3.1.98.0 was released to the Store around 2AM PST this morning (March 6th). We're throttling at 10% so it won't be available as an automatic update to all systems at this point.
We'll likely make the decision tomorrow on whether to open up to all systems as an automatic update.
3.1.98.0 Release Notes are as follows:
- Bug/Crash fixes to improve stability
- Support for variable-sized console
- Peripheral audio processing offloading (additional media whitelisting)
Finally, we are *not* yet releasing Windows 10 Version 1709 via Windows Update. Please maintain your systems on Windows 10 Version 1703.
