 and Uber [Kraken](https://github.com/uber/kraken) (v0.1.3+) into Harbor and allow users to define policies around this action.

+Please note that due to some historical reasons, there are two versions of Dragonfly,
+[v1](https://github.com/dragonflyoss/Dragonfly) and [v2](https://github.com/dragonflyoss/Dragonfly2),
+and v1 has been archived and is no longer maintained, and v2 has a complete refactoring of v1, so v2 is not compatible with v1,
+the following is the version-compatible relationship between Harbor and Dragonfly, and it is recommended that you upgrade to the latest version of Dragonfly.
