What Changed?

Previously, some Modification Conflicts and all Modification Deletion conflicts required manual resolution. These cases would show up in the Checking Changes screen, requiring manual user action to be resolved. They are now automatically resolved by overwriting production with the changes made in the publication and won't be displayed in the Checking Changes screen.

Why Was This Change Made?

The previous behavior required users to manually address many types of conflicts, which was usually a time-consuming effort. The new behavior reduces the friction in the publishing process while guaranteeing publications’ users they will be able to publish the needed modifications.

Who Is Affected?
All publication users are affected, but the focus is on the ones responsible for solving the conflicts and publishing the content.

How Should I Update My Features or Implementation to Better Adopt the Breaking Change?

Consider that now Publications’s users have more power to overwrite production changes. If you understand that the end-user scenario still requires human verification in Modification Deletion cases, the previous behavior can be restored by using the Modification Deletion Conflicts Toggle on Instance Settings > Publications.

Tag filter widget used to sort tags in alphabetical order but it seems customers expect to see the tags with more uses first. We think this change make sense so we have modified the behavior for this widget.

• Solution introduces 2 breaking changes in the data model, because of a “limitation” in the root model assumptions

  • There were 2 relationships connecting Data Set and Data Set Action depending on the type of action. Now there is only one

  • type field in Data Set Action object definition has changed. Now it stores the type of action (item, creation, bulk). The old type now goes to target field

• As a result, previously saved data set actions will not be manageable by DSM, neither fragment will find them.

In order to simplify the system processing of JSPs and improve performance, 2025.Q1 removes the optional configuration previously enabled by the property work.dir.override.enabled=true. JSPs will now always remain within the OSGi bundles that deploys them. This feature was already disabled by default due to the performance cost.

The Collection Page has been removed from the page administrator. An upgrade path substitutes the Collection Pages for Content Pages with a collection display without any functional change.

What Changed?
The Out-of-date feature, which allows publications to be labeled as “Out-of-date“ and prevents Users from publishing their content, is now off by default.

Why Was This Change Made?
The users still wanted to be able to publish publications created before Liferay upgrades, and now the conflict management improvements make this possible and safe.

Who Is Affected?
Users who have upgraded or plan to upgrade Liferay while having ongoing publications.

How should I update my features or implementation to better adopt the breaking change?
If needed, this feature can be enabled/disabled through the toggle on Instance Settings > Schema Version Check Enabled, which is off by default.

According to the deprecation feature flag pattern definition, the feature flag has been moved under Instance Setting.

The two separate configuration menus in the widgets of content page has been merged into a single menu.

Currently, when a user make a call to Batch in order to import any entity, the error returned has a different structure than a regular call to the Rest API. Specifically, the structure that is different is the one related to "failedItems" information.

With this change, users will have the same structured information no matter the endpoint they are using so matching errors and show it in the UI will be more simple.

The main change is:

Current structure:

"failedItems": [ 
{ "item": "{\"properties\": {\"field1\": 4, \"field2\": 5}}", 
  "itemIndex": 1, 
  "message": "com.liferay.portal.kernel.exception.ModelListenerException: com.liferay.object.exception.ObjectValidationRuleEngineException: Field 1 must be greater than,Field 2 must be greater than 5" } 
  ]

New structure:

"failedItems" : [ {
    "item" : "{\"properties\": {\"field1\": 4, \"field2\": 5}}",
    "itemIndex" : 1,
    "message" : "[{\"objectFieldName\":\"field1\",\"errorMessage\":\"Field 1 must be greater than\"},{\"objectFieldName\":\"field2\",\"errorMessage\":\"Field 2 must be greater than 5\"}]"
  } 
  ]

When performing a GET on text fields using the headless API and results in empty contents, the output returns ”” instead of being skipped. This change gives more flexibility to the users to decide what each user will do with the information.

Users should review all GET requests on text fields to adapt to this change.

Java 17 or 21 is already required for Portal runtime since 2024.Q2 release, but the source code was still able to be compiled on Java 8. With the 2025.Q1 release, Java 17 or 21 will also be required for compile.
