Europe and China are both investing heavily in RISC-V chips. Thanks to the OpenKylin project the @conda-forge.org project is making progress as well. Today I ran Pixi on RISC-V for the first time.
If you're investing in RISC-V infrastructure and want the package tooling to match — let's talk.
A brain in a conda package. What!?

The latest Pixi releases and installer on Windows are properly signed with a Microsoft Certificate.
Would it be useful to integrate signing for macOS and Windows into rattler-build?
Everyone loves shell completions, right? With carapace, you get amazing shell completions for most CLI tools, including Pixi since the latest release. This works on all platforms and shells.
Pixi skills are kinda cool. A couple extremely useful ones already hosted on prefix – such as the `conda-forge` skill, or the `rattler-build` skill. It's useful because it contains a bunch of expert knowledge, digestible for agents.
The @condaproject is moving forward with formalizing the current implemented standards! Strengthening the whole ecosystem and promoting collaboration.
rattler-build handles thousands of real world packages, and they often come with small patches. Historically, we used a mix of `git apply` and `patch`, but both have issues for cross-platform compatibility with a wide range of real-world patches. Now, we have our own Rust library
Adding `pycairo` was extremely easy thanks to all the work by @ihuicatls and the team at @QuantStack.

Last weekend I made `reportlab` a noarch package on @condaforge and added `pycairo` to emscripten-forge.
Now you can easily generate PDFs in notebook.link!
This is critical for a lot of agentic "business use cases".
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.
We're taking supply chain security seriously for the Conda ecosystem. That's why we integrate deeply with the @projectsigstore ecosystem for attestation – soon coming to recipes as well to validate source code (sdist, github release) attestations.
Many RISC-V experts at the @condaforge meeting today. This is going to move quickly! Pixi also just finished building for RISC-V, exciting stuff.

We're excited to announce Pixi GUI, developed by our working student Felix Häcker! With the goal to make Pixi accessible to a wider audience while also empowering expert users.

Should @OpenRoboticsOrg support #Pixi as an co-official installation tool on Linux?

We are thrilled to introduce notebook.link, a platform that lets you create, share, and run Jupyter notebooks instantly in your browser.
Powered by JupyterLite and WebAssembly, it supports Python, R, C++, and a full in-browser terminal experience.

The official @NVIDIA cuda-python project now also uses Pixi!

Pinning a dependency in Pixi is defaulting to semantic versioning, but there are more styles that you can use!
Did you know the channels have a priority to them? This can be important when you mix multiple channels in your Pixi workspace.
A conda package from GIT SOURCE? How?! 🤯 We might have been hinting at "pixi-build", but now we're unveiling what makes it work: pixi build backends. A build backend basically produces a "recipe" from language-specific metadata, and pixi build orchestrates the build.
PackagingCon is back in smaller format as a Devroom at FOSDEM 2026! We would love to see you there - and hear a lot of interesting talks.

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.
I have submitted by first draft PEP! 📦
PEP 804 complements PEP 725 ([external] dependency metadata) with a mapping mechanism to translate ecosystem-agnostic identifiers to your favourite package manager.

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!
