Preventing ZIP parser confusion attacks on Python package installers - The Python Package Index Blog PyPI will begin warning and will later reject wheels that contain differentiable ZIP features or incorrect RECORD files.

The Python Package Index is introducing new restrictions to protect Python package installers and inspectors from ZIP confusion attacks. There is no evidence that this vulnerability has been exploited. Read the blog post for more information:

Unmasking Phantom Dependencies with Software Bill-of-Materials as Ecosystem Neutral Metadata The Python Software Foundation Security Developer-in-Residence, Seth Larson, published a new white paper with Alpha-Omega about the work to solve the "Phantom Dependency" problem. The white paper details the approach, challenges, and insights into the creation and acceptance of PEP 770 and adopting Software Bill-of-Materials (SBOMs) to improve the measurability of Python packages. 

Check out the 'Unmasking Phantom Dependencies with Software Bill-of-Materials as Ecosystem-Neutral Metadata' white paper by PSF Security Developer-in-Residence Seth Larson, focused on improved transparency and security across the #Python ecosystem!

This is an important moment in Python history, and we need a strong PSF to sustain the Python community's rapid growth. Come and run for the PSF Board of Directors to help set the direction. #python #psf

If you have submitted an application and have yet to receive a decision, you will receive an email from us soon. Thank you for your patience and understanding as we navigate this challenging situation.

The PSF has paused our Grants Program Effective August 1st, 2025, the PSF is temporarily pausing our Grants Program after reaching our 2025 grant budget cap earlier than expected. We know how important this program is to many in our community and making this decision was difficult. This is a necessary step to protect both the future of the program and the short- and long-term sustainability of the PSF. (If this moves you immediately to donate to the PSF, we welcome your contributions via our donations page).

The PSF Grants Program has been temporarily paused after hitting our 2025 funding cap early.
It was an extremely difficult but necessary decision to ensure the program and foundation’s near and long term sustainability. Learn more on our blog: pyfound.blogspot.com/2025/08/the-...

Introducing PSF Grants Program Office Hours In October 2023, we acknowledged the situation surrounding DjangoCon Africa and noted our intent to make ongoing improvements to the Grants Program. We also recognize that we are in a new world of hybrid programming since the onset of the pandemic which comes with different funding and cost challenges. One step we are taking to refresh the Grants Program (we’ll be reporting on other steps soon) is to establish PSF Grants Program Office Hours. The office hours will be hosted on the Python Software Foundation Discord once a month at 1-2PM UTC (9AM Eastern) on the third Tuesday of the month. (Check what time that is for you.) We invite the Python community to join in to receive support for Grant-related questions and inquiries! If you have urgent or immediate questions related to the Grants Program, please email grants@pyfound.org.

The July edition of the PSF Grants Program Office Hour is kicking off shortly 🐍📋 9 AM EST, 1 PM UTC. Join us if you have any PSF Grant related questions! #python

The Python Language Summit 2025: Lightning Talks Larry Hastings led a moment of silence to remember former core developer Michael Foord, who passed away earlier this year. Michael was known for many things, including “starting the tradition of having the Language Summit events at PyCon”. You can read the memorial for Michael Foord on discuss.python.org.

The PSF board election: what do I need to know? As the PSF board election approaches, I am sure many of you are keen to get involved. It is a special chance for those of us who have been in the community for a while, and who love it, to help it be better. However, do you know what the Python Software Foundation, and particularly the PSF board members do? Have you ever wondered whether you should run for the board?

#Python #community How well do you know about the work of @thepsf.bsky.social? Have you ever think of running for the board election? Maybe you wanna check out the answers of some of the questions you have here:

The Python Language Summit 2025: What do core developers want from Rust? “This talk is very timely, Rust turns 10 years old tomorrow”. David Hewitt is the maintainer of PyO3, a library that allows Python developers to more easily use Rust within a Python project. “It takes time for languages to be adopted, the test is whether a decade later the language is used”. David noted that Rust had already been mentioned multiple times earlier in the Language Summit, but also in “the Python Software Foundation’s RFI response to the US government about memory safety” regarding creating binary extensions.

The Python Language Summit 2025: Fearless Concurrency Tobias Wrigstad, Matthew Parkinson, and Fridtjof Stoldt attended their first Python Language Summit to talk about some new concurrency concepts with core developers. Their slides have great diagrams, so I recommend checking them out. Tobias delivered the presentation to core developers, opening with a “potentially contentious statement” that “[data races and concurrency bugs] were the future that free-threaded Python programmers would see if free-threading was adopted for Python programs”.

The Python Language Summit 2025: State of Free-Threaded Python “Does it make sense to move to the next phase of PEP 703?”, core developer Matt Page opened his presentation to the Language Summit. Free-Threaded Python has come far since the last Language Summit, where Daniele Parmeggiani presented on free-threaded Python using the then-newly-added “--disable-gil” option.

The Python Language Summit 2025: How can we make Breaking Changes Less Painful? The first talk of the Python Language Summit was delivered by Itamar Oren. Itamar has plenty of experience at Meta deploying massive amounts of Python code to production. Itamar’s presentation focused on how Python core developers might make upgrades to Python versions smoother for users in the face of breaking changes to the language and standard library. Itamar shared that “not all breaking changes are equal” and suggested adopting a taxonomy of breaking changes and how much and when they would affect users.
