There will be some recommendations made when the French investigators release another preliminary report later this week, this article says, a.o. the following:
the BEA is expected to make at least three recommendations on general aircraft safety, this source said.These include extending the life of locator beacons attached to the flight recorders to 90 days from 30 days.
Regulators could also be asked to consider ordering further beacons to be attached to important parts of the aircraft structure to assist in locating wreckage in the event of a crash. Such beacons would need to be active for 30 days.

... like I think I said earlier, extending the battery life of the pingers is the first obviously reasonable thing to do and probably the quickest thing to fix, but there needs to be regulation in place also - which will take itīs own time.
