We have released an update for Fortnite. Check out the full list of changes below:

• Implemented significant changes to Parties. These changes will be invisible to players in terms of how parties work, but joining and creating parties should now be more robust and stable. As always, if you experience any issues with joining or creating parties, please use the Feedback button to let us know!
• Fixed a potential crash which could occur when launching Fortnite on a Mac.
• Fixed an issue that could cause clients to disconnect when entering zones.
