Version 6.12 of the Linux kernel has been released. The main feature consists of the merger of the real-time PREEMPT_RT scheduler, most likely one of the longest-running merger sagas in Linux' history. This means that Linux now fully supports both soft and hard real-time capabilities natively, which is a major step forward for the platform, especially when looking at embedded development. It's now no longer needed to draw in real-time support from outside the kernel.

Linux 6.12 also brings a huge number of improvements for graphics drivers, for both Intel and AMD's graphics cards. With 6.12, Linux now supports the Intel Xe2 integrated GPU as well as Intel's upcoming discrete "Battlemage" GPUs by default, and it contains more AMD RDNA4 support for those upcoming GPUs. DRM panics messages in 6.12 will show a QR code you can scan for more information, a feature written in Rust, and initial support for the Raspberry Pi 5 finally hit mainline too.

Of course, there's a lot more in here, like the usual LoongArch and ARM improvements, new drivers, and so on. and if you're a regular Linux user you'll see 6.12 make it to your distribution within a few weeks or months.
