2.0.0 Beta 4

• Updated interfaces extending ClosableStream (which was renamed to Closable in amphp/byte-stream) to include the onClose method which was added to the interface.

• SocketAddress has been changed to an interface with two implementations - InternetAddress and UnixAddress. These can be differentiated using SocketAddress::getType(), which returns an enum SocketAddressType with cases Unix and Internet.

• SocketAddress static constructors have been relocated as functions in the Amp\Socket\SocketAddress namespace.

• DnsSocketConnector now tries each host returned from a DNS query a single time before failing. Retrying the list is accomplished through a new connector implementation, RetrySocketConnector that can be configured to retry a given number of times with an exponential backoff between attempts.

• Max attempts has been removed from ConnectContext in favor of a constructor parameter to RetrySocketConnector.

• Added SocketServerFactory interface for creating SocketServer instances, along with an implementation ResourceSocketServerFactory.

• EncryptableSocket::getTlsState() now returns an enum TlsState with cases corresponding to the prior constants defined in EncryptableSocket, which have been removed.
