conda-forge also has Python 3.14 uploaded now, and as we did in the last releases, we were already able to rebuild a large chunk of packages (over 40%) before the final release. We have documented our Python 3.14 relase day support in a blog post: Python 3.14 is already usable on conda-forge (not just available) | conda-forge | community-driven packaging for conda
In general, you can see the Python 3.14 support on the status page.
