- [X] (JK) NumPy 2.0
48+
- Discussion about how to get more info about NumPy version used in a build
49+
- https://github.com/numpy/numpy/pull/24861
50+
- https://github.com/conda-forge/conda-forge.github.io/issues/1997
51+
- [X] (HV) archspec-enabled packages
52+
- leaving lots of perf on the table; distros moving to x64-v2 or [even](https://www.phoronix.com/news/CentOS-ISA-Experiment-Perform) v3 baseline ()
53+
- [CF issue](https://github.com/conda-forge/conda-forge.github.io/issues/1261) open since ~2.5yrs; [CEP issue](https://github.com/conda-incubator/ceps/issues/59) a few months ago -- next steps?
54+
- (IF,CHL) We could probably re-purpose the existing `__archspec` virtual package to expose/proxy the HWCAPS/feature level; would not require additional changes conda to get some support for tuned packages
55+
- See https://github.com/conda-incubator/ceps/issues/59#issuecomment-1636844274
56+
- https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels
57+
- (CHL) CEP potentially goes way deeper and would expose things like individual CPU feature flags. (Original in-person discussion at SciPy 2023 was around discovering specific AVX-512, AES-NI, and ARM instructions.)
58+
- [X] (BH) Where is the best place to learn about/peek into conda-forge build automation?
59+
- Feedstock builds: conda-smithy provides the starting configuration, conda-forge-ci-setup handles some stuff at runtime, docker-images creates the base image for Linux. Automation around feedstocks... regro/cf-scripts is the start.
60+
- https://cf-infra-docs.netlify.app/docs/fundamentals/life-cycle/ for some big picture docs (non-official)
61+
- [X] (JK) m2 recipes
62+
- https://github.com/conda-forge/staged-recipes/pull/24112
63+
- https://github.com/conda-forge/m2-builds
64+
- conda-msys2:matrix.org
65+
- [x] (JK) AlmaLinux 8
66+
- CDTs need to be setup
67+
- [x] (JK) macOS 10.13
68+
- https://github.com/conda-forge/conda-forge.github.io/issues/1844
69+
- https://github.com/conda/conda-build/pull/4999
70+
- Needs reviews
71+
- [x] (JK) Windows ARM
72+
- compatibility status?
73+
- conda-forge usage
74+
- (IF) Got Windows ARM machine
75+
- (IF) Need to gen GHA token to give to them for CI setup (planned at end of month)
76+
- (IF) Will need to some cross-compilation to support building some of the packages for Windows ARM (from x86_64)
77+
- (MRB) Load?
78+
- (IF) Not worried about this as ramp up time will be long
79+
- (IF) They also will give us more if needed
80+
- (JRG) Have admin service logic to add/remove CI services
81+
- [ ] (HV) Asking Microsoft for more CI jobs
82+
- (JRG) Moving to GHA as an option
83+
- (MRB) Need to be careful having jobs that generate jobs on GHA (DoS risk)
84+
- [ ] (JK) Conda/conda-build/mamba/boa/Miniforge
85+
- (JRG) Can use `conda-libmamba-solver` in `conda-build` (starting w/23.9.0)
86+
- This has also been tested in staged-recipes
87+
- (WV) Regarding `boa`, might be best to move `conda-build` with `conda-libmamba-solver`
88+
- (HV) Will this allow us to update `conda-build` in feedstocks
89+
- Yes +3
90+
- (JRG) Can also opt-in with `conda-forge.yml`
91+
- Link:
92+
- (JK) Let's test on feedstocks a bit and see how it goes
93+
94+
- [ ] (CA) CDN issues
95+
- granular package delay monitoring coming soon
96+
- some packages can't be downloaded from CDN
97+
- Files were uploaded, but no release record was added
98+
- Now working on fixing the 20-30 packages affected in cf
99+
- Also adding logic now to track delay time
100+

101+
- [ ] (JRG) CZI EOSS6 LOI submission: https://github.com/conda-forge/conda-forge.github.io/pull/2019
