Now we follow a Symfony2-like naming convention for namespaces, interfaces and classes sticking with one clear rule. - Renamed namespaces: - Predis\Network - Predis\Profiles - Predis\Iterators - Predis\Options - Predis\Commands - Predis\Commands\Processors - Renamed interfaces: - Predis\IReplyObject - Predis\IRedisServerError - Predis\IConnectionFactory - Predis\IConnectionParameters - Predis\Options\IOption - Predis\Options\IClientOptions - Predis\Profile\IServerProfile - Predis\Pipeline\IPipelineExecutor - Predis\Distribution\INodeKeyGenerator - Predis\Distribution\IDistributionStrategy - Predis\Protocol\IProtocolProcessor - Predis\Protocol\IResponseReader - Predis\Protocol\IResponseHandler - Predis\Protocol\ICommandSerializer - Predis\Protocol\IComposableProtocolProcessor - Predis\Network\IConnection - Predis\Network\IConnectionSingle - Predis\Network\IConnectionComposable - Predis\Network\IConnectionCluster - Predis\Network\IConnectionReplication - Predis\Commands\ICommand - Predis\Commands\IPrefixable - Predis\Command\Processor\ICommandProcessor - Predis\Command\Processor\ICommandProcessorChain - Predis\Command\Processor\IProcessingSupport - Renamed Classes: - Predis\Commands\Command - Predis\Network\ConnectionBase - Classes moved to different namespaces: - Predis\MonitorContext Meh
