Linux 6.12 is the new long term supported kernel
Briefly

The latest release of the Linux kernel, 6.12, not only signifies a new long-term support version but also marks the end of the road for kernel 4.19.
Kernel 6.12 has introduced real-time operation capabilities after 20 years of development, allowing both hard and soft real-time behaviours to be enabled.
Enhancements to kernel 6.12 include the ability to display crash messages as QR codes, improving the debugging process for developers and users.
The Linux community faces a reduction in the number and lifespan of LTS kernels, with version 6.12 being supported until December 2026.
