index.d.ts is missing a number of type signatures

[growlycode]

In index.d.ts, a lot of recent changes have not been applied e.g.

find<Q, T>(selector: string): FindWrapper<Q, T>;

should be

find<Q, T>(selector: preact.VNode | string): FindWrapper<Q, T>;

I think we updated most of these, if there are others missing please re-open a PR?
