CLion Early Access Program

We at JetBrains believe that making tools for developers should involve listening to them. Our Early Access Program lets the community participate in discussions devoted to our products and influence the development planning, from the early stages onwards.

Why should you try EAP builds?

Early Access Programs allow you to try pre-release versions of our software.

You can use them to evaluate the features which will be added to the next release. Please use the CLion issue tracker to report bugs and suggest new features.

This is an early access version of the product

You expressly acknowledge that this version of the product may not be reliable, may not work as intended and may contain errors. Any use of the EAP product is at your own risk.

2026.3 eap build 263.7031.19 Released: 2026년 10월 15일 No subscription required Release notes	A new EAP build for CLion 2026.3 is available. CLion can now visualize the memory layout of C and C++ classes, structs, and unions, so you can analyze memory usage more easily. Place the caret on a type name, click the Show Context Actions icon, and select Class Layout to open the layout in a separate window. Each debug profile now has a Configure Profile in .json action that opens the profile's configuration file in the editor. We've fixed an issue caused by recent PlatformIO updates that prevented CLion from loading the list of boards when creating a new PlatformIO project. The wizard now shows the boards instead of staying on Gathering info.... The Markdown preview now updates when a linked image file changes on disk. Please try this build, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
2026.3 eap build 263.6800.10 Released: 2026년 10월 8일 No subscription required Release notes	The latest CLion 2026.3 EAP build is out with the following highlights: Debug profiles are now stored in JSON format. CLion provides a JSON schema for `debug-profiles.json` at `IDE system dir/tmp/debug-profiles-schema.json`, along with completion and validation when editing the file. When a `requires` expression evaluates to `false`, the IDE now shows more detailed diagnostics explaining why the requirement is ill-formed. For example, it can show that a function is inaccessible, deleted, ambiguous, or unresolved. The new Inspect This action helps you quickly find relevant ways to analyze the code at the caret. Use ⌘⌥⇧A on macOS or Ctrl+Alt+Shift+A on Windows/Linux. Depending on the context, the popup gives you access to class layout, code issues, type hierarchy, or all these at once. The bundled CMake has been updated to v4.4.2. Please try this build, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
2026.3 eap build 263.6259.39 Released: 2026년 10월 2일 No subscription required Release notes	A new EAP build for CLion 2026.3 is now available. This update includes several important improvements and fixes. Give this build a try, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
2026.3 eap build 263.5701.36 Released: 2026년 9월 25일 No subscription required Release notes	The latest preview build for CLion 2026.3 includes mostly behind-the-scenes work and bug fixes. Try this build, share your feedback, and report any issues to our issue tracker.
2026.3 eap build 263.5153.33 Released: 2026년 9월 17일 No subscription required Release notes	A new EAP build for CLion 2026.3 EAP3 is now available. This update includes several important improvements and fixes. Give this build a try, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
2026.3 eap build 263.4732.7 Released: 2026년 9월 10일 No subscription required Release notes	The new CLion 2026.3 EAP build is now available with several enhancements. The key update is an improvement to the Profiles switcher in the main toolbar, making it easier to spot problems in the toolchain and debug configurations. A yellow warning icon now indicates when the selected build system or toolchain profile is incompatible with the selected debug profile. For example, a CMake profile that uses the system toolchain on macOS is incompatible with GDB, or a Docker toolchain is incompatible with a local debugger profile. The icon appears both on the switcher and next to the affected profile inside it. Hover over the warning icon to see a description of the issue. You can also open the profile settings directly from the switcher by clicking the gear icon. Give this build a try, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
2026.3 eap build 263.3889.68 Released: 2026년 9월 3일 No subscription required Release notes	The Early Access Program (EAP) for CLion 2026.3 has launched, and the first EAP build is now available. This build improves data breakpoints, also known as watchpoints, which are helpful when you need to focus on a specific variable and track its behavior as the program runs. Setting a data breakpoint is now much easier and no longer interrupts your debugging workflow. You can now: Set a data breakpoint from the Breakpoints dialog, as you would with regular breakpoints, or directly in the editor by right-clicking a variable. Add a data breakpoint using either a variable name or its address. Configure the same parameters available for regular breakpoints, such as conditions, hit counts, and detailed logging. Read our roadmap blog post to learn what else to expect from this EAP. Give this build a try, share your feedback, and report any issues to our issue tracker. Thank you for using CLion!
