Klocwork and Validate enhancements
This release includes the following enhancements.
Back up projects and server information with minimal downtime
To minimize downtime, you can safely back up information without ever having to stop your servers. See hot backup Method 1: Use supported scripts to learn how to back up individual projects or Validate server configurations and restore them later.
Improved workflow for application token authentication
Authenticating a client in automated environments is now more streamlined and secure. This enhancement is especially useful for setups like Docker container deployments.
You can securely authenticate a client by storing the application token in a secret storage system such as Docker Secrets, then use your system's automated interaction methods to pass the token using the kwauth -t command.
For more information, see Authentication using application tokens.
Added support for regular expressions when creating modules in Java
Regular expressions are now supported along with Glob for pattern matching when you create modules in Java. A wide range of standard regex characters are supported for precise pattern matching. For more information and examples, see Creating a module.
Updated taxonomy page for improved navigation
To reduce visual clutter and simplify navigation, taxonomy categories are now collapsed by default. Categories will expand when you click on them or search the page. To expand or collapse all categories at once, use the top menu buttons.
Added confirmation step for editing multiple issues at once
To help ensure that your bulk changes are intentional, a confirmation box now appears when you edit multiple issues at once from the search screen.
Improved CI build logs for better visibility and troubleshooting
To provides a comprehensive view of the build process, CI build logs now contain both the analysis and the import build logs, making it easier to debug and track the progress of CI builds.
C and C++ enhancements
In this release, we:
- Added full C and C++ support for the Bazel build system on Windows and Linux
-
Replaced existing community MISRA checkers with Klocwork supported checkers
Java enhancements
In this release, we:
-
Added full Java support for the Bazel build system on both Windows and Linux

Plug-ins and extensions
In this release, we:
-
Upgraded the JetBrains IDEs (IDEA, CLion, and Android Studio) plug-ins to version 2024.2
-
Added SAML/OIDC authentication to the VS Code plug-in, allowing you to authenticate securely with the Validate server and reducing the need for multiple passwords
