Problems with Data Types, Medium Severity 3

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

	Change	Effect
1	Field server_timeout_counter 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.
2	Field server_timeout_counter_query_id 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 6

	Change	Effect
1	Value of member MEMCACHED_BEHAVIOR_MAX has been changed from 37 to 38.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Base type has been changed from enum memcached_return_t()(memcached_st const, memcached_server_instance_st, void) to enum memcached_return_t()(memcached_st const, memcached_instance_st const, void*).	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type has been changed from enum memcached_return_t()(memcached_server_instance_st, char const, size_t, char const, size_t, void) to enum memcached_return_t()(memcached_instance_st const, char const, size_t, char const, size_t, void*).	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type of field last_disconnected_server has been changed from struct org::libmemcached::Instance to struct memcached_instance_st.	Replacement of field base type may indicate a change in the semantic meaning of the field.
2	Base type of field servers has been changed from struct org::libmemcached::Instance to struct memcached_instance_st.	Replacement of field base type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 1152 bytes to 1168 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
