Add notification version 4 with source channel name and type

[3v1n0]

I often receive messages from users but I've multiple channels opened with them and I'm not sure from where the message is coming from (private message or a specific channel?).

So it would be nice to provide the notification source information too.

Thanks! I've updated the title to make the solution clear for when we can get around to implementing it.

Do we need to add a new version?

Can't we just extend the current object? In any case I'd suggest you to start versioning the object itself so that one can just rely on that at script level.

Starting with version 2, the object data does indeed already contain a version; see this. As for whether to add a new version, yes, that's my plan. Extending the current object without adding a new version changes what version "3" means, and that defeats the purpose of versions.
