Release 17.6 beta 1 (4.10.692):
New features:
  • When banking protection is terminated, all information from clipboard is wiped.

  • A pop-up reminder about restarting the computer is shown when malware removal by real-time or scheduled scanning (or a malfunction) requires the computer to be restarted.
  • The "Time limits" feature has been renamed to "Device use limits"; the functionality of the feature remains unchanged. Note that this change is only visible in English in this release.

One of the biggest change is that UI seems to move away from Qt. Namely, new UI is based on Microsoft .NET Framework 4.7.2 which brings many advantages - especially RAM usage reduction.

Even though it is not related to beta's build, I found interesting article:
Getting a grasp on AI and Machine Learning in cyber security
... the in-house malware detection engine, Hydra, in 2008.
“Engine Team collaborated closely with the Anti Malware Technologies Team that developed other client-side components, including DeepGuard, BlackLight, and Gemini – a machine-learning based malware detection engine used in conjunction with our client-side behavioral analysis logic.”
Finally some little info on Hydra and Virgo (I guess Virgo is new name for Gemini).

In another news:
Re: f-secure engines - F-Secure Community - 114383
We will soon release a new engine generation for one of our core engines, which will provide various improvements that are essential in combating the more adaptive and targeted attackers of the future. The new engine generation will be released in an update to all officially supported product versions, as well as to VirusTotal’s file verification service.
I'm secretly hoping it is something new, not Capricorn (Avira) engine...:D
Asked for confirmation.

My expressions: I've been running FS Protection beta for over a year and I'm really satisfied with the quality. I've reported some bugs, but all in all the software runs really smooth in my system - fast and stable.
One minus side is that sometimes I notice slowdown with newly downloaded file. It looks as if FS is doing cloud checkup on the file and (usually installer) icon is not visible during "checkup". Nor could I open or run it. Fortunately it does not happen often.
Moreover, the FP rate from DeepGuard blocking "new" files has drastically lowered. I used to get a lot more "FP-s" from DeepGuard (reputation block) (y)
