This is a bug-fix releases addressing a couple of issues in specific corner cases:
- PHP emitted
E_WARNnotices when an early error occurred while creating the underlying socket, such as trying to use a non-existent or inaccessible UNIX domain socket file or when the TCP/IP stack is running out of resources (e.g. port exhaustion). - Commands queued during the connect() operation were discarded by the client because the underlying socket was being set as readable as soon as the connection was fully established even if the buffer was not empty.
