Problems with Data Types, Medium Severity (4)

	Change	Effect
1	Type of field version has been changed from char[12] (12 bytes) to char[24] (24 bytes).	1) This field may be incorrectly initialized or accessed by applications. 2) Size of the inclusive type has been changed.

	Change	Effect
1	Value of member MEMCACHED_BEHAVIOR_HASH_WITH_PREFIX_KEY has been changed from 24 to 25.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Value of member MEMCACHED_BEHAVIOR_NOREPLY has been changed from 25 to 26.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
3	Value of member MEMCACHED_BEHAVIOR_USE_UDP has been changed from 26 to 27.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Data Types, Low Severity (5)

	Change	Effect
1	Field io_key_prefetch has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type 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	Field next_distribution_rebuild has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type 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.
3	Size of this type has been changed from 556 bytes to 564 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 140 bytes to 152 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Value of member MEMCACHED_MAXIMUM_RETURN has been changed from 34 to 35.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

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

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

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

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

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

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

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