Lataa CLion 2026.2

CLion 2026.2 is now available, with improved agentic workflows and STM32 integration, simplified debugger configuration with debug profiles, and support for C++26 reflection, among other updates. Here are the highlights:
- CLion 2026.2 ships with a bundled skill that gives AI agents direct access to the debugger. The skill works with GDB, LLDB, and DAP-based debuggers and is available for ACP-compatible agents. To invoke it, use /clion-debugger in Claude Code or $clion-debugger in Codex. We plan to add more embedded-related debugging features in a future update.
- The IDE now supports STM32 Cube CLI, a new STM32 bundle manager that lets you download only the tools you need – such as CMake, ST-LINK GDB server, or GNU tools – and manage your development bundles directly in the IDE. You can use STM32 Cube CLI in the terminal or via Tools | STM32 Cube CLI.
- CLion now provides a new, unified settings section to configure all your debugging setups – local, remote, and embedded: Settings | Debugger | Debug Profiles.
- The IDE now supports the C++26 compile-time reflection, one of the most significant additions to the language in years. CLion provides highlighting and code analysis for reflection, available when using GCC 16.1 or newer.
- Among the Bazel integration updates are improvements to debugging. When starting a debug session, CLion now checks whether your project is built with debug symbols instead of automatically injecting debug flags. If debug symbols are missing, the IDE shows a warning, from which you can inject debug flags directly and continue the debug session.
- CLion Classic, the legacy C and C++ engine, has been unbundled from the IDE and is now available only as a plugin. To continue using it, install the C/C+​+​ Language Support via Classic Engine plugin from Settings | Plugins | Marketplace. Note that CLion Classic is no longer in development – all new language features are developed exclusively for CLion Nova.
