Some upgrade processes may not consider the ctColectionId column which may generate inconsistencies for customers using Publications, especially for older versions.

Add changeTrackingEnabled to the standard rest-config.yaml so that services must specify Publications support. This will simplify the process of enabling change tracking for future Headless APIs.

We introduced a new feature to streamline workflows with 1:1 relationships between objects! Now, users can create and update nested objects directly from the primary object's CRUD views, and enjoy seamless delete and view operations translated from the Data Set Manager (DSM). This update makes managing data smoother and more efficient.

Allow users to map Repeatable fields of a Web Content Structure already defined in Fragments and Collection Displays.

The /search and /suggestions APIs comes with the following enhancements:

• New, optional scope parameter supporting Site (Group) IDs and External Reference Codes (ERCs) in /search. The scope parameter of /suggestions has also been updated to have the same semantics.

• /search now is in RELEASE status.

• The APIs now are available under the /o/search/v1.0/ endpoint with backward compatibility for current /o/portal-search-rest/v1.0 calls through server-side forward.

Refer to the documentation for more details.

Elasticsearch 8.15.x has been tested and added to the compatibility matrix to the corresponding Liferay versions.

Note: Compatibility with newer Elasticsearch minor versions is tested in two ways:

1. Latest-Latest: Testing the latest Liferay version with the latest available minor version of Elasticsearch → e.g. Master/2024.Q3 + Elasticsearch 8.15

2. Minimum-Latest: Testing the minimum Liferay version where Elasticsearch 8 compatibility was first made available with the latest minor version of Elasticsearch → DXP 7.4 U81/DXP 7.3 U31 + Elasticsearch 8.15

This way Liferay can allow a broader deployment base to operate their stack with an up-to-date search engine version.

As Elasticsearch is usually releases a new Minor version roughly every two months, this is a recurring process and a planed activity in each quarter.

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.
