Hi Eric,

How much of the stability fixes are coming from the built in reporting feature of CIS[/i]
>> The performance improvement also influence the UI which responds faster and lost its sluggishness. Were there changes made to the UI framework or are the improvements a result of the general improvement of performance?
UI framework is not changed, it is the result of general performance fixes, unrecognized items handling improvement and optimization of interaction between CIS components.
Performance improvements can be divided on several branches:
Improvements based on fixes of issues found and reported by forum users (especially by Pixo1, Megahertz, Ploget and you) - their specific environment highlighted several hidden issues which are basically invisible on “regular” environment, but still affect performance. Mostly all of them are about communication between CIS components.
Improvements based on code refactoring, new C++ standard benefits
Optimization of unrecognized items handling (especially noticeable when widget is enabled).
As for updated engine:
>> Is there a change how the AV engine handles things?
>>Were binaries codes more efficiently?
Was a different compiler used?[/i]
