Overview of major distribution updates and improvements.

Fedora released a stable version of Fedora Linux 40, providing different versions of the distribution, as well as Live builds with different desktop environments. The distribution is available for the x86_64, Power64, and ARM64 (AArch64) architectures. Noted a delay in the Fedora Silverblue release.

1. Major updates include:
Fedora Workstation has updated the GNOME desktop to version 46, adding global search, improved performance of the file manager and terminal emulators, experimental VRR (Variable Refresh Rate) support, improved output at fractional zoom, better connectivity to external services, an updated configurator and notification system, and a new rendering engine based on the Vulkan API. for GTK.

2. Fedora KDE migrated to the KDE 6 release using Wayland, ending support for X11-based sessions, although a return is possible through the installation of the plasma-workspace-x11 package. Using XWayland allows you to run X11 applications in Wayland-based sessions.
3. The Fedora project combined atomically updated distributions under the new Atomic Desktops brand, retaining the names Fedora Silverblue, Fedora Kinoite, Fedora CoreOS, and Fedora IoT, as well as introducing new Fedora Sway Atomic and Fedora Budgie Atomic builds.
4. Updates include LLVM 18, GCC 14, binutils 2.41, glibc 2.39, gdb 14.1, PHP 8.3, Ruby 3.3, Go 1.22, Java 21, AMD ROCm 6, Boost 1.83, 389 Directory Server 3.0.0, Podman 5, PostgreSQL 16, TBB 2021.8, SQLAlchemy 2, Kubernetes 1.29.
5. By default, NetworkManager activates the IPv4 address conflict detection mechanism by sending a valid ARP packet before assigning an address, and assigns a separate permanent MAC address for wireless connections.
6. OpenSSL 1.1 and python3.7 were removed, Passim switched to GDBM, PyTorch machine learning package was added to the repository, and Kubernetes packages were restructured.
7. A new UKI boot system has been implemented, allowing you to check the integrity and validity of the kernel and initrd when booting via UEFI, providing improved security and simplifying the boot process.
