The Backdrop community is proud to release version 1.31 of Backdrop CMS, following our 4-month release cycle.

Notes for updating

  • No changes were made to settings.php, .htaccess, or robots.txt files in this release. Updating customized versions of those files is not necessary.
  • The database update script at /core/update.php does not need to be run.

Important: As a prerequisite to supporting PHP 8.4, Backdrop CMS dropped support for PHP 5.6 and PHP 7.0. You must ensure your server is running a newer version of PHP before updating. We recommend PHP 8.3 for the time being as contributed modules may take some time to support 8.4. See the blog post on this change.

Changes since version 1.30.3 are listed below.

New features

  • Allow Image Styles to be used with inline images with CKEditor #2658
  • Provide CKEditor 5 Emoji integration #6772
  • Allow attaching libraries, js, css with hook_theme. #6859

Bug fixes

  • Selecting another image while keeping image style can lead to wrong dimensions #6896
  • Width and height do not get reset when uploading a new inline image #6895

Version Updates

  • PHP 8.4 Support #6777
  • Update CKEditor5 to version 44.3.0 #6788
