+

+ + + + + + + + + + + + + + + + + + +

	Change	Effect
1	Field cbaspath 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	Size of field svc has been changed from 96 bytes to 112 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
3	Size of field svc_ssl has been changed from 96 bytes to 112 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity 6

	Change	Effect
1	Value of member LCB_HTTP_TYPE_MAX has been changed from 5 to 6.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Value of member LCBVB_SVCTYPE__MAX has been changed from 7 to 8.	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 240 bytes to 280 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

+couchbase.h
+ +[+] enum lcb_http_type_t 1 +
+ + +
+vbucket.h
+ +[+] enum lcbvb_SVCTYPE 1 +
+ + + +[+] struct lcbvb_SERVER 1 +
+ + + +[+] struct lcbvb_SERVICES 3 +
+

+ + + + + + + + + + + + + + + + + + +

	Change	Effect
1	Size of this type has been changed from 96 bytes to 112 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field cbas has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Type of field hoststrs has been changed from *char[7] to char[8]*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
