+
+### Major Version Support
+
+We follow the rule to support the previous major version for
+- 24 months of `active support` (includes new features and bugfixes) and
+- 36 months of `security support`
+after the release of a new major version.
+
+E.g. [CakePHP 5.0](https://github.com/cakephp/cakephp/releases/tag/5.0.0) released on September 10th 2023,
+so we will support CakePHP 4.x until September 10th 2025 and provide security updates until September 10th 2026.
+
+### Minor Version Support
+
+`Active support` for a minor branch ends the moment a new minor branch is released.
+E.g. when CakePHP 4.2 is released, active support for CakePHP 4.1 will end and only security updates will be provided.
+
+`Security updates` will be provided
+- till the end of the support period for the major version, or
+- 3 new minor releases have been published (e.g. `4.2` support ended when `4.5` was released)
+
+whichever comes first.
+
+> [!TIP]
+> Keep production applications on a currently supported major line and plan
+> regular upgrades to stay within supported minor ranges.
+
+> [!TIP]
+> Each minor and major release of CakePHP includes automated upgrade commands which you
+> can use to upgrade your application or plugin. See e.g. the
+> [upgrade guide](../appendices/4-0-upgrade-guide.md#use-the-upgrade-tool)
+> for more details on how to use these commands.
