NOTICE: Planned End of Updates, Joint Support, and Availability of the Zulu for Azure Distribution
Starting January 1, 2022, Microsoft and Azul will no longer provide updates or joint support services for
the Zulu for Azure OpenJDK-based distribution. While customers can use existing binaries in perpetuity,
quarterly bug fixes and security updates will end on December 31, 2021. In addition, access to binary
repositories and user download site for Zulu for Azure distribution may no longer be available after June
30, 2022. For more information, please visit Bruno Borges’ blog.
Zulu for Azure EE is verified compliant with the Java Standard Edition (“Java SE”) specifications using the
OpenJDK Community Technology Compatibility Kit (TCK). The TCK is a suite of more than 110,000 unit
tests which ensures that a binary build of OpenJDK meets all the specifications of the individual JSRs for
a given version of Java SE (e.g. Java 8).
Zulu for Azure EE is licensed identically to OpenJDK, which is under GPLv2 with Classpath Exception in
addition to other third party licenses.
Today, Zulu for Azure EE supports all Java LTS (Long Term Support) and MTS (Medium Term Support)
releases, including Java 7, 8 and 11 as well as Java 13 & 15. Bundles include JDKs, JREs, and Headless
JREs in zip, MSI, RPM, tar.gz, and DMG packages.

Yes, Azul’s OpenJDK committers do upstream changes back to the OpenJDK community. However,
upstreaming changes can take as much as 6 months before the project approves changes and fixes find
their way back into the OpenJDK community code base.
As a result of the strategic partnership with Azul Systems, Microsoft Azure-based Java developers will be
able to consume TCK tested builds of OpenJDK from multiple locations and in a variety of package types.
Microsoft Azure Support in conjunction with Azul, will provide support and updates for these binaries until
January 2021 (see NOTICE about). Azure Stack Java developers will not have to pay license or support
