Cloud Imperium Games has confirmed that a fresh build of Alpha 4.10 is currently being put together for the test population. The statement, shared via r/starcitizen, doesn't lock in a specific PTU wave timeline yet, but signals that work is actively underway to get the next iteration into testers' hands.
As with previous 4.x builds, expect this update to bring bug fixes and refinements based on feedback from earlier test cycles rather than a wholesale content overhaul. CIG has not detailed exactly what changes or fixes are included in this pass, so specifics will likely surface once patch notes or a PTU invite wave go out.
For Star Citizen backers keeping an eye on testing opportunities, this is a good moment to watch official channels and the RSI Spectrum forums for the next PTU announcement, as builds like this typically precede a new wave of invites.
