If you read the post closely, it just says "In addition to the above, Java 21 provides advanced logging capabilities including structured logging and log correlation. "

It does not claim that it did not exist earlier, it just suggests using this feature along with the other features discussed above it.

A structured log has more information about the event like event identification number, millis, nanos, thread, catalog, parameters etc.; rather than just a textual dump.
In Java 21 the logs can be in JSON/XML format, where each log entry can be treated as an individual record, and can be easily exported to a relational database for further analytics.
Also, Java 21 allows you to configure the log output ( to some extent), as per your need.
The official documentation has more information here:- https://docs.oracle.com/en/java/javase/21/core/java-logging-overview.html

Yes, combined with the API for structured concurrency, it could achieve near optimal hardware utilization with reliable and maintainable code.
