AdminConditionsAndActions - Where in the "upgrade docs"?

I’m testing out 4.4.2 in my lab system upgrading from 4.4.1. We were using the AdminConditionsAndActions plugin prior to 4.4.2. When I run the upgrade scripts, it tells me I need to reference the “upgrade documentation” for what to do if I was using the plugin. I’ve checked here:

And in the README docs available in the release file but I must be overlooking something. Where is it dicussed about what to do if you had the plug in prior? I removed it from the Plugins directive and so far everything looks OK but I need to be sure that’s all I have to do.
