I have migrated to python 3.13.1 and hyve setup my ven from scratch and sudenly RUST dependencies are required which was not before. Is this intended to be?

Installing dependencies from requirements.txt into virtual environment .venv (in quiet mode)...

This is due to us having to support both Python 3.9 and Python 3.13, but there not being a numpy version that has having support for both. I have an idea for a way to change our requirements file to pull in the right numpy depending on your system's Python version, which should mean no rust is needed. I'll try it out next week. Thanks for filing, this was bothering me too.
For now, you can upgrade the numpy version in requirements.txt to the latest version in your fork.
