CachyOS rebases to 7.3-rc5, drops six packages
By RepoJournal · composed from the cited sources · human-reviewed weekly · methodology
The month tracked Linux 7.3 from rc1 to rc5 while the stable 7.2 and 6.18 trees absorbed T2 Mac drivers and NVIDIA rebuilds.
CachyOS Linux 7.3-rc5-1 CachyOS/linux
The release candidate moved from 7.3-rc4 to rc5, the 7.3/xswap branch was removed, and 7.3/fixes picked up an mm/slub change that refills prefilled sheaves from the barn. This is where the 7.3 track is heading; if you run the rc kernels, rebase before the branch is trimmed back to fixes only.
CachyOS Linux 6.18.52-1 CachyOS/linux
The 6.18 LTS tree moved to 6.18.52 and the 6.18/amd-pstate and 6.18/sched-ext branches were removed while 6.18/t2 stayed. Users on 6.18 with sched-ext schedulers should confirm their configuration still matches what the tree applies.
CachyOS Linux 6.18.50-1 CachyOS/linux
CachyOS's 6.18 branch gained the t2bce driver stack and stopped applesmc from probing T2 MacBooks, alongside an upstream rebase from 6.18.48 to 6.18.50. Apple T2 hardware on this branch picks up the new driver stack without the old probe.
CachyOS Linux 7.2.5-1 CachyOS/linux
This release jumps from 7.2.3 to 7.2.5 upstream and drops the 7.2/t2 branch, folding the changes into 7.2/cachy, which now carries ADIOS 3.3.0 in iosched-7.2. The 7.2 line is the one to track if you are not running the 7.3 candidates.
profiles: match NVIDIA PRIME profiles on convertibles (#276) CachyOS/chwd
Chassis type 31 was missing from the laptop allowlist, so hybrid Intel plus NVIDIA convertibles were assigned the desktop profile, which writes the KMS config and produced a blank Plymouth and LUKS screen, per the issue it closes. Convertible owners who saw a blank unlock screen can update chwd.
fix(profiles): match NVIDIA PRIME profiles on convertibles CachyOS/chwd
The .prime NVIDIA profiles only matched DMI chassis types 8 to 11, so 2-in-1s landed on the desktop profile and its mkinitcpio KMS config. This is the underlying description of the same chassis-type-31 gap.
CachyOS Linux 7.2.7-1 CachyOS/linux
The 7.2 stable tree rebased to 7.2.7 and carries the 7.2/vesa-dsc-bpp branch with drm/edid parsing renames and VESA DSC work. It landed the same week Plymouth was reported drifting out of sync on LUKS unlock.
Delete cef-minimal-obs-bin directory due to being outdated CachyOS/cachyos-aur-derived
The cef-minimal-obs-bin directory was deleted from cachyos-aur-derived for being outdated, resolving the linked distribution issue. Anyone building OBS from that AUR-derived package needs a different source.
