What's new in Klocwork 2020.1
Here are the highlights for Klocwork 2020.1. If you're upgrading, also see the Limitations for items that affect how you use Klocwork.
Community checkers and taxonomies
We've leveraged our deep ties with the wider Klocwork community to bring you a series of new taxonomies and community checkers. In doing so, we've added close to 200 community checkers to Klocwork across our supported languages: C/C++, C#, and Java. For more information, see the following:
- AUTOSAR community checker reference
- CERT community C and C++ checker reference
- Klocwork Quality Standard community C and C++ checker reference
- MISRA C:2012 community checker reference
- Klocwork Quality Standard community C# checker reference
- Klocwork Quality Standard community Java checker reference
- CERT Java IDs mapped Klocwork Java checkers
HIS metrics configuration file
The 'his_metrics_community.mconf' file may be of interest to you if your projects focus on automotive industry standards. HIS (Hersteller Initiative Software) was created from five working groups in the automotive industry whose goal is the production of agreed standards. For more information, see Adding the community HIS Metrics configuration file.
Performance improvements
We've upgraded several components in our toolchain to leverage 64-bit architecture, so Klocwork can more effectively analyze large, complex code bases, and projects.
Analysis engine enhancement
We've updated our analysis engine for accuracy and defect detection related to nested namespaces, references, and templates. On some Open Source projects that we benchmark against we've seen up to a 28% increase in defects detected.
Improved Knowledge Bases
We've overhauled the Knowledge Bases we include with Klocwork. You'll see better analysis accuracy in code using the standard C++ library related to smart pointers, utilities, and concurrency, to name a few.
MISRA checkers and taxonomies now fully integrated
In this release, we've integrated all of the MISRA taxonomies and checkers into Klocwork by default, so you no longer need to install and deploy MISRA checker packages separately. Configuring your project to validate against a MISRA taxonomy is now as easy as adding any of our other industry-specific taxonomies. For more information, see Configuring industry-specific coding standards and checkers.
Klocwork checker improvements
From release to release, we improve issue detection to bring state-of-the-art capabilities to our customers. As a result, expect your analysis results to change as accuracy and coverage improve.

Klocwork release numbering
We've updated our release numbering strategy. Going forward, the first release each year will have the year as the major release number and 1 as the minor release number, for example, 2020.1. Subsequent planned releases will increment the minor number, for example, 2020.2, 2020.3, and 2020.4.
Licensing
2019 licenses are not compatible with Klocwork 2020.4. You need a new license to use the latest version of the product. Contact license@perforce.com to obtain a new license.
We upgraded the version of FlexNet Publisher that we support for Windows and Linux to version 2018 R4 (11.16.2). If you are using your own FlexNet Publisher license server, ensure you upgrade to this or a newer version. You can also use the license server included with Klocwork 2020.1.
Checker support levels
With the introduction of community checkers, we've developed a set of support levels that explain the types of support we offer for the checkers we provide. For more information, see checker support levels.
End of support announcements
As of this release we have ended support for the Microsoft Visual Studio addin. Our Microsoft Visual Studio Extension (kw-vsplugin.vsix) contains the complete feature set and supports Visual Studio versions 2012 to 2019.
Klocwork 2019.3 was the last supported release of the Vim plug-in.
Maintenance for Klocwork 2018 ending
Maintenance for all versions of Klocwork 2018 is ending: the end of maintenance (EOM) date is February 29, 2020; the end of sale (EOS) date is also February 29, 2020. For information about the availability of support for any release of Klocwork, see the Klocwork Product Lifecycle.
Developer Network
In October, 2018, our technical Support Center at https://techsupport.roguewave.com/ was upgraded to include Klocwork. As part of that transition, Developer Network is no longer available.
Portal licensing changes
Klocwork has implemented additional licensing checks related to running the Klocwork Server, which, among other things, underpins the Klocwork portal. We recommend you validate your licensing needs to ensure you have a sufficient number of web service licenses.
