Release Model
How each Linux distribution ships and schedules updates.
Ubuntu
Ships regular releases every six months, with a Long Term Support (LTS) release every two years that receives several years of security updates, making LTS the default choice for production use.
Debian
Follows a slow, stability-focused fixed-release cycle (roughly every two years) through a well-defined unstable → testing → stable pipeline, with packages only promoted once they’ve proven reliable.
Fedora
Ships a new numbered release roughly every six months, with each release supported for about a year, moving faster than Ubuntu LTS or Debian stable to stay close to upstream software versions.
Arch Linux
Uses a rolling-release model with no version numbers — packages update continuously and there’s no separate “upgrade to the next release” step, just ongoing incremental updates.
openSUSE
Offers two parallel release models: Leap, a traditional fixed-point release aligned with SUSE Linux Enterprise, and Tumbleweed, a fully rolling release with continuously updated packages.
Linux Mint
Bases its main edition on Ubuntu’s LTS releases, inheriting that multi-year support window, and layers its own update cadence for desktop-specific packages on top.
Alpine Linux
Ships fixed releases roughly every six months, each supported for about two years, with a strong emphasis on small, frequent security patches for its minimal package set.
NixOS
Offers both a stable release channel (updated roughly every six months) and an unstable rolling channel, with the added ability to atomically roll the entire system back to any previous configuration generation.
