The latest firmware for the PS3 has been released and it doesn’t look like they have done much new. It looks like the issues with the game Assassin’s Creed and the feature remote play were dealt with though.

Official Changelog

• Stability during playing some PLAYSTATION 3 format software has been improved.
• Stability of System Software including Internet Browser and Information Board has been improved.
• Stability of the upscaler for PlayStation 2 format software has been improved. (Playability of PlayStation 2 depends on model)
• [Remote Start] feature is changed to avoid unintended power on.
