   Linux 7.4-rc1 Sets Record for Largest Kernel Merge Window

   Linus Torvalds released Linux 7.4-rc1 on November 1, 2026, following the largest merge window in the kernel's history. The window included nearly 20,000 commits, specifically 19,671, far exceeding the typical historical range of 13,000 to 14,000. Torvalds attributes this surge largely to AI-generated work, stating the kernel is out of its stabilization phase and using a much healthier model for AI contributions. The release includes performance improvements, AMDGPU HDMI 2.1 defaults, and preparations for AMD Ryzen Zen 6.

   Why it matters

   The kernel source tree has grown to 41,605,120 lines. This massive influx of patches reflects a shift in how AI is integrated into core development. It also suggests a potential push for a future Long Term Support release.
