In the October 1 release notes for version 42.30, Epic outlined the character dialogue template, unarmed carryables, and analytics benchmarks in the Creator Portal.
The template helps authors connect conversations with game actions. Analytics allows you to compare the island's performance with a group of similar projects. Separately, it was reported that the islands on the Rocket Racing templates have been removed from publication, and the tools have been moved to create races without the old template. This applies to copyright islands; Vehicle Locker is retained. To change the project, first read the official transfer instructions.
