Problems with Symbols, High Severity (3)

	Change	Effect
1	Type of 2nd parameter level has been changed from int (4 bytes) to uint8_t (1 byte).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Data Types, Medium Severity (5)

	Change	Effect
1	Value of member crm_ipc_client_response has been changed from 1 to 512.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Value of member crm_ipc_compressed has been changed from 2 to 1.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Type of field rc has been changed from enum lrmd_exec_rc to enum ocf_exitcode of different format.	This field may be incorrectly initialized or accessed by applications.

	Change	Effect
1	Field unseen 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 migrating has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Parameter is_remote of type gboolean has been added to the calling stack.	This parameter will not be initialized by old clients.

to the top

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Name of member with value 0 has been changed from crm_ipc_client_none to crm_ipc_flags_none.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Field allowed 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 32 bytes to 40 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 104 bytes to 96 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants, Low Severity (1)

	Change	Effect
1	The value of constant CRM_FEATURE_SET has been changed from "3.0.7" to "3.0.8".	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.
