[V7˖] Migrating your code to the V8
Because the V8 is relatively not backward compatible with the V7, here's a guide to help you to migrate your code:
As of the V8 the mandatory minimum php version has been increased to 7.3+. Once released, the php version 8.0 will be unit-tested
As of the V8 the "Auto" driver in CacheManager::getInstance() has been removed.
You will now be mandatory to specify the driver to use.
CacheManager::getInstance('Auto') or CacheManager::getInstance() expecting automatic driver chosen
Use CacheManager::getInstance('Files') or CacheManager::getInstance('Redis') or something else.
As of the V8 the "APC" has been removed. Use "APCu" instead.
CacheManager::getInstance('Apc')
CacheManager::getInstance('Apcu')
As of the V8 the "Xcache" has been removed, no replacement have been made.
It is completely abandoned (latest update: 2014)
Use alternative memory cache such as Redis, Memcache, Ssdb, etc.
CacheManager::getInstance('Apc')
CacheManager::getInstance('Apcu')
Check the CHANGELOG_API.md to see the changes.
As of the V8 the static I/O counter have been removed
Calling CacheManager::$ReadHits, CacheManager::$WriteHits
Replaced by\Phpfastcache\Entities\DriverIO callable in\Phpfastcache\Core\Pool\ExtendedCacheItemPoolInterface::getIO
As of the V8 the deprecated method CacheManager::setNamespacePath() have been removed.
Calling CacheManager::setNamespacePath('some\custom\path')
Replaced by cache manager "override" or "custom driver" features introduced in V7
As of the V8 the deprecated method CacheManager::getStaticSystemDrivers() have been removed.
Calling CacheManager::getStaticSystemDrivers()
Replaced by CacheManager::getDriverList()
The helper ActOnAll used to be useful to act on all instance
The "ActOnAll Helper" have been removed in profit of aggregated cluster support
The fallback features used to be useful when a backend failed to initialize
Use aggregated cluster Master/Slave instead
