Linux kernel 7.0 RC1 has been released, featuring routine updates primarily focused on drivers and architecture tweaks, which may improve stability for newer hardware but could also introduce issues for legacy devices. Developers working with Rust will find improvements to Rust bindings, while users are advised to monitor log files post-installation for any regressions, particularly if utilizing custom modules or legacy drivers. A safe testing approach includes using git to download the kernel, keeping existing configurations, and conducting dry boots in QEMU before applying changes to real hardware. Overall, while the update is generally painless for most users, those with niche drivers or custom setups should consider waiting for RC2 to avoid potential issues

Linux kernel 7.0 RC1 has been released, with Linus Torvalds describing it as "routine" updates that touch drivers and architecture tweaks. While the new driver updates may improve stability on newer hardware, they could also introduce regressions in legacy devices, and users should keep an eye on log files after installation. Developers working on kernel modules in Rust will be interested to note improvements to the Rust bindings for VFS and various drivers. For most users, installing Linux kernel 7.0 RC1 is likely to be painless, but those with custom hardware or development builds may want to wait until RC2 lands to ensure stability.
