## Discussion

- llvmlite PR gardening: potentially close https://github.com/numba/llvmlite/pull/1042 as it is partially superseded by some already-merged PRs and the remainder handled by https://github.com/numba/llvmlite/pull/1092
- Gantt chart for 2025 (existing: https://github.com/numba/numba/issues/9540)
    - New one to be produced after discussing plans for the year.
- Windows on ARM support
    - No plans as yet
    - Graham is interested / curious
    - Would need some hardware to test on
- Dates for talk on Olympus-HPC/proteus
    - Proposal: 28th Jan office hours slot
    - Arrangements TBC
    - Will post details into Discourse Announcement category when confirmed
- Release 0.61
    - Aim to tag on Thursday
    - Push dependent on success of build, may be as late as Monday
    - Subject to all going well.
- Split llvmlite FFI module out
    - FFI code is Python-version independent
    - llvmlite Python package could be noarch Python
    - Will allow different FFI packages for different LLVM versions
    - Will have API difference workarounds in llvmlite Python
- Meeting notes not uploaded to wiki since Oktober and reminder for this task has vanished from Anaconda slack -- what do we want to do.
    - Siu will do stuff on HackMD to make them indexed and available
    - A link is to be posted on discourse
    - A link is to be posted on the Numba wiki redirecting users to hackmd
