Content Blocks as Site Set 

Site sets are a feature introduced with TYPO3 v13. They allow to manage dependencies on a per site basis. These dependencies may contain site settings, TypoScript or page TSconfig.

Content Blocks adds an integration into this dependency management system by adding each loaded Content Block as a Site Set. By doing so, it is now possible to require different Content Blocks for each site in your installation. On top of this, auto-loading for TypoScript and page TSconfig is added, just like for normal Site Set definitions.
