Elastic Stack version 7.9.2 was released, featuring various fixes and enhancements, and users are encouraged to upgrade. The update includes a known issue with Elasticsearch on older Linux operating systems, as Elasticsearch 7.9.2 comes with JDK 15, which requires glibc 2.14. This version is not available on older systems like Oracle Enterprise Linux 6, RedHat Enterprise Linux 6, and CentOS 6, thus making the bundled JDK unsupported. In response, Elasticsearch 7.9.2 will automatically detect the absence of glibc 2.14 and will use JAVA_HOME to find the suitable Java runtime for these systems, requiring users to ensure JAVA_HOME is properly configured. For comprehensive updates, users should consult the release notes for each Elastic Stack product, including Elasticsearch, Kibana, Logstash, Elastic Enterprise Search, Elastic Observability, and Elastic APM.
