Contour Support Policy

This document describes which versions of Contour are supported by the Contour team.

Supported releases

Contour supports a single release track at a time. New releases are made on-demand rather than following a fixed schedule.

When a new release is published, the previous release is no longer supported. For example, when Contour 1.34 is released, Contour 1.33 will no longer be supported.

What does a release being “supported” mean?

In short, “supported” means that Contour will issue fixes for security and other critical bugs for that release’s supported lifetime.

However, the project will require users to upgrade to the most recent patch release for a version to be supported. So, if Contour 1.20.0 is the only supported version, and Contour 1.20.1 is released, then the supported version will change to 1.20.1.

Latest version and the :latest tag

The latest stable release is identified by the Docker tag :latest. :latest is an alias for 1.33 which is the current stable release.

:latest is always guaranteed to point to the highest available :<major>.<minor>.<patch> release. When a new :<major>.<minor> release track is out the :latest tag will move along.

For example, prior to a patch release version Contour 1.20.0 was the :latest stable release. If Contour 1.20.1 is released, the :latest tag will move to that version.
