TCP Connections With DAP Debuggers, Different Formats for Numeric Values, and More in CLion 2026.1 EAP | The CLion Blog

CLion 2026.1's Early Access Program (EAP) introduces a variety of enhancements to debugging, build tools, and project formats, aiming to improve user experience and efficiency. Key updates include the ability to communicate with Debug Adapter Protocol (DAP) debuggers over TCP, offering more flexibility in debugger choices, and allowing users to view numeric values in different formats, such as decimal, hexadecimal, and binary. Debugging in remote development mode has been made more responsive and stable, with significant performance improvements for the LLDB-based custom debugger when using Natvis expressions. The bundled LLDB version has been updated, and new support for custom project models simplifies code insight and migration from VS Code. Additionally, CLion now provides full code insight for external projects and offers enhanced CMake support with code completion for command-line options and more descriptive preset names. Language support enhancements include unit testing support for Meson projects and improved code folding features in the CLion Nova engine. Users are encouraged to explore these new features during the EAP to help refine the software before its stable release.
