Fortnite v.43 patch update will be happening in a few hours from now, accompanied with a server down time.
There are a number of things we can expect from this patch, and they are quite the big changes. Some of the possible things they are gonna include are:
Playground, a Limited Time mode that will load players into the Battle Royale map, but with more time to roam around the map. There will be more available resources, all the treasure chests and ammo crates will be spawned, and squad friendly fire will be enabled, but players can respawn immediately when killed. Challenge Progress Notifications, starting in v4.3 there will be in-match pop ups to highlight your challenge progress.
