Problems with Symbols, High Severity 3

	Change	Effect
1	The pointer level of 2nd parameter timestamp has been increased from 0 to 1.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

	Change	Effect
1	The pointer level of 3rd parameter current_time has been increased from 0 to 1.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

Problems with Data Types, Medium Severity 3

	Change	Effect
1	Field server_pid 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.

	Change	Effect
1	Field ellipsis 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	Field max_line_length 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.

Problems with Data Types, Low Severity 5

	Change	Effect
1	Size of this type has been changed from 1512 bytes to 1520 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 8304 bytes to 8320 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field use_journal 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.

	Change	Effect
1	Base type has been changed from void()(int32_t, struct qb_log_callsite, time_t, char const) to void()(int32_t, struct qb_log_callsite, struct timespec, char const*).	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type has been changed from void()(int32_t, struct qb_log_callsite, time_t, struct __va_list_tag) to void()(int32_t, struct qb_log_callsite, struct timespec, struct __va_list_tag*).	Replacement of the base data type may indicate a change in its semantic meaning.

Problems with Symbols, Low Severity 5

	Change	Effect
1	Type of 2nd parameter timestamp has been changed from time_t to struct timespec*.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from void to int (4 bytes).	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 3rd parameter current_time has been changed from time_t to struct timespec*.	Replacement of parameter data type may indicate a change in its semantic meaning.
2	3rd parameter current_time has been renamed to the_ts.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 2nd parameter timestamp has been changed from time_t to struct timespec*.	Replacement of parameter data type may indicate a change in its semantic meaning.
