Qt 6.10 Released
| Qt 6.10 is now available, bringing new features and improvements for developers and device creators. Highlights include a Flexbox layout for Qt Quick, expanded support for SVG and Lottie animations, and easier integration of C++ data into QML with new types like Tree Model and Synchronizer. Accessibility is improved with automatic high-contrast mode across platforms, and new APIs enhance productivity for both QML and C++ developers, whether building with Qt Quick or Qt Widgets. | | |
|
| | |  | Jesper talks to Maurice Kalinowski and Maycon Stamboroski from Qt Group about the Qt 6.10 features. Watch this interview. |

KDAB Tool Updates
| GammaRay lets developers inspect and analyze Qt applications at runtime, providing deep insight into object behavior and application state for debugging, performance tuning, and UI exploration. This release drops Qt 5 support (minimum Qt 6.5), adds LLVM MinGW support on Windows, resolves UI display issues, updates LZ4 to 1.10.0, and fixes Qt 6.10 build compatibility. Check out this blog for more details or the changelog for this new version. The new version of the framework, used for creating advanced docking systems in Qt applications, now defaults to Qt 6 with fixes for Qt 6.10 builds. QML can be used as a module or plugin without C++ code, and the release adds new APIs and other enhancements. More details about KDDockWidgets or the the full changelog.

Oxidize 2025 – The Time for Rust in Professional Projects?
| Interest in Rust continues to grow, especially among developers seeking safety, reliability, and strong interoperability with languages like C++. Yet many still wonder: is Rust ready for large-scale, professional use?
At Oxidize 2025, we saw compelling evidence that it is. The conference showcased real-world success stories - from automotive to robotics - highlighting how Rust is already powering safety-critical systems with certified toolchains. The talks and workshops demonstrated that Rust’s ecosystem has matured, offering measurable gains in developer productivity and software correctness.
