+## Support Phases
+
+Express major versions go through three support phases:
+
+- `CURRENT`: A new major version is designated as `CURRENT` upon release. It is available but not the `latest` tag on npm for a minimum of 3 months. It receives all types of active work: bug fixes, security patches, new features, and deprecation notices.
+- `ACTIVE`: After the minimum 3 month period, once the Technical Committee agrees it is stable and secure, the version is tagged `latest` on npm for a minimum of 12 months. `ACTIVE` lines receive all types of active work and are considered the most stable and well supported version at any given time.
+- `MAINTENANCE`: When a new major version becomes `ACTIVE`, the previous major version enters `MAINTENANCE` for 12 months. `MAINTENANCE` lines only receive security patches or high priority bug fixes, so users are highly encouraged to upgrade to a `CURRENT` or `ACTIVE` release.
+
+v4 is a special case, having been the only major version for most of the history of Node.js itself, and its `MAINTENANCE` period may be extended. For any other release line, the end dates are not determined until the next major version is released, since that is what starts the clock on its `MAINTENANCE` period. Consider these dates goals, not commitments.
+
+These support periods also extend to the packages maintained under the [expressjs](https://github.com/expressjs), [jshttp](https://github.com/jshttp), and [pillarjs](https://github.com/pillarjs) organizations: the versions that a supported Express release line depends on are supported for at least as long as that line, and their support may be extended beyond that at the team's discretion.
