Starting with JDK 9, Java SE standards promulgated by the JCP and the associated OpenJDK implementation establish new versioning nomenclature and a new release cadence for all Java releases, including Long Term Support (LTS) releases plus a new class of “feature” releases. General availability of LTS releases are scheduled every 3 years, with additional feature releases every six months.
Azul product releases align with Oracle’s and OpenJDK’s general availability for releases of Java SE. Azul customers have access to bug fixes, enhancements, and quarterly and emergency security updates.
Azul’s commercial product releases are designated with one of three different support lifecycles: Long Term Support (LTS), Medium Term Support (MTS), or Short Term Support (STS):
The table below details the class of support lifecycle for each existing and planned JDK release for Azul’s products, in addition to the expected availability of public updates and the lifecycle of Oracle’s commercial Java support offerings:

Azul offers community versions of Zulu, Azul’s certified builds of OpenJDK, for all releases of Java SE.

From time to time, Azul may offer “Feature Preview”, “Early Access” or “Not Supported” versions publicly or to select Azul customers. These releases are explicitly not supported in any manner.
