YOU DID IT- you helped us raise more than ✨$500,000✨ to support Python for everyone!
This end-of-year fundraiser surpassed our greatest hopes, and we are still reeling from this incredible achievement. You came together to dedicate over half a million dollars to the Python ecosystem and community! Our small fundraising team put in a lot of work, but it truly wouldn’t be possible without the generosity and support from our wonderful community. PSF Board and Staff alike are astonished and deeply committed to making the most of every dollar.
Words and emojis feel inadequate to express our vast appreciation, but we still want to say them:
Thank you!
Thank you, thank you, thank you!
Thanks and thanks and MORE THANKS 🥰🥰🥰🥰
With over 5600 individual contributions (which includes new Supporting Members!), and a community-organized matching campaign, the Python community has shown a level of support that every single one of us should feel proud and excited about! We are more confident than ever that we can accomplish anything together: that's the power of community. As we launch into 2026, we look forward to sharing the concrete steps we will be able to make as a result of your support.
Don't worry if you missed out on being a part of the official year-end fundraising campaign: the PSF acceptsdonations andnew members year round! We welcome you to join in to support Python for everyone any time of year. Every contribution makes an impact 💝 |

Improving security and integrity of Python package archivesThe Security Developer-in-Residence Seth Larsonpublished a new white paper withAlpha-Omega on improving the security and integrity of the archive standards backing Python packages such as ZIP and tar. This white paper follows from multiple vulnerabilities and differential attacks that were reported to common Python package installers and handlers, such as “zipfile”, “tarfile” in use by pip,Poetry, and PyPI, and astral-async-tar in use by uv.
The white paper described the work done to implementcomprehensive protections at the package repository layer (PyPI) to protect all installers, whether vulnerable or not, in coordination with package installer security teams for pip and uv. This work also resolved potential vulnerabilities in handling mismatches between ZIP archive central directories and the Python package “RECORD” file.
Expanding PyPI Security CapabilitiesPyPI has been an innovator with Trusted Publishing, and now has theability to integrate with self-managed GitLab instances for those organizations that prefer to host their own instances. Aphishing-prevention safety guard has been added to the account login process for users with TOTP (or authenticator apps), requiring an email-based confirmation. Using phishing-resistant techniques like WebAuthn are preferred and skip this step.
Sovereign Tech Agency and PSF Security PartnershipThe Sovereign Tech Agency hassponsored two security projects, one improving account security and recovery on the Python Package Index (PyPI) by allowing users to associate accounts with other identity providers, such as GitHub or Gmail. The second project improves the fuzzing harnesses for Python standard library modules for archives following recommendations in therecent white paper on archive integrity. This project uses property-based testing from theHypothesis package along with OSS-Fuzz to ensure better coverage of Python-based archive implementations.
Open Infrastructure is not FreeIn September 2025, the Python Software Foundation (PSF) co-signed theOpen Infrastructure is Not Free: A Joint Statement on Sustainable Stewardship Letter published by theOpen Source Security Foundation (OpenSSF) as a steward of thePython Package Index (PyPI).Our follow up blog post, authored by PSF Director of Infrastructure Ee Durbin, highlights the history and current conditions of PyPI and Python usage, what it takes to operate these services, and our hopes for the future of the infrastructure that underpins these critical services. Check outthe blog post to learn more about how each user and company utilizing PyPI can support its future.
Sustainability starts with Support: PSF on Arm infrastructureSustainable open source depends on sustainable infrastructure– andit isn’t free.Our recent case study with Arm, GitHub, and AWS, highlights how corporate support enables reliable, scalable services for the global Python community. By migrating core services like PyPI and CI workflows to Arm-based AWS Graviton instances and GitHub’s Arm64 runners, the PSF achieved a 25% reduction in compute costs, 40% lower carbon emissions, and improved performance for millions of users. This work, led by PSF infrastructure, CPython developers, and corporate partners underscores how direct investment in open source strengthens the ecosystem we all rely on.
CPython Core Dev SprintIn fall of 2025, Arm’s Cambridge HQ hostedthe largest-ever CPython Core Developer Sprint, bringing 35 core devs and 13 guests together for a week of deep technical collaboration. From JIT and performance discussions to packaging, language design, ecosystem infrastructure, and mentorship, the event accelerated key work on Python’s future. The PSF sends a huge thanks toArm for hosting! |

Celebrating 2025 CSAsThe PSF Community Service Awards (CSAs) are a formal way for the PSF Board of Directors to offer recognition of work which, in its opinion, significantly improves the Foundation's fulfillment of its mission and benefits the broader Python community. These awards shine a light on the incredible people who are the heart and soul of our community– those whose dedication, creativity, and generosity help the PSF fulfill its mission. The PSF CSAs celebrate individuals who have been truly invaluable, inspiring others through their example, and demonstrate that service to the Python community leads to recognition and reward.
The PSF is pleased to share our 2025 CSA recipients:
Jay Miller
Katie McLaughlin
Matt Lebrun
Micaela Reyes
Sarah Kuchinsky
Rodrigo Girão Serrão
If you know of someone in the Python community deserving of a PSF CSA award, please submit them to the PSF Board via psf@python.org at any time. You can read more aboutPSF CSAs on our website. |

Sharing about the PSF's Financial Outlook In ablog post we published in November 2025, we shared a candid look at the PSF’s financial picture in advance of our 2025 end-of-year fundraiser and how recent grant decisions, rising costs, and growing demand intersect. We connected the dots between community support, our financial runway, and the essential work we sustain, like Python infrastructure and PyCon US. The post highlights both the challenges we faced and the generosity of our community that has helped us continue moving forward. Check outthe blog post to learn more about our outlook, what the PSF is doing to bolster our financial security, and how you can help!
The PSF has withdrawn a $1.5 million proposal to US government grant program In January 2025,the PSF applied for a $1.5M grant from the US National Science Foundation (NSF) to make innovative improvements to packaging security—and we were recommended for funding! But as a condition of funding, we were asked to affirm that we wouldn’t undertake any diversity, equity, and inclusion work, whether or not we used the government funds to do so. The PSF simply couldn’t agree to that statement, as facilitating “the growth of a diverse and international community of Python programmers” is written directly into our mission and core to our values, so we withdrew our application. In the end, it wasn’t a hard decision for the PSF to put our community and our values first, but it does mean we lost out on this large funding source.
The community’s response to this news blew us away, with a flood of supportive messages and a totally unexpected surge in donations, includinga community-organized matching drive. As a result, we hit our initial 2025 year-end fundraiser goal, set a new one, and hit that goal, too! Most importantly we are moved beyond words by our community coming together to stand with us and our mission.
PSF CoC WG Shares First Transparency ReportThePSF Code of Conduct Working Group has published itsfirst annual transparency report, covering the 2024 calendar year. This report shares insights into the group’s work to support a diverse, inclusive Python community and outlines new commitments to improved record keeping and regular annual reporting. Future transparency reports will be published each year in the first quarter and added to thePSF Code of Conduct documentation. If you have thoughts or feedback on how to make these reports more useful, we welcome you to send the Code of Conduct Working Group an email at conduct-wg@python.org.
