## Minutes

### Edition

NM: tmandry, what the story on the edition?

tmandry: There really haven't been meetings yet. The RFC was recently merged.

NM: I agree with Josh we should be looking at lang team candidates.

TC: Here is the 2024 edition survey:

tmandry: It needs more organization. I'm interested in doing that.

NM: I'm interested in the breaking changes.

TC: We should review our lints for what should become hard errors. I.e., what did we plan to do in the past that we should do now.

tmandry: Hopefully those would be tagged with the edition label.

NM: We should talk with bstrie and esteban.

tmandry: ...

NM: I'm expecting to start from a list of all of the things that have been proposed.

There's a spreadsheet we used last time. In particular the features tab of this:

[spreadsheet link](https://docs.google.com/spreadsheets/d/1chZ2SL9T444nvU9al1kQ7TJMwC3IVQQV2xIv1HWGQ_k/edit#gid=1034375760)

NM: This had all the things proposed with checkpoints.

tmandry: It's a short list.

NM: It was pruned. And we didn't have a lot that year.

sm: We have lots of things like <https://github.com/rust-lang/rust/issues/114447> that we know we'd like to do but have had zero progress.

tmandry: I'll set up a project tracking board.

NM/TC: Should we schedule it?

...

tmandry: What's the outcome we'd want for this meeting?

NM: We largely want to triage.

### cargo-script

NM: Maybe a whole hour on that would be premature.

pnkfelix: +1.

### T-types proposals

NM: If it'll take two weeks to get the editon done. Let's do one of the T-types ones ahead of that.
