IBM Semeru Runtimes builds are available for LTS as well as non-LTS JDK releases, but only LTS builds are supported.

The LTS release cadence is currently one release every 2 years, supported until the upstream OpenJDK maintenance ends (at least 2 years, but usually much more). Security updates and bug fixes are released quarterly.

IBM Semeru Runtimes is one of the many builds of OpenJDK. For recommendations on which JDK build to use, check out whichjdk.com.

More information is available on the IBM Semeru Runtime website.
