Pretty URL Configuration Check
Concrete now tests whether your web server supports pretty URLs before you enable them on the URLs and Redirection Dashboard page. If removing index.php from URLs could break rendering, a confirmation message now warns you before proceeding.

Behavioral Improvements

  • Enhanced Logging
    Additional logging has been added for pages, files, Express entries/objects, and calendar events.
  • More Efficient Version Cleanup
    The Remove Old Page Versions task is now optimized for large data sets and improved memory management. Previously, some sites with over 10,000 pages and multiple versions experienced halted tasks due to memory limits. This update handles large environments smoothly and completes reliably.
  • Smarter Redirects
    Trailing-slash redirects now occur only for GET requests, preventing unnecessary redirects for POST or other request types.
  • More Precise Log Timestamps
    Log entries now include seconds in their timestamps for better debugging accuracy.Logs-11-11-2025_12_16_PM.png

Bug Fixes

  • Fixed bug that prevented reordering Express entries under certain conditions.
  • Fixed issue preventing navigation to pages on other sites from the sitemap panel in multisite environments.
  • Fixed inability to retrieve group details through the REST API.
  • Fixed ClassNotFoundError when accessing the OpenAPI specification.
  • Fixed issue where page drafts could be created within the wrong site in multisite setups.
  • Fixed buggy Page List block pagination after upgrading to 9.4.5 under certain conditions.
  • Fixed tooltip visibility for the Image Block hover icon.

Miscellaneous

  • PHP 8 compatibility improvements and general code cleanup.
  • Several previously untranslatable strings are now translatable.
