I mean, it’s telling you to update the Address Library mod. If Fallout 4 gets an update, it may take them a bit, but they should roll it out.

That thing is required to know where in memory other mods need to fiddle to do stuff outside of the APIs that Bethesda provides, so it’s extremely dependent on the version of Fallout 4 — basically, it being updated means that all the other mods can rely on it knowing what the relevant addresses are and don’t have to be update itself. If Fallout 4 gets updated, you’re probably going to need to update it.
