+ *
+ * Design limitations:
+ *  - Max 4 billion cache keys per cache tag as limited by Redis Set datatype.
+ *    E.g. If you use a "all" items tag for expiry instead of clear(), that limits you to 4 billion cache items also.

+CHANGELOG
+=========
+
+4.4.0
+-----
+
+ * added support for connecting to Redis Sentinel clusters
+ * added argument `$prefix` to `AdapterInterface::clear()`
+ * improved `RedisTagAwareAdapter` to support Redis server >= 2.8 and up to 4B items per tag
+ * added `TagAwareMarshaller` for optimized data storage when using `AbstractTagAwareAdapter`
+ * added `DeflateMarshaller` to compress serialized values
+ * removed support for phpredis 4 `compression`
+ * [BC BREAK] `RedisTagAwareAdapter` is not compatible with `RedisCluster` from `Predis` anymore, use `phpredis` instead
+ * Marked the `CacheDataCollector` class as `@final`.
+
+4.3.0
+-----
+
+ * removed `psr/simple-cache` dependency, run `composer require psr/simple-cache` if you need it
+ * deprecated all PSR-16 adapters, use `Psr16Cache` or `Symfony\Contracts\Cache\CacheInterface` implementations instead
+ * deprecated `SimpleCacheAdapter`, use `Psr16Adapter` instead
+
+4.2.0
+-----
+
+ * added support for connecting to Redis clusters via DSN
+ * added support for configuring multiple Memcached servers via DSN
+ * added `MarshallerInterface` and `DefaultMarshaller` to allow changing the serializer and provide one that automatically uses igbinary when available
+ * implemented `CacheInterface`, which provides stampede protection via probabilistic early expiration and should become the preferred way to use a cache
+ * added sub-second expiry accuracy for backends that support it
+ * added support for phpredis 4 `compression` and `tcp_keepalive` options
+ * added automatic table creation when using Doctrine DBAL with PDO-based backends
+ * throw `LogicException` when `CacheItem::tag()` is called on an item coming from a non tag-aware pool
+ * deprecated `CacheItem::getPreviousTags()`, use `CacheItem::getMetadata()` instead
+ * deprecated the `AbstractAdapter::unserialize()` and `AbstractCache::unserialize()` methods
+ * added `CacheCollectorPass` (originally in `FrameworkBundle`)
+ * added `CachePoolClearerPass` (originally in `FrameworkBundle`)
+ * added `CachePoolPass` (originally in `FrameworkBundle`)
+ * added `CachePoolPrunerPass` (originally in `FrameworkBundle`)
+
+3.4.0
+-----
+
+ * added using options from Memcached DSN
+ * added PruneableInterface so PSR-6 or PSR-16 cache implementations can declare support for manual stale cache pruning
+ * added prune logic to FilesystemTrait, PhpFilesTrait, PdoTrait, TagAwareAdapter and ChainTrait
+ * now FilesystemAdapter, PhpFilesAdapter, FilesystemCache, PhpFilesCache, PdoAdapter, PdoCache, ChainAdapter, and
+   ChainCache implement PruneableInterface and support manual stale cache pruning
+
+3.3.0
+-----
+
+ * added CacheItem::getPreviousTags() to get bound tags coming from the pool storage if any
+ * added PSR-16 "Simple Cache" implementations for all existing PSR-6 adapters
+ * added Psr6Cache and SimpleCacheAdapter for bidirectional interoperability between PSR-6 and PSR-16
+ * added MemcachedAdapter (PSR-6) and MemcachedCache (PSR-16)
+ * added TraceableAdapter (PSR-6) and TraceableCache (PSR-16)
+
+3.2.0
+-----
+
+ * added TagAwareAdapter for tags-based invalidation
+ * added PdoAdapter with PDO and Doctrine DBAL support
+ * added PhpArrayAdapter and PhpFilesAdapter for OPcache-backed shared memory storage (PHP 7+ only)
+ * added NullAdapter
+
+3.1.0
+-----
+
+ * added the component with strict PSR-6 implementations
+ * added ApcuAdapter, ArrayAdapter, FilesystemAdapter and RedisAdapter
+ * added AbstractAdapter, ChainAdapter and ProxyAdapter

+Symfony PSR-6 implementation for caching
+========================================
+
+This component provides an extended [PSR-6](http://www.php-fig.org/psr/psr-6/)
+implementation for adding cache to your applications. It is designed to have a
+low overhead so that caching is fastest. It ships with a few caching adapters
+for the most widespread and suited to caching backends. It also provides a
+`doctrine/cache` proxy adapter to cover more advanced caching needs and a proxy
+adapter for greater interoperability between PSR-6 implementations.

+CHANGELOG
+=========
+
+4.4.0
+-----
+
+ * deprecated finding hidden commands using an abbreviation, use the full name instead
+ * added `Question::setTrimmable` default to true to allow the answer to be trimmed
+ * added method `minSecondsBetweenRedraws()` and `maxSecondsBetweenRedraws()` on `ProgressBar`
+ * `Application` implements `ResetInterface`
+ * marked all dispatched event classes as `@final`
+ * added support for displaying table horizontally
+ * deprecated returning `null` from `Command::execute()`, return `0` instead
+ * Deprecated the `Application::renderException()` and `Application::doRenderException()` methods,
+   use `renderThrowable()` and `doRenderThrowable()` instead.
+ * added support for the `NO_COLOR` env var (https://no-color.org/)
+
+4.3.0
+-----
+
+ * added support for hyperlinks
+ * added `ProgressBar::iterate()` method that simplify updating the progress bar when iterating
+ * added `Question::setAutocompleterCallback()` to provide a callback function
+   that dynamically generates suggestions as the user types
+
+4.2.0
+-----
+
+ * allowed passing commands as `[$process, 'ENV_VAR' => 'value']` to
+   `ProcessHelper::run()` to pass environment variables
+ * deprecated passing a command as a string to `ProcessHelper::run()`,
+   pass it the command as an array of its arguments instead
+ * made the `ProcessHelper` class final
+ * added `WrappableOutputFormatterInterface::formatAndWrap()` (implemented in `OutputFormatter`)
+ * added `capture_stderr_separately` option to `CommandTester::execute()`
+
+4.1.0
+-----
+
+ * added option to run suggested command if command is not found and only 1 alternative is available
+ * added option to modify console output and print multiple modifiable sections
+ * added support for iterable messages in output `write` and `writeln` methods
+
+4.0.0
+-----

+
+ * added `SHELL_VERBOSITY` env var to control verbosity
+ * added `CommandLoaderInterface`, `FactoryCommandLoader` and PSR-11
+   `ContainerCommandLoader` for commands lazy-loading
+ * added a case-insensitive command name matching fallback
+ * added static `Command::$defaultName/getDefaultName()`, allowing for
+   commands to be registered at compile time in the application command loader.
+   Setting the `$defaultName` property avoids the need for filling the `command`
+   attribute on the `console.command` tag when using `AddConsoleCommandPass`.
+
+3.3.0
+-----
+
+* added `ExceptionListener`
+* added `AddConsoleCommandPass` (originally in FrameworkBundle)
