Jdbc Driver - What's New in ..

Hi there,

I am looking at the Jdbc driver documentation (first steps) and have the impression there is a docu which is version unrelated (how is works now).
I am looking for some more specific like:
. what is new is version xx.xx
. expected behaviour change(s)
This would help evaluating the testing effort to put into upgrading the Jdbc driver version and also concentrating attention to specific features when needed or applicable in a specific context.

Does anyone have reference, link to provide for the above?
thanks
