Re the latest version of the EN-EL15 battery, as I understand it the cell manufacturers have very slightly increased the capacity of the chemistry by using slightly thinner membrane with improved resistance to leakage, which is how the Eneloop, Panasonic and Fujitsu batteries (I am led to believe they all come out of the same factory) achieve their better performance. None of the leading manufacturers make the older type cells any more, The EN-EL3 cells were Samsung, the EN-EL15 cells may well also be Samsung.
In order to get the extra capacity I understand you need to use a Z charger, which slightly increases the charge compared with the original chargers. I will be collecting one mid May.
Robert, as far as I know Eneloop is a product of Panasonic, they produce Ni-Mh batteries and the chemistry is very different from the Li-Ion cells used in the EN-EL15 thus their construction is equally different. Thus it is very unlikely that the same method will increase the capacity of both battery types.
