Did this introduce a change to break Asset Termination Logs? I see this now when I try to start 4.0.1: ```auto The website encountered an unexpected error. Try again later. Error: Undefined constant Drupal\log\Event\LogEvent::PRESAVE in Drupal\farm_asset_termination\EventSubscriber\LogEventSubscriber::getSubscribedEvents() (line 35 of sites/all/modules/farmos/farm_asset_termination/src/EventSubscriber/LogEventSubscriber.php). Drupal\farm_asset_termination\EventSubscriber\LogEventSubscriber::getSubscribedEvents() (Line: 234) Symfony\Component\EventDispatcher\DependencyInjection\ExtractingEventDispatcher::getSubscribedEvents() (Line: 162) Symfony\Component\EventDispatcher\EventDispatcher->addSubscriber() (Line: 157) Symfony\Component\EventDispatcher\DependencyInjection\RegisterListenersPass->process() (Line: 29) Drupal\Core\DependencyInjection\Compiler\RegisterEventSubscribersPass->process() (Line: 73) Symfony\Component\DependencyInjection\Compiler\Compiler->compile() (Line: 820) Symfony\Component\DependencyInjection\ContainerBuilder->compile() (Line: 1532) Drupal\Core\DrupalKernel->compileContainer() (Line: 1032) Drupal\Core\DrupalKernel->initializeContainer() (Line: 524) Drupal\Core\DrupalKernel->boot() (Line: 743) Drupal\Core\DrupalKernel->handle() (Line: 19) ``` If I go back to 4.0.0, the site loads without the error. Thanks for all the work! Troy ---

Oops I think you’re right @tlcarpenter69… this might require a 4.0.2 release to fix… I’ll take a look… ---

Actually, I’m going to open a merge request to fix this in the Asset Termination module… ---

Where would I see the merge request so I can track when there’s a new version of the plugin? ---
