## Discussion

- Discuss osx-64 - Intel 64-bit Macbooks EOL in August
    - Stats data on downloads to be checked
    - Can still produce packages for the existing packages on the platform (e.g. up to Python 3.13, NumPy 2.3)
    - Can also build and test wheels using public wheel builders
    - What does conda-forge do / provide?
        - Still have Intel macOS installer
        - Not clear on what packages are still built for it (need to check)
    - Conclusion: will gather more info to make a decision, see what upstream deps are doing.
- LLMs and open source (Copilot)
    - What do we accept / not accept?
    - https://github.com/numba/numba/pull/10133 - test with copilot
        - Did not go well - many iterations required to get nowhere near a proper solution for a simple task.
        - Conclusion: We cannot presently let LLMs do independent work.
    - Suggestions:
        - Contributors are responsible for actions taken on their behalf.
        - Contributors should understand the code they're submitting and the actions they're taking.
- LLVM 20
    - Have got to the bottom of all problems
    - Some are not fixable
        - Would require large complex MCJIT patch to fix
            - Certain things will have to be noted as broken
    - SVML patch port in progress
        - API for vectorization has changed non-trivially in LLVM 15 -> 20
        - 50-60% of hunks don't apply
    - Summary: there is a way through to get enough to work to proceed
    - Tested manually on Linux (Intel + AArch64) and macOS (AArch64)
    - ETA for Numba / llvmlite release kickoff
        - End of next week(1st August)
        - Staffing constraints suggest an extra week is possible
            - Suggest release around 11th August, if no other people available before
