Change logs are for internal use, they have just shown it to us. They have implemented it at the moment in the current build they are using. They just haven't released it to us yet. You are just plain wrong on this fact.
Also to be honest the current climate in Ukraine (they are based in Kiev) means it may not be released for weeks, and that would be fine. They could have family in danger this very moment we don't know. Their mental health and lives trump our wants for a video game or an update at the moment. So give them a break ffs.
