-The plugin works best with sbt >= 0.13.6. See the [compatibility notes](#compatibility-notes) to use this plugin with an older version of sbt.

-## Compatibility notes
-
- * sbt < 0.13.6: The plugin will fall back on the old ivy report XML backend which suffers from [#39].

- * sbt <= 0.12.x: Old versions of sbt are not actively supported any more. Please use the old version from the [0.7 branch](https://github.com/jrudolph/sbt-dependency-graph/tree/0.7).
