LifterLMS Version 6.0.0

This major release of LifterLMS focuses on improving the experience of creating, designing, and managing achievements and certificates: use the block editor to design certificates, sync awards with their templates, award achievements and certificates on demand without requiring an engagement trigger, and much more. In addition, this release removes a significant number of previously deprecated classes, methods, and functions. Please read the full Breaking Changes sections for more information on removed code.

New Features
  • 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 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 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 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.
  • Added a link to return to the student dashboard when viewing an awarded certificate. #1959
  • Provide additional information to hooks on the student single course reporting screen.
Updates and Enhancements
  • 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 will automatically be used for legacy certificates and can be forced by filtering llms_use_legacy_engagement_images. #1081
  • 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 achievements and certificates dashboard endpoints are now paginated. #669
  • Added pagination to achievement and certificate reporting pages.
  • 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 template 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
  • 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
  • The coupon code in the student’s order details table is now wrapped in a <code> tag instead of an <a> tag. #2033
  • Updates LifterLMS REST to v1.0.0-beta.23.
  • Updated LifterLMS Blocks to version 2.4.0.
Bug Fixes
  • Delayed engagements are automatically unscheduled when the related post is deleted.
  • A disabled student dashboard endpoint will no longer display the endpoint’s summary on the main dashboard page. #535
  • 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
  • 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.
  • Fixed the label hover on picture type quizzes in some themes. #2015
Database Migration
Deprecations
  • Public access to properties of the abstract LLMS_Database_Query has been deprecated.
  • Public access to class property LLMS_Database_Query::$found_results. The property is no longer publicly writable but can be read via LLMS_Database_Query::get_found_results().
