I am trying the new Warnings plugin 5.00 Public Beta as discussed in https://jenkins.io/blog/2018/09/11/speaker-blog-warnings-plugin/.

Having installed it, I notice that for Freestyle jobs the post build action has been renamed '(Deprecated) Scan for compiler warnings'.  I don't know which post build action to use instead.  Which should I now be using?

Could you make that clearer in the documentation?

Where is the main source of user documentation for this version of the plugin?
