v4.0.0-rc.2

About

The third release candidate for v4.0.0 is here!
It contains many improvements that I found by looking at the code for way too long. I ended up changing quite a lot, which technically shouldn't happen between two release candidates, but I don't have any other release options at the moment 😅

Most importantly, I have deprecated the children snippet, and you should useitem instead, similar to how the slot was called in v3.0.0 and earlier versions.
The same applies to the onListItemsUpdate callback, where you should use onItemsUpdated instead, inspired by the naming of the event from v3.0.0 and earlier versions.
These two changes are backwards compatible, so you may see a TypeScript warning, but everything will remain functional until a potential v5.0.0 in the future, where deprecated APIs will be removed.
So I still recommend changing it!

I've hopefully also fixed the typings. This should help with errors, warnings, and the general development experience.

I promise that I won't change much more, if anything, until the final v4.0.0 release :D
