- Support for PLAYSTATION Network titles has been expanded.

- [Dynamic Normalizer] has been added as a feature under [Sound Settings] in [Settings].
It should be noted that this upgrade will render homebrew useless on your system, and may prevent you from downgrading indefinitely. While we fully support Sony's endeavors on the system, we want you to make an educated choice before deciding to upgrade or not. Of course, this upgrade is but a taste of things to come: Sony will most likely include an even more robust feature set in the next major upgrade.
For those of you unable to access Network Update, feel free to download the upgrade from us. Connect your PSP via USB and save in PSP/GAME/UPDATE.
[Update 1: News from QJ suggests that people with custom firmware should not upgrade, as your systems may become bricked.]
