by Hynek Schlawack 12 Oct '21

12 Oct '21

I’m happy to announce the release of structlog 21.2.0! With almost a million downloads per month, structlog is the most popular solution for structured logging in Python. It doesn’t just allow you to log key-value pairs in a structured manner, it also makes it EASIER and FASTER. Check out <https://www.structlog.org/en/stable/why.html> if you’re intrigued but not convinced! Heartfelt thanks go to my generous GitHub sponsors <https://github.com/sponsors/hynek>, companies subscribing on Tidelift <https://tidelift.com/subscription/pkg/pypi-structlog> (currently nobody :( – tell your boss!), and people who bought me a coffee on <https://ko-fi.com/the_hynek>! Support like that makes me work on FOSS on a Saturday afternoon, so please consider supporting me <https://hynek.me/say-thanks/> too! <3 RELEASE HIGHLIGHTS: • Support for for beautiful (and helpful!) exceptions by integrating ConsoleRenderer with rich or better-exceptions. • Helpers to access thread-local and context-local context. • Deeper contextvars support. Full changes: https://github.com/hynek/structlog/releases/tag/21.2.0

[RELEASE] Python 3.11.0a1 is available
by Pablo Galindo Salgado 07 Oct '21

07 Oct '21

Now that we are on a release spree, here you have the first alpha release of Python 3.11: Python 3.11.0a1. Let the testing and validation games begin! https://www.python.org/downloads/release/python-3110a1/ *Major new features of the 3.11 series, compared with 3.10* Python 3.11 is still in development. This release, 3.11.0a1 is the first of six planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2022-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2022-08-01). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.11 are still being planned and written. Among the new major new features and changes so far: - PEP 657 <https://www.python.org/dev/peps/pep-0657/> – Include Fine-Grained Error Locations in Tracebacks - PEP 654 <https://www.python.org/dev/peps/pep-0654/> – PEP 654 – Exception Groups and except* - (Hey, fellow core developer, if a feature you find important is missing from this list, let Pablo know <pablogsal(a)python.org>.) The next pre-release of Python 3.11 will be 3.11.0a2, currently scheduled for 2021-11-02. *And now for something completely different* Zero-point energy is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. As well as atoms and molecules, the empty space of the vacuum has these properties. According to quantum field theory, the universe can be thought of not as isolated particles but as continuous fluctuating fields: matter fields, whose quanta are fermions (i.e., leptons and quarks), and force fields, whose quanta are bosons (e.g., photons and gluons). All these fields have a non zero amount of energy called zero-point energy. Physics currently lacks a full theoretical model for understanding zero-point energy; in particular, the discrepancy between theorized and observed vacuum energy is a source of major contention *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.

by Pablo Galindo Salgado 04 Oct '21

04 Oct '21

On behalf of the Python development community and the Python 3.10 release team, I’m pleased to announce the availability of Python 3.10.0. Python 3.10.0 is the newest major release of the Python programming language, and it contains many new features and optimizations. https://www.python.org/downloads/release/python-3100/ # Major new features of the 3.10 series, compared to 3.9 Among the new major new features and changes so far: * [PEP 623](https://www.python.org/dev/peps/pep-0623/) -- Deprecate and prepare for the removal of the wstr member in PyUnicodeObject. * [PEP 604](https://www.python.org/dev/peps/pep-0604/) -- Allow writing union types as X | Y * [PEP 612](https://www.python.org/dev/peps/pep-0612/) -- Parameter Specification Variables * [PEP 626](https://www.python.org/dev/peps/pep-0626/) -- Precise line numbers for debugging and other tools. * [PEP 618 ](https://www.python.org/dev/peps/pep-0618/) -- Add Optional Length-Checking To zip. * [bpo-12782](https://bugs.python.org/issue12782): Parenthesized context managers are now officially allowed. * [PEP 632 ](https://www.python.org/dev/peps/pep-0632/) -- Deprecate distutils module. * [PEP 613 ](https://www.python.org/dev/peps/pep-0613/) -- Explicit Type Aliases * [PEP 634 ](https://www.python.org/dev/peps/pep-0634/) -- Structural Pattern Matching: Specification * [PEP 635 ](https://www.python.org/dev/peps/pep-0635/) -- Structural Pattern Matching: Motivation and Rationale * [PEP 636 ](https://www.python.org/dev/peps/pep-0636/) -- Structural Pattern Matching: Tutorial * [PEP 644 ](https://www.python.org/dev/peps/pep-0644/) -- Require OpenSSL 1.1.1 or newer * [PEP 624 ](https://www.python.org/dev/peps/pep-0624/) -- Remove Py_UNICODE encoder APIs * [PEP 597 ](https://www.python.org/dev/peps/pep-0597/) -- Add optional EncodingWarning [bpo-38605](https://bugs.python.org/issue38605): `from __future__ import annotations` ([PEP 563](https://www.python.org/dev/peps/pep-0563/)) used to be on this list in previous pre-releases but it has been postponed to Python 3.11 due to some compatibility concerns. You can read the Steering Council communication about it [here]( https://mail.python.org/archives/list/python-dev@python.org/thread/CLVXXPQ2…) to learn more. # More resources * [Changelog](https://docs.python.org/3.10/whatsnew/changelog.html#changelog ) * [Online Documentation](https://docs.python.org/3.10/) * [PEP 619](https://www.python.org/dev/peps/pep-0619/), 3.10 Release Schedule * Report bugs at [https://bugs.python.org](https://bugs.python.org). * [Help fund Python and its community](/psf/donations/). # And now for something completely different For a Schwarzschild black hole (a black hole with no rotation or electromagnetic charge), given a free fall particle starting at the event horizon, the maximum propper time it will experience to fall into (which happens when it falls without angular velocity) the singularity is `π*M` (in [natural units](https://en.wikipedia.org/wiki/Natural_units)), where M is the mass of the black hole. For Sagittarius A* (the black hole at the center of the milky way) this time is approximately 1 minute. Schwarzschild black holes are also unique because they have a space-like singularity at their core, which means that the singularity doesn't happen at a specific point in *space* but happens at a specific point in *time* (the future). This means once you are inside the event horizon you cannot point with your finger towards the direction the singularity is located because the singularity happens in your future: no matter where you move, you will "fall" into it. # We hope you enjoy the new releases!

by Ilia Kurenkov 01 Oct '21

01 Oct '21

We are making our debut on this mailing list with a release that fixes a security vulnerability <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3828>. This release is intended to be a drop-in replacement. It contains the following changes: * deprecate nltk.usage(obj) in favor of help(obj) * resolve ReDoS vulnerability in Corpus Reader * solidify performance tests * improve phone number recognition in tweet tokenizer * refactor CISTEM stemmer for German * identify NLTK Team as the author * replace travis badge with github actions badge * add SECURITY.md Thanks to the following contributors to 3.6.4: Tom Aarsen, Mohaned Mashaly, Dimitri Papadopoulos Orfanos, purificant, Danny Sepler What is NLTK? The acronym stands for "Natural Language ToolKit". NLTK is educational software for those interested in natural language processing, though some have also incorporated it into commercial applications (and its License supports this). A key use case is processing standard datasets using the library's corpus readers, to support ML experiments in other packages. Find out more on http://www.nltk.org/ -- Ilia
