The Linux 6.19 kernel development continues with the release of 6.19-rc4, following a quiet holiday period since earlier release candidates like rc1 in December 2025. The team is already planning for 6.19-rc8.
In the ongoing Linux 6.19 kernel series—first announced with rc1 by Linus Torvalds in December 2025—the latest 6.19-rc4 has been issued after a subdued holiday week with fewer contributions. This release candidate advances the iterative testing process toward the stable version expected in early 2026.
Kernel maintainers, as reported by Phoronix, are progressing efficiently despite the holiday lull. While specific changes in rc4 are not detailed, it builds on prior candidates that introduced features like Intel Xe3P graphics support, Rust drivers, and hardware enhancements for devices such as the AMD Steam Deck.
Release candidates like rc4 are essential for developers to identify and fix issues before finalization. The roadmap now eyes 6.19-rc8, aligning with the kernel's regular cadence of multiple RCs per cycle to deliver new drivers, security updates, and optimizations.
