The PlayStation 3 is 19 years old this year, however, Sony has just released a crucial update for those still using it in their home cinema setups. It's a minor change that many won't notice, but if you use a PS3 to play Blu-rays, then this update has just saved you from replacing your console.
Sony released system software update 4.92 earlier this month, which refreshes the console's Blu-ray encryption key; though the patch notes simply stated this update "improved system performance". Without this system update, the PS3 would not be able to play Blu-ray discs due to the inclusion of Advanced Access Content System (AACS).
