Hi Guys. This one apparently has quite a different setup, security wise. Anyway, here are the formally listed changes (haven't seen them elsewhere yet):
- support for Playstation Network titles has been expanded
- support for the MPEG-4 AVC format has been added under [Location Free Player]
- [Dynamic Normaliser] has been added as a feature under [Sound Settings] in [Settings]
I also read somewhere that there are some browser options to conserve memory (lower picture resolution) and such. I'm performing the upgrade now, will report if I find anything.
EDIT: Confirmed. Under [Settings] in de browser, there is now an option for [Conserve Memory] that can be turned on or off. "If you set this option to [On], less memory will be used but image quality will be reduced"
