Breaking: #73514 - TypoScript property “includeLibs” removed¶
See Issue #73514
The TypoScript property to load additional PHP libraries via
.includeLibs has been removed from the Content
.includeLibs property will have no effect anymore.
Any installation using a very old pi_based extension that does not ship proper class naming or autoloading information.
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.
