Releases

Release Channels

Stable
2303.4.0
amd64

The Stable channel is intended for use in production clusters. Versions of Flatcar Container Linux have been tested as they move through Alpha and Beta channels before being promoted to stable.

Beta
2345.2.0
amd64

The Beta channel is where Flatcar Container Linux stability is solidified. We encourage including some beta machines in production clusters in order to catch any issues that may arise with your setup.

Alpha
2411.0.0
amd64 arm64

The Alpha channel follows a more frequent release cadence and is where new updates are introduced. Users can try the new versions of the Linux kernel, systemd and other core packages.

Edge
2411.99.0
amd64 arm64

The Edge channel includes experimental features and patches of the Linux kernel and other core OS packages. It is designed for experimental purposes and is not supported.
