Playstation 4's new 3.00 firmware has already gone out in beta form to some users in Japan and the details of what's included have spilled onto the rest of the Internet.
According to Polygon:
In addition to the usual user interface enhancements, v3.00 brings with it the addition of YouTube broadcasting — just in time for YouTube's big new gaming push due to launch "this summer" — and support for 10-second clips for Twitter.
Also included in the v3.00 beta: an "Events" menu to find and watch events related to PlayStation (we imagine press conferences here); a "Community" feature where you can make a new community or join an existing one; and new ways to more easily find and join games your friends are currently playing.
It's been since March that the most recent 2.5 update brought suspend/resume, accessibility controls and higher frame rate for share play. And while there's no set date yet for when 3.00 will arrive, it shouldn't be too long of a wait.
