Client awareness level:
This is a value used by revision 4 servers to add functionality but keep backwards compatibility. Fields marked with awl: 1 in this documentation require the client to send this message with Client awareness level set to
0x01 for them to be received in server to client messages.
0x00: awl of 0 (default).
0x01: awl of 1.
Clients should continue to parse assuming an old awl until they receive this message as confirmation of their requested change.
