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.

Sites are not browsable for non-admin users in Breadcrumb portlet when the site has Membership restricted or private.
The Default Layout permission was replaced with the current Group check.
Disable Group membership checking since it has no relationship to layout browsability.

All filtering in web content now only applies to the current folder. Previously, certain filters exhibited behavior limited to the current folder and now it has been standardized to all filters.

When we create a new Site the Allow Manual Membership Management option will be disabled by default to avoid uploading malicious files to the Documents and Media portlet.

The name of the reserved variable ID has always referred to the article ID so it has been changed to: Article ID. A new ID variable has been added that refers to the ID.

Searching after filtering will clear all existing filters and give a search from the entire data set.

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The Out-of-date feature, which allows publications to be labeled as “Out-of-date“ and prevents Users from publishing their content, is now off by default.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