Ehcache 2.x is no longer officially maintained by the Java community. Moved DXP internal caching to use Ehcache 3.10.8.
This means any existing ehcache configuration xml files won't be directly compatible and will likely cause errors or unexpected behavior in the new 3.x environment. Users will need to review and rewrite these configurations according to the new 3.x schema.
Release Notes
This section contains information about breaking changes in out-of-the-box DXP features and capabilities. For breaking changes or internal code, please check this link.
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.
