Sony is letting people test PlayStation 4 firmware updates before they come out.
It's running a beta program to test the functionality of the console's next major system software update.
You can sign up here. You need a PS4, an internet connection and a master account - sub-accounts don't work.
Of note: beta testers can roll back to the previous PS4 system software update (v2.57) at any time.
The beta program begins on 2nd September.
Sony has yet to announce which features are planned for the update, but they've already leaked. Headline additions are Events, Communities and a new layout for the message screen. Elsewhere, you can broadcast your gameplay on YouTube, and upload video clips to Twitter, with a 10-second limit.
