Exciting to reflect on the the first year of open source funding at Astral — looking forward to another year of growth :) astral.sh/blog/astral-...

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

In the latest version of uv, we've updated the build system for our managed Python versions to use the latest LLVM version and cherry-picked an extra fix for a performance bug (github.com/llvm/llvm-pr...) and the early benchmarks are pretty exciting! On M3 macOS

Python 3.14.0a5 is out today in uv 0.5.31 and includes a new tail calling interpreter which, from some quick benchmarks, looks like a 1.23x performance improvement !

Really excited to be working on CPython and upstreaming python-build-standalone patches!

Very excited about this transition and improving the distribution of Python! Reach out if you're interested in getting involved :) astral.sh/blog/python-...

I have high hopes for a new "Before posting in the issue tracker" issue in uv github.com/astral-sh/uv...
