[RELEASE] Python 3.9.0 is now available, and you can already test 3.10.0a1!
by Łukasz Langa 05 Oct '20

05 Oct '20

On behalf of the Python development community and the Python 3.9 release team, I’m pleased to announce the availability of Python 3.9.0. Python 3.9.0 is the newest feature release of the Python language, and it contains many new features and optimizations. You can find Python 3.9.0 here: https://www.python.org/downloads/release/python-390/ <https://www.python.org/downloads/release/python-390/> Most third-party distributors of Python should be making 3.9.0 packages available soon. See the “What’s New in Python 3.9 <https://docs.python.org/release/3.9.0/whatsnew/3.9.html>” document for more information about features included in the 3.9 series. Detailed information about all changes made in 3.9.0 can be found in its change log <https://docs.python.org/release/3.9.0/whatsnew/changelog.html#changelog>. Maintenance releases for the 3.9 series will follow at regular bi-monthly intervals starting in late November of 2020. OK, boring! Where is Python 4? Not so fast! The next release after 3.9 will be 3.10. It will be an incremental improvement over 3.9, just as 3.9 was over 3.8, and so on. In fact, our newest Release Manager, Pablo Galindo Salgado, prepared the first alpha release of what will become 3.10.0 a year from now. You can check it out here: https://www.python.org/downloads/release/python-3100a1/ <https://www.python.org/downloads/release/python-3100a1/> We hope you enjoy the new releases!

Introducing NestedText, a nice alternative to JSON, YAML, TOML
by python＠shalmirane.com 03 Oct '20

03 Oct '20

NestedText is a file format for holding data that is to be entered, edited, or viewed by people. It allows data to be organized into a nested collection of dictionaries, lists, and strings. Similar to YAML, but much simpler. It pairs nicely with voluptuous to create a simple and powerful solution for configuration files. NestedText is a nice alternative to JSON, YAML, and TOML. Documentation: https://nestedtext.org Install: pip install nestedtext Support: https://github.com/KenKundert/nestedtext/issues License: MIT Give it a try. -Ken (nestedtext(a)shalmirane.com) <P><A HREF="https://nestedtext.org">NestedText 1.0</A>A Human Friendly Data Format.

pip 20.2 release, plus changes coming in 20.3
by Sumana Harihareswara 01 Oct '20

01 Oct '20

On behalf of the Python Packaging Authority, I am pleased to announce that we have just released pip 20.2, a new version of pip. You can install it by running python -m pip install --upgrade pip. The highlights for this release are: - The beta of the next-generation dependency resolver is available - Faster installations from wheel files - Improved handling of wheels containing non-ASCII file contents - Faster `pip list` using parallelized network operations - Installed packages now contain metadata about whether they were directly requested by the user (PEP 376’s REQUESTED file) The new dependency resolver is *off by default* because it is *not yet ready for everyday use*. The new dependency resolver is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of constraints files, so some workarounds and workflows may break. Please test it with the `--use-feature=2020-resolver` flag. Please see our guide on how to test and migrate, and how to report issues <https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-res…>. We are preparing to change the default dependency resolution behavior and make the new resolver the default in pip 20.3 (in October 2020). This release also partially optimizes pip’s network usage during installation (as part of a Google Summer of Code project by McSinyx <https://summerofcode.withgoogle.com/projects/#5428041779511296>). Please test it with `pip install --use-feature=2020-resolver --use-feature=fast-deps` and report bugs to the issue tracker <https://github.com/pypa/pip/issues/new?template=bug-report.md>. This functionality is *still experimental* and *not ready for everyday use*. You can find more details (including deprecations and removals) in the changelog <https://pip.pypa.io/en/stable/news/>. As with all pip releases, a significant amount of the work was contributed by pip’s user community. Huge thanks to all who have contributed, whether through code, documentation, issue reports and/or discussion. Your help keeps pip improving, and is hugely appreciated. Specific thanks go to Mozilla (through its Mozilla Open Source Support <https://www.mozilla.org/en-US/moss/> Awards) and to the Chan Zuckerberg Initiative <https://chanzuckerberg.com/eoss/> DAF, an advised fund of Silicon Valley Community Foundation, for their funding that enabled substantial work on the new resolver. -- Sumana Harihareswara pip project manager via contract with PSF Changeset Consulting https://changeset.nyc
