@mit-mit @kwalrath - is there anything we need in the SDK prior to branching? (There already is an issue to remove the dart2aot binary.) . The rest appears to be in docs/site repos.

[kwalrath]

Should we move this to dart-lang/site-www?

[vsmenon]

@kwalrath - is there any update on this issue? I think @mit-mit is out this week.

[kwalrath]

I plan to do the site-www work next week. Is there anything you need me for in the sdk?

[mit-mit]

There is no work here that needs to land in the SDK. But I'd prefer to track it here to make sure we don't forget before launch.

@kwalrath what's the best way to track this for the release?

PRs, probably. I'm working on a PR for the dart2aot/dart2native doc updates.

I'll have a separate (smaller) PR for the FFI page.
