Breaking: #76802 - Drop xcache cache backend¶
xcache core cache backend has been dropped because PHP7 does no longer support xcache.
Instances will throw an exception or a fatal error using a cache with this backend configured.
Instances that still use a configuration in
'SYS' => [ 'caching' => [ 'cacheConfigurations' => [ 'aCache' => [ 'backend' => 'TYPO3\\CMS\\Core\\Cache\\Backend\\XcacheBackend',
Affected instances must switch to a different cache backend,
PHP module with
provides the same local server in memory characteristics like
xcache and should be considered as alternative.
