Fedora Linux 43 Release Candidate 1.4 released
A new release candidate for Fedora Linux 43 is now available for testing and validation. This milestone is a very important step toward the final release of Fedora 43. It's very important that people in the community take part in the testing process.
One of the most important changes in Fedora 43 is the addition of different desktop environments, each with its own set of features and improvements. For example, the Fedora COSMIC Spin has hybrid per-workspace tiling management, window stacks with tabs for switching between windows, and the ability to customize things using the GTK toolkit. XFCE 4.20 has also been updated to add experimental Wayland support, which should make things work better and faster.
LXQt 2.1 is another important update. It now uses Wayland by default via miriway. This integration makes it possible for this lightweight desktop environment and Fedora Linux to work together flawlessly. Furthermore, the Fedora KDE Plasma Desktop has been promoted to full Edition status, ensuring that users can take advantage of the latest version of this popular desktop environment.
Fedora 43 has a lot of new features that are great for developers, in addition to the ones already mentioned. NASA made the Copilot Runtime Verification Framework, which makes it possible to write hard real-time C code. This framework helps developers make apps that are faster and more reliable. Ruby 3.4 has a new default parser (Prism), better performance for the YJIT compiler, and the Happy Eyeballs Version 2 socket feature, which makes it a good choice for Ruby developers.
The PHP 8.4 update adds property hooks for computed properties, independent read/write scope control, a new #[Deprecated] attribute, and new array functions, making it even more powerful as a popular programming language. GCC 15, Binutils 2.44, glibc 2.41, and GDB 15+ are also new in the GNU Toolchain. This feature makes sure that developers have access to the newest tools and technologies.
Fedora Linux 43 Beta also includes the FEX Emulator, a powerful emulator that lets you run x86 and x86-64 binaries on an AArch64 Linux host. This makes it easy for developers to test their apps. The switch from SDL 2 to SDL 3 is also in the works, with the goal of making the switch as smooth as possible and possibly improving performance.
Community members need to take part in release validation testing to make sure that Fedora 43 is of high quality. Fedora 43 Candidate RC-1.4 is now ready for testing, and users are asked to help finish all the necessary validation testing.
