J.E. Sawyer's Fallout: New Vegas Mod Updated to V4

There are not a whole lot of changes in the v4 update to Obsidian's J.E. Sawyer's personal Fallout: New Vegas mod, but I'm sure that people who have been playing with it so far will still be interested in the latest version of the overhaul mod designed by the title's own project director and lead designer. Without further ado, here's the changelog:
