Per Elastic’s product lifecycle, Elasticsearch 7.17.x versions are supported and maintained until Elasticsearch version 9 is released. While Elastic does not provide specific release dates for future releases, for Elasticsearch 9.0.0, the new release is anticipated in early calendar year 2025.

Therefore, Liferay strongly recommends all customers with 7.17.x deployments to begin the planning phase for an upgrade project to the latest compatible Elasticsearch 8.x version.

Compatibility with Elasticsearch 8 is available on 7.4 U81+. → Operating Liferay 7.4 GA/Update 81+ with Elasticsearch 8 - Liferay

Note: The Elasticsearch 8.x compatibility is provided through the bundled Elasticsearch 7 connector and the REST API Compatibility of Elasticsearch 8.

Liferay ships with an updated Elasticsearch connector using 7.17.21 as the client version and also as version of Sidecar Elasticsearch server for development and testing purposes.

Clause Contributors configuration is now stored within the blueprint’s JSON with a smaller footprint, reducing the size of a blueprint by more than 90% when using the default setting (all contributors enabled → Enable All) or the new Disable All option.

The behavior of the different options is as follows:

• with Enable All, all current and future query clause contributors introduced to the platform will be enabled automatically. Disable All behaves the opposite way,

• with Customize, the configuration is locked to the specified contributor list.

The selection filters of the Data Set Manager has been revamped to allow chosing different type of sources. On top of the picklist, now the admin user may select an API Headless as filter values source, so the filter values might be populated with the values coming from the API response. This allow users to have a more automated process on the filter creation.

Data Set Manager lets from now to map Array structures, so a given cell of a Data Set can show list of values, for example to list the roles of a user or the tags of a product.
