The wikipedia page doesn't seem to have any information about "record amounts of energy produced" at NIF. The closest thing I've found is a press release[1] that mentions "highest [neutron] yield achieved so far from a layered DT implosion". Neutron production should be proportional to the number of fusion events (and thus also the energy released). But, its odd that they don't claim this specifically.
