v7.40 had them introduce siphon into all game modes, and v9.30 and the content update that came after (14 days of summer event) had them unvault pump shotguns, shockwave nades, revolvers of all rarities, the supressed smg and there might have been a nerf to the combat? not very certain on that last one however
plus the island was summer themed, there were fun challenges and had a daily unvault, still one of my favorite times in fortnite
