• Migration guide
  • Read the migration guide to upgrade from V8 to V9
• PSR-6
  • Upgraded psr/cache dependency to ^2.0||^3.0 (for PHP-8 types)
  • \Psr\Cache\CacheItemInterface::get() slightly changed to fully comply with missing PSR-6 specification: If the cache item is NOT hit, this method will return NULL.
• PSR-16
  • To be written when the PSR-16 will be upgraded for PHP-8
• API
  • Upgraded Phpfastcache API 4.0.0 (see changes)
  • Renamed Api::getPhpFastCacheVersion() to Api::getPhpfastcacheVersion()
  • Renamed Api::getPhpFastCacheChangelog() to Api::getPhpfastcacheChangelog()
  • Renamed Api::getPhpFastCacheGitHeadHash() to Api::getPhpfastcacheGitHeadHash()
• Cluster
  • Renamed \Phpfastcache\Cluster\AggregatorInterface::aggregateNewDriver() to \Phpfastcache\Cluster\AggregatorInterface::aggregateDriverByName()
• Exceptions
  • Added PhpfastcacheEventManagerException for EventManager-related exceptions
• Global
  • Removed magics methods from CacheManager CacheManager::DriverName(), use CacheManager::getInstance('DriverName') instead
  • \Phpfastcache\Proxy\PhpfastcacheAbstractProxy now implements \Phpfastcache\Proxy\PhpfastcacheAbstractProxyInterface
  • Slightly increased performances on some critical points of the library
  • Removed "BadPracticeOMeter" notice in CacheManager
  • Removed many code duplicate (like in \Phpfastcache\Driver\[DRIVER_NAME]\Item classes)
  • Reworked traits inter-dependencies for better logic and less polymorphic calls in pool/item traits
  • Upgrading library to use benefits of PHP 8 new features (see below)
  • Typed every class properties of the library
  • Migrated many Closure to arrow functions
  • Updated parameters & return type hint to use benefit of covariance and contravariance
  • Removed embedded Autoload, Phpfastcache is now only Composer-compatible.
  • Removed embedded dependencies (psr/cache, psr/simple-cache)
• Helpers
  • Deprecated \Phpfastcache\Helper\CacheConditionalHelper, use \Phpfastcache\CacheContract instead
  • The \Phpfastcache\CacheContract class is now also callable directly without calling get() method
• Config/Options
  • Configuration object will now be locked once the cache pool instance is running.
  • Updated ConfigurationOption which is no longer an ArrayObject class, therefore array-syntax is no longer available.
  • Removed configuration entry htaccess for files-based drivers.
  • Removed IOConfigurationOptionTrait::getHtaccess()
  • Removed IOConfigurationOptionTrait::setHtaccess()
• Tests
  • Added PHPMD, PHPCS and PHPSTAN coverages to increase quality of the project
  • Updated tests to work with new core/drivers changes
  • Removed Autoload test since its support has been removed and now only managed by Composer
  • Increased tests reliability and code coverage for better catching any eventual regression
• Item
  • \Psr\Cache\CacheItemInterface::set will not accept \Closure object anymore as method unique parameter
• Drivers
  • Added Arangodb driver support
  • Added Dynamodb (AWS) driver support
  • Added Firestore (GCP) driver support
  • Removed Cookie driver because of its potential dangerosity
  • Removed Couchbase (SDK 2 support dropped) driver which is now replaced by Couchbasev3 (SDK 3)
  • Removed Devtrue and Devfalse drivers
  • Added Devrandom with configurable factor chance and data length
  • Renamed classes \Phpfastcache\Cluster\Drivers\[STATEGY]\[CLUSTER_NAME]Cluster to \Phpfastcache\Cluster\Drivers\[STATEGY]\Driver for better driver naming across the project
• Events
  • Added \Phpfastcache\Event\EventReferenceParameter class and more events such as driver-specific events, see EVENTS.md file for more information
  • Event callbacks will now receive the eventName as an extra last callback parameter (except for onEveryEvents callbacks)
  • Added EventManagerInterface::on(array $eventNames, $callback) method, to subscribe to multiple events in once with the same callback
  • Added method named unbindAllEventCallbacks(): bool to EventManagerInterface to allow you to unbind/clear all event from an event instance
  • Updated argument type #2 ($items) of onCacheSaveMultipleItems() event from ExtendedCacheItemInterface[] to EventReferenceParameter($items)
  • Updated argument type #2 ($items) of onCacheCommitItem() event from ExtendedCacheItemInterface[] to EventReferenceParameter($items)
  • Updated argument type #2 ($value) of onCacheItemSet() event from mixed to EventReferenceParameter(mixed $value)
• Misc
  • Increased minimum PHP compatibility in composer to ^8.0
  • Updated copyright headers on every file to include the many project contributors
  • Globally renamed every occurrence of PhpFastCache to Phpcastcache
