, and fixing some pending reference leaks, we finally
have Python 3.10.0 beta 2 ready for you! Thanks to everyone that helped to
unblock the release!
https://www.python.org/downloads/release/python-3100b2/
# This is a beta preview of Python 3.10
Python 3.10 is still in development. 3.10.0b2 is the second 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.
We **strongly encourage** maintainers of third-party Python projects to
**test with 3.10** during the beta phase and report issues found to [the
Python bug tracker](https://bugs.python.org/) as soon as possible. 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 (Monday, 2021-08-02). Our
goal is to have no ABI changes after beta 4 and as few code changes as
possible after 3.10.0rc1, the first release candidate. To achieve that, it
will be **extremely important** to get as much exposure for 3.10 as
possible during the beta phase.
Please keep in mind that this is a preview release and its use is **not**
recommended for production environments.
The next pre-release of Python 3.10 will be 3.10.0b3, currently scheduled
for Thursday, 2021-06-17.
# And now for something completely different
The Ehrenfest paradox concerns the rotation of a "rigid" disc in the theory
of relativity. In its original 1909 formulation as presented by Paul
Ehrenfest in relation to the concept of Born rigidity within special
relativity, it discusses an ideally rigid cylinder that is made to rotate
about its axis of symmetry. The radius R as seen in the laboratory frame is
always perpendicular to its motion and should therefore be equal to its
value R0 when stationary. However, the circumference (2Ï€R) should appear
Lorentz-contracted to a smaller value than at rest. This leads to the
apparent contradiction that R = R0 and R < R0.
# We hope you enjoy those new releases!
Thanks to all of the many volunteers who help make Python Development and
these releases possible! Please consider supporting our efforts by
volunteering yourself or through organization contributions to the Python
Software Foundation.
Regards from very sunny London,
Your friendly release team,

I've recently released version 0.3.2 of distlib on PyPI [1]. For newcomers,
distlib is a library of packaging functionality which is intended to be
usable as the basis for third-party packaging tools.
The main changes in this release are as follows:
* Fixed #139: improved handling of errors related to the test PyPI server.
* Fixed #140: allowed "Obsoletes" in more scenarios, to better handle faulty
 metadata already on PyPI.
* Fixed #141: removed unused regular expression.
* Fixed #143: removed normcase() to avoid some problems on Windows.
* Fixed #146: added entry for SourcelessFileLoader to the finder registry.
* Fixed #147: permission bits are now preserved on POSIX when installing from a wheel.
* Made the generation of scripts more configurable.
* Added support for manylinux wheel tags.
A more detailed change log is available at [2].

mimedecode
WHAT IS IT
Mail users, especially in non-English countries, often find that mail
messages arrived in different formats, with different content types, in
different encodings and charsets. Usually this is good because it allows
us to use appropriate format/encoding/whatever. Sometimes, though, some
unification is desirable. For example, one may want to put mail messages
into an archive, make HTML indices, run search indexer, etc. In such
situations converting messages to text in one character set and skipping
some binary attachments is much desirable.
Here is the solution - mimedecode.
This is a program to decode MIME messages. The program expects one
input file (either on command line or on stdin) which is treated as an
RFC822 message, and decodes to stdout or an output file. If the file is
not an RFC822 message it is just copied to the output one-to-one. If the
file is a simple RFC822 message it is decoded as one part. If it is a
MIME message with multiple parts ("attachments") all parts are decoded.
Decoding can be controlled by command-line options.
Think about said mail archive; for example, its maintainer wants to
put there only texts, convert PDF/Postscript to text, pass HTML and
images decoding base64 to html but leaving images encoded, and ignore
everything else. This is how it could be done:
mimedecode -t application/pdf -t application/postscript -t text/plain -b text/html -B 'image/*' -i '*/*'
Version 3.1.0 (2021-05-23)
Convert mimedecode.docbook to reST. Generate html/man/text
using Sphinx.
Replaced outdated and insecure `mktemp` with `NamedTemporaryFile`.
Python 3.8, 3.9.
