New Features

• Added a link to return to the student dashboard when viewing an awarded certificate. #1959
• The block editor is now enabled by default for certificates when using WordPress versions 5.8 and later.
• Existing certificates are marked as “legacy” and will continue to use the classic editor until migrated.
• To migrate a certificate, click the “Migrate Certificate” button. This will force the certificate’s content into blocks.
• A number of new settings are available to certificates when using the block editor:
• Set the certificate’s display (and print) size using common paper sizes such as US Letter, US Legal, A3, A4, and more.
• Set the certificate’s display orientation: portrait of landscape.
• Set the certificate’s inner margins.
• Set the certificate’s background color.
• A new block, the Certificate Title Block, has been made available to certificates.
• The block works like a WordPress core Heading Block with added options for selecting from a few display fonts (provided by Google Web Fonts).
• The block controls the title of awarded certificates.
• + Added the ability to sync awarded certificates with the template used to generate them. #1078
• The post_name of earned certificate posts will be generated with a randomized 3+ character string in favor of relying on sequential numbers.
• Added the ability for administrators and LMS managers to edit earned certificates/achievements from the students reporting screen, as well as award new certificates/achievements to students.
• + Added certificate global options for the default size of new certificates and certificate templates.
• Certificate and email template merge code buttons now include [llms-user] information shortcodes.
• Added certificate sequential ID functionality merge code. Read more.

Updates and Enhancements

• Added pagination to achievement and certificate reporting pages.
• Certificates no longer use the header.php and footer.php files from the site’s theme, instead custom templates (templates/certificates/header.php and templates/certificates/footer.php) are used instead. These templates are minimal and exclude theme wrappers which reduces the visual conflicts encountered from theme wrappers, backgrounds, and more, especially when printing certificates. #463
• The achivements and certificates dashboard endpoints are now paginated. #669
• Added new default images for use with achievements and certificates.
• The site-wide default images can be customized on the admin panel under Settings -> Engagements.
• The old default images can be used by filtering llms_use_legacy_engagement_images. #1081
• The URL of earned user certificates has been changed from “my_certificate” to “certificate”. Requests to the old url are automatically redirected to the new url, including instances where the URL slug has been translated.
• The URL of certificate temaplate previews has been changed from “certificate” to “certificate-template”.
• The certificate merge code, {first_name}, now outputs an empty string in favor of falling back to the user’s nickname when there is no first name for the user. #1640
• Updates LifterLMS REST to v1.0.0-beta.22.
• The look and behavior of the certificate {{MINI_CERTIFICATE}} pop-over notification merge code now displays a placeholder preview of the certificate in favor of attempting to render a tiny version of the actual certificate. #1950

Bug Fixes

• + Fixed how the protected LLMS_Notifications_Query::$found_results property is accessed in LLMS_Abstract_Notification_Controller::has_subscriber_received(). + Fixed how the protected LLMS_Notifications_Query::$max_pages property is accessed in lifterlms_template_student_dashboard_my_notifications().
• Delayed engagements are automatically unscheduled when the related post is deleted.
• Prior to sending a delayed engagement the recipient’s enrollment in the related post is verified resulting the engagement not being triggered if the recipient’s enrollment has been terminated. #290
• A disabled student dashboard endpoint will no longer display the endpoint’s summary on the main dashboard page. #535
• Post search filter boxes on various post tables will now longer display a link to the selected post.
• Basic notification code is no longer loaded on the admin panel.
