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.

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...

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.

Virtual Packages in the Conda ecosystem
Virtual packages are a neat trick to inject system requirements into the SAT solver and resolve for compatible packages automatically. In this blog post we talk about how they are used in the Conda ecosystem to support complex cross-platform package distributions.

S3 support in Pixi and rattler-build
We're excited to announce S3 support across our entire toolchain – rattler, pixi, and rattler-build now support the most common cloud storage standard, thanks to contributions from our friends at QuantCo. This vendor-agnostic approach to distributing Conda packages represents a major step forward for the ecosystem, offering teams the flexibility to host packages on any S3-compatible provider (AWS, Cloudflare R2, Backblaze B2, Hetzner, and more) with built-in authentication and minimal vendor lock-in.
