Important: #90371 - TypoScript option config.content_from_pid_allowOutsideDomain removed

See Issue #90371

Description

TYPO3’s Site Handling - introduced in TYPO3 v9 - allows defining multiple sites within one installation, whereas before all configuration was based on domain records. The TypoScript option config.content_from_pid_allowOutsideDomain was used to limit the page property option “Show content from this page instead” (pages.content_from_pid) to be evaluated outside of the current page tree which was ineffective since the usage of Site Handling.

The option serves no purpose anymore and has been removed.
