Below is a non-exhaustive list of versions and their maintenance status:

??? example "Active Support / Security Support"

- **Active support**: Receives any bug fixes.

- **Security support**: Receives only critical bug and security fixes.

This page is maintained and updated periodically to reflect our roadmap and any decisions affecting the end of support for Traefik Proxy.

Please refer to our migration guides for specific instructions on upgrading between versions, an example is the v2 to v3 migration guide.

Versioning Scheme

The Traefik Proxy project follows the semantic versioning scheme and maintains a separate branch for each minor version. The main branch always represents the next upcoming minor or major version.

And these are our guiding rules for version support, as of Traefik v3.6:

• Every minor is supported for 6 months from its GA release date, which means several minor versions can be supported at the same time
• The last minor after releasing a new major is supported for 2 years following the major release (starting with v3)
• Previous rules are subject to change and in such cases an announcement will be made publicly, here is an example extending v1.x branch support.

!!! note "Versions released before v3.6"

These rules apply starting with Traefik v3.6. Before that, only the latest `minor` was on active support at any given time, and support for a `minor` ended as soon as the next one was released.
