Yesterday Sony Network Entertainment VP, Eric Lempel, reported that system update v3.72 would be launching “soon.”
Having launched overnight, like the majority of 0.01 incremental updates, it’s nothing major, just a few system stability improvements for software and the PlayStation Network.
Early reports pointed at issues with Netflix, but these seem to have been resolved. The update is primarily meant to sort out automatic downloads, which have been broken for Plus subscribers since recent updates.
