Liferay Tomcat Bundles and Docker Images ship with Elasticsearch 8.18 as the sidecar search engine.
Benefits
The Elasticsearch server runtime included in Liferay DXP Tomcat Bundles and Docker Images (aka. Sidecar Elasticsearch, located under [Liferay-Home]/elasticsearch-sidecar) is provided as a convenience for local development and testing only. It is neither suitable nor supported for production.
With this release, the Liferay DXP is now built with the modern, cloud native technology provided by the Jakarta EE 10 platform. The legacy Java EE platform will no longer be supported on this and future releases, allowing Liferay DXP to continue to evolve and build innovative solutions to meet your business needs.
Benefits
Liferay DXP now certified on Jakarta-based application servers: Tomcat 10.1, Jboss EAP 8.0, and Wildfly 30. This also provides support for newer specifications such as Portlet 4.0, Servlet 6.0, and Spring Framework 6.0. The update paves the way for faster feature development and rapid security fixes available in the modern Java enterprise ecosystem.
