Project streams
For projects that have related streams, Klocwork now provides a consolidated issue list that provides a sum of all issues in both the project and all its related streams.

C#
We've improved support for the C# 7.1 language specification. We've also added new taxonomies for the OWASP Top 10 Security Risks.
C/C++
We've enhanced incremental analysis for mixed language projects and improved the accuracy and reduced false positives for several checkers.

- DISA STIG for C/C++
