Deprecation: #75625 - Deprecated cache clearing options 

See forge#75625

Description 

The following commands have been marked as deprecated and should not be used anymore:

  • Method DataHandler->clear_cacheCmd() with arguments system and temp_cached
  • userTSconfig setting options.clearCache.system
  • Option $TYPO3_CONF_VARS['SYS']['clearCacheSystem'] has been removed

Impact 

Directly or indirectly using method clear_cacheCmd with these arguments will trigger a deprecation log entry.

Affected Installations 

All installations with third party extensions using this method are affected.

Migration 

If the group of system caches needs to be deleted explicitly, use flushCachesInGroup('system') of CacheManager directly.
