Breaking: #78222 - Extension autoload information is now in typo3conf/autoload

See forge#78222


To make clear that autoload information is not a cache, the files have been moved from typo3temp to typo3conf.


TYPO3 deployments which do not take advantage of composer, might need some adaption to also include the new location in typo3conf in the list of to be synced files.

Affected Installations

TYPO3 installation in non composer mode.


Class loading information can be re-dumped by

  • Activating or deactivating an extension
  • Running the dump command from the command line
  • In install tool (important actions)

The autoload files should never be deleted, but always only be re-dumped.
