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 AMD Loader has been removed. Liferay DXP officially supports ESM, which is the official standardized module system for JavaScript, while AMD was a third-party solution. By adopting ESM, products align with the language's native capabilities and future direction. Modern browsers now natively support ESM, allowing for direct use without transpilation or additional loaders. This can lead to reduced bundle sizes, faster initial page loads and simplified development workflows.

Users who are using amd-loader must migrate to the Liferay.loader. See link for more details.
