From version 1.x to version 2.0

In version 2.0 the compatibility with TYPO3 v9 LTS was removed. Also PHP 7.4 or higher is necessary.


The signal/slots were removed:

  • registerAdditionalTypeProperties
  • shouldEmbedMarkup

You can migrate the slots easily to the PSR-14 event listeners:

Previous slot (in ext_localconf.php):

$signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(

PSR-14 event listener (in Configuration/Services.yaml):

         - name: event.listener
           identifier: 'myAdditionalPropertiesForPerson'
           event: Brotkrueml\Schema\Event\RegisterAdditionalTypePropertiesEvent

You can find more information about the PSR-14 event listeners in the chapter PSR-14 events.

Removed Deprecations

The following deprecated methods and classes were removed:

  • Brotkrueml\Schema\Core\Model\AbstractType->isEmpty()
  • Brotkrueml\Schema\Manager\SchemaManager->setMainEntityOfWebPage()
  • Brotkrueml\Schema\Provider\TypesProvider

For the migration of the SchemaManager->setMainEntityOfWebPage() method call a Rector exists. For the other two follow the instructions on the deprecations chapter.

Markup is embedded by default on “noindex” pages

In schema version 1.x the markup was not embedded on “noindex” pages (with installed SEO system extension). In version 2 the markup is embedded by default also on these pages. You can deactivate this behaviour in the extension configuration.

Also in version 1.x a PSR-14 event Brotkrueml\Schema\Event\ShouldEmbedMarkupEvent was available to change the default behaviour of not embedding the markup on “noindex” pages. With the new configuration option this is not necessary anymore and event listeners for this event must be removed.
