We helped to coordinate three security responses this week: - Pixi 0.82.1 revokes the eMudhra certificate, please update - PHP 8.5.12 was released by us on conda-forge - litellm 1.107.0 quarantined and blocked on prefix Read more about conda.org/blog/2026-1...

Conda, Mamba and Pixi users: update your tools and CA packages after the eMudhra certificate compromise. Follow the instructions for your installation, including existing environments: buff.ly/Oq9uv0w

Super stoked that SciCommander (track provenance for any file produced by your ad-hoc shell usage into HTML reports & more) is now on @conda-forge.org! 🥳 Install with: conda install conda-forge::scicommander pixi add scicommander anaconda.org/channels/con... Poster for info 👇

Conda packages have extras now. Optional dependency groups you declare and then consume, via v3 repodata. Plus when conditions and variant flags.

CEP 48, which brings conditionals and extras to your @conda.org dependencies, is now accepted! This means you will soon be able to type things like `typing-extensions[when='python<=3.10']`  and `scipy[extras=test]` 🚀 github.com/conda/ceps/b...

A single Python file can now carry its own environment. pixi run --script hello.py Pixi reads PEP 723 inline metadata. No pixi.toml, no .pixi folder, no lock file unless you ask for one.

pixi 0.76 can now run standalone python scripts in isolated, on-demand environments. dependencies live inline via PEP 723, like uv supports, but pixi can layer on conda and system dependencies too. fun to build this with @prefix.dev folks. coming to a @marimo.io notebook near you SOON.

The big RISC-V migration has ... begun! Check out the status here: Big thanks to all maintainers helping out! conda-forge.org/status/migr...

New community tool: a live dashboard for the conda-forge staged-recipes queue. See which new packages are waiting for review, what's passing CI, and where things are stuck, all in one place. srdb.thath.net/

My coding setup now includes local LLMs but no more permission prompts - sharing my recent improvements in AI coding (setup): uwekorn.com/2026/07/20/m... It goes back from IDE land to a more vim-like (i.e. barebones) setup.

Using bioconda usually means also configuring conda-forge and a few other channels by hand. Cumbersome, and easy to get wrong. Our new channel-relations CEP moves that info into repodata, so the solver just knows which channels belong together.

GLIM, the real-time 3D LiDAR SLAM framework, is now available on conda-forge. One-line install with pixi or conda instead of building from source. Good news for the robotics crowd. See it in action: www.youtube.com/watch?v=CIf...

Pixi v0.75.0 now ships with an --offline mode. Install your environments directly from the shared cache, even on the train or plane! 🛫 Find out more here: pixi.prefix.dev/latest/refe...

The rattler-build playground got a bit fancier! Now also generates recipes for PyPI, CRAN, and CPAN upstream sources. Try it out under playground.rattler.build

We've been driving one of the biggest changes to the conda ecosystem since its inception: repodata v3. Extras, conditional dependencies, and variant flags, expressed directly in the repodata. Now in beta 👇 prefix.dev/blog/repoda...

Do you know that CEP 41, the staging output in v1 recipe has been accepted and is available in #rattler-build? Time to convert your remaining feedstocks in @conda-forge.org and see if you can make it to tdejager.github.io/are-we-recip... 😊

📣 We are delighted to release mamba 2.6.0. 📣 This minor version includes the support for sharded repodata, significantly improving the UX of the project. 🔗 Read more about improvements on this blog post: medium.com/@julien.jerp... 🔗 For a full overview for the change: github.com/mamba-org/ma...

Two of the PyConDE sprints will be dedicated to the @conda.org ecosystem! I'll lead the session on conda-smithy, one of the tools behind @conda-forge.org! ・📍 Where: Darmstadt, Germany ・📅 When: Monday, Apr 13th 2026 ・🌐 More info: 2026.pycon.de/sprints/#acc...

Pytorch + Ultralytics + ROS2 Humble on a Nvidia Jetson Nano with no Docker! Pixi, together with @condaforge and @RoboStack, makes this possible! #ROS #nvidia #opencv

The RFC period has started on the "staging cache" CEP for the v1 recipe format. This might sound like gibberish but is a powerful feature that will allow us to convert more (complicated!) packages on @condaforge to the V1 recipe format!

The notebook.link team is building "serverless scientific computing" on top of the modern Conda ecosystem & the prefix.dev package server. Read the guest blog on how they shipped interactive WASM for Python, R, C++, Fortran and more: prefix.dev/blog/server...

"Building From Source Shouldn't Be This Hard" That's our motto, read our latest blogpost to understand what we're building and how Pixi already helps you with today! 🗞️ Read it here: prefix.dev/blog/buildi... #pacakgemanagement #pixi #ROS #condaforge

More Pixi stakeholders! Thanks Pavel and @quantco.com for being true Pixi & @conda-forge.org supporters.

We improved our package builder Rattler-Build a lot over the past months, so we wrote a blog post about it! prefix.dev/blog/whats-...

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! 🎉 Full details at conda.org/blog/2026-03...

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: www.youtube.com/watch?v=HOq...

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.” github.com/cranmer/sbi-...

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. prefix.dev/blog/virtua...

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! prefix.dev/blog/s3-sup...

🚀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. www.npmjs.com/package/@co...

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.
