Belarc Advisor Free v11.0.0 is now available, and alternate download sites like MajorGeeks indicate this new version was released around 04-Sep-2021. I haven't been able to find a change log, but the official download page at https://www.belarc.com/products_belarc_advisor notes this new version is now compatible with Windows 11.
I also noticed that v11.0.0, unlike the previous v9.7.0, now correctly displays the Security Benchmark Score at the top of my report and has a detailed section that gives a Pass / Partial / Fail score for 147 security-related Windows settings for my Win 10 Pro machine. For some reason, my Security Benchmark Score was always shown as "Unavailable" with previous versions of Belarc Advisor.
