Breaking: #67646 - PHP library inclusion in frontend removed

See Issue #67646

Description

The PHP library inclusion into the TYPO3 Frontend has been removed without substitution. Previously it was used to include plain PHP scripts during the Frontend request.

The method PageGenerator::getIncFiles() has been removed.

Impact

The TypoScript options config.includeLibrary and config.includeLibs have no effect anymore. Any calls to PageGenerator::getIncFiles() will result in a fatal error.

Affected Installations

Any installation using the TypoScript options named above. Any third party code using the method named above.

Migration

Use hooks during the Frontend set up to execute custom PHP code.
