@nalimilan, is there an update on this?  I’ve noticed that all of the DataTables commits have been merged with DataFrames and that DataFrames now uses Nulls instead of DataArrays.  This is definitely a welcome update, I’d like to start migrating my packages from DataTables to DataFrames in anticipation of whatever the world will look like in 1.0, so I wanted to try to get some idea of how stable current plans are.
Also, @quinnj has overhauled DataStreams, and I’d like to get things up and running with the new version, I was wondering if there was any willingness to start porting things over (I can definitely help with this).
Thanks to everyone for their ongoing efforts.
