Breaking: #73514 - TypoScript property "includeLibs" removed

See Issue #73514

Description

The TypoScript property to load additional PHP libraries via .includeLibs has been removed from the Content Objects COA/COA_INT and USER/USER_INT.

Impact

Setting the .includeLibs property will have no effect anymore.

Affected Installations

Any installation using a very old pi_based extension that does not ship proper class naming or autoloading information.

Migration

Make sure everything that was previously loaded via includeLibs is now encapsulated in proper PHP classes, which is referenced by USER/USER_INT when needed.
