Microsoft no longer supports Sharepoint versions 2010/2013. See SharePoint Server 2013 - Microsoft Lifecycle and Microsoft SharePoint Server 2010 - Microsoft Lifecycle.This feature has been in maintenance mode for a very long time and there is just a very small user base. Considering the high costs for us in terms of tests maintenance, we decided to deprecate it.

Style Books in Liferay are now explicitly tied to a specific theme at the moment of creation, using the frontend token definition provided by that theme (via OSGi or themeCSS client extension). This structural link now ensures that each Style Book can only operate within the boundaries of its associated theme, eliminating cross-theme token contamination and enforcing clearer theme-based design governance.

Key Benefits:

• Users can no longer save Style Books that accidentally combine tokens from different themes, avoiding visual inconsistencies and design regressions.

• Every Style Book now visibly shows which theme it belongs to, reducing errors and making it easier for teams to manage design assets across multiple sites.

• When applying a Style Book to a page, the system will only list those created with the same theme as the page’s current one—no more trial-and-error or guesswork.

• If a Style Book becomes incompatible with the applied theme (e.g., after a theme change), it will be automatically unlinked to prevent display issues.

• During platform upgrades, existing Style Books are automatically linked to the site’s current public theme (as defined in Site Builder > Pages > Options > Configuration), reducing manual cleanup work.

• If a Style Book is imported without a valid themeId, the user gets a clear warning and knows exactly what’s missing to fix the import.

• Style Books based on themes that are no longer deployed or no longer provide a valid frontend token definition are automatically marked as inactive—clearly flagged and non-selectable.

• The OSGi or themeCSS client extension ID is displayed for inactive Style Books, helping devs or admins identify which theme needs to be re-installed or fixed.

With the release of Liferay DXP 2025.Q2, we are deprecating the Elasticsearch 7 compatibility due to the end-of-maintenance and upcoming EOL of the Elastic Stack 7.17. Liferay strongly recommends all customers with 7.17.x or earlier deployments to upgrade to the latest compatible version of Elasticsearch 8.x. Learn more. 

Working with Global Services to identify pain points in Javascript resources distribution and unused code was the trigger to:

• Remove unused packages

• Deprecate old packages

• Set configurations to let users to not use/load some functionalities

• Create a JS size comparision report

• Create tooling to be able to split modules in smaller submodules
   

Key Benefits:

• Reduced total JS bundle size → Faster portal loading

• Reduced total exports → Faster portal loading

• Taking as example Masterclass home page:

  • Reduced JS Size in MB by 20%

  • Reduced number of request by 12 %

  • Mobile Lighthouse score from 52 to 56

  • Desktop Lighthouse score from 70 to 77

• Allow teams to divide modules to offer smaller entry points when they detect some part of the module is not commonly used.

• Size report tooling able to trigger risks.
