September's Max the Stack officially closed — but if you missed the ask, here’s one more chance to be part of what it funded this fall: grants, releases, workshops, and the maintainers keeping it all running. Max the Stack: hubs.la/Q04z5jcP0

Last day of Max the Stack. Every gift and every sponsorship this month goes directly toward keeping open source scientific computing funded through fall and winter. Thank you to everyone who’s already given — there’s still time to join them. Max the Stack: hubs.la/Q04ylYVm0

Two days. One deadline. The scientific computing stack you rely on keeps running because people choose to fund it — choose to be one of them before Oct 1. Max the Stack: hubs.la/Q04ylYM80

We're proud to be a community supporter of the Feature Store Summit 2026! 🎉 On Oct. 6, @hopsworks is bringing back this free online conference for the 6th time, with 15+ technical talks from teams at Spotify, Adyen, Uber, Airbnb, Delivery Hero, Zomato, and more. This year's theme is real-time context for agents: fresh features, low-latency serving, and the memory and retrieval systems that keep agents reliable in production. If you build data and ML systems, this is a great chance to learn from practitioners and connect with the community. Registration is free: hubs.la/Q04yshLk0

Three days left. Max the Stack closes Oct 1. If you’ve seen what your support funds this month — grants, releases, workshops, faster tools — this is the week to be part of it. Max the Stack: hubs.la/Q04ylYtF0

Optuna’s v5.0 release candidate is out, with the stable release planned for early September — and the team’s already building Rustuna, a fast Rust implementation of the project’s performance-critical pieces. That’s a project with room to innovate, not just maintain. Max the Stack by donating today at hubs.la/Q04ylYfp0

BONUS CONTENT: "4 voices, 1 Community." One stack that only works because people fund it. We’re doing one last recap of Give Me 5 Season 2 this week — catch up and donate before Max the Stack wraps: hubs.la/Q04ylJ1K0

Over the years, we’ve shared hundreds of talks, tutorials, ideas, and more for free on our YouTube account, PyDataTV (available at hubs.la/Q04ylHtV0)! We’ve been excited to grow this platform to over 170,000 subscribers, following along with the incredible content our community has developed. The best part is that every video is free to view. Help keep it open, free, and growing by supporting NumFOCUS and Maxing the Stack at hubs.la/Q04ylHpj0

Spyder’s second 6.2 alpha landed this month — new interface themes, Pandas dataframe export straight from the Variable Explorer, and Polars support. Small quality-of-life features add up to a better daily tool for thousands of scientific Python users at hubs.la/Q04ylDDc0

Bokeh 3.10 shipped with ASGI support — meaning Bokeh apps can now run on FastAPI, Starlette, Django, or Streamlit without Tornado. Plus GPU-accelerated rendering for filled polygons and faster load times for dashboard-heavy apps. Real feature work, funded by real support. Donate now: hubs.la/Q04x94Q-0

Q3 budget cycles are closing. If your team runs on the scientific Python stack, this is the window to make sure the projects you depend on stay funded going into winter. Max the Stack today: hubs.la/Q04x94x_0

ITK released version 5.4.7 this month — steady, incremental maintenance on a toolkit that powers medical and scientific image analysis worldwide. This is the unglamorous work that funding makes possible. Max the Stack and donate today at hubs.la/Q04x93Zh0

Thank you to everyone who came by to chat with us during @pydataamsterdam 2026 last week! And an extra special thank you to the organizers and volunteers who helped pull the whole event together. 🧡

Julia’s team has posted release notes for the upcoming v1.13.0 — the next step in a language built for scientific and numerical computing. Behind every release cycle is a community that keeps showing up, and support that keeps them able to. Max the Stack: hubs.la/Q04x93Bm0

CuPy shipped v14.2 this month — another steady release in a project that GPU-accelerates NumPy-style computing for thousands of researchers. Releases like this don’t happen without maintainers who have the time and backing to ship them. Donate now at hubs.la/Q04x938T0

What a great first day of PyData Amsterdam! If you’re there, be sure to stop by the NumFOCUS booth. We’d love to chat!
