I am in the process of starting a new app, I am not sure whether to go for v3 or v4-beta at this stage.
As the migration from v3 to v4-beta seems cumbersome, does it make sense to start with v4? And if so, what would be the rough estimate timeline when v4 may be released?
There are some major issues open, such as retaining scroll position.
Please provide some understanding.
