This feature allows the user to require that a field's values be unique inside of that column. When this is configured, the system will not let two records have the same value for that field, behaving similarly to a key to that entry.

Evolving the extensibility of system objects through objects framework, this feature allows users to create and update System Object entries through Object Actions as they can with Custom Objects.

This feature adds read-only support for all object fields types, making sure users are not able to update those fields from both the UI or APIs, only the system can: through default values or actions, for example.

This feature adds a new field type “Date and Time”. A Datetime value stores a year, month, day, time, and time zone. With this field, users will also be able to create time ranges, manage priorities and order entries well, and to give more context and assertiveness to the data.

This feature empowers users to create content use cases on top of objects framework, allowing admins to enable localization for objects' entries text fields.

This feature allows the user to define a default value for object picklist fields. Default Value can be configured for custom fields from both Custom and System Objects.

This feature allows power users to configure the intervals to retry to send the email notifications when the first instant attempt fails.

Operating Liferay (on-prem!) with Elasticsearch 8 as a search engine leveraging its REST API compatibility mode through the bundled Elasticsearch 7 connector allowing Liferay deployments to upgrade the Elastic Stack to 8.x (opt-in), while also keeping compatibility with 7.x.

General Upgrade Instructions:

Please refer to the documentation for more details.

1. No action is required for deployments already using and insisting to stay on Elasticsearch 7.
2. Moving to Elasticsearch 8 may require a full reindex depending on the choice of the upgrade path:
   1. Upgrading the current Elasticsearch 7.x cluster to 8.x and connect DXP (Upgrade Elasticsearch | Elasticsearch Guide [8.10] | Elastic , recommended) → No reindex required
   2. Setting-up a new Elasticsearch 8.x cluster, connect DXP → Reindex required!

This is not a new connector, but enhancements to the existing bundled Elasticsearch 7 connector and other Elasticsearch-only features (like Commerce, Workflow Metrics or Search Tuning) leveraging the REST API compatibility mode of Elasticsearch 8 servers.

Support for Object displays pages in the search results, aggregating (via Custom Facet widget), filtering (Custom Filter widget) and sorting (Sort widget) using Object fields that are indexed as Nested Fields in Elasticsearch, similar to Web Content Structure (DDM) fields.

Publications can take up quite a bit of space in the database.  While some users need an extensive history, others do not.

With this new feature we can provide an optional clean up to remove older publications for those who do not need the history.

Liferay Portal 7.4 CE GA78 and Liferay DXP 7.4 Update 78 Tomcat Bundles and Docker Images come with Elasticsearch 7.17.10 for Sidecar.

We have refactored Ongoing, Scheduled and History tabs to use dataset display, and added a configuration to speed up review changes screen.

With this new feature an admin should be able to help preconfigure a publication to help facilitate their unique workflows.

Publication templates can be leveraged to provide naming patterns to any created publication. Tokens are provided to allow each publication to have unique names.

Admins can also assign roles to users immediately during publication creation.

Users can now create, edit, or delete knowledge base articles within a publication.

This new feature allows content editors to view the only publications that included modifications to a particular asset.

Users can preview the changes of a wiki page within a publication.

This feature introduces the ability to create and manage custom picklists for product specifications. Users can now define specific values for product attributes, improving data consistency and efficiency. The feature includes the option to create new picklists or add existing ones directly on the specification page.

Roles Managers can now define permissions for Object entries directly within the Roles UI. A new “Objects” main menu item has been added to the Define Permissions tab, listing all Custom Objects, allowing easier granular permission assignment.

Enhance your checkout experience by offering customers accurate UPS shipping costs based on their order details. Easily integrate this feature into your online store with our client extension available for purchase on the Marketplace.

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.
