Introducing the PSF Community Partner Program The Python Software Foundation (PSF) is excited to announce the introduction of the PSF Community Partner Program. This new program is designed as an “in-kind” way for us to support Python events and initiatives with non-financial assistance through the use of the PSF logo and name, as well as promotional support via sharing qualified posts on PSF official social media accounts. The PSF looks forward to supporting Python community events and initiatives through this new program!The introduction of the PSF Community Partner Program grew out of our desire to find alternative ways to support the community during the pause of our Grants Program (read more about the resulting process below). Even so, we intend to continue offering this in-kind support program after the Grants Program reopens. Our big picture hope is that, over the long term, some community events and initiatives will continue to partner with the PSF while being financially dependent on sponsors and individual donors alone. The PSF is also working on the future of our Grants Program, including when and how we can reopen it in a way that ensures the program’s long-term sustainability while balancing the needs of the Python community. In light of the truly staggering outpouring of support from our community during the 2025 year-end fundraiser, we are now in a stronger position to reopen the Grants Program and are eager to give back in a thoughtful and sustainable way. More updates to come!As with the rollout of any new program, we anticipate small adjustments will need to be made for processes to flow smoothly and to ensure the program serves the Python community well. The PSF welcomes your comments, feedback, and suggestions regarding the new Community Partner Program on the corresponding Discuss thread. We also invite you to join our upcoming PSF Board or Grants Program Office Hour sessions to talk with the PSF Board and Staff synchronously. If you wish to send your feedback privately, please email grants@python.org. 

Introducing the PSF Community Partner Program! The PSF is very excited to announce this new in-kind offering that expands how we support Python community events and initiatives around the world, now and alongside future community support programs 💝🐍

The PSF continues to feel deeply grateful for the outpouring of support from the Python community before and during our 2025 year-end fundraiser. We put together this thank you video to share our appreciation and joy to be in community with each of you 🐍🫶

Sharded repodata in conda (beta): an order of magnitude faster | conda.org Conda fetches repodata much more quickly. Learn how we did it and who helped along the way.

Congratulations to our friends at Anaconda for shipping CEP-16 (sharded repodata). If you use conda-forge from anaconda.org servers, pixi & rattler-build got magically a lot faster!

conda.org/blog/sharde...

Anaconda.org and conda adopt sharded repodata! 🚀

CEP 16, introduced by @prefix.dev, splits the massive repodata files into per-project shards. This allows clients to only fetch what they need, resulting in significant speedups!

Python Software Foundation News

Please join us in thanking @sovereign.tech for committing to a €86,000 investment to improve the security of CPython and the Python Package Index (PyPI). We're thrilled to partner with them to improve security for all users. Read more on our blog:

PyPI and Shai-Hulud: Staying Secure Amid Emerging Threats - The Python Package Index Blog Shai-Hulud is a great worm, not yet a snake. Attack on npm ecosystem may have implications for PyPI.

There's a nasty #OpenSource #SupplyChain worm going around named Shai-Hulud. It's also capable of exposing some projects' long-lived PyPI API Tokens. Read more on what's happening, and what you can do to protect your projects.

TL,DR: Adopt Trusted Publishing 🔐🚀📦
