Today was a good day for the Gnome ecosystem on @conda-forge.org! Two PRs merged to get more low level libraries: libadwaita, sassc, appstream, libshumate and json-glibc by Dan Yeaw and Felix Häcker.
I was intruiged by this post and made similar (but not comparable) plots for the Python 3.14 availability on conda-forge: uwekorn.com/2025/12/01/p...
Missed us at @europython? Here is the recording:

Week 41 this year was the week of the Python 3.14 release and also the last one I wrote a report on my @conda-forge.org activities: uwekorn.com/2025/10/20/w...
While I was at @pydataparis.bsky.social , I did not spend much time on @conda-forge.org, but in that week, at least some important milestones happened for the Python 3.14 migration, e.g. unblocking everything that depends on pandas. More details can be found in my report: uwekorn.com/2025/10/16/w...
Python 3.14 has been released two days ago. At the same time, we also uploaded a build of it to @conda-forge.org and about 40% of Python version dependent (mostly those with compiled code) were immediately available. See conda-forge.org/blog/2025/10...
Another week of reporting on my @conda-forge.org work: uwekorn.com/2025/10/14/w... This time, I started a mini-sprint on the Python 3.14 migration.
In our little deep dive series we're now exploring how cross-compilation in the Conda ecosystem works: prefix.dev/blog/cross-c.... Back in the days, @conda-forge.org rolled this out widely to support osx-arm64 early on, and now for linux-aarch64/ppc64le.
Pixi Global is known as a tool to manage CLI applications, but did you know that you can also install shell completions and even graphical user interfaces with it? Learn more by reading Lucas' and Julian's blog post: prefix.dev/blog/using-...
Ever wondered where all my GitHub contributions come from? I have document a week's worth of @conda-forge.org contributions: uwekorn.com/2025/09/18/w...
I plan to do this for 2-3 more weeks to get an overview where I spent my time. I hope there is also content in there that helps others.
Our server has recently delivered more than 1.000.000 packages for the first time. We've hit that mark a few more times since. Seeing this constant growth is fascinating and we are confident that our infrastructure will scale well beyond this number!
We're continuing our little deep dive series into Conda packaging. Mutex packages are useful to guide the SAT solver into specific parts of the dependency tree, and globally select either a GPU or CPU variant or similar features for an environment. prefix.dev/blog/what-a...
Today we're unveiling new Software Supply Chain features for the Conda ecosystem: the integration of Sigstore is in public beta on prefix! You can now create Sigstore attestations on Github Actions and cryptographically secure your supply chain with trusted publishing.
We “conda” believe it! In collaboration with 7ASecurity and @sovereign.tech, we carried out an audit of conda-forge. Read the details at our blog: ostif.org/conda-forge-...
@conda-forge.org and @conda.org are essential components of our stack. Thus, it is natural for us to work with the community there to make it ready for upcoming cyber(security) regulations. Read about our efforts at tech.quantco.com/blog/conda-r...
Reach out, if you would like to collaborate!
The documentation of @conda-forge.org is improving with example recipes for Go and Rust packages – providing useful starting points to get MORE packages into our ecosystem!
“Raise your hand if you were able to install everything with pixi and run the simulation-based inference tutorial notebook.”

I'm really looking forward to getting to teach this tutorial with @ruben-arts.bsky.social and John next week at #SciPy2025! This has been fun to collaborate with them on to create. I hope tutorial participants enjoy it and come away feeling they have a whole new toolkit to empower themselves with!
Ever wondered how Conda and Pixi "know" to install CUDA packages only on GPU machines? 🤔
Meet virtual packages - a clever solution to inject system compatibility information to the SAT solver to ensure compatibility.

Demystifying conda packages!
Celebrating 4 incredible years with @rjai.me! 🌟 As a conda steering committee member and conda-forge core team member, Jaime helps coordinate efforts that enable scientific breakthroughs. Here's to more years of community-driven innovation! 🙌 #CommunityImpact #OpenSource
These days you can easily use S3 buckets to host your Conda packages. @quantcotech folks have implemented support across pixi, rattler and rattler-build.
We're excited because we want Conda packages to be used everywhere without vendor lock-in!

🚀Last week, the #ScientificPython Developer Summit brought together 32 package maintainers from across the ecosystem at eScience UW in Seattle!
✨It was a great opportunity to collaborate on improving the tools that power scientific Python research.🧑🏽💻
Thanks to everyone that joined! 🧡
New release on @npmjs - the rattler WASM/JS bindings are now published under "@conda-org/rattler". Why would you want Conda packages in the browser? – to install WASM modules for Python, R, Lua, C/C++ and more, or build your own WASM powered applications.

Amazing blog post about using Pixi for ROS 2 on Windows. We're happy about the shoutout – that's the kind of complex setup that we want to make extremely easy with Pixi.
One of the fastest JIT in the world is now easy to install with `pixi` on Windows.
If you always wanted to try LuaJIT then you can just `pixi add luajit` – on Windows, macOS and Linux.
We recently celebrated 10 years of @condaforge on our Zulip. I'd love to hear your story if you are involved with conda-forge. The project has grown to over 30'000 packages, and still grows at a crazy rate.
🌟 Spotlight on @julianhofer.eu!
marimo + pixi: launch your notebooks in seconds.
This starter template pairs marimo with pixi for instant env setup, built‑in testing, linting & CI/CD — so you can dive straight into interactive notebooks.
