The Arch Linux October ISO is available as release 2026.10.01. Published on October 1, 2026, the new installation snapshot uses Linux 7.2.7. It gives fresh installations a current starting point, while existing Arch systems continue to follow the rolling repositories.
What the Arch Linux October ISO contains
Arch’s official release record confirms the date, kernel version and x86_64 image filename. The download is about 1.5 GB. These details are useful when comparing a new image with an older USB installer you already have.
The snapshot label describes installation media, rather than a separate edition with its own support cycle. Arch publishes these images on a monthly cadence. As a result, the packages in a fresh image capture a particular moment, while repository updates continue after that date.
For someone installing on a spare machine, the October image reduces the distance between the initial environment and current packages. Nevertheless, a newer installer does not remove the need to check hardware support, backups and the intended disk layout.
Archinstall 4.5 brings practical refinements
The Archinstall project’s release notes list version 4.5, published on September 29. The changes include a fix for Wi-Fi network names containing spaces. That is a specific improvement worth noticing when a network fails to appear in the installer’s scan results.
Languages and session handling
The release also adds Norwegian Bokmål, Serbian and Vietnamese translations. In addition, it changes session handling for Hyprland, labwc, niri and sway from polkit to systemd-logind. Those are installer configuration changes, not a reason to assume every existing desktop needs manual intervention.
Other fixes cover locale names, disk-menu code and summary labels. The notes also add support for AArch64 bootloader and partition details. However, those upstream installer capabilities do not change the architecture of the standard x86_64 October ISO.
Existing users can skip the new download
Arch’s download page explicitly says existing users do not need a new ISO to update their systems. Therefore, reinstalling just to obtain the October label would add unnecessary work. Keep using the normal full-system update process and read relevant project notices.
For encrypted machines, a separate recent notice deserves attention: our report on mkinitcpio 42 and TPM2 LUKS re-enrollment explains an issue tied to that update. The new ISO announcement does not replace that guidance.
Before starting a fresh installation
- Use the official download page to choose a mirror or torrent.
- Compare the downloaded image with the published checksum and verify its signature.
- Keep a backup of important data before making changes to partitions.
- Confirm which drive will receive the installation before approving disk operations.
The Arch Linux October ISO offers current installation media with a clearly documented kernel baseline. For new users, the meaningful improvements are the fresh starting point and installer refinements. For existing users, the key distinction is simpler: a monthly image refresh does not require a reinstall.
