Problems with Data Types, Low Severity 9

	Change	Effect
1	Field client_id 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	Size of this type has been changed from 272 bytes to 280 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field conn_host 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 peer_lost 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 72 bytes to 88 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 pcmk_pacemakerd_state_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	Field active_node 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	Size of this type has been changed from 80 bytes to 88 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	Base type of field is_filtered has been changed from gboolean()(pe_resource_t, GList, gboolean) to gboolean()(pe_resource_t const, GList, gboolean).	Replacement of field base type may indicate a change in the semantic meaning of the field.
