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.

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.

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\"}]"
  } 
  ]

The deployFast Gradle task gave developers a way to hot deploy compiled JSPs into the Liferay bundle work folder as a way to reduce the deployment time of OSGi bundles. However, the speed improvements it gave were insignificant and it also depended on underlying system functionality that allowed overriding JSPs in the Liferay work directory, which has been removed.
