  • A new C/C++ dataflow library (semmle.code.cpp.dataflow.new.DataFlow) has been added. The new library behaves much more like the dataflow library of other CodeQL supported languages by following use-use dataflow paths instead of def-use dataflow paths. The new library also better supports dataflow through indirections, and new predicates such as Node::asIndirectExpr have been added to facilitate working with indirections.

    The semmle.code.cpp.ir.dataflow.DataFlow library is now identical to the new semmle.code.cpp.dataflow.new.DataFlow library.
