Sony Computer Entertainment just made a new update available for the PS3, numbered 4.76. The patch notes are pretty much what many would expect:
“Improved system software ability during use of some features.”
At the moment of this writing, the update still isn’t available for download on the web, so you’ll need to get it directly on the console via the System Update option of the menu.
Ultimately, stability definitely isn’t a bad thing, and after all PS4 users are getting a pretty beefy 3.00 patch soon, after much “stability.” Will the veteran PS3 ever get a 5.00? We’ll have to wait and see.
