7.4 Breaking Changes

Breaking changes break or significantly alter existing functionality or code structure. Here are all of the breaking changes for Liferay 7.4, starting with the latest quarterly release (2023 Q3). As the product changes and improves, we try our best to minimize these disruptions, but sometimes they are unavoidable.

Read about 7.4 breaking changes from before 2023 Q3 in the Liferay source code.

For breaking changes after Liferay 7.4, see Deprecations and Breaking Changes.

2023 Q4 Release

Changes in Liferay DXP

Here is a list of changes that break or significantly alter existing functionality within Liferay.

Breaking Change	Description	References
Minimum Compatible Elasticsearch Version	Elasticsearch must be updated to at least version 7.17. Liferay DXP no longer starts up with earlier versions (and a console error is shown).	Compatibility matrix
AB Testing	AB testing only supports one variant (in addition to the control). This prevents testing from taking exponentially longer time to complete.	LRAC-14353
Default Menu Display Configuration on Page Templates	By default, Menu Display widgets inherited from page templates have the Page Hierarchy configuration, even if private pages are enabled. This does not apply if the site has no pages.	LPS-194075
No Cache Option for DM File Downloads	By default, the new No Cache option is used for DM file downloads that do not have permission for Guest users.	LPS-174415
Support for Deploying Liferay with WebSphere	Deploying Liferay with an IBM WebSphere application server is deprecated. Support ends for this feature in one year (with the 2024 Q4 release).	TBA
Supported Java Versions	JDK 8 is deprecated and support for it ends in one year (with the 2024 Q4 release). Liferay DXP 7.4 must then use JDK 11.	TBA

2023 Q3 Release

Changes in Liferay DXP

Here is a list of changes that break or significantly alter existing functionality within Liferay.

Breaking Change	Description	References
Location of the Mark as Cacheable option for fragments	Mark (or unmark) fragments as cacheable in the Fragments menu (within the fragment’s Actions menu) instead of the editor. Now you can make this change separately from other edits to the fragment, which reduces the performance cost of propagating it to fragments in use. No implementation changes are necessary with this breaking change.	LPS-183735

Changes in Module Source Code

SolrClientManager.java modules/apps/portal-search-solr8/portal-search-solr8-impl/src/main/java/com/liferay/portal/search/solr8/internal/connection/SolrClientManager.java

Date: Jul. 4, 2023
Ticket: LPS-180691
What Changed: The SolrClientManager class’s extension points are removed.
Reason: Liferay no longer supports extending this class.

Date: Jul. 4, 2023
Ticket: LPS-180691
What Changed: The BASIC and CERT extension points are removed.
Reason: Liferay no longer supports these extension points.

Changes in `portal-impl` Classes

MessagingHotDeployListener.java portal-impl/src/com/liferay/portal/deploy/hot/MessagingHotDeployListener.java

Date: Aug. 4, 2023
Ticket: LPS-192680
What Changed: The MessagingHotDeployListener class is removed. The accompanying liferay/hot_deploy message bus destination is also removed. Instead, register a HotDeployListener to listen for hot deploy events.
Reason: The removed message bus destination is no longer used.

Date: Aug. 17, 2023
Ticket: LPS-193926
What Changed: The HookHotDeployListener class no longer supports deploying a DLProcessor via hook. Instead, convert your DLProcessor into an OSGi implementation.
Reason: This prevents duplicated logic to register DLProcessor implementations between DLProcessorRegistryImpl and HookHotDeployListener.

portal.properties portal-impl/src/portal.properties

Date: Sep. 4, 2023
Ticket: LPS-194379
What Changed: The portal property discussion.subscribe is removed. Instead, set the same configuration in your instance settings in the UI.
Reason: Instance settings can be set specifically per instance and while Liferay is running, so it’s more flexible to configure it as an instance setting.

HookHotDeployListener.java portal-impl/src/com/liferay/portal/deploy/hot/HookHotDeployListener.java

Date: Sep. 4, 2023
Ticket: LPS-194350
What Changed: The HookHotDeployListener class no longer supports deploying an external repository via hook. Instead, convert your own external repository implementation into an OSGi service.
Reason: OSGi services support more features than deploying external repositories via hook.

portal.properties portal-impl/src/portal.properties

Date: Sep. 13, 2023
Ticket: LPS-195006
What Changed: The portal property discussion.comments.always.editable.by.owner is removed. Instead, configure the same setting in your instance settings in the UI.
Reason: Instance settings can be set specifically per instance and while Liferay is running, so it’s more flexible to configure it as an instance setting.

Changes in `portal-kernel` Classes

Document.java portal-kernel/src/com/liferay/portal/kernel/search/Document.java

Date: Jul. 7, 2023
Ticket: LPS-188914
What Changed: These addFile methods are now deprecated: addFile(String, byte[], String), addFile(String, File, String), addFile(String, InputStream, String), and addFile(String, InputStream, String, int). Update your implementations by using an InputStream with the file’s data and calling the TextExtractor class’s extractText method. Then, call addFile(String, String) using the extractText call’s return value.
Reason: The deprecated addFile implementations are no longer used.

BaseModelPermissionChecker.java com.liferay.portal.kernel.security.permission.BaseModelPermissionChecker

Date: Aug. 24, 2023

Date: Sep. 5, 2023

TriggerConfiguration.java portal-kernel/src/com/liferay/portal/kernel/scheduler/TriggerConfiguration.java

Date: Sep. 11, 2023
Ticket: LPS-190994
What Changed: The scheduler framework no longer supports using an empty cron expression (or interval of 0) to disable a job. Instead, use the component blacklist to disable specific scheduler components. Check the required class names in the error message shown when using an empty cron expression.
Reason: If a job should not be bootstrapped, it should not be registered with the scheduler framework.
