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.

My coding setup now includes local LLMs but no more permission prompts

My journey to optimise my agentic coding setup has now led me to consider running an LLM locally and removing all permission prompts. Even though I don’t check every action of the agent anymore, I fee...

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...

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 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.

Some stats from core dev @hauntsaninja.bsky.social showing Python 3.14 had more usable packages on day 1 than other recent releases. New releases of #cibuildwheel adding 3.14 as optional and then default also helped. discuss.python.org/t/stats-on-p... #Python #Python314 #wheels #stats #PyPI

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.

2025-40: A week in conda-forge

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.

Cross compiling in the Conda ecosystem

Cross compiling is a fundamental capability in modern software development, allowing developers to build packages for different architectures without needing access to the target hardware.
