Since the release of Java 9, both Java SE Platform and the JDK went from the historical feature-driven release model to a strict, time-based model with a new feature release every six months, update releases every quarter and a long-term support release every three years. 

Java 12 was released in March 2019 but, according to JVM Ecosystem Report 2018, most users are still developing in Java versions 7 & 8. The need to migrate may come sooner than later, and thus being up to date with the latest features becomes a pressing issue.
