<\/figure>\n\n\n\nYou can download CLion 2025.1 from the link below, via the Toolbox App<\/a>, as a snap package if you\u2019re using Ubuntu, or via a patch update from version 2024.3.<\/p>\n\n\n\n <\/i>DOWNLOAD CLION 2025.1<\/a><\/p>\n\n\n\n In this release, CLion Nova has received some of the most requested features, including support for out-of-project files, multiple settings, actions, and smart keys, and basic Objective-C support.<\/p>\n\n\n\n CLion Nova now provides full code analysis and code assistance for header and source files that are not included in a project<\/a>. For example, when you open an out-of-project The current implementation covers most of the known use cases. However, there are some edge cases<\/a> we plan to address after receiving feedback.<\/p>\n\n\n\n You can now get syntax highlighting, code completion suggestions, warnings, and other editor features when working with Objective-C source files. Header files, however, may not be handled correctly, and some features, including refactorings and smart keys, may not work.<\/p>\n\n\n\n If you need the same Objective-C support in CLion Nova that you get in CLion Classic, please follow or upvote CPP-37281<\/a>.<\/p>\n\n\n\n CLion Nova has gained several settings, actions, and smart keys that were previously exclusive to CLion Classic, making development with the new language engine even more convenient. Here are just a few examples:<\/p>\n\n\n\n <\/p>\n\n\n\n Read our documentation to learn more about all of the available actions<\/a> and smart keys<\/a>, as well as their shortcuts.<\/p>\n\n\n\n CLion Nova now supports the GoogleTest<\/a> and Catch2<\/a> testing frameworks in Bazel projects. However, there are still some limitations<\/a>.<\/p>\n\n\n\n To learn more about the basics of unit testing and how to use testing tools in CLion, read our documentation<\/a>.<\/p>\n\n\n\n Updates for the debugger include Qt renderers for user-friendly data representation when debugging Qt applications, support for custom LLDB debuggers and custom locations for Qt renderers, also known as Qt pretty printers and Qt debugging helpers, allow you to view variables, such as This feature is enabled by default, but to use it, you need to download the Qt renderers and specify the path to them:<\/p>\n\n\n\n Note that Qt renderers don\u2019t yet work with remote and WSL toolchains.<\/p>\n\n\n\n In addition to the bundled LLDB, which is currently v19.1.3, you can now use a custom LLDB when working on macOS or Linux. This allows you to choose the version best suited to the requirements of your project.<\/p>\n\n\n\n You can select a custom LLDB in Settings | Toolchains | Debugger<\/em>. CLion will then automatically try to find the custom LLDB installed on your system. You can also manually specify its location.<\/p>\n\n\n\n Note that custom LLDBs don\u2019t yet work with WSL, Docker, or Remote Host toolchains and are not currently available for Windows.<\/p>\n\n\n\n When debugging an ML or computer vision application that uses OpenCV, you can now view two-channel matrices \u2013 such as To do this, select the Threads & Variables<\/em> pane of the debugger when your program is suspended at a breakpoint, navigate to the two-channel matrix, and click View as image<\/em>.<\/p>\n\n\n\n Natvis renderers, also known as Natvis visualizers, allow you to define visualization rules for various data types when using the MSVC debugger. Previously, CLion\u2019s functionality was limited to loading You can add an additional directory with Natvis renderers in Settings | Build, Execution, Deployment | Debugger | Data Views | C\/C++<\/em>.<\/p>\n\n\n\n Enhancements for embedded development include a new ST-LINK debug server configuration option, the updated STM32CubeMX New Project<\/em> wizard, and improvements to the Serial Port Monitor plugin.<\/p>\n\n\n\n When debugging STM32 projects, you can now use the ST-LINK debug server template, which was designed specifically for STM32 chips. It includes only the essential settings, simplifying the configuration process.<\/p>\n\n\n\n To try the ST-LINK<\/em> template:<\/p>\n\n\n\n Note that the ST-LINK<\/em> configuration option currently only works with:<\/p>\n\n\n\n <\/p>\n\n\n\n You can learn more about debug servers in the documentation<\/a>.<\/p>\n\n\n\n The process of creating STM32CubeMX projects has been updated to improve usability and extend support to a broader range of STM32 chips and projects (read the documentation<\/a> for more details). CLion now uses the native STM32CubeMX approach to generate CMake files. This ensures that project creation is fully aligned with the official STM32CubeMX workflow and toolchain.<\/p>\n\n\n When you open the New Project<\/em> wizard and select STM32CubeMX<\/em>, you\u2019ll find detailed instructions on creating an STM32CubeMX project, including information about the actions you need to perform in STM32CubeMX.<\/p>\n\n\n\n We realize that the current approach to STM32CubeMX project creation is still not ideal, and we welcome your feedback as we continue to improve (CPP-42553<\/a>).<\/p>\n\n\n\n You can now view and manage the DTR, DSR, RTS, and CTS hardware control signals when working with the Serial Port Monitor plugin. This gives you more control over attached devices that use a serial port such as ESP32 and Arduino.<\/p>\n\n\n\n To enable hardware control signals:<\/p>\n\n\n\n The control options and indicators will then appear in the COM port tab.<\/p>\n\n\n\n In the same tool window, you can also enable timestamps to view them in the monitor output. This option is handy for tracking message sequences in detail when troubleshooting.<\/p>\n\n\n\n As part of our efforts to improve Zephyr West support<\/a>, this release introduces the ability to use the If you\u2019re working with Zephyr West projects, you can now use the You can pass the west build command options from Settings | Build, Execution, Deployment | Embedded Development | West | Advanced Settings<\/em>.<\/p>\n\n\n\n Sysbuild<\/a> is a build system that allows you to build multiple images for boards with multiple SoCs (systems on chip) or SoCs with multiple CPU cores. To enable it, pass The bundled CMake version has been updated to v3.31.4 and includes support for CMake Presets v10. Presets<\/a> are stored as JSON files and are useful when you want to specify common configurations and build options for a CMake project, for example, to share them with your teammates.<\/p>\n\n\n\n Our Bazel plugin<\/a> has received two of its most requested features: <\/p>\n\n\n\n <\/p>\n\n\n\n These enhancements allow you to use different toolchain configurations across platforms, making it easier to develop a wide range of projects, including automotive and embedded ones.<\/p>\n\n\n\n Read our blog post<\/a> to learn how to configure your Windows machine for C\/C++ development with Bazel, import a Bazel project into CLion, and set up a custom toolchain.<\/p>\n\n\n\n All AI Assistant<\/a> features are now free in CLion and other JetBrains IDEs, which makes AI-powered development more accessible and efficient. New AI features include the ability to handle natural language prompts for C\/C++ and a new edit mode for multi-file edits directly from the chat.<\/p>\n\n\n\n AI Assistant features are now free. Some of them, such as unlimited code completion and local model support, are completely unlimited, while others have limited credit-based access (learn more<\/a>). A new subscription system makes it easy to scale up as needed with the AI Pro and AI Ultimate tiers.<\/p>\n\n\n\n AI Assistant has received enhancements that increase productivity and reduce repetitive tasks, such as support for new cloud models like Claude 3.7 Sonnet and Gemini 2.0 Flash, smarter code completion, and a new edit mode for multi-file edits directly from the chat.<\/p>\n\n\n\n AI Assistant also has learned to understand natural language prompts for C\/C++. After you write a prompt and press Tab<\/em>, AI Assistant interprets it and translates it into code changes, taking your project\u2019s context into consideration.<\/p>\n\n\n We invite you to give CLion 2025.1 a try.
