Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field dead_timeout 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.

[+] struct memcached_st (1)

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Value of member MEMCACHED_BEHAVIOR_MAX has been changed from 36 to 37.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Size of this type has been changed from 512 bytes to 516 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field no_reply has been renamed to reply.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Value of member MEMCACHED_MAXIMUM_RETURN has been changed from 48 to 49.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

[+] enum memcached_return_t (1)

to the top

Problems with Constants, Low Severity (2)

	Change	Effect
1	The constant MEMCACHED_CONNECTION_MAX with value 0 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant MEMCACHED_CONNECTION_UNKNOWN with value 0 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

Other Changes in Data Types (2)

	Change	Effect
1	The member MEMCACHED_BEHAVIOR_DEAD_TIMEOUT with value 36 has been added.	No effect.

	Change	Effect
1	The member MEMCACHED_SERVER_MEMORY_ALLOCATION_FAILURE with value 48 has been added.	No effect.

Other Changes in Constants (1)

	Change	Effect
1	The constant MEMCACHED_SERVER_FAILURE_DEAD_TIMEOUT with value 0 has been added.	No effect.
