Linux 7.4 has recorded the largest merge window in kernel history, with nearly 20,000 commits during its initial development phase. The previous version, Linux 7.3, logged 16,267 commits during the same period—a significant gap that highlights accelerating development velocity.
The surge appears tied to increased adoption of AI tools in kernel development. The merge window, a roughly two-week phase at the start of each Linux release cycle, focuses on integrating new features, drivers, and improvements. This period of intense activity sets the foundation for the entire release.
The jump from 7.3 to 7.4 suggests that AI-assisted coding tools are helping developers contribute at a faster pace, whether through code generation, testing, or optimization. As AI tools mature and become embedded in development workflows, we may see this trend continue in future kernel cycles.
