I had the driver version 4.4.0.0 from 19.04.2023 installed. I installed SoftPerfect RAM Disk 4.4.2, but the driver version remained the same.
If I uninstall SoftPerfect RAM Disk, restart the computer, and install SoftPerfect RAM Disk 4.4.2 again, the driver is updated to version 4.4.2.0 from 05.11.2024.
