Arch Linux (/ɑːrtʃ/) is an open source, rolling release Linux distribution. Arch Linux is kept up-to-date by regularly updating the individual pieces of software that it comprises. Arch Linux is intentionally minimal, and is meant to be configured by the user during installation so they may add only what they require.
Arch Linux provides monthly "snapshots" which are used as installation media. The newest snapshot as of December 8, 2025, is 2025.12.01, featuring Linux kernel 6.17.9.
