This Extension optimizes the cache clearing behavior of TYPO3:

• When a content element is changed the cache of all pages is cleared where this content element is referenced by a shortcut.
• When a file or the metadata of a file is changed the cache of all pages is cleared where this file is used in the page properties or in content elements.
• When a file is changed the directory is detected and the cache of all pages is cleared where a folder collection references it.
• When a record of an Extension is changed the cache of all pages is cleared where a related plugin is used.
