The consoles seem to get patches a little later than the PC with Fallout 4, but that's not a bad thing at all, it just means further time for refinement and optimizations. Right? This patch, 1.4 is a big one and it has a lot of changes, specifically those that'll help to add support for add-ons and mods that'll be coming later on.
The list of fixes and additions is quite long with more metal and wood door variants to choose from when looking to create the perfect settlement, more signs to put up to confuse yourself and others and more clutter. But the important part is the support for future mods, something that consoles haven't been able to enjoy as much as their PC brethren.
The long list of what the patch brings can be found right here, and we'll be updating this if there's anything specific to the consoles that isn't quite listed in that list.
