Other discussions (if time permits)

• Long-term Mac Intel support
  • Jeff to poll NIST summer students to see how much use we have from Mac Intel - summer 2026
  • No known developers with a working Intel Mac that runs MacOS 15...
  • Dependency support on Intel Macs will be a huge factor in this decision - Piotr
  • Numpy support through 2026-ish - conda started removing support in August 2025
  • Stop support as of v6.2.0 likely
• Py3.14 support
  • Tests already run python 3.14
  • When to move to for builds? v7.0 a likely good transition
  • Any new features we should be aware of? Native multithreading!
  • py3.15 will be available in Oct. 2026... but what about dependency support?
• Invariant
  • Fail early or is slope >= 0.0 valid?
