Description

Python 3.14 is out, and I do love adding support for a new version of Python ASAP (#3164). As I learned last year though our dependencies do not do so as quickly.

Tasks

• Update CI workflows to test against Python 3.14
• Update CI workflows to build for python 3.14 (Conda-forge)
• Ensure python dependencies support python 3.14
  • Numpy
  • VTK: this is biggest hand up usually. They have built the infrastructure , but have yet to ship
  • h5py
  • scipy
  • ipython
  • matplotlib
  • pandas
  • lxml
  • uncertainties
  • setuptools
  • endf
• Deciding on how to handle stable free-threading now available in 3.14 (Incompatibility of mpi4py and multiprocessing in depletion #3640)
