0.6.0

New Queries

• The query cpp/redundant-null-check-simple has been promoted to Code Scanning. The query finds cases where a pointer is compared to null after it has already been dereferenced. Such comparisons likely indicate a bug at the place where the pointer is dereferenced, or where the pointer is compared to null.

Minor Analysis Improvements

• The query cpp/tainted-arithmetic now also flags possible overflows in arithmetic assignment operations.
