+Sumo Logic has used Java 8 for Installed Collectors until now. Since Java 8 reached end of public updates in January 2019 and newer versions offer better performance and security, we are upgrading Installed Collectors to use Java 17.
+
+If you're using a custom bundled JRE, ensure it's newer than Java 8. If not, upgrade to Java 17 or a more recent version.

 Deploying an upgrade to one or more collectors can be done through Sumo Logic. When you initiate a collector upgrade, the installed collector downloads the upgrade package directly from the Sumo Logic service. We recommend you follow our [best practices](#collector-upgrade-best-practices) when you upgrade your Collectors.
 
 You can also downgrade a collector to a previous version, as described in this topic.
