Can hatch install Python release candidates?

Asked first in #1722 but since I couldn't find a way to work I think it is not possible now, so making an issue as a feature request, if possible

Hello,

Thank you for the amazing tool, I really enjoy using it. Now that Python 3.13 is in RC2, I wanted to test my project using it to detect and fix breakages before the final version of Python 3.13 is released. However, reading through the documentation on hatch python it looks like this doesn't seem to work? I must have been holding this wrong, so I decided to ask here if there is a way to test Python release candidates.

While here, a side question: how long does it take between a new Python version being released and the release being visible to hatch?

Thank you!

Hatch uses 'standalone' Python builds from https://github.com/indygreg/python-build-standalone, and builds of Python 3.13.0 were just completed a few minutes ago. Minor releases usually show up there within a day or so of the source code release, but it took a few months to get the 3.13 major release built because there had been a large number of changes in the CPython build system.

Thank you! I'll close this since it's no longer needed then
