What shipped: CachyOS Linux 6.18.48-1 and 6.18.48-2 shipped as breaking updates [1][2], with 7.3-rc1-1 and 7.3-rc1-2 also landing [3][4]. "Add initial patches" for 7.3 are under development [5], and the kernel-patches repo includes "nvidia: Fix skill issue" [6], noting the NVIDIA work is in progress. The chwd profile matcher gained a fix to match NVIDIA PRIME profiles on convertibles [7][8]. Also: sudo-rs 0.2.15-1 shipped [9], and mesa-git dropped vdpau dependency as part of automated updates.

Why it matters: The 6.18.48-2 breaking change is labeled breaking, so verify your setup before upgrading, especially if you rely on the existing kernel configuration. The chwd fix directly affects NVIDIA PRIME users on convertible laptops, making profile matching work correctly on those systems [7][8]. The 7.3-rc1 kernels are release candidates, not stable, so expect further changes as the NVIDIA "skill issue" patches are finalized [6].

What's next: With 7.3-rc1 merged and initial patches added [5], the rc series is underway; track "fix skill issue" [6] and the convertible PRIME chwd change [7] as they move toward stable. The removal of the outdated cef-minimal-obs-bin directory [10] and the kernel wiki statement on the removed Propeller statement [11] are housekeeping, not user-facing changes.

Also: Other packaged updates included zen-browser-bin 1.21.16b [12], faugus-launcher 2.2.1 [13], protonplus 0.6.5 [14], waypaper 2.9 [15], and Chromium 152 and Teams for Linux led the day's package updates; China Mirror status checks returned healthy [16][17].
