June 2025: Type System and Modernization

We're excited to announce a major new release of x64dbg, the open-source user mode debugger for Windows. For those new to the project, x64dbg is designed to make reverse engineering and malware analysis faster and more intuitive. This release marks a significant step forward, overhauling our core type system and modernizing our entire toolchain to bring you a more powerful and stable debugging experience.

NOTE: There were some minor issues that made the 2025.06.30 snapshot unusable (signing issue causing a Windows Defender false positive, AVX-512 support crashed in x32dbg and the VC runtime was not loaded correctly). Because of this that snapshot has been deleted and a fixed one has been put here.

✨ Revamped Type System

In previous versions, analyzing data structures was a tedious, manual process and many features were not supported. This release adds support for bitfields, enums and anonymous types, which allows all types in the Windows SDK to be represented and displayed.

The ManyTypes plugin by @notpidgey (who also drove this revamp) allows you to import C header files and see the results directly in x64dbg. While we plan to streamline this workflow even further in future updates, this is a huge leap in making data inspection easier.

This isn't just about convenience; it's about speed. We've introduced drastic performance improvements to the struct widget, so you can now browse deeply nested pointers and large data structures without the lag.

We’ve also added a host of quality-of-life improvements:

Interactive type selection: While selecting the type you will instantly see what the data looks like, enabling a more interactive workflow.
Smarter Displays: Character arrays are now automatically rendered as strings, saving you an extra step.
Better Integration: You can now invoke the "Display type" action directly from the register and stack views, making it easier than ever to inspect data on the fly.

💻 AVX-512 and Half-Float Support

This release introduces support for the latest CPU instruction sets, ensuring you can analyze even the most modern applications.

AVX-512 Support: You now have the power to debug and analyze code that leverages the AVX-512 instruction set, a critical feature for high-performance computing and complex malware.
Half-Float Support: We've added support for 16-bit half-precision floating-point numbers in the dump, a feature especially useful when reversing graphics applications or machine learning models.

⚡ Small Changes, Big Impact

Sometimes it’s the little things that count. Based on your feedback, we've added several small but mighty workflow enhancements:

Copy Graph Image: You can now copy the function graph directly to your clipboard, making it effortless to share your findings or add visuals to your reports.
Copy Calling Convention Arguments: A new context menu option lets you quickly copy function arguments, streamlining the process of reconstructing code or documenting function calls.
Focus on Window in Handles View: You can now bring a target window to the foreground directly from the handles view, which is incredibly useful for UI-heavy debugging.
Revamped Launcher: The launcher now has checkboxes and an uninstall option.

🚀 Modern Tooling and a New Release Cycle

We've completed a monumental migration of our entire build system to Visual Studio 2022 and CMake. This massive undertaking provides a more stable foundation, makes it easier for new developers to contribute, and accelerates the pace of future improvements. The compilation instructions were cut down from 13 steps to a single one.

There has also been movement on a headless version of x64dbg. The main focus for now is automated testing, but eventually it will be expanded to allow headless automations.

Starting with this release, we will be using CalVer (Calendar Versioning) with proper GitHub releases and tags. This will keep our releases more organized and allow package managers and users to reference specific versions more easily. Additionally Windows XP is no longer supported and for Windows 7/8.1 you will get an unskippable deprecation warning:

🔮 Looking Ahead: A Cross-Platform Future

We're excited to share a glimpse into our experimental cross-platform branch. This is our testbed for separating core GUI widgets into a reusable library, with the goal of bringing x64dbg's powerful tools to all major platforms (Windows, macOS, and Linux).

Current experimental tools include:

A simple hex viewer that uses the ImHex Pattern Language to visualize data structures.
A minidump viewer to browse .dmp files on any platform.
A remote table tool that showcases fetching data over a high-latency network.

These tools are still in early development and not part of the release, but they represent a critical step toward a more versatile and platform-independent future for our components.
