 - `435f69c` **feat: Steam's System settings: the OS name stays CachyOS (no renaming, also not in About this System), Steamify <version> as the variant, the SteamOS release it follows as the codename (steamos-3.9)**
 - `ce71b34` **feat: Steam's System settings and About this System like on SteamOS: OS name "CachyOS with Steamify" (lsb-release, kept through CachyOS updates by a pacman hook), Steamify as OS variant and version (os-release VARIANT/VERSION_ID; NAME/PRETTY_NAME stay CachyOS's for limine, TARGET_OS_NAME pinned), "CachyOS Linux with Steamify" in About this System; on a Steam Machine the serial number and Steam's Wi-Fi backend setting (existing installs get it as an update)**
 - `07a94cd` **fix(ui): The progress screen's ✓ and ! stand upright: only a dot on the circle spins while a step runs (they kept the spinner's last angle)**
