Problems with Data Types, Medium Severity 7

	Change	Effect
1	Field eventingpath 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 alt_svc has been changed from 112 bytes to 136 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 has been changed from 112 bytes to 136 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.
4	Size of field svc_ssl has been changed from 112 bytes to 136 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 5

	Change	Effect
1	Value of member LCB_HTTP_TYPE_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	Value of member LCBVB_SVCTYPE__MAX has been changed from 8 to 9.	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 616 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 112 bytes to 136 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Type of field hoststrs has been changed from *char[8] to char[9]*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

Problems with Constants, Low Severity 1

	Change	Effect
1	The value of constant LCB_CNTL__MAX has been changed from 0x63 to 0x64.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
