February 10, 2026: This release introduces new analysis capabilities and expands CodeCheck coverage with multiple new MISRA, CERT, and static analysis checks, while also improving the accuracy of existing checks. Several user-facing enhancements were added across the VS Code extension, Project Browser, command-line tooling, and MCP architecture support. The update also includes a wide range of bug fixes improving stability, parsing performance, compiler handling, and language support across C/C++, Java, Python, C#, and Web technologies.
