I'll be speaking at @pycon.us 2026!

Come on out to Long Beach California for an excellent #Python community event, and maybe listen to me talk about #OpenSource #SupplyChain #Security from #PyPI perspective

It’s practically constantly on our minds 🥹

🗓️✨ The summit will take place on Friday, May 15, 2026 at PyCon US 2026 in Long Beach.

⏳ Attendance requests and topic proposals close on April 30, 2026 AoE.

Looking forward to another good set of discussions across the Python packaging ecosystem.

🎉📦 The Packaging Summit at PyCon US 2026 is now live.

If you work on Python packaging, maintain packages, support downstream distribution, or have topics that would benefit from focused in-person discussion, please take a look:

To the people at Astral: good luck and all the best. Don’t be strangers.

They’ve done incredible work on problems that have mattered to the Python ecosystem for a long time, while respecting our shared process and community norms. They deserve our thanks for that.

I hope everyone who is worried remembers that communities are more resilient than we sometimes give them credit for. The Astral team is part of our Python community.

Today’s news about OpenAI’s acquisition of Astral can be worrying, or even feel like we may be losing something we’ve come to rely on and trust.

This was a lot of work but I'm so happy we could make it happen as a community. Huge thanks to the steering council and everyone that participated in the discussion!

Standardization of the conda ecosystem | conda.org How the conda ecosystem adopted a new set of voted standards and specifications

The conda steering council recently approved a set of CEPs (conda enhancement proposals) that effectively standardize the conda ecosystem. This is a big milestone worth celebrating! 🎉

If you maintain a Jazzband project, expect an email before PyCon US 2026. django-commons is a great option if you're looking for a new home, they've already taken on several projects and got the governance right from day one.

GitHub's slopocalypse made the open membership model untenable, but the cracks were older than that. I was the only roadie for the entire run and never managed to fix that. The full story, with 10 years of data and some honest reflection:

After more than 10 years, Jazzband is sunsetting.

I started it in 2015 because maintaining Open Source alone was exhausting. The idea was simple: shared access, shared responsibility. It's been an honor to watch it grow.

Applications to Join the PSF Meetup Pro Network Are Back Open Following the introduction of the PSF Community Partner Program, the Python Software Foundation (PSF) is pleased to announce that we have reopened the application for Python Meetup groups to join the PSF’s Meetup Pro Network! We’re very excited to bring back this offering to the Python community after applications were temporarily suspended under the broader PSF Grants Program pause last August. Make sure to check out the PSF’s Meetup Pro Network documentation page for more information on how to apply. Reopening applications for the PSF’s Meetup Pro Network is a small but meaningful step forward for our community support-focused programs. The rest of the PSF Grants Program remains on hold while we work through important considerations, such as what we can responsibly budget and how the program will be structured for long-term sustainability. We look forward to sharing more updates when possible. The PSF welcomes your comments, feedback, and suggestions regarding the reopening of the PSF Meetup Pro Network 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. 

🐍📣 Big news for Python Meetup organizers: We’re excited to share that the PSF Meetup Pro Network is back open for applications! Learn more about the network and how to apply ➡️

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!
