Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Field auth_mask 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 interpret 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.
3	Field protocol 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 (12)

	Change	Effect
1	Field pwsi 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 84 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

2	Field max_http_header_data2 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	Field pt_serv_buf_size 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.
4	Field ssl_options_clear 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.

	Change	Effect
1	Size of this type has been changed from 36 bytes to 48 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field mount_next became const.	The value of this field is expected to be const in new library version, but can be modified by old applications.
3	Type of field mount_next has been changed from struct lws_http_mount* to struct lws_http_mount const*.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
