memcached.h
[+] struct memcached_server_st (1)

	Change	Effect
1	Field sockaddr_inited has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Low Severity (2)

memcached.h
[+] enum memcached_return (1)

	Change	Effect
1	Name of member with value 2 has been changed from MEMCACHED_HOST_LOCKUP_FAILURE to MEMCACHED_HOST_LOOKUP_FAILURE.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

[+] affected symbols (36)
