Updated Templates

• templates/course/lesson-navigation.php
• templates/course/lesson-preview.php
• templates/course/parent-course.php

New Features

• Added certificate global options for the default size of new certificates and certificate templates.

Updates and enhancements

• The site options lifterlms_certificate_bg_img_width,
  lifterlms_certificate_bg_img_height, and
  lifterlms_certificate_legacy_image_size are now used only for certificates
  and certificate templates created using the classic editor.
• The settings, found on the Engagements Settings screen, are hidden by default.

Bug Fixes

Updated Templates

• templates/certificates/content-legacy.php

This version is an unstable pre-release! We strongly advise against installing this in a production environment.

New Features

• The block editor is now enabled by default for certificates.
  • 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.

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.

Bug Fixes

• 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
