In this version there are improvements, which, in my opinion, deserve a small note.

From the article:
A much more interesting feature is that a mechanism of virtual values was significantly redesigned in the kernel of C++ analyzer. For example, now the analyzer performs a double loop passage, which allows it to define the range of possible values of variables, changing in a loop, more accurately. So don't be surprised if the analyzer starts issuing many warnings for that code which used to seem correct for the analyzer.
