Error: Diff module is loaded before node module

I have 5.0 (not RC) with several modules. Just added diff (5.x-1.0) and after enabling the module I get the error from the status report:

Diff module diff index: 14 - node index: 21

Diff module is loaded before node module. The diff module needs to be loaded after the node module to overwrite the menu entry for revisions. Change the weight of the diff module to a value higher than the node module's weight

I know that node is core but I'm not sure how to change the index.
