Last month, AMD released a new chipset driver version 8.01.20.513. The package added Windows 11 25H2 support for several of the included drivers like the 3D V-cache optimzer, and more. If you are wondering, these chipset drivers are crucial updates which can add support for upcoming features like the new performance boosting feature we covered earlier today.
With the previous update, AMD had noted that a couple of drivers like those for the AMS Mailbox and S0i3 filter were not included. Today the company has published a new driver with these baked in, and the previous optimizations are also there as it's a cumulative release. Thus if you did not update last time, you need not worry as only this latest driver is necessary.
Here is what is new in the release:

For those who may not be familiar with it, the S0i3 or Modern Standby is one of the S0ix system idle standby power states wherein the exit state of S0i3 is around ~3ms, and allows the system to quickly wake if the user wants to actively use the system again. The Host System Management Port (HSMP) interface via mailbox registers helps control these and other such power management functions via the commands and requests it receives.
Speaking of power management, the PMF or Platform Management Framework driver has also received an update. It aids in making dynamic adjustments to performance, fan curves, and power distribution based on real-time sensor data and user behavior. The necessary sensor data is obtained via the AMD SFH or sensor fusion hub. It is a dedicated low power coprocessor assigned to collect sensor data only, similar to the Intel Integrated Sensor Fusion Hub (ISH).
Here is the the full release notes for the new driver:
