LifterLMS Version 4.0.0

This is a major release. Many backwards incompatible changes have been made that may affect your site if you have custom code which rely on previously deprecated functions or methods. If you’re not sure about your custom code, test the upgrade in a staging site.

Bug Fixes
  • Fixed an issue encountered during quiz grading.
  • Add RTL language support for popover interfaces found throughout the course builder.
  • Fixed issue encountered in MySQL 8.0 when using the bbPress integration.
LifterLMS REST API 1.0.0-beta.13
  • Bugfix: Fixed error response messages on the instructors endpoint.
  • Bugfix: Fixed student progress deletion endpoint issues preventing progress from being fully removed.
Action Scheduler Library

Switches from prospress/action-scheduler to woocommerce/action-scheduler. The repository has been moved but it’s the same library & upgrades to latest version (3.1.6).

While this is a semantically major upgrade of the library there are no backwards incompatible changes to the public API.

There have been several deprecated functions/classes. The LifterLMS core does not directly use any of these deprecated functions but 3rd parties might and should review the changelog of the library to see if they are affected by any deprecations: https://github.com/woocommerce/action-scheduler/releases.

Deprecations
  • Function LLMS() is deprecated in favor of llms().
Templates Modified
  • templates/global/form-login.php
  • templates/global/form-registration.php
Miscellaneous Breaking Changes

WP Session Manager Library

Removes the bundled WP Session Manager plugin dependency, all public methods included with this plugin have been removed without direct replacements.

Removed JS dependencies

Removes bundled JS bootstrap 3 dependencies: “collapse” and “transition”

Removed CSS Classes

Removes classnames from student dashboard login and registration form wrapper elements which conflict with bootstrap causing visual issues.

These classes are not used by the LifterLMS core or add-ons and are a legacy class that hasn’t been removed for fear of creating backwards compatibility issues with any custom css, 3rd party themes, etc…

  • templates/global/form-login.php: Removes col-1 class from the div.llms-person-login-form-wrapper element.
  • templates/global/form-registration.php: : Removes col-2 class from the div.llms-new-person-form-wrapper element.

Removed SVG assets and functionality

  • LifterLMS no longer utilizes SVGs powered by the LLMS_Svg class. The class has been deprecated and removed (see below).
  • The assets/svg directory (and all SVG assets contained within) has been removed.
  • The constant LLMS_SVG_DIR has been removed.
