Problems with Symbols, High Severity 6

	Change	Effect
1	The parameter outSz became passed in rax register instead of rdx.	Applications will read the wrong memory block instead of the parameter value.
2	The parameter output became passed in r12 register instead of rbp.	Applications will read the wrong memory block instead of the parameter value.
3	The parameter ssl became passed in rdi register instead of rbx.	Applications will read the wrong memory block instead of the parameter value.

	Change	Effect
1	The parameter hash became passed in rsi register instead of rbp.	Applications will read the wrong memory block instead of the parameter value.

	Change	Effect
1	The parameter list became passed in r15 register instead of rbp.	Applications will read the wrong memory block instead of the parameter value.
2	The parameter ssl became passed in r13 register instead of r12.	Applications will read the wrong memory block instead of the parameter value.

Problems with Data Types, Medium Severity 7

	Change	Effect
1	The relative position of field consumed has been changed from 2 to 0.	Applications will access incorrect memory when attempting to access this field.
2	The relative position of field passwd_cb has been changed from 0 to 1.	Applications will access incorrect memory when attempting to access this field.
3	The relative position of field passwd_userdata has been changed from 1 to 2.	Applications will access incorrect memory when attempting to access this field.

	Change	Effect
1	Field lastDateAsn1 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 nextDateAsn1 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 alpn_peer_requested_length 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 currentEntry 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 Symbols, Medium Severity 1

	Change	Effect
1	Parameter cb of type int()(WOLFSSL_X509 constconst, WOLFSSL_X509 constconst*) has been added to the calling stack.	This parameter will not be initialized by old clients.

Problems with Data Types, Low Severity 3

	Change	Effect
1	Size of this type has been changed from 192 bytes to 272 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field alpn_client_list has been renamed to alpn_peer_requested.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 64 bytes to 72 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
