binary.h
[+] union protocol_binary_request_header 2

	Change	Effect
1	Field bytes has been added to this type.	Size of the union has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Type of field request has been changed from struct protocol_binary_request_header::._anon_6 (1 byte) to struct protocol_binary_request_header::._anon_7 (24 bytes).	1) This field may be incorrectly initialized or accessed by applications. 2) Size of the inclusive type has been changed.
